The City of Avondale, Arizona, was under tight time requirements to make needed improvements to its water reclamation facility. As the selected Construction Manager at Risk, PCL (working with the owner and engineer) subdivided the work into three sub-projects (GMP-1, GMP-2, and GMP-3) to accomplish the work within the time allowed. This provided the means to price and begin varying parts of the project at staggered intervals, shortening the overall project duration.
GMP-1 included modifications to the existing aeration basins. GMP-2 included the procurement of all major pieces of equipment. GMP-3 consisted of all the PCL self-performed work for the new construction items. The project increased the treatment capacity from 4.2 million gallons per day to 9.0 million gallons per day. The new construction upgraded the effluent water quality from level B solids content to level A, which allowed the reclaimed water to be used for groundwater recharge.
