Title
Resolution Waiving the Formal Written Bidding Requirement on the Basis of Sole Source and Emergency and Approving a Construction Contract with Garney Companies Inc. for the Ray Waterman Regional Water Treatment Center and the Bell Mountain Ranch LAS Conversion Project [Ray Waterman Regional Water Treatment Center and Bell Mountain Ranch Water Treatment Plant]
Body
________________________________________________________________________________
Executive Summary
Castle Rock Water (CRW) staff requests approval of a Resolution approving a sole source Construction Contract and Work Package 1 under that contract (Attachment A) with Garney Companies (Garney) to complete construction of liquid ammonium sulfate (LAS) chemical conversion projects at the Ray Waterman Regional Water Treatment Center (RWRWTC) and the Bell Mountain Ranch Water Treatment Plant (BMR). This project will be completed in two work packages. Work Package 1 is for $1,199,662 and will be executed to allow for procurement of long lead equipment. Work Package 2 will be for the remainder of the work. Final pricing is still being developed for Work Package 2.
Now that the WISE project is ramping up to full deliveries and CRW is also delivering Dominion’s WISE and other water supplies, it is critical that CRW be able to bring WISE water directly into our system, bypassing retreatment at RWRWTC which currently cannot be done. Retreatment at RWRWTC means that we are limited to the total treatment capacity of the plant and WISE water and other supplies do not add to our overall water suppl capacity. This project is necessary to ensure that bringing WISE and other imported supplies directly into our system is possible. This will increase the overall water supply capacity of CRW, which is important to keep up with growth. It will also ensure that we do not run into a situation where WISE water is being offered and CRW cannot accept that water (known as take-or-pay). If this case were to occur, CRW would be at risk of paying hundreds of thousands of dollars per month and not receiving the benefit of the water supply.
Budget Impact
Garney’s proposal for Work Package 1 is $1,199,662. Staff requests an additional $119,966 (Town-managed 10% contingency) be authorized for a total project authorization of $1,319,628. The project will be funded from the accounts shown in the table below. There is $1,930,372 remaining in the budget for Work Package 2.
