Resolution to Approve Amendment No. 4 with Malcolm Pirnie, Inc. for Design of the Facilities Renovations Project at the Wastewater Treatment Plant ($2,410,347.00)
Memorandum
We request your approval of Amendment No. 4 to the Professional Services Agreement with Malcolm Pirnie, Inc. (MPI) in the amount of $2,410,347.00 to complete the design and bid 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 older West Plant portion of the WWTP was first constructed in the 1930's and the newer East Plant was constructed in the late 1970's.
The West Plant has exceeded its useful life and was taken out of service in 2006 due to its dilapidated condition. Replacement of the West Plant is necessary for the WWTP to reliably meet current and future wastewater treatment capacity requirements. 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. Construction of the FRP must be done without impeding the flow of wastewater into the WWTP or the plant’s ability to effectively treat the flow in compliance with regulatory requirements.
Based on the selection criteria listed in RFP No. 584, MPI was selected as the most qualified engineering firm to provide the needed engineering design services. MPI is producing final bid drawings (approximately 600 sheets) and specifications to be used for securing necessary permits and soliciting bids from qualified contractors. Due to the magnitude and complexity of the FRP, the complete scope of services for design of the project could not be full...
