DECISIONS ON DISAGREEMENTS: 9.9 ENGINEER will be the initial interpreter of the requirements of the Contract Documents and judge of the acceptability of the Work thereunder.Claims,disputes,and other matters relating to the acceptability of the Work,or the interpretation of the requirements of the Contract Documents pertaining to the execution and progress of the Work,shall be referred initially to ENGINEER in writing with a request for a formal decision which ENGINEER will render in writing within a reasonable time. LIMITATIONS ON ENGINEER’S RESPONSIBILITIES: 9.10 Neither ENGINEER’S authority to act under this Article 9,or elsewhere in the Contract Documents,nor any decision made by ENGINEER in good faith either to exercise or not exercise such authority shall give rise to any duty or responsibility of ENGINEER to CONTRACTOR,any Subcontractor,any manufacturer, fabricator,supplier,or distributor,or any of their agents or employees,or any other person performing any of the Work. 9.1 1 Whenever,in the Contract Documents,the terms “as ordered”,“as directed”,“as required”,“as allowed”,or terms of like effect or import are used,or the adjectives “reasonable”,“suitable”,“acceptable”,“proper”,or “satisfactory”,or adjectives of like effect or import are used to describe requirement,direction,review,or judgment of ENGINEER as to the Work,it is intended that such requirement direction,review,or judgment will be solely to evaluate the Work for compliance with the Contract Documents (unless there is a specific statement indicating otherwise).The use of any such term or adjective never indicates that ENGINEER shall 15 have authority to supervise or direct performance of the Work,or authority to undertake responsibility contrary to the provisions of paragraphs 9.12 or 9.13. 9.12 ENGINEER will not be responsible for CONTRACTOR’S means,methods,techniques,sequences or procedures of construction,or the safety precautions and programs incident thereto,and ENGINEER will not be responsible for CONTRACTORS failure to perform the Work in accordance with the Contract Documents. 9.13 ENGINEER will not be responsible for the acts or omissions of CONTRACTOR,or of any Subcontractor,or of the agents or employees of any CONTRACTOR or Subcontractor,or of any other persons at the site or otherwise performing any of the Work. ARTICLE 10 -CHANGES IN THE WORK 10.1 Without invalidating the Agreement,OWNER may,at any time or from time to time,order additions, deletions,or revisions in the Work;these will be authorized by change orders.Upon receipt of a change order, CONTRACTOR shall proceed with the Work involved.All such Work shall be executed under the applicable conditions of the Contract Documents.If any change order causes an increase or decrease in the Contract Price,or an extension or shortening of the Contract Time,an equitable adjustment will be made as provided in Article 11 or Article 12 on the basis of a claim made by either party. 10.2 ENGINEER may authorize minor changes in the Work,not involving an adjustment in the Contract Price or the Contract Time,which are consistent with the overall intent of the Contract Documents.These may be accomplished by a field order,and shall be binding on OWNER,and also on CONTRACTOR who shall perform the change promptly.If CONTRACTOR believes that a field order justifies an increase in the Contract Price or Contract Time,CONTRACTOR may make a claim therefore as provided in Article 11 or Article 12. 10.3 Additional Work performed without authorization of a change order will not entitle CONTRACTOR to an increase in the Contract Price,or an extension of the Contract Time,except in the case of an emergency as provided in paragraph 6.23,and except as provided in paragraphs 10.2 and 13.9. 10.4 OWNER shall execute appropriate change orders prepared by ENGINEER covering changes in the Work which are required by OWNER,or required because of unforeseen physical conditions or emergencies,or because of uncovering Work found not to be defective,or as provided in paragraphs 11.10 or 11.11. 10.5 If notice of any change affecting the general scope of the Work or change in the Contract Price is required by the provisions of any bond to be given to the surety,it will be CONTRACTOR’S responsibility to so notify the surety,and the amount of each applicable bond shall be adjusted accordingly.CONTRACTOR shall furnish proof of such adjustment to OWNER. ARTICLE 11-CHANGE OF CONTRACT PRICE 11.1 The Contract Price constitutes the total compensation (subject to authorized adjustments)payable to CONTRACTOR for performing the Work.All duties,responsibilities,and obligations assigned to or undertaken by CONTRACTOR shall be at his expense without change in the Contract Price. 11.2 The Contract Price may only be changed by a change order.Any claim for an increase in the Contract Price shall be based on written notice delivered to OWNER and ENGINEER within ten days of the occurrence of the event giving rise to the claim.Any change in the Contract Price resulting from any such claim shall be incorporated in a change order. 16 1 1.3 No change orders or other form of order or directive which requires additional compensable Work to be performed may be issued or be effective unless accompanied by a written assurance to the CONTRACTOR that lawful appropriations to cover the costs of the additional Work have been made. 1 1.4 The value of any Work covered by a change order,or of any claim for an increase or decrease in the Contract Price,shall be determined in one of the following ways: 11.4.1 Where the Work involved is covered by unit prices contained in the Contract Documents,by application of unit prices to the quantities of the items involved (subject to the provisions of paragraph 11.10). 11.4.2 By mutual acceptance of a lump sum. 11.4.3 On the basis of the cost of the Work (determined as provided in paragraphs 11.5 and 11.6),plus a contractor’s Fee for overhead and profit (determined as provided in paragraph 11.7). 11 .5 The term “Cost of the Work”means the sum of any and all costs necessarily incurred and paid by CONTRACTOR in the proper performance of the Work.Except as otherwise may be agreed to in writing by OWNER,such costs shall be in amounts no higher than those prevailing in the locality of the Project,shall include only the following items,and shall not include any of the costs itemized in paragraph 11.6: 11.5.1 Payroll costs for employees in the direct employ of CONTRACTOR in the performance of the Work under schedules of job classifications agreed upon by OWNER and CONTRACTOR.Payroll costs for employees not employed full time on the Work shall be apportioned on the basis of their time spent on the Work.Payroll costs shall include,but not be limited to,salaries and wages,plus the cost of fringe benefits which shall include social security contributions,unemployment,excise and payroll taxes,worker’s or workmen’s compensation,health and retirement benefits,bonuses,sick leave, vacation and holiday pay applicable thereto.Such employees shall include superintendents and foremen at the site.The expenses of performing Work after regular working hours,or on Sunday or legal holidays,shall be included in the above only to the extent authorized by OWNER. 11.5.2 Cost of all materials and equipment furnished and incorporated in the Work,including costs of transportation and storage thereof,and manufacturers’field services required in connection therewith. All cash discounts shall accrue to CONTRACTOR unless OWNER deposits funds with CONTRACTOR with which to make payments,in which case,the cash discounts shall accrue to OWNER.All trade discounts,rebates and refunds,and all returns from sale of surplus materials and equipment shall accrue to OWNER,and CONTRACTOR shall make provisions so that they may be obtained. 11.5.3 Payments made by CONTRACTOR to the Subcontractors for Work performed by Subcontractors.If required by OWNER,CONTRACTOR shall obtain competitive bids from Subcontractors acceptable to CONTRACTOR,and shall deliver such bids to OWNER,who will then determine,with the advice of ENGINEER,which bids will be accepted.If a subcontract provides that the Subcontractor is to be paid on the basis of Cost of the Work Plus a Fee,the Subcontractor’s Cost of the Work shall be determined in the same manner as CONTRACTOR’S Cost of the Work.All Subcontracts shall be subject to the other provisions of the Contract Documents insofar as applicable. 11.5.4 Supplemental costs including the following: 11.5.4.1 The proportion of necessary transportation,travel,and subsistence expenses of CONTRACTOR’S employees incurred in discharge of duties connected with the Work. 17 11.5.4.2 Cost,including transportation and maintenance,of all materials,supplies,equipment, machines,appliances,office and temporary facilities at the site,and hand tools not owned by the workmen,which are consumed in the performance of the Work,and cost less market value of such items used but not consumed which remain the property of CONTRACTOR. 11.5.4.3 Rentals of all construction equipment and machinery,and the parts thereof,whether rented from CONTRACTOR or others in accordance with rental agreements approved by OWNER with the advice of ENGINEER,and the costs of transportation,loading,unloading, installation,dismantling and removal thereof,all in accordance with terms of said rental agreements.The rental of any such equipment,machinery or parts shall cease when the use thereof is no longer necessary for the Work. 11.5.4.4 Sales,use,or similar taxes related to the Work,and for which CONTRACTOR is liable, imposed by any governmental authority. 11.5.4.5 Deposits lost for causes other than CONTRACTOR’S negligence,royalty payments,and fees for permits and licenses. 11.5.4.6 Losses and damages (and related expenses),not compensated by insurance or otherwise,to the Work otherwise sustained by CONTRACTOR in connection with the execution of the Work, provided they have resulted from causes other than the negligence of CONTRACTOR,any Subcontractor,or anyone directly or indirectly employed by any of them,or for whose acts any of them may be liable.Such losses shall include settlements made with the written consent and approval of OWNER.No such losses,damages,and expenses shall be included in the Cost of the Work for the purpose of determining Contractor’s Fee.If,however,any such loss or damage requires reconstruction,and CONTRACTOR is placed in charge thereof, CONTRACTOR shall be paid for services a fee proportionate to that stated in paragraph 11.7.2. 11.5.4.7 The cost of

anyone directly or indirectly employed by any of them,or for whose acts any of them may be liable,including,but not limited to, the correction of defective Work,disposal of materials or equipment wrongly supplied,and making good any damage to property. 11.6.6 Other overhead or general expense costs of any kind,and the costs of any item not specifically and expressly included in paragraph 11.5. CONTRACTOR’S FEE: 11.7 The Contractor’s Fee allowed to CONTRACTOR for overhead and profit shall be determined as follows: 11.7.1 a mutually acceptable fixed fee;or,if none can be agreed upon, 11.7.2 a fee based on the following percentages of the various portions of the Cost of the Work: 1 1.7.2.1 for costs incurred under paragraphs 11.5.1 and 1 1 .5.2,the Contractor’s Fee shall be ten percent, 11.7.2.2 for costs incurred under paragraph 11.5.3,the Contractor’s Fee shall be five percent;and if a subcontract is on the basis of Cost of the Work Plus a Fee,the maximum allowable to the subcontractor as a fee for overhead and profit shall be ten percent,and 11.7.2.3 no fee shall be payable on the basis of costs itemized under paragraphs 11.5.4 and 11.6. 11.8 The amount of credit to be allowed by CONTRACTOR to OWNER for any such change which results in a net decrease in cost will be the amount of the actual net decrease.When both additions and credits are involved in any one change,the combined adjustment to overhead and profit shall be figured on the basis of the net increase or decrease in allowable costs,if any. ADJUSTMENT OF UNIT PRICES: 11.9 Whenever the cost of any Work is to be determined based upon unit price,CONTRACTOR will submit,in form acceptable to ENGINEER,an itemized cost breakdown together with supporting data. 11.10 Where the quantity of Work with respect to any item that is covered by a unit price differs materially and significantly from the quantity of such Work indicated in the Contract Documents,an appropriate change order (additive or deductive)may be issued on recommendation of ENGINEER.In no event will the unit price bid by CONTRACTOR be modified,but the quantity of any item may be increased or decreased as set forth herein.In no event will the Contract Price be modified without a change order approved by OWNER. CASH ALLOWANCES: 11.11 It is understood that CONTRACTOR has included in the Contract Price all allowances so named in the Contract Documents,and shall cause the Work so covered to be done by such Subcontractors,manufacturers, 19 fabricators,supp]iers,or distributors,and for such sums within the limit of the allowances as may be acceptable to ENGINEER.Upon final payment,the Contract Price shall be adjust as required,and an appropriate change order issued.CONTRACTOR agrees that the original Contract Price includes such sums as CONTRACTOR deems proper for costs and profit on account of cash allowances.No demand for additional cost or profit in connection therewith will be valid. ARTICLE 12 -CHANGE Of THE CONTRACT TIME 12.1 The Contract Time may only be changed by a change order.Any claim for an extension in the Contract Time shall be based on written notice delivered to OWNER and ENGINEER within ten days of the occurrence of the event giving rise to the claim.Any change in the Contract Time resulting from any such claim shall be incorporated in a change order. 12.2 All time limits stated in the Contract Documents are of the essence of the Agreement.The provisions of Articles 11 and 12 are CONTRACTORS sole remedies for delay by any cause whatsoever,including acts of OWNER. ARTICLE 13-WARRANTY AND GUARANTEE;TESTS AND INSPECTION;CORRECTION,REMOVAL OR ACCEPTANCE OF DEFECTIVE WORK WARRANTY AND GUARANTEE: 13.1 CONTRACTOR warrants and guarantees to OWNER and ENGINEER that all Work will be in accordance with the Contract Documents and will not be defective.Prompt notice of all defects shall be given to CONTRACTOR.All defective Work,whether or not in place,may be rejected,corrected,or accepted as provided in this Article 13. ACCESS TO WORK: 13.2 ENGINEER,ENGINEER’S representatives,other representatives of OWNER,testing agencies,and governmental agencies with jurisdictional interests will have access to the Work at reasonable times for their observation,inspection and testing.CONTRACTOR shall provide proper and safe conditions for such access. TESTS AND INSPECTIONS: 13.3 CONTRACTOR shall give ENGINEER timely notice of readiness of work for all required inspections,tests or approvals. 13.4 If any law,ordinance,rule,regulation,code,or order of any public body having jurisdiction requires any Work (or part thereof)to specifically be inspected,tested,or approved,CONTRACTOR shall assume full responsibility therefore,pay all costs in connection therewith,and furnish ENGINEER the required certificates of inspection,testing,or approval.CONTRACTOR shall also be responsible for and shall pay all costs in connection with any inspection or testing required in connection with OWNER’S or ENGINEER’S acceptance of a manufacturer,fabricator,supplier or distributor of materials or equipment proposed to be incorporated in the Work,or of materials or equipment submitted for approval prior to CONTRACTOR’S purchase thereof for incorporation of the Work.The cost of all other inspections,tests,and approvals required by the Contract Documents shall be paid by OWNER (unless otherwise specified). 20 13.5 Any inspections,tests,or approvals,other than those required by law,ordinance,rule,regulation,code,or order of any public body having jurisdiction,shall be performed by organizations acceptable to OWNER and CONTRACTOR (or by ENGINEER if so specified). 13.6 If any Work that is to be inspected,tested,or approved is covered without written concurrence of ENGINEER, it must,if requested by ENGINEER,be uncovered for observation.Such uncovering shall be at CONTRACTOR’S expense,unless CONTRACTOR has given ENGINEER timely notice of CONTRACTOR’S intention to cover such Work and ENGINEER has not acted with reasonable promptness in response to such notice. 13.7 Neither observations by ENGINEER nor inspections,tests,or approvals by others shall relieve CONTRACTOR from his obligations to perform the Work in accordance with the Contract Documents. UNCOVERING WORK: 13.8 If any Work is covered contrary to the written request of ENGINEER,it must,if requested by ENGINEER,be uncovered for ENGINEER’S observation and replaced at CONTRACTOR’S expense. 13.9 If ENGINEER considers it necessary or advisable that covered Work be observed by ENGINEER,or inspected or tested by others,CONTRACTOR,at ENGINEER’S request,shall uncover,expose,or otherwise make available for observation,inspection,or testing as ENGINEER may require,that portion of the Work in question,furnish all necessary labor,material,and equipment.If it is found that such Work is defective, CONTRACTOR shall bear all the expenses of such uncovering,exposure,observation,inspection,and testing of satisfactory reconstruction,including compensation for additional professional services,and an appropriate deductive change order shall be issued.If,however,such Work is not found to be defective,CONTRACTOR shall be allowed an increase in the Contract Price,or an extension of the Contract Time,or both,directly attributable to such uncovering,exposure,observation,inspection,testing,and reconstruction. OWNER MAY STOP THE WORK: 13.10 If the Work is defective,or CONTRACTOR fails to supply sufficient skilled workmen or suitable materials or equipment,OWNER may order CONTRACTOR to stop the Work,or any portion thereof,until the cause for such order has been eliminated;however,this right of OWNER to stop the Work shall not give rise to any duty on the part of OWNER to exercise this right for the benefit of CONTRACTOR or any other party. CORRECTION OR REMOVAL Of DEFECTIVE WORK: 13.11 If required by ENGINEER,CONTRACTOR shall promptly,without cost to OWNER and as specified by ENGINEER,either correct any defective Work,whether or not fabricated,installed,or completed,or,if the Work has been rejected by ENGINEER,remove it from the site and replace it with nondefective Work in a manner acceptable to the ENGINEER. TWO YEAR CORRECTION PERIOD: 13.12 If,within two years after the date of substantial completion,or such longer period of time as may be prescribed by law,or by the terms of any applicable special guarantee required by the Contract Documents,or by any other specific provision of the Contract Documents,any Work is found to be defective, CONTRACTOR shall promptly,without cost to OWNER,and in accordance with OWNER’S written instructions,either correct such defective Work,or,if it has been rejected by OWNER,remove it from the site, and replace it with nondefective Work.If CONTRACTOR does not promptly comply with the terms of such instructions,or in an emergency where delay would cause serious risk of loss or damage,OWNER may have the defective Work corrected or the rejected Work removed and replaced,and all direct and indirect costs of 21 such removal and replacement,including compensation for additional professional services,shall be paid by CONTRACTOR. ACCEPTANCE OF DEFECTIVE WORK: 13.13 If,instead of requiring correction or removal and replacement of defective Work,OWNER (and,prior to ENGINEER’S recommendation of final payment,)prefers to accept it,OWNER may do so.In such case,if acceptance occurs prior to ENGINEERS recommendation of final payment,a change order shall be issued incorporating the necessary revisions in the Contract Price;or,if the acceptance occurs after such recommendation,an appropriate amount shall be paid by CONTRACTOR to OWNER. OWNER MAY CORRECT DEFECTIVE WORK: 13.14 If CONTRACTOR fails,within a reasonable time after written notice of ENGINEER,to proceed to correct defective Work,or to remove and replace rejected Work as required by ENGINEER in accordance with paragraph 13.11,or if CONTRACTOR fails to perform the Work in accordance with the Contract Documents (including any requirements of the progress schedule),OWNER may,after seven days written notice to CONTRACTOR,correct and remedy any such deficiency.In exercising his rights under this paragraph OWNER shall proceed expeditiously.To the extent necessary to complete corrective and remedial action, OWNER may exclude CONTRACTOR from all part of the site,take possession of all or part of the Work,and suspend CONTRACTOR’S services related thereto,take possession of CONTRACTOR’S tools,appliances, construction equipment,and machinery at the site,and incorporate in the Work all materials and equipment stored at the site,or for which OWNER has paid CONTRACTOR,but which are stored elsewhere. CONTRACTOR shall allow OWNER,OWNER’S representatives,agents,and employees such access to the site as may be necessary to enable OWNER to exercise his rights under this paragraph.All direct and indirect costs of OWNER in exercising such rights shall be charged against CONTRACTOR in an amount verified by ENGINEER,and a change order shall be issued incorporating the necessary revisions in the Contract Documents and a reduction in the Contract Price.Such direct and indirect costs shall include,in particular but without limitation,compensation for additional professional services required,and all costs of repair and replacement of work of others destroyed or damaged by correction,removal,or replacement of CONTRACTOR’S defective Work.CONTRACTOR shall not be allowed an extension of the Contract Time because of any delay in performance of the Work attributable to the exercise by OWNER of OWNER’S rights hereunder. ARTICLE 14-PAYMENTS TO CONTRACTOR AND COMPLETION SCHEDULES: 14.1 At least ten days prior to submitting the first application for a progress payment,CONTRACTOR shall (except as otherwise specified in the general requirements)submit to ENGINEER a progress schedule,a final schedule of shop drawing submissions,and,where applicable,a schedule of values of the Work.These schedules shall be satisfactory in form and substance to ENGINEER.The schedule of values shall include quantities and unit prices aggregating the Contract Price,and shall subdivide the Work into component parts in sufficient detail to serve as the basis for progress payments during construction.Upon acceptance of the schedule of values by ENGINEER,it shall be incorporated into a form of application for payment acceptable to ENGINEER. APPLICATION FOR PROGRESS PAYMENT: 14.2 At least ten days before each progress payment falls due (but not more often than once a month), CONTRACTOR shall submit to ENGINEER for review an application for payment filled out and signed by 22 CONTRACTOR covering the Work completed as of the date of the application,and accompanied by such supporting documentation as is required by the Contract Documents,and also as ENGINEER may reasonably require.If payment is requested on the basis of materials and equipment not incorporated in the Work,but delivered and suitably stored at the site or at another location agreed to in writing,the application for payment shall also be accompanied by such data,satisfactory to OWNER,as will establish OWNERS title to the material and equipment,and protect OWNERS interest therein,including applicable insurance.Each subsequent application for payment shall include an affidavit of CONTRACTOR stating that all previous progress payments received on account of the Work have been applied to discharge in full all of CONTRACTOR’S obligations reflected in prior applications for payment.The amount of retainage with respect to progress payments will be as stipulated in the Agreement. CONTRACTORS WARRANTY OF TITLE: 14.3 CONTRACTOR warrants and guarantees that title to all Work,materials,and equipment covered by any application for payment,whether incorporated in the Project or not,will pass to OWNER at the time of payment free and clear of all liens,claims,security interests,and encumbrances (hereafter in these General Conditions referred to as “Liens”). REVIEW OF APPLICATIONS FOR PROGRESS PAYMENT: 14.4 ENGINEER will,within ten days after receipt of each application for payment,either indicate in writing a recommendation of payment and present the application to OWNER,or return the application to CONTRACTOR indicating in writing ENGINEER’S reasons for refusing to recommend payment.In the latter case,CONTRACTOR may make the necessary corrections and resubmit the application.OWNER shall, within twenty days of presentation to him of the application for payment with ENGINEER’S recommendation, pay CONTRACTOR the amount recommended. 14.5 ENGINEER’S recommendation of any payment requested in an application for payment will constitute a representation by ENGINEER to OWNER that,based on ENGINEER’S on-site observations of the Work in progress as an experienced and qualified design professional,and on ENGINEER’S review of the application for payment,and the accompanying data and schedules,the Work has progressed to the point indicated;that, to the best of ENGINEER’S knowledge,information,and belief,the quality of the Work is in accordance with the Contract Documents (subject to an evaluation of the Work as a functioning Project upon substantial completion,and to the results of any subsequent tests called for in the Contract Documents and any qualifications stated in the recommendation);and,that CONTRACTOR is entitled to payment of the amount recommended.However,by recommending any such payment,ENGINEER will not thereby be deemed to have represented that exhaustive or continuous on-site inspections have been made to check the quality or the quantity of Work,or that the means,methods,techniques,sequences,and procedures of construction have been reviewed,or that any examination has been made to ascertain how or for what purpose CONTRACTOR has used the monies paid or to be paid to CONTRACTOR on account of the contract price,or that title to any Work,materials,or equipment has passed to OWNER free and clear of any Liens. 14.6 ENGINEER’S recommendation of final payment will constitute an additional representation by ENGINEER to OWNER that the conditions precedent to CONTRACTOR’S being entitled to final payment as set forth in paragraph 14.13 have been fulfilled. 14.7 ENGINEER may refuse to recommend the whole,or any part of any payment if,in his opinion,it would be incorrect to make such representations to OWNER.He may also refuse to recommend any such payment,or, because of subsequently discovered evidence,or the results of subsequent inspections or tests,nullify any such payment previously recommended to such extent as may be necessary in ENGINEER’S opinion to protect OWNER from loss because: 14.7.1 the work is defective,or completed Work has been damaged requiring correction or replacement, 23 14.7.2 written claims have been made against OWNER,or Liens have been filed in connection with the Work, 14.7.3 the Contract Price has been reduced because of modifications, 14.7.4 OWNER has been required to correct defective Work,or complete the Work in accordance with paragraph 13.14, 14.7.5 of CONTRACTOR’S unsatisfactory prosecution of the Work in accordance with the Contract Documents,or 14.7.6 CONTRACTOR’S failure to make payment to Subcontractors,or for labor.materials,or equipment. SUBSTANTIAL COMPLETION: 14.8 When CONTRACTOR considers the entire Work ready for its intended use,CONTRACTOR shall,in writing to OWNER and ENGINEER,certify that the entire Work is substantially complete,and request that ENGINEER issue a certificate of substantial completion.Within a reasonable time thereafter,OWNER, CONTRACTOR,and ENGINEER shall make an inspection of the Work to determine the status of completion.If ENGINEER does not consider the Work substantially complete,ENGINEER will notify CONTRACTOR in writing giving his reasons therefor.If ENGINEER considers the Work substantially complete,ENGINEER will prepare and deliver to OWNER a tentative certificate of substantial completion which shall fix the date of substantial completion.There shall be attached to the certificate a tentative list of items to be completed or corrected before final payment.OWNER shall have seven days after receipt of the tentative certificate during which he may make written objection to ENGINEER as to any provisions of the certificate or attached list.If,after considering such objections,ENGINEER concludes that the Work is not substantially complete,ENGINEER will,within fourteen days after submission of the tentative certificate to OWNER,notify CONTRACTOR in writing stating his reasons therefor.If,after consideration of OWNER’S objections,ENGINEER considers the Work substantially complete,ENGINEER will,within said fourteen days,execute and deliver to OWNER and CONTRACTOR a definitive certificate of substantial completion (with a revised tentative list of items to be completed or corrected)reflecting such changes from the tentative certificate as he believes justified after consideration of any objections from OWNER At the time of delivery of tentative certificate of substantial completion,ENGINEER will deliver to OWNER and CONTRACTOR a written recommendation as to division of responsibilities pending final payment between OWNER and CONTRACTOR with respect to security,operation,safety,maintenance,heat,utilities,and insurance.Unless OWNER and CONTRACTOR agree otherwise in writing and so inform ENGINEER prior to his issuing the definitive certificate of substantial completion,ENGINEER’S aforesaid recommendation will be binding on OWNER and CONTRACTOR until final payment. 14.9 OWNER shall have the right to exclude CONTRACTOR from the Work after the date of substantial completion,but OWNER shall allow CONTRACTOR reasonable access to complete or correct items on the tentative list.

FINAL INSPECTION: 14.11 Upon written notice from CONTRACTOR that the Work is complete,ENGINEER will make a final inspection with OWNER and CONTRACTOR,and will notify CONTRACTOR in writing of all particulars in which this inspection reveals that the Work is incomplete or defective.CONTRACTOR shall immediately take such measures as are necessary to remedy such deficiencies. FINAL APPLICATION FOR PAYMENT: 14.12 After CONTRACTOR has completed all such corrections to the satisfaction of ENGINEER,and delivered all maintenance and operating instructions,schedules,guarantees,bonds,certificates of inspection,marked-up record documents,and other documents,all as required by the Contract Documents,and after ENGINEER has indicated that the Work is acceptable (subject to the provisions of paragraph 14.14),CONTRACTOR may make application for final payment following the procedure for progress payments.The final application for payment shall be accompanied by all documentation called for in the Contract Documents,and such other data and schedules as ENGINEER may reasonably require,together with complete and legally effective releases or waivers (satisfactory to OWNER)of all liens arising out of,or filed in connection with the Work.In lieu thereof,and as approved by OWNER,CONTRACTOR may furnish receipts or releases in full;an affidavit of CONTRACTOR that the releases and receipts include all labor,services,material,and equipment for which lien could be filed,and that all payrolls,material,and equipment bills,and other indebtedness connected with the Work,for which OWNER or his property might in any way be responsible,have been paid or otherwise satisfied;and consent of the surety,if any,to final payment.If any subcontractor,manufacturer,fabricator, 25 supplier,or distributor fails to furnish a release or receipt in full,CONTRACTOR may furnish a bond or other collateral satisfactory to OWNER to indemnify OWNER against any lien. FINAL PAYMENT AND ACCEPTANCE: 14.13 If,on the basis of ENGINEERS observation of the Work during construction and final inspection,and ENGINEERS review of the final application for payment and accompanying documentation,all as required by Contract Documents,ENGINEER is satisfied that the Work has been completed and CONTRACTOR has fulfilled all of his obligations under the Contract Documents,ENGINEER will,within ten days after receipt of the final application for payment,indicate in writing his recommendation of payment,and present the application to OWNER for payment.Thereupon,ENGINEER will give written notice to OWNER and CONTRACTOR that the Work is acceptable subject to the provisions of paragraph 14.15.Otherwise, ENGINEER will return the application to CONTRACTOR,indicating in writing the reasons for refusing to recommend final payment,in which case CONTRACTOR shall make the necessary corrections,and resubmit the application.If the application and accompanying documentation are appropriate as to form and substance, OWNER shall,within thirty days after receipt thereof,pay CONTRACTOR the amount recommended by ENGINEER. CONTRACTOR’S CONTINUING OBLIGATION: 14.14 CONTRACTOR’S obligation to perform and complete the Work in accordance with the Contract Documents shall be absolute.Neither recommendation of any progress or final payment by ENGINEER,nor the issuance of a certificate of substantial completion,nor any payment by OWNER to CONTRACTOR under the Contract Documents,nor any use or occupancy of the Work or any part thereof by OWNER,nor any act of acceptance by OWNER,nor any failure to do so,nor the issuance of a notice of acceptability by ENGINEER pursuant to paragraph 14.13,nor any correction of defective Work by OWNER shall constitute an acceptance of Work not in accordance with the Contract documents or a release of CONTRACTOR’S obligation to perform the Work in accordance with the Contract Documents. WAIVER OF CLAIMS: 14.15 The making and acceptance of final payment shall constitute: 14.15.1 a waiver of all claims by OWNER against CONTRACTOR,except claims arising from unsettled liens,from defective Work appearing after final inspection pursuant to paragraph 14.11,or from failure to comply with the Contract Documents or the terms of any special guarantees specified therein;however,it shall not constitute a waiver by OWNER of any rights in respect of CONTRACTOR’S continuing obligations under the Contract Documents;and 14.15.2 a waiver of all claims by CONTRACTOR against OWNER other than those previously made in writing and still unsettled.

Revision of Section 504 Concrete Block Facing MSE Walls 9 504.14 Hybrid MSE Wall Systems. A hybrid system is one which combines elements of both externally and internally stabilized systems. An externally stabilized system uses a physical structure to hold the retained soil.The stabilizing forces of this system are mobilized either through the weight of a shape stable structure or through the restraints provided by the embedment of wall into the soil,if needed,plus the tieback forces of anchorages. An internally stabilized system involves reinforced soils to retain fills and sustain loads. Reinforcement may be added to either the selected fills as earth walls or to the retained earth directly to form a more coherent stable slope.These reinforcements can either be layered reinforcements installed during the bottom-to-top construction of selected fills,or be driven piles or drilled caissons built into the retained soil.All this reinforcement must be oriented properly and extend beyond the potential failure mass. Hybrid MSE wall systems may be used unless otherwise noted on the plans.Hybrid MSE wall systems are subject to the same design requirements for MSE walls and this specification.The shop drawings for Hybrid MSE wall system shall include a combination of design calculations and appropriate test results to demonstrate that it meets or exceeds the block facing system.Each unit in the hybrid MSE wall system shall have a facing area of 3.5 square feet and be stabilized by a counterfort.Hybrid MSE wall facing units shall be factory made with Class B Concrete with the following additional requirements: (1)Minimum Cementitious Material Content:610 lb./cu.yd.

Alpine Engineering,Inc. P.O.Box 97 Edwards,CO 81620 SUBJECT:Geotechnical Services for ECO Trails Phases I and 2,Avon to Eagle- Vail,Colorado.MWW&AI Project No.111014. * Dear Mr.Kriehn: Michael W.West &Associates,inc.(MWW&AI)is pleased to present this report describing the results of our geotechnical investigation,stability anaLyses, and recommendations for constrtiction of Eagle County Trails Project (Phases 1 and 2)between Avon and Eagle-Vail,Colorado.The analyses and recommendations contained herein are relevant to the retaining walls along the trail as shown on the “ECO Regional Trail,Avon to Eagle-Vail Phase 1”and “Phase 2” Wall Plan and Profile sheets by Alpine Engineerin,along with Wall cross sections. The Phase 1 Plan and Profile sheets were last modified on October 5,2011,and the Phase 2 sheets were last modified July 14,2011.Analyses and recommendations for the bridge structures over the Eagle River and Beaver Creek will be presented in a future report,as plans have not been finalized for this part of the project. This report presents (1)Objectives and Scope;(2)Project Description;(3) Geologic Setting;(4)Site Investigation;(5)Site Investigations by Others;(6) Subsurface Conditions;(7)Retaining Wall Stability Analyses and Recommendations;(8)Bridge foundation Recommendations —to be presented in a future report;and (9)General Information.Laboratory results are summarized in the table attached to this report.Figures 1 and 2 depict test hole locations as well as locations of cross-sections selected for analysis.Logs of test holes are included as Figures 3 and 4.The laboratory test result data is included in Appendix I.Cross sections for analyses and Stability analyses results are included in Appendix II. MWW&AI issued a separate report related to this project on October 18, 2011 titled “Retaining Wall Alternative Evaluation.”The report that follows is prepared based on the recommendations and alternatives selected in our October 1$,2011 report. Mr.Kent Krielm November 30,2011 Page 2 1.0 OBJECTIVES AND SCOPE We present site observations and the results of our subsurface investigation and global stability analyses relevant to the proposed project retaining walls (Phases 1 and 2).We expect to present geotechnical recommendations related to proposed bridges at Eagle River (Phase 3)and Beaver Creek (included in Phase 1) in a future report.The scope ofwork for Phases 1 and 2 included: 1.Site visits and review of available information,including available geologic mapping and geotechnical investigations performed by others in the area. 2.A field geotechnical investigation with borings located in the vicinity of proposed bridge abutments and retaining walls,augmented by available boring information from previous projects by others. 3.Laboratory testing to determine properties of soils and bedrock materials encountered,and to aid in assignment of strength properties for analysis and design. 4.Global stability analyses of selected cross sections,typically involving proposed retaining walls and existing slopes,including existing Highway 6 embankment or natural slopes between Highway 6 and the Eagle River. 5.Development of recommendations for retaining wall design,including footing depth,minimum reinforcement length (for MSE walls),and pertinent wall details,including edits of the CDOT Standard Special Provision 504 for Block faced MSE Walls. 6.Provide recommendations for bridge foundations and abutments at the Eagle River and Beaver Creek bridges —to be presented in a future report. 2.0 PROJECT AND SITE DESCRIPTION The Eagle County Trails (ECO Trails)Project described by this report is to be completed in 3 Phases.Phase 1 generally extends from Avon east along the north side of Highway 6,and south of the Eagle River to the intersection of Highway 6 and Stone Creek Drive.Phase 1 also includes a bridge crossing over Beaver Creek.Phase 2 extends east of Stone Creek Drive to the project terminus in Eagle-Vail in the vicinity of the US 6/1-70 Interchange.Phase 3 consists of a bridge over the Eagle River in Avon,immediately adjacent to and east of the existing Highway Bridge. The trail alignment is generally along the north side of Highway 6,and traverses relatively steep highway embankment or natural slopes between Highway 6 and the Eagle River through significant portions of the alignment.The relatively steep existing slopes and desire to restrict construction to the current Highway Right of Way (ROW)means that a significant length of retaining wall will be required to construct this trail. Project No.111014 Mr.Kent Krielm November 30,2011 Page 3 In general,our observations suggest that existing embankment and natural slopes north of Highway 6 and above the Eagle River are performing reasonably well.No indications of slope instability were observed at the locations of proposed retaining walls.In general,these slopes are well vegetated (for this environment). In addition,no discernable embankment settlement was apparent. Block-faced MSE walls,in general accordance with CDOT Standard Special Provision 504 (SP 504)are preferred alternative for the Phase I and Phase 2 retaining walls.The steep slopes typically present immediately downhill of these walls means that global stability must be checked for representative wall geometries.As addressed in our October 18,2011 report,some reaches of Phase 2 include “Double Walls,”that is,reaches of the project where a new wall must be constructed in front of and downhill of an existing block faced MSE wall: •Phase 2—Stations 15±25 to 16±75 (150 linear feet),and •Phase 2 —Stations 18+65 to 2 1±25 (260 linear feet). Our October 18 report recommended a micropile supported block wall with lightweight fill for the double wall sections. Alpine’s plans indicate excavation for a conventional MSE wall may encroach into the existing highway in some sections as identified below.The following sections may or may not require special techniques,depending on the actual temporary excavation slope selected by the contractor.The approach to these “non-double wall”sections recommended in our October 18 report is to require the contractor to provide temporary shoring as needed to avoid encroachment.Alternately,a Shored MSE wall (SMSE wall)in accordance with FHWA Publication No.fHWA-CFL/TD-06-OOl may be considered: •Phase 1 —Stations 2±10 to 6+70 (460 linear feet), •Phase 1 —Stations 17±85 to 20±60 (275 linear feet), •Phase 1 —Stations 27+75 to 29+70 (195 linear feet), •Phase 2 —Stations 2 1+25 to 25+50 (425 linear feet),and •Phase 2 —Stations 27±40 to 2 8±60 (120 linear feet). 3.0 GEOLOGIC SETTING 3.1 Bedrock Stratigraphy and Structure The geology of the project area is complicated by its location in a dynamic river valley,along with the presence of evaporite deposits and associated solution activity,which can cause high geologic variability from one boring to the next. Published geologic mapping by Tweto and others (1988)depicts bedrock of the Eagle Valley Evaporite directly underlying the majority of the proposed trail alignment.The Eagle Valley Formation is mapped on the slopes to the north on the Project No.111014 Mr.Kent Kriehn November 30.2011 Page 4 opposite side of the valley and may underlie the site in some places.The Minturn and Belden formations are mapped upsiope to the south and near the east end of the proposed trail alignment,and may also underlie the proposed trail in places. The Eagle Valley Evaporite (Pennsylvanian)is comprised of gypsum, anhydrite.and interbedded siltstone and minor dolomite (Tweto and others,198$). Evaporite deposits contain soluble minerals and are generally relatively soft,poorly covered with vegetation,and prone to erosion (White and Greenman,200$).This unit intertongues with the Mintum,Belden and Maroon formations and grades into the fine-grained clastic rocks of the Eagle Valley formation.The Eagle Valley Evaporite forms diapirs in many locations and the thickness is difficult to determine.Overlying the evaporite deposits is the Eagle Valley formation (Pennsylvanian),which is comprised of gray to reddish-gray sihstone,shale, sandstone,and carbonate rocks,with local lenses of gypsum (Tweto and others, 198$).This unit is transitional between purely evaporitic rocks of the Eagle Valley Evaporite and coarse elastic rocks of the Mintum and Belden Formations.The Minturn formation is generally comprised of gray,pale-yellow,and red sandstone, grit,conglomerate,and shale,with scattered beds and reefs of carbonate rocks.The Belden formation is generally dark-gray to black shale,carbonate rocks,and sandstone. Several faults are also mapped on the slopes to the south and to the northeast of the project (Tweto and others,1988).There is also a fault concealed by river gravels mapped along the valley bottom located at closest approach approximately 1 mile east of the east end of the proposed trail. 3.2 Surficial Deposits Tweto and others (198$)show unconsolidated Pleistocene-age gravels, including stream,terrace,and outwash gravel deposits,in the valley bottom along the Eagle River and the proposed trail alignment.These gravels have an unknown thickness and overlie bedrock for the length of the trail alignment.Personal experience indicates that these deposits also contain cobbles and large boulders. Landslide deposits are mapped on the north-facing slopes of the valley to the southeast,and smaller un-mapped landslide bodies are likely (Tweto and others, 1988).Landslide deposits are characterized by large slump blocks of basalt irregularly veneered with young glacial drift and may include mudflow and talus deposits (Tweto and others,198$). 4.0 GEOTECHNICAL INVESTIGATION 4.1 Subsurface Exploration We designed our drilling program to generally define bedrock,overburden soils,and ground water conditions at or near proposed bridge locations,near high points in the MSE wall and near locations where a steep slope was present. Project No.111014 Mr.Kent Krielm November 30,2011 Page 5 Continuous auger samples,penetration resistance tests and sampling of soil and rock materials aided in the areal and subsurface characterization of geologic and geotechnical conditions at the site.Drill logs for the following borings are provided in Appendix I: •Boring 1 located at the South Abutment of the Proposed Eagle River Bridge;previous boring from CDOT files used for North Abutment. •Boring 2 located at the Beaver Creek crossing. o Borings 3,4,5,and 7 located at selected retaining wall/slope cross- sections along the trail alignment for Phase 1. o Borings 8,10 and 11 located at selected retaining wall/slope cross- sections along the trail alignment for Phase 2,augmented by additional borings from CDOT files for the 1-70/US 6 interchange. Several issues were encountered during execution of this plan.Other than Borings 1 and 2,all borings were planned along the outer (northern)edge of the existing US 6 corridor,on the paved shoulder of the highway and adjacent to the existing guard rail,typically.Retaining wall locations are typically further “out” on the slopes,to the north,but these locations were expected to be (and generally are)reasonable locations to investigate ground conditions for global stability analyses of the retaining walls.However,numerous utilities are present along this shoulder that typically conflicted with these boring locations.Our drilling contractor was able to use vacuum extraction methods,at some additional (unplanned)cost,to penetrate the utility zone,and thus Borings 3,4,5,and 7 were accomplished.Boring 6 was not drilled,as utility conflicts were severe at this location,and the proposed retaining wall location is at considerable distance from any accessible location (near the toe of the highway embankment)-we judged the benefit/cost (as well as benefit/risk)ratio to be poor for this boring. Borings 8,10 and 11 are in Phase 2 and are located in an area currently occupied by an XCEL Energy gas pipeline project.Despite our CDOT permit,we had difficulty accessing these boring locations.We eliminated Boring 9 due to project constraints and because Boring EV-1 I drilled by Yeh (April 27,2001)was located in close proximity to the proposed boring location. We have access to CDOT’s files for the 1-70/US 6 Interchange,and have inspected the existing slopes and embankment in this area.We used data from these files in lieu of drilling Borings 6 and 9. Logs of Borings 1 through 5,7,8,10,and 11 are provided as figures 3 and 4.Borings were advanced using a variety of methods including: o Vacuum extraction through the utility zone (as described above), •Auger drilling (either hollow stem or solid auger)through fills, •ODEX (a down-hole hammer system)for penetrating dense or hard cobbles and boulder deposits,as well as bedrock in some cases,and •Rock coring for bedrock samples. Project No.111014 Mr.Kent Kriehn November 30,2011 Page 6 Drive samples of subsurface materials were generally obtained at approximate 5-foot intervals in each boring.However,the initial sample was deeper than 5 feet in the borings that were started using vacuum extraction. Samples were obtained using a 2-inch inside diameter California-type sampler or a standard Split Barrel sampler.The sampler was driven with a 140-pound hammer falling a vertical distance of 30 inches.The number of blows required to advance the sampler 12 inches was recorded as the penetration resistance value or N value. Sampling was done in general accordance with the Standard Penetration Test (SPT) described by ASTM D1586.Penetration resistance values provide an indication of the relative density of granular soils or consistency of fine-grained soils.Depths at which the samples were obtained and the penetration resistance values are shown on the drill logs (Appendix 1). 4.2 Laboratory Analysis The laboratory testing program was conducted to confirm visual field classifications and to provide specific data on the physical,index and engineering properties for the subsurface materials encountered during our field investigation. Seven samples were sent to Advanced Terra Testing laboratory for analysis.The samples were classified in accordance with ASTM D2487,Classification of Soils for Engineering Purposes,which is based on the Unified Soil Classification System.Laboratory testing performed for this study includes natural moisture content,dry density.Atterberg Limits,and gradation.Laboratory test results are summarized on Table I attached to this report.Laboratory data sheets are included as Appendix II. 5.0 SITE INVESTIGATIONS FROM CDOT FILES 5.1 Eagle River Bridge We have reviewed two sheets of drawings by Ground Engineering Consultants,Inc.(Ground)with a revised date of February 23,1991 for the existing CDOT Highway Bridge over the Eagle River.Plans provided by CDOT include subsurface data obtained from Test Holes 1.2,5.and 6 (geological characterization and laboratory data).According to the sheets provided us,Ground encountered fill and/or native gravel overlying sandstone and siltstone bedrock.F ill was generally around 5 to 15 feet thick and native gravel was typically around 10 to 20 feet thick. Bedrock was encountered at around 20 to 30 feet below ground surface. Groundwater was encountered at around 30 feet below the ground surface in boring 5. Project No.111014 Mr.Kent Krielm November 30,2011 Page 7 5.2 I-7OIUS 6 Interchange Yeh &Associates,Inc.(Yeh)presented results of a geotechnical investigation of existing fill embankments in and around the 1-70/US 6 Interchange in a report dated April 27,2001.Yeh conducted field reconnaissance and exploratory drilling for this investigation,which consisted of nine exploratory borings and five soil survey borings.In general,the subsurface conditions encountered were native material or fill overlying bedrock.The native material was comprised of alluvium and glacial drift,described as medium-dense to dense gravelly sand with silt,clay,cobbles,and boulders.Yeh divided the fill material into two types:(Fill 1)sandy silt with cobbles and gravels,extending to a depth of around 9 feet,loosely placed and most likely originating from construction of adjacent structures;and (Fill 2)loose to medium-dense gravelly silty and clayey sand with some cobbles and boulders,making up the embankments and bridge approach area along 1-70.The bedrock was identified as Mintum Formation, sandstone with interbedded shale and limestone.Yeh encountered groundwater at 2.9 feet in one of their borings and attributed this shallow water level to surface nmoff and snowmelt from 1-70. 6.0 SUBSURFACE CONDITIONS Based on site observations,subsurface investigations performed by us and others,and review of available documents,we describe the materials and conditions encountered at the site as follows: Existing Embankment FiLl:All nine of our borings encountered existing embankment fill,which we associate with past highway construction,Although we divide the fill into two types,these designations are not to be associated with the two types identified by Yeh (April 27,2001): •The first type was encountered in all nine borings and was identified as brown,dark brown or reddish-brown clayey sand with gravel,low plasticity,medium dense,and slightly moist to moist. o Four of the nine borings (TH-1,TH-3,TH4,and TH-5)exhibited a second type of fill underlying the first.The second type was characterized by brown to dark brown sandy clay or sandy silt with gravel,low to medium plasticity,medium dense,and slightly moist to moist. Evaluation of fill density against past or present specifications was beyond the scope of this report;however,penetration resistance and measured densities, along with general observation of fill and embankment performance suggest adequate density and strength. Project No.111014 Mr.Kent Kriehn November 30,201 1 Page 8 Alluvial Deposits:Alluvial deposits were encountered in the borings below the embankment fill.In the borings where bedrock was encountered (TN-i to TH-5), the alluvium varied from 7 to 49 feet thick.The al]uvial deposits were generally comprised of sand and gravel with intervals where cobbles and boulders were common.This material was characterized as brown,yellowish-brown,reddish- brown,or tan-brown sandy gravel or gravelly sand with clay,with interbedded sandy clay,and slightly moist to moist where above groundwater.Sections of cobble-and boulder-sized river rock (mainly crystalline)in a clay,silt and sand matrix were encountered in TH-1 and TH-2,and comprised the base of the riverine gravel deposits,directly overlying the top of bedrock.Cobble and boulder sections were also encountered in TH-7 below the fill and at intervals in TH-8.TH-lO,and TH-ll.These deposits also likely include colluvium,glacial outwash,and possible debris fan or mudflow deposits. Relatively thin,3-to 5-foot thick,organic-rich layers were encotmtered in TH-1 and TH-3 within the alluvial deposits at a depth of 20 feet in both.These layers were generally comprised of very dark brown silty clay with trace sand, subrounded pebbles,mica,rootlets,and pieces of bark.These fme-grained, organic-rich layers may represent low energy alluvial deposition,or perhaps a past ground surface.Given the age of the ernbankments and the absence of distress in their current state,we do not expect these thin organic layers to have a significant impact on retaining wall stability. Fine-grained deposit:TH-3 encountered a thick layer of wet,soft,clay to silty clay at around 30 to 59 feet depth.The section was interbedded with light brown to tan colored fine-grained sand layers and angular fragments of dark gray claystone and light gray sandstone (measurinl inch)were also noted.The presence of angular claystone and sandstone fragments suggests this section is comprised of colluvium or debris fan deposits,at least in part.This soft clayey layer was not encountered in TH-2 (located approximately 200 feet to the northwest)or TH-4 (located approximately 180 feet to the east). A definitive geologic explanation for this layer cannot be given at this time. With regard to deposition,the borings at this western end of the alignment are in locations affected by the Eagle River,Beaver Creek and the upper slopes of the valley.It is likely this layer is any combination of:(1)alluvium deposited in a low- energy environment,like backwater eddies or beaver ponds;(2)a debris fan deposit;(3)a mudflow deposit;or (4)infilling of a void created by dissolution of soluble minerals in the Eagle Valley Evaporite.Due to the number of locations in the Eagle-Vail area that have reported cases of collapsible soils in areas where the Eagle Valley Evaporite is present (White and Greenman,2008),the depth of the deposit below the current stream level,and the fact that the borings to either side of TH-3 did not encounter the soft,fine-grained deposit,sediment-infihling of a dissolution void may be a reasonable explanation. Project No.111014 Mr.Kent Kriehn November 30,201 1 Page 9 The condition is interesting from a geologic perspective,but given its depth. the fact that the existing highway embankment has performed well at this location, and the scope of proposed construction,we do not expect this condition to significantly impact retaining wall stability.Because this clay-rich layer is a possible infihl zone and collapse-prone evaporite deposits may be present,some settlement could be experienced along the trail alignment at this location. Bedrock:Bedrock was encountered in TH-l through TH-5 at depths ranging from 17 to 49 feet below the ground surface.An upper weathered section,ranging from around 3-to 14-feet thick and comprised of claystone,siltstone and sandstone bedrock interbedded with clay,silt and sand,was encountered in TH-1,TH-2,TH 4,and TH-5.Relatively unweathered bedrock included claystone.siltstone and sandstone.Bedrock encountered is likely the Eagle Valley formation. Groundwater:The Eagle River is located nearby to the north of the trail alignment,thus shallow groundwater conditions can be expected at the site. Groundwater was encountered during drilling as indicated on the boring logs (Appendix 1).Groundwater was encountered in five of the nine test holes at depths varying from 20 to 40 feet beneath existing ground surface.The elevation of the groundwater encountered in these borings appears to be generally associated with the water level in the nearby Eagle River.The reader should note that these borings were drilled in late July or early August in a high runoff year —water in the river was still relatively high at the time of drilling.Groundwater levels can and do fluctuate with season,precipitation,runoff,and water levels in nearby bodies of water. 7M RETAINING WALL STABILITY AND RECOMMENDATIONS Slope stability analysis,including global stability of retaining walls is a means of assessing the relative stability of a slope and increases our understanding of the factors that contribute to stability or instability of a slope.All stability analyses require certain basic data that must either be gathered in the field or be assumed by the analyst.These data include:(1)a topographic cross section (study section)representative of the subject slope;(2)material properties including the shear strength of representative soil and bedrock materials (typically stated in tenns of cohesion and angle of internal friction);(3)depth to the phreatic surface and fluctuations of that surface with time,and;(4)geometry of the failure surface or assumption of a standard geometry (i.e.circular or non-circular).A prudent and meaningful slope stability model must consider all of these factors and the uncertainties inherent in each. for our analysis we used UTEXAS4,a two-dimensional limit equilibrium modeling software developed at the University of Texas.We used soil index property data from our lab testing,along with our experience in the area,to Project No.111014 Mr.Kent Kriehn November 30,2011 Page 10 estimate soil and bedrock (as applicable)strength properties for analysis.We developed subsurface geometry from test borings,published mapping,and interpretive input based on our understanding of site geologic conditions. Regarding the alluvial material,we did not model the cobble and boulder layers encottntered in a number of the borings.These layers are by nature discontinuous and likely form lenses rather layers.It is a conservative approach to exclude the cobble and boulders,which generally have higher shear strength than the finer grained soils.We used circular failure surfaces for these analyses. A total of 4 cross-sections were selected for analysis,as indicated on figures 1 and 2.Representative locations along the trail alignment where the proposed wall was highest andlor had high or steep slopes were used as the most critical cross-sections for analysis.The representative cross-sections can be applied to other locations along the wall with similar geometries.Characteristics of the cross-sections are summarized as follows: .Height of Wall Height of Slope Approximate SlopeCross-section (ft)(ft)Angle (H:V) A-A’8.4 10 2.4:1 B-B’10.0 14 2:1 C-C 7.9 27 1.5:1 D-D’14.9 26.2 1.5:1 First,stability of each cross-section was checked for the existing slope geometry.We regard this check as an important calibration of the analysis;since we know that the slopes in question have performed well,a factor of safety (F S) above 1.0 is implied for the existing condition.Where appropriate,we used this exercise to adjust (calibrate)the analyses to produce realistic factors of safety for the existing condition.‘With parameters for each section thus established,we checked the factor of safety for global stability of the proposed retaining walls with reinforcement lengths set to the minimums specified by SP 504.An acceptable factor of safety for the proposed retaining walls is a 1.3,or a factor of safety at or above the current condition.If inadequate factors of safety were determined,the reinforcement length was increased until an adequate factor of safety was calculated.We included a surcharge of 150 psf in our analyses for the bike trail and 250 psf for Highway 6.Using UTEXAS4 we calculated the surcharge of the Eagle River at the low and high water lines,where applicable.The results of these analyses are summarized as follows: ProjectNo.111014 Mr.Kent Krielrn November 30,2011 Page Il Minimum Cross-section FS Existing FS Proposed Reinforcement Length ______________ (ft) A-A’2.118 2.147 8 B-B’1.714 1.693 8 C-C’1.143 1.346 8 [D-D’1.101 See below N/A These analyses indicate that reinforcement length minimums as outlined in SP 504 are applicable for the proposed retaining walls for Cross sections A-A’,B- B’,and C-C”. Cross section D-D’is a “Double Wall”condition as described above and in our October 18 report.At cross-section D-D’the proposed retaining wall is 15 feet high (exposed)and is located in front of and downhill of an existing retaining wall for Highway 6.There is also a relatively high,steep slope down to the river at this location.Initial work on Cross Section D-D indicated that the “Double Wall” sections were problematic for global stability,but more critically,problematic for construction.Excavation for a conventional MSE wall at Section D-D’would severely undermine the existing Highway 6 retaining wall. Initial work on Section D-D’identified the need for our report dated October 18,2011 as cited herein.In that report,we recommended a micropile supported block face wall with lightweight fill for these sections.This approach should address both the global stability as well as constructability concerns for Section D-D’since: •The weight of the block face is supported on deep micropiles,so that weight will not decrease global stability, •The lightweight fill proposed has a unit weight of about 2 pounds per cubic foot,and its weight would be insignificant for global stability. •While not specifically designed to increase global stability,the proposed micropiles would be expected to enhance,rather than decrease global stability,and •Excavation is reduced or eliminated,so the new construction should not destabilize the existing wall. The reader may note that our analysis of the existing stability at D-D’ indicates a relatively low Factor of Safety,about 1.1.However,the wall and slope at this and similar locations appear to be performing well,and as long as construction does not add load or destabilize the wall,we believe the construction can proceed as described above and in our October 18 report. F or the remaining retaining walls in Phases 1 and 2 (i.e.,those not in “Double Wall”areas),the MSE wall minimum reinforcement lengths identified in Project No.111014 Mr.Kent Kriehn November 30,2011 Page 12 SP 504 are appropriate.In addition to these reinforcement lengths,we recommend that footings for the MSE wall facing (also known as “leveling pads”)be constructed at the depths specified in 5?504.We have provided a recommended footing layout to Alpine under separate cover.Because of the steep existing slopes downhill of these retaining walls,it is imperative that the footing layout provided on the plans be followed by contractors. SP 504 typically requires a concrete leveling pad,as well as protection of the MSE fill mass by a geornembrane.Based on our experience with similar applications in this area,we recommend that these requirements be changed for Phases 1 and 2 through a “Project Special Provision.”We recommend that the Project Special Provision allow: •Substitution of a granular leveling pad (Typically CDOT Class 6 Road Base)for a concrete leveling pad,and •Elimination of geomembrane for block faced MSE wall systems using polymer geogrids as MSE reinforcement elements. We should review all contractor shop drawings for compliance with SP 504 and applicable Project Special Provisions,as well as for consistency with the analyses we describe above. 8.0 BRIDGE FOUNDATION RECOMMENDATIONS Analysis and recommendations related to the proposed bridge structures located over the Eagle River and Beaver Creek will be presented in a future report.

changes,additions,or deletions shall be made to the Bid Specifications and Construction Plan Set as indicated,and all other conditions shall remain the same. 1.Revised Construction Agreement and General Conditions. The Eagle County Attorney’s office has revised the bid documents to reflect certain revisions,including but not limited to,identification of a representative for the Contractor in Article 2,a place for the Contract Price in Article 4 and changes in the state statute which now require progress payments up to 95%of the Work in Article 5.The General Conditions represent the ‘long form”and include a two year warranty period and more involvement from an Engineer representing the Owner. Please discard the previous Agreement and General Conditions in the Bid Documents and substitute the attached revised Construction Agreement (9 pages)and revised General Conditions (29 pages). 2.Questions on the Revised Construction Agreement and General Conditions. All questions on the meaning and intent of the attached Construction Agreement and General Conditions shall be submitted to ECO Trails in writing to the physical address or mailing address for ECO Trails as listed in the bid documents or emailed to ecarv1’ealecount\.us by Monday,February 6 at 9:00 a.m. Replies will be issued in writing by Addenda delivered to all parties recorded by ECO Trails as having received the Bid Documents,and in accordance with Section 5.2 Instructions to Bidders. ttIc... ADDENDUM #2 AVON TO EAGLE VAIL TRAIL PHASE II Bidders shall acknowledge receipt of this Addendum #2 on the Bid Form.Failure to do so may render the Bidder’s bid non-responsive.The following changes,additions,or deletions shall be made to the Bid Specifications and Construction Plan Set as indicated,and all other conditions shall remain the same. What is density of geofoam? The lightweight backfill is specified in revision of section 504,micropile supported concrete block wall with lightweight fill.3.Materials.EPS 15 (ASTM D681 7)with a minimum density of 0.90 lb/cubic foot. Is micropile wall a complete design builds including railing? It is a complete design and build wall system including,railing foundation but not the railing. Railing is per detail on the plans. Can wall batter be greater than 5%? Yes,if it does not significantly change wall height and design intent.I would anticipate this would result in lowering the leveling pad,thus making the wall incrementally taller.It will not result in an increase in pay quantity.To the extent this change makes the wall taller,it will affect geogrid length,excavation,and backfill quantity,none of which will result in any additional compensation from the plan quantity.If a contractor elects to implement such a system,he should consider the increased height in his design and quantities. Is one freeze thaw test for the MSE walls adequate across the whole job? Yes,one freeze thaw test on a project specific block sample will be acceptable (504.12). Does a technical representative for the geo-grid need to be present at the test wall,per 504.17? As long as the wall system supplier is qualified and able to serve as a technical representative for all furnished components of the system,then a separate representative of the geogrid supplier is not necessary. Which engineer must be present for required wall testing per 504.16? The technical representative of the wall supplier (see above)and a representative of the Owners Engineer. What is included in the micropile and block wall bid item? All elements of the wall system including all design,materials,railing foundation,testing, equipment,and incidentals to furnish and install Micropile supported concrete block wall with light weight fill.Excludes the pavement section (gravel and concrete)and the rail,which are separate pay items. Will top of railing step to match changes in wall height or “flow”,i.e.level top of railing? Top of railing to be level i.e.parallel to trail.Bottom tail measurement to trail platform can deviate as necessary to accommodate wall steps e.g.less or more gap than specified on detail. Are shoring locations identified? No,that is to be determined by the contractor’s design,means and techniques and soil conditions. Suggest temporary shoring be listed as a separate line item to guarantee that shoring occur. Additional cross sections will be provided so contractor can determine extent of shoring required which he is to include in the cost of the wall. Can cross sections be provided at less than 100 foot intervals in the wall area?Additional cross sections will be provided. What is concrete wedge shown on Detail #8,pg.37? I believe that is the approach slab for the traffic barrier. Where are access points into project? East side at bridge,generally at mid-point of golf course and other accesses as may be approved by CDOT and incorporated into the contractor’s traffic control plan. Is geomembrane required to protect from solvent or in any case? No Clarify why plans don’t show a geomembrane but Section 504 does reference geomembrane in several locations. A geomembrane is not required to protect the EPS geofoam from solvent.However,a geotextile to prevent migration of soil particles into the geofoam mass is required as shown on the plans. What level of damage to foam will result in rejection for use?Define damage. Damage to Foam shall be corrected as follows:Slight damage (<0.12 cubic feet with no linear dimension >1 ft)may be left in place as-is.Moderate damage (<0.35 cubic feet with no linear dimension >3.3 ft)shall be trimmed in field and damaged Foam portion of block shall not be used. Foam blocks with excessive damage (i.e.,exceeding the “moderate”category)shall be replaced with Foam blocks,which meet the damage criteria.Foam blocks not meeting the damage criteria may be cut to eliminate the excessive damage and the remaining undamaged portion of the block may be used within the fill,provided the undamaged portion of the block meets all other requirements. Clarify what “adequate training”refers to in regards to experience in micro pile wall construction. We understand this question to be related to Section 4.2 of the Micropile supported wall revision. ‘Adequate training”refers to the qualifications of the.micropile contractor’s foreman.Please submit a resume for the foreman documenting his/her experience and training,with emphasis on experience with micropile installation.The Owner will not accept an inexperienced foreman.If the proposed foreman has received training specific to micropiles (apart from experience),include this in the resume. 2 Clarify if Traffic Control Supervisor needs to be on site every day from 6:30 to 7:00. During all work within paved road shoulder or traffic lane,Traffic Control Supervisor needs to be on site while work is in progress. Clarify that no flagging hours will be provided with Bid Form. Contractor to estimate flagging needs.All traffic control is contained in a single lump sum item. Will we be allowed to set jersey barriers for the length of the project and utilize the far west bound lane of Highway 6 as a permanent construction zone for the duration of the project? See previous answers regarding traffic control. Will you consider breaking out the flagger hours necessary for the job and the TCS hours necessary like CDOT does in their bids rather than lump sum all traffic control? Contractor needs to consider methods and anticipated needs for traffic control.Traffic control will be lump sum bid item. Is one freeze thaw test adequate for total sf on the bid tab, Yes (see above). Per 504.17,does a tech rep from the geo-grid need to be on site for the test wall. See above -As long as the wall system supplier is qualified and able to serve as a technical representative for all furnished components of the system,then a separate representative of the geogrid supplier is not necessary. Please confirm that both the colored and grey quantities of 6”concrete are included in item #608-00006.Also please provide a color spec for the Dark Grey (DA VIS COLOR).608-0006, Concrete Trail and Sidewalk (6’9,Sheet 37,Detail #6. Bid Form has been revised to include colored concrete line item.Preferred color is Dark Gray /860/Iron Oxide. Please confirm that the overall width of the trench drain is only 8 inches.603-19708,Inlet Special (Trench Drain),8”width. 8”is correct. Please provide a more detailed drawing of the Cantilevered design for the Type 7 Barrier on top of the MSE wall including rebar and permissible construction joints,dimensions etc. 606-00705,Guardrail Type 7,(Special),CIP Traffic Barrier on MSE Wall,Sheet 37,Detail #8. The design of the traffic barrier is per the contractor and needs to function with the wall system design.A general drawing a traffic barrier is available on the keystone wall web site and is attached.The trail plans specify a 42”height above the trail and the Keystone detail is only 32”. For the pedestrian railing,can the horizontal 2x2 tubes be welded to the face of the vertical posts?This would help keep the horizontal rails matching the contour of the path. Horizontal tubes should be welded per plan detail.Adjustments to bottom rail would be allowed,to help match the contour of the path. Is the existing Type 7 Barrier is colored if so,what is the color specification Proposed traffic barriers do not require concrete coloring 3 Have any utility conflicts been identified with the Guardrail at the Post Blvd intersection that would require guardrail posts to be hand dug and placed?I remember some issues with the installation of the original guardrail in that area.I just cannot remember if they were further to the East.I believe that it was a Concrete encased fiber optic line. It is not known if there are any conflicts.It appears some of Centurylink’s lines are in proximity. See attached input that has been provided from utility companies. Quantity of temporary shoring required.Will this become a new line or bid item and if so what will be the square foot quantity? The quantity of temporary shoring required depends on the contractors means and methods and the soils.Additional cross sections are being provided to illustrate the relationship of the leveling pad and the highway.Temporary shoring will not be a separate pay item but is included in the cost of the work. Are you going to require a specific/special fuel impervious membrane over the geo-foam. No Re:MSE Retaining Wall/the revision of Section 504 Concrete Block facing contains elements that are standard to a typical CDOT MSE Retaining Wall construction.However, several of these details are not incorporated into the standard cross sections shown on sheet 37 of the plans.Please clarify whether the following elements detailed in the Revision Section 504 will be required? The wall sections shown on the plans are general in nature and not intended to capture all elements of the wall.Wall should be designed per the revisions to section 504. Re:MSE Retaining Wall.Will the top 2 courses of wall require grouting and rebar reinforcement under precast capstone sections? The contractor’s design should include elements to secure the upper two courses in place,and discourage vandalism,where the top of the wall is exposed.Such measures are not required where a concrete barrier protects the top of the wall.Rebar is not required unless some other aspect of the contractor’s design requires it. Re:MSE Retaining Wall.Will a “Heel drain”be required along the face of the excavation?And will construction as detailed on Sheet 5,504.10,Second Paragraph,of the Revision of Section 504 be required. A “heel drain”is not required for the conventional MSE walls.Note also that that 504.10 has been revised to delete the geomembrane requirement except for block faced MSE walls with metallic reinforcement.A heel drain is required on the Micropile supported walls. Re:MSE Retaining Wall.Has the Ultimate Bearing Capacity of the foundation soils under the MSE Block facing walls been determined?If so,what is it? Yes.The Owner’s engineer has checked this issue as well as global stability for the conventional MSE walls.Contractors are not required to address bearing capacity and global stability. 4 Re:Micro Pile and Lightweight fill Retaining Walls.Are the piles for global stability of both walls or for face load on the new block wall?This will help us quantify the loads and pile lengths. The contractor should design the micropiles based on the lace load of the new block wall,including any lateral loads that may be induced by dead loads (pavement and base)or traffic loads such as snow removal equipment. Re:Micro Pile and Lightweight fill Retaining Walls.Can we sit on the highway and stop one lane or does all construction have to occur below the road? Contractors will be required to obtain permission from CDOT to potentially work or access from the highway and a detailed contractor prepared traffic control plan will have to be submitted and approved by CDOT. Re:Micro Pile and Lightweight fill Retaining Walls.Will a Vertical Slip Joint be required between MSE Retaining Walls and the Micro Pile Supported walls with Lightweight fill? Probably.However,design details are to be determined by the contractor.The owner recommends inclusion of a vertical control joint at this interface. The geotech report references an October 18 report which recommends the micropilelfoam design.Can you please send me a copy of that report. The October 18 report was the geotechnical memo to CDOT outlining the field conditions and existing highway walls and potential solutions including the micropile wall.CDOT has approved the micropile wall solution and the bid documents require that wall type. Additional Project Information: Contractor Staging Areas are available on CDOT property underneath 1-70 bridges and in fenced yard at Southeast Corner of 1-70 Eagle Vail Exit and Highway 6.Ingress/Egress for staging areas to be included in Traffic Control Plan. Bid Submittal requires Micropile qualifications per Section 3 of the Instructions to Bidders.
