This $40 million Construction Manager at Risk (CMAR) project for the City of Plant City, Florida, included a 12 MGD expansion and upgrade of the existing facility. The project required excavation and removal of 90,000 CY of unsuitable soil and the import of 90,000 CY of fill. The project was built in two phases to allow the treatment plant to remain online throughout the entire construction process. The administration building was built to withstand a Category 5 hurricane since it would be used as a storm command center during weather emergencies. The new treatment system utilized a sophisticated nutrient analyzing system that resulted in the use of less chemicals and electrical power to treat the waste streams. The project also included the construction of new aeration and anoxic basins, three final clarifiers, a RAS/WAS pump station, a filter addition, chlorine contact basin expansion, and lastly, the installation of a ground storage tank, a blower building and an administration building. Process improvements included new electrical, instrumentation, high service reuse pumps and belt filter press modifications.
“I would like to take a moment to commend your team on the outstanding work performed for the City of Plant City in the expansion and upgrade of our water reclamation facility. This was undeniably a complex project overlain on a complex site. I believe that your involvement in the Pre-construction Phase was key in avoiding many of the ‘maintenance of operations’ issues involved in retrofitting an existing facility.”
