Memorandum
This memorandum and resolution requests approval of Change Order No. 5 with Weiss Construction Co. LLC, for the Barton Pump Station Valve Improvement Project ($590,960.00 Increase, Total Contract Amount $5,637,998.50). Attached for your review and approval is a change order to the construction contract with Weiss Construction Co. LLC, (ITB 4703) for the Barton Pump Station Valve Improvement Project.
The scope for this project includes replacement of aging and inoperable valves and the associated piping at Barton Pump Station and installing new air release valves on the existing 42-inch and 24-inch raw water transmission mains. The improvements are necessary to assure operational control and system reliability for the City’s critical raw source water supply infrastructure.
The additional contract work includes additions to the scope of existing piping to be replaced and the addition of temporary linestops to provide isolation due to unforeseen conditions at the pump station including inoperable valves and deteriorated pipe conditions. The total change order amount is $590,960.00, which exceeds the balance of the contingency originally approved by Council ($470,000.00) This Change Order will bring the total contract amount to $5,637,998.50. Due to the complexity of the work, City Staff is also recommending re-establishing a contingency of $330,000.00 for potential future change orders.
Budget/Fiscal Impact: Partial funding for this project is included in the approved Water Supply System Capital Budget. The balance is available in the Water Supply System Fund Balance. The project will be partially reimbursed through a Drinking Water Infrastructure (DWI) Grant in the amount of $1,380,000.00 and a Drinking Water Supply Revolving Fund (DWSRF) low interest loan in the amount of $3,220,000.00.
