ONE (1) AIRPORT Eagle County Regional Airport LOCATION Gypsum, Colorado JUSTIFICATION FOR CHANGE 1. Brief description of the proposed contract change( s) and location( s). Schedule II of the Grading and Drainage Project for the Runway 7/25 Extension project at the Eagle County Regional Airport, includes completing the placement of embankment required for the overall project, available from on-site borrow sources. Other construction items for this phase of the project include: Pavement Removal of the Existing Runway 25 Blast Pad, Drainage Infrastructure, Seeding and Erosion Control, and Removal of the Existing MALSR System. Since there will be work within the extended safety area of the Runway, a 1,000 foot temporary displacement of the Runway 25 threshold will be required to complete the project. This schedule of the project was originally bid on March 10, 2005, as "Schedule II, Alternate B". 2. Reason(s) for the change(s) (Continue on reverse ifnecessary) Based on the rapidly rising cost of construction throughout the entire region, it is in the best interest of both Eagle County and the FAA to award the "Schedule II, Alternate B" bid schedule of the original bid for the Grading and Drainage Project for the Runway 7/25 Extension, submitted by Kelley Trucking, Inc., dated March 10, 2005. Kelley Trucking, Inc. was the lowest bidder for "Schedule II, Alternate B", by a considerable margin. Their bid price of $2,567,705.00 was well under half of the bid price submitted by Ames Construction, Inc. of $5,935,000.00 and nearly $1,000,000.00 less than the original Engineer's Cost Estimate of $3,514,925.00. Based on construction costs seen throughout the region, there is little reason to believe that the cost to complete Schedule II of the project would be less than the negotiated cost with Kelley Trucking, Inc., as shown on the front page of this document. In addition, the Contractor has illustrated that they can complete the project in an adequate time frame and provides a quality product. 3. Justifications for unit prices or total cost. New unit costs were negotiated with Kelley Trucking, Inc. for items that were not included in the original bid proposal for "Schedule II, Alternate B", dated March 10,2005. The unit costs negotiated are favorable and consistent with historical data of Airport project pricing in the region. These item(s) include the following and the unit costs for these items are shown on the front page of this document: · Pl40a Remove Existing Blast Pad · P-152c Unclassified Excavation · P-620a Permanent Pavement Markings · P-620b Temporary Pavement Markings · P-620c Pavement Marking Obliteration (by Protectar) · P-620d Pavement Marking Obliteration (by Painting) · D-701d Install 18-InchRCP,Cl. V . D-751 b Tie Into Existing Manhole/Inlet · F-162a Install Temporary 8-Foot Chain Link Fence · L-400a Install Runway 25 Temporary Displaced Threshold & Reset to Original Configuration . CDOT-304a Class 6 Roadbase Page 4 of 4 pages The UnIt costs of items that were included under the original bid proposal for "Schedule II, Alternate B", dated March 10, 2005, are retained at the original unit costs. Item P-IOOa Mobilization increased from $300,000 to $390,000, predominately due to inflationary increases over the past 20 months. The overall mcrease for "Schedule II, Alternate B" amounts to approximately 3 .5%. 4. The Sponsor's share of this cost is available from: The Sponsor's share of the cost will be paid from Eagle County's general fund and/or airport fund. 5.
