Body
BACKGROUND
The June 2019 Condition Assessment of Pump Stations, Ground Storage Reservoirs, and Elevated Tanks recommended the replacement of the Lake June Pump Station (PS), ground storage reservoir, and associated transmission piping. The report ranked Lake June PS as the most critical pump station of the Dallas Water Utilities’ (DWU) 14 potable water pump stations. Lake June PS has a firm capacity of 360 million gallons per day, was constructed in 1960, and is located at 1031 Algonquin Drive, Dallas TX 75217. It delivers potable water to three separate pressure planes in South Dallas and is the only source for the Cedardale Pressure Plane. The report noted much of the infrastructure is well beyond its useful life with significant structural defects. This project will include an entirely new pump station, new ground storage tanks, and transmission piping to replace the existing infrastructure.
This action will authorize a professional services contract with Garver, LLC for the Lake June Pump Station and Reservoir Replacement project to provide preliminary engineering, final design, bidding, construction phase services, and start-up services for the new Lake June PS, new ground storage tanks, transmission piping improvements, electrical improvements, and miscellaneous system improvements. Engineering services are intended to be executed through this initial professional services agreement followed by supplemental agreements as needed to complete the final design and construction improvements. The scope of services for the initial agreement includes preliminary engineering for the pump station and reservoir replacement.
Future supplemental agreements are anticipated to provide the final design, bidding, and construction services. Garver, LLC will evaluate alternatives for replacement of Lake June PS and reservoir and develop recommendations for improvements considering criticality, benefits, capital cost, and life cycle costs. They will identify temporary and permanent impacts to the system to define benefits, risks, and mitigation strategies. Garver’s approach to design and construction for this project involves separating the improvements into two construction packages. Construction Package A consists of the new ground storage tanks, transmission piping improvements, and demolition of the existing reservoir and ancillary facilities. Construction Package B consists of the new Lake June PS, suction and discharge piping, transmission piping as needed to connect the new Lake June PS into DWU’s distribution system, electrical improvements, system transmission improvements, and demolition of the existing Lake June PS and ancillary facilities.
The consulting firm for this project was selected following a qualifications-based selection process in accordance with City of Dallas Administrative Directive 4-05 procurement guidelines.
