Agenda Item
Resolution - Engineering:
Consider a resolution authorizing the Mayor to execute Amendment No. 1 to Contract 14966, with Garver, LLC, for North Water Treatment Plant ground storage construction phase services.
Item Summary
The North Water Treatment Plant (NWTP) currently has a ground storage tank which supplies Pump Station 11 with distribution water. This ground storage tank is vital to operations of the NWTP. During a freeze event in 2018, the air vent to the tank froze shut, causing air to become entrapped within the tank while it was being filled with water. This caused the tank to over-pressurize, which resulted in beams separating from the roof structure and support columns shifting inside the tank by over two feet. The existing ground storage tank currently continues to be in operation, but has severe structural damage and must be replaced.
Garver, LLC was awarded Contract 14966 to design the replacement tank. Staff conducted contract negotiations with Garver, LLC, and fair and reasonable hourly rates were agreed upon for a contract amendment amount not to exceed $194,342 and an additional 515 days. This amendment will provide Construction Phase Professional Engineering Services, including Engineer of Record (EOR) and Resident Project Representative (RPR) services.
Fiscal Impact
This cost of the contract amendment is not to exceed $194,342, and is funded in Capital Improvements Project 92660, NWTP 8 MG Ground Storage Tank.
