Title
Resolution to Award a Contract to DLZ Michigan, Inc. to Design Repairs to the Wastewater Treatment Plant Access Bridge ($32,752.07)
Memorandum
Your approval is requested to award a Professional Services Agreement in the amount of $32,752.07 to DLZ Michigan, Inc. (DLZ) for engineering services to design short term repairs to the access bridge for the City's Wastewater Treatment Plant (WWTP). The bridge was first constructed in 1934, and traverses the Huron River to provide access to the plant. The bridge also conveys three sanitary sewers and one natural gas line. Improvements to the bridge were made in 2000 when the bridge deck was overlaid, the railings and guardrails were replaced, the expansion joints were replaced, and the substructure was patched.
Under the supervision of the City's Project Management Unit, DLZ conducted a bridge inspection on October 14, 2012, and found the structure to be in fair condition with significant metal and concrete corrosion present. DLZ recommended that the City implement short term repairs to address the corrosion problems and implement long term improvements to extend the lifespan of the bridge. The short term improvements are scheduled to be completed this year and the long term improvements are planned after completion of the WWTP Facilities Renovations Project in 2017. Heavy traffic due to the Facilities Renovations Project makes it impractical to implement long term improvements now.
On December 20, 2013, the City's Procurement/Purchasing Unit advertised RFP No. 875 for engineering services to prepare detailed plans and specifications to bid and construct the short term repairs. On January 10, 2014, the City received one proposal from DLZ in the amount of $15,945.76 for the project. Upon receiving only one proposal for this project, WWTP staff asked several engineering firms why they did not respond. Concerns about having to subcontract a portion of the specialized scope of work as well as the re...
