Memorandum
We request your approval to award a Professional Services Agreement to Malcolm Pirnie, Inc. (MPI) for $10,802,423.00 for engineering services to support construction of the Facilities Renovations Project (FRP) at the City's Wastewater Treatment Plant (WWTP).
The purpose of the FRP is to construct the renovations identified in the Ann Arbor WWTP Facilities Master Plan. The WWTP Facilities Master Plan is a comprehensive, 25-year planning document that provides the basis and schedule for rehabilitation and replacement of major equipment at the WWTP. The WWTP consists of two treatment plants at a single site, the older West Plant first constructed in the 1930's and the newer East Plant constructed in the late 1970's.

Replacement of the West Plant is necessary for the WWTP to reliably meet current and future wastewater treatment capacity requirements. Renovations to the West Plant include rehabilitating existing flow control structures, complete demolition and replacement of primary and secondary wastewater treatment equipment and systems, and construction of new buildings. In addition to the complete demolition and replacement of the West Plant, the FRP includes miscellaneous renovations and improvements throughout the facility to maintain treatment viability and reliability. Site-wide improvements include installation of a new electrical distribution system and two new emergency power generators, utilities relocation, replacement of stormwater collection system equipment and systems including installation of best management practice features (i.e., rain gardens, porous pavement, grass swales, zero-net runoff areas, and hydrodynamic separators), instal...
