Title
Resolution Approving a Services Agreement with Consor North America, Inc. for the Castlewood 1 Lift Station Upgrade Design Project
Body
________________________________________________________________________________
Executive Summary
The purpose of this memo is to request Council approval of a Resolution approving a Services Agreement (Attachment A) with Consor North America, Inc. (Consor) for design engineering and bid support services for upgrades to or replacement of the existing Castlewood 1 Lift Station (CW1). This lift station moves sewer flows from the Castlewood Ranch development area to Mitchell Creek Lift Station and ultimately to the gravity sewer system feeding into Plum Creek Water Reclamation Authority’s wastewater treatment plant. The lift station, which was installed in 2002, has a failing foundation and other aspects that are in need of full replacement or rehabilitation. An alternatives analysis will be performed to determine if an upgrade of the existing facility or a full replacement will be most cost effective over the life cycle of the facility. Staff recommends approval of the agreement between Castle Rock Water (CRW) and Consor for $393,993 with 10% Town managed contingency for a total authorization of $433,392.30. Services are expected to begin upon execution of the contract and be completed by October 2026.
Budget Impact
The Consor proposal fee is $393,993. Staff requests an additional $39,399.30 (Town-managed 10% contingency) be authorized for a total project authorization of $433,392.30. The project will be funded from the account shown below. A budget transfer will be completed to transfer $500,000.00 from Young American Rehab (213-4575-445.79-31) to the Lift Stations Upgrade Project Fund (213-4575.75-61).
