reservoir renovation project

The above-ground, off-stream reservoir is a vital component of Tampa Bay Water's surface water system. The reservoir came on line in 2005, but in December 2006, cracks began to form in the soil cement interior face of the facility's erosion control structure. Over time, the cracks became larger than expected and appeared in several areas on the reservoir's interior face.

To ensure long-term reliability and functionality of the facility, Tampa Bay Water’s Board of Directors approved procuring a permanent fix for the reservoir’s soil cement erosion control layer. A permanent fix is required for the facility to be used at its intended fill and drawdown rates.

The agency selected the Design-Build-Maintain procurement option for its Reservoir Renovation Project because the maintenance component provides value on short- and long-term maintenance. It also ensures the successful contractor stands behind its work until the fix is deemed successful.

Three design-build teams were pre-qualified to participate in the reservoir renovation procurement process. Each team submitted a base proposal to renovate the facility so that it performs as originally intended as well as an alternate proposal for 3 billion gallons of additional storage. Those teams were:

• Granite Construction Company
• Kiewit Infrastructure South
• Skanska USA Civil Southeast

The proposal stage took a "best value" approach to securing the best long-term fix at the right prices. It is not a low-bid procurement. Continued on page 2
