AGENDA CAPTION:

Consider Action to Approve a Resolution for a Professional Services Agreement with Garver, LLC, for the Design Services for Surveyor Pump Station Pump #1 Replacement and Authorize the City Manager to Execute the Agreement in an Amount not to Exceed $16,408.

BACKGROUND:

The Town of Addison owns and operates two potable water pumping stations, Celestial Pump Station and Surveyor Pump Station. The Surveyor Pump Station is located on the northeast corner of Arapaho Road and Surveyor Blvd. The pump station was built in the 1970s and serves as one of the two water supply entry points from Dallas Water Utilities. The facility includes a two million gallon ground storage tank and associated pumps and appurtenances.

The Surveyor Pump Station houses three, 4,000 gallons per minute pumps and 250 horsepower motors that move water from the ground storage tank to the Surveyor Elevator Storage tank across Arapaho Road. It is then distributed to the system for use by the customer.

Surveyor Pump #1 has been in place since the facility was constructed. The typical life for pumps and motors of this type is 30 years. Therefore, Pump #1 has exceeded its expected life and needs to be replaced.

Garver will provide design and bid phase services for the replacement of Pump #1. The scope of work includes:

Preparation of construction plans and specifications
Coordination with various pump manufacturers
Development of specific pump clearance and specification requirements
Preparation of an opinion of probably construction cost
Assistance during the bid phase with bid package preparation and assessment of bids that are received

Garver was selected by a Request for Qualifications (RFQ) that the Town issued in late 2017. They are very experienced with these types of projects and come very highly recommended. A design contract of this amount would not normally need Council approval however, Garver is also designing the needed electrical improvements at the Kellway Lift Station for a contract amount of $46,827. According to the Town's purchasing policy, adding this additional contract value to the work that Garver has already been contracted to perform, pushes the amount above $50,000, thereby requiring Council approval.

Funds for the design and construction of the pump replacement are allocated in the Utility Capital Projects fund in the amount of $181,000. Design is expected to take 45 days to complete and then the project will go out for bid.

RECOMMENDATION:

Administration recommends approval.
