Resolution to Approve a Professional Services Agreement with Orchard, Hiltz & McCliment, Inc. ($96,538.00) for the Design of Stadium/Iroquois Water Main Replacement and the Harvard Drain Stormwater Quality Improvement Projects
Memorandum
Attached for your review and approval is a resolution to approve a Professional Services Agreement in the amount of $96,538.00, with Orchard, Hiltz & McCliment, Inc. for the design of Stadium/Iroquois Water Main Replacement and the Harvard Drain Stormwater Quality Improvement Projects.
The existing 4 & 6-inch water mains in East Stadium Boulevard and Iroquois Place are in poor condition and do not have adequate pressure for fire flow capability. The project consists of installing approximately 3,350 feet of new 8-inch ductile iron pipe water main at East Stadium Boulevard and Iroquois Place. Estimated cost of the water main design is $68,001.00.
The existing storm drain pipe at Harvard Place follows the steep gradient of the hill, emptying into the Nichols Arboretum causing erosion, sedimentation and the de-stabilization of the streambank. The design will reduce outlet velocities to minimize erosion and undercutting in the Nichols Arboretum. The University of Michigan has plans to design and construct a stormwater infiltration project at the outflow area to further mitigate the problem. The project consists of designing an underground water treatment structure designed to reduce the velocity of the water. Possibilities include a drop structure, a vortex-type treatment structure, in-pipe baffles, or a combination of these. Estimated cost of the stormwater design is $28,537.00.
The 2006-11 Capital Improvements Plan rates the Stadium/Iroquois Water Main Replacement project, and the Harvard Drain in Nichols Arboretum project as Important. Funding was approved for both projects during the FY08 Capital Budget process.
In November 2007, a request for design proposals (RFP #686) was issued through the Procurement Serv...
