ENGINEER’S review and approval shall be only for conformance with the design concept of the Project,and
for compliance with the information given in the Contract Documents,and shall not extend to means,methods,
sequences,techniques,or procedures of construction,or to safety precautions of programs incident thereto.
The review and approval of a separate item as such will not indicate approval of the assembly in which the
item functions.CONTRACTOR shall make any corrections required by ENGINEER,and shall return the
required number of corrected copies of shop drawings,and resubmit new samples for review and approval.
CONTRACTOR shall direct specific attention in writing to revisions other than the corrections called for by
ENGINEER on previous submittals.CONTRACTOR’S stamp of approval on any shop drawing or sample
shall constitute a representation to OWNER and ENGINEER that CONTRACTOR has either determined and
verified all quantities,dimensions,field construction criteria,materials catalog numbers,and similar data,or
12
assumes full responsibility for doing so,and that CONTRACTOR has reviewed or coordinated each shop
drawing or sample with the requirements of the Work and the Contract Documents.
6.28 Where a shop drawing or sample is required by the specifications,no related Work shall be commenced until
the submittal has been reviewed and approved by ENGINEER.
6.29 ENGINEERS review and approval of shop drawings or samples shall not relieve CONTRACTOR from
responsibility for any deviations from the Contract Documents unless CONTRACTOR has,in writing,called
ENGINEERS attention to such deviation at the time of submission,and ENGINEER has given written
concurrence and approval to the specific deviation,nor shall any concurrence or approval by ENGINEER
relive CONTRACTOR from responsibility for errors or omissions in the shop drawings.
CONTINUING THE WORK:
6.30 CONTRACTOR shall carry on the Work and maintain the progress schedule during all disputes or
disagreements with OWNER.No Work shall be delayed or postponed pending resolution of any disputes or
disagreements,except as CONTRACTOR and OWNER may otherwise agree in writing.

6.31 To the fullest extent permitted by law,CONTRACTOR shall indemnify and hold harmless OWNER and
ENGINEER,and their officials,agents and employees,from and against all claims,damages,liabilities,
losses,and expenses including,but not limited to,attorney’s fees arising out of,or resulting from,the
performance of the Work,provided that any such claim,damage,liability,loss,or expense is attributable to
bodily injury,sickness,disease,or death,or to injury to or destruction of tangible property including the loss
of use resulting therefrom or is caused,in whole or in part,by any negligent act or omission of
CONTRACTOR,any Subcontractor,anyone directly or indirectly employed by any of them,or anyone for
whose acts any of them may be liable,regardless of whether or not it is caused in part by a party indemnified
hereunder.Nothing in the contract shall be interpreted that the OWNER waives its sovereign immunity
granted under Colorado Governmental Immunity Act or other applicable law.
6.32 In any and all claims against OWNER or ENGINEER,or any of their agents or employees,by any employee
of CONTRACTOR,any Subcontractor,anyone directly or indirectly employed by any of them,or anyone for
whose acts any of them may be liable,the indemnification obligation under paragraph 6.31 shall not be limited
in any way by any limitation on the amount or type of damages,compensation,or benefits payable by or for
CONTRACTOR or any Subcontractor under worker’s or workmen’s compensation acts,disability benefit acts,
or other employee benefit acts.
6.33 The obligations of CONTRACTOR under paragraph 6.31 shall not extend to the liability of ENGINEER,his
agents,or employees arising out of the preparation or approval of maps,drawings,opinions,reports,surveys,
change orders,designs,or specifications.

execution of work,and shall properly connect and coordinate his work with theirs.
13
7.2 If any part of CONTRACTOR’S Work depends,for proper execution or results,upon the Work of any such
other contractor or utility service company (or OWNER),CONTRACTOR shall inspect and promptly report
to ENGINEER in writing any patent or apparent defects or deficiencies in such Work that render it unsuitable
for such proper execution and results CONTRACTOR’S failure to so report shall constitute an acceptance of
the other Work as fit and proper for integration with CONTRACTOR’S Work,except for latent or nonapparent
defects and deficiencies in the other Work.
7.3 CONTRACTOR shall do all cutting,fitting,and patching of his Work that may be required to make its several

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

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.

11.8 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

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

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.
PARTIAL UTILIZATION:
14.10 Use by OWNER of completed portions of the Work may be accomplished prior to substantial completion of
all the Work subject to the following:
14.10.1 OWNER,at any time,may request CONTRACTOR in writing to permit OWNER to use any part of
the Work which OWNER believes to be substantially complete and which may be so used without
significant interference with construction of the other parts of the Work.If CONTRACTOR agrees,
CONTRACTOR will certify to OWNER and ENGINEER that said part of the Work is substantially
24
complete,and request ENGINEER to issue a certificate of substantial completion for that part of the
Work.Within a reasonable time thereafter,OWNER,CONTRACTOR,and ENGINEER shall make
an inspection of that part of the Work to determine its status of completion.If ENGINEER considers
that part of the Work to be substantially complete,ENGINEER will execute,and deliver to OVTNER
and CONTRACTOR,a certificate to that effect,fixing the date of substantial completion as to that
part of the Work,attaching thereto a tentative list of items to be completed or corrected before final
payment.Prior to issuing a certificate of substantial completion as to part of the Work,ENGINEER
will deliver to OWNER and CONTRACTOR a written recommendation as to the division of
responsibilities pending final payment between OWNER and CONTRACTOR with respect to
security,operation,safety,maintenance,utilities,and insurance for that part of the Work which shall
become binding upon OWNER and CONTRACTOR at the time of issuing the definitive certificate of
substantial completion as to that part of the Work,unless OWNER and CONTRACTOR shall have
otherwise agreed in writing.OWNER shall have the right to exclude CONTRACTOR from any part
of the Work which ENGINEER has so certified to be substantially complete,but OWNER shall allow
CONTRACTOR reasonable access to complete or correct items on the tentative list.
14.10.2 In lieu of the issuance of a certificate of substantial completion as to part of the work,OWNER may
take over operation of a facility constituting part of the Work,whether or not it is substantially
complete,if such facility is functionally and separately usable provided that prior to any such
takeover.OWNER and CONTRACTOR have agreed as to the division of responsibilities between
OWNER and CONTRACTOR for security,operation,safety.maintenance,correction period,heat,
utilities,and insurance with respect to such facility.
14.10.3 No occupancy of part of the Work,or taking over of operations of a facility will be accomplished
before the insurers providing the property insurance have acknowledged notice thereof and in writing
effected any changes in coverage necessitated thereby.The insurers providing the property insurance
shall consent by endorsement on the policy or policies,but the property insurance shall not be
cancelled or permitted to lapse on account of any such partial use or occupancy.
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.

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.
(2)No more than 50 percent fine aggregate (AASHTO M6)by volume of total
aggregate.
(3)Ambient temperature shall be a minimum of 400 F and rising when casting.
(4)Hybrid MSE wall facing shall be cured in accordance with AASHTO Ml 70.
The following Certifications,Calculations and Testing Reports in subsection 504.12(c),
(e),(g),and (h)are not required for Hybrid MSE wall systems.The facing to soil
reinforcement connection test,subsection 504.12(b),may be waived only if the soil
reinforcing spacing is less than or equal to 8 inches or the facing is secured and stabilized
by hybrid components with primary reinforcement spacing less than 24 inches.The
Contractor shall provide the following additional reports,certifications and calculations

The concrete block shall have cells to accommodate grouted pins and modifications shall
be made for blocks that do not have such cells.Grout is limited to penetrate a maximum
depth of three blocks measured from the top of fill for each operation.for grout more
than three blocks in height,if specified on the plans,multiple grout operations are
required.A layer of fabric shall retain the grout in the lowest grouted block layer.The
aggregate for grout shall be modified according to cell size and geogrid aperture.Grout
in any 20 foot long wall segment shall be placed and consolidated by a minimum of two
simultaneously working concrete vibrators.Precast cap blocks shall not be used in lieu
of a cast-in-place reinforced concrete cap.All concrete used for cast-in-place cap and

wall shall be redesigned with longer reinforcement length and revised reinforcement
schedule.
METHOD OF MEASUREMENT
504.25 MSE retaining walls will not be measured for payment in the field,but will be
paid for by the calculated quantities shown on the plans for the five major components of
the wall:structure excavation,structure backfill,block facing,mechanical reinforcement
of soil,and geomembrane.The Contractors construction of a system that requires
increased or decreased quantities of any of the components to complete the wall to the
dimensions shown will not result in a change in pay quantities.Exceptions will be made
when field changes are ordered or when it is determined that there are discrepancies on
the plans in an amount of at least plus or minus five percent of the plan quantity.
(1)The block facing quantity was calculated for the square foot of wall front face area
from the top of the leveling pad (or average pad elevations)as shown on the plans to
the top of the anchoring slab for walls with railing,or to the top of the cast in place
coping for walls without railing.
(2)The structure excavation quantity was calculated for the total volume of earth to be
removed before the installation of the reinforced zone as shown on the plans.
(3)The structure backfill quantity was calculated for the total volume behind the wall
(the retained structure backfill zone)including the material in the reinforced zone as
shown on the plans.
(4)The mechanical reinforcement of soil quantity was calculated for the total volume of
the reinforced zone as shown on the plans.
(5)Geomembrane was calculated as the design height (DH)plus soil reinforcement
length (RL)plus 1 .5 feet,disregarding the slope of the membrane.

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

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

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.

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

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.

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

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

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:

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.

LATE FALL,WiNTER AND SPRiNG SPC1AL
PROVISIONS FOR WORK WITWN CDOT ROW
It’s that time of year again when work within the Right of Way (ROW)
becomes a special concern.Dite to Northwest Colorado’s unpredictable
weather,work in the ROW can create severa’types of hazards for the traveling
public,contractors,and their personnel.The condition of the highway can
change quickly.Mud tracked onto the highway by equipment,or ice and
snowpack are just a few of the conditions that make the roadway more
hazardotts for all concerned.The terrain within the ROW must be kept clear of
hazards as well.I loles,trenches,equipment and materials can make the terrain
“unrecoverable”for a driver should his/her vehicle leave the highway.
Activities must be shut down when the roadway is other than dry,The use
of frozen materials for backfilling will only lead to settlement.The contractor
must make extra effort to compact the excavation.In the spring,any settlement
of backfill shall be repaired.The re-vegetation shall take place yet this fall or
early next spring.

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.
