Title
Wastewater Force Main Installation (NB)
Staff recommends installation of a wastewater force main segment at the Tower 24 development using the Owner's underground contractor to perform these services.
Explanation
In July 2005, the City Commission approved construction of a wastewater force main system improvement from SW 24th Avenue to the Kanapaha Water Reclamation Facility to provide system reliability, redundancy and capacity for projected future wastewater flows as part of the FY07 Water and Wastewater (W/WW) Systems' Capital Improvements Budget.
Subsequent to beginning wastewater force main construction, a new development, Tower 24, was proposed on the SW corner of SW 24th Avenue and SW 75th Street (Tower Road). W.G. Johnson and Son, Inc. is currently performing construction services for the Owner at this site in conjunction with the Tower 24 project. Staff believes that it would be in the Utility's best interest to use the same underground contractor to install the Utility's wastewater force main concurrently to avoid potential conflicts with having multiple contractors working at the same location. Staff also believes that savings can be derived from reduced mobilization costs, volume pricing for materials and lower administrative costs.
A quotation has been obtained from W.G. Johnson and Son, Inc. in the amount of $632,269 to install approximately 1852 LF of 24 inch wastewater force main for this project. Staff has reviewed the pricing submitted by the Contractor in comparison to recently completed projects and believes the pricing is competitive for this type of work.
Recommendations
The City Commission 1) authorize the Interim General Manager, or her designee, to negotiate and execute a contract with W.G. Johnson and Son, Inc., for the installation of a portion of wastewater force main subject to approval of the City Attorney as to form and legality, and 2) approve the issuance of a purchase order in the amount of $632,269 to install a wastewater force main segment at the project known as Tower 24.
Fiscal Note
Monies for this project are available in the FY 07 W/WW Systems' Capital Improvements Budget.
