Title
Resolution Approving a Second Amendment to the Services Agreement with Dewberry Engineers Inc., for the Young American Infrastructure Improvements, Bell Mountain Raw Pipeline, and Bell Mountain Flow Meter Vault Upgrade Projects [Young American neighborhood and Bell Mountain Ranch]
Body
________________________________________________________________________________
Executive Summary
Castle Rock Water (CRW) is seeking Town Council approval of a resolution approving a Second Amendment to the Service Agreement (Attachment A) with Dewberry Engineers, Inc. (Dewberry) for design of the Young American Infrastructure Improvements, Bell Mountain Raw Pipeline, and Bell Mountain Flow Meter Vault Upgrade Project. In an effort to reduce administrative and contracting costs, gain economies of scale and generate more competitive engineering bids, CRW staff initially combined three separate but smaller design projects into one request for proposals. Location maps of the three project areas are included in Attachments B and C.
The current authorization for this Service Agreement includes Dewberry's project cost for design in the amount of $623,784, with a contingency of $31,189, for a total authorization of $654,973. Previously, a first amendment to the service agreement was approved to add contract time only to continue with further development of the designs for each of the projects through December 31, 2024. Additional scope and fee is needed to complete the Young American Infrastructure Improvements design. The total added fee for Dewberry under Amendment 2 is $138,653. This project will encumber the remaining project contingency of $31,189 and staff requests approval of an additional $107,464 for a total revised authorization amount of $762,437 for Dewberry’s services. The scope of services to be completed by Dewberry is detailed in an attachment to the agreement (Exhibit 1). CRW staff have reviewed the scope and cost and believe the fee proposed by Dewberry to be reasonable.
Dewberry shall undertake the work upon execution of the agreement and shall complete the work by December 31, 2025.
The Dewberry proposal fee for Amendment 2 is $138,653. This project will encumber the remaining project contingency of $31,189. Staff requests approval of an additional $107,464 for a total contract amount of $762,437. The project will be funded from the remaining contingency in the accounts shown below:
