Title
Resolution Approving the First Amendment to the Town of Castle Rock Services Agreement with Jacobs Engineering Group Inc., for the Crystal Valley Interchange Project
Body
________________________________________________________________________________
Executive Summary
The purpose of this memo is to obtain Town Council approval of an amendment to the Service Agreement between the Town and Jacobs Engineering Group (Jacobs) for design services on the Crystal Valley Interchange (CVI) Project.
The attached resolution (Attachment A) approves the amendment to the service agreement with Jacobs which allows Jacobs to remain under contract to complete the design for CVI. This amendment is a time adjustment only.
Discussion
Under the current contract, supplementary design effort will be required to complete the CVI design. The known design changes can be categorized as follows:
• Accommodate the design change for the NB onramps to a single merge from the original planned double merge to I-25 as required by FHWA comments
• Development of an Executive Summary Memo requested by CDOT to accompany the Environmental Assessment Reevaluations
• Supplemental coordination for the additional Traffic Demand Management requirements of CDOT’s 1601
• Additional coordination with US Army Corps of Engineers (USACE) and EPA on 404 permit and process
• Additional coordination on the Water Quality Pond on the west side of I-25
With cost savings in other aspects of the design, there is no additional cost to the design service agreement. This amendment adds 176 days to the contract, and sets a new completion deadline of November 30, 2023. There is no change to the planned construction schedule associated with this amendment.
