Consider a resolution authorizing the Mayor to execute Change Order No. 1 to the construction contract with Keystone Construction, Inc. for the Raw Water Delivery System - Pumps Improvement Project. Department: Water and Wastewater Utilities Staff Person: Michael Thane, Utility Director Justification: With approval of the construction contract with Keystone Construction, Inc. for $4,218,317.14 to increase the raw water delivery capacity from Lake Georgetown from 39 million gallons per day (mgd) to 48 mgd, Change Order No. 1 would increase the capacity to 52 mgd, which is the City's total capacity in Lake Stillhouse and Lake Georgetown. This Change Order is in the amount of $871,967.18 or 20.67% of the original contract amount. Approval of the change order will give the City an additional 4 mgd of raw water capacity for about 22 cents per gallon. Therefore, staff agrees with the Design Engineer's recommendation to approve Change Order No. 1. Funding: Cost: $871,967.18 Source of funds: Capital Project Funds (Self -Financed Utility) Outside Resources: Keystone Construction, Inc. Camp Dresser &McKee (CDM) Background Information: The City Water Treatment Plant (WTP) was expanded to a capacity of 48 mgd with the completion of the Phase V plant expansion. The City is in the process of getting approval from TCEQ to re -rate the WTP to 52 mgd. Therefore, because of the re -rating of the plant, the City asked the Design Engineering, (CDM), to negotiate with Keystone the cost to the City to increase the capacity to 52 mgd. The result of these negotiations is the reasonable cost of Change Order No. 1. A subsequent project for the Raw Water Delivery System - Line Improvements is under design to construct about 20,000 linear feet of 54 -inch raw water line that will be bid in the Spring of 2007 provided we have acquired all the required easements. This would complete the improvements required to deliver 52 mgd of raw water to the WTP from Lake Georgetown and Lake Stillhouse.
