Resolution to Approve a Construction Contract with Z Contractors, Inc. for the 2190 South State Street Retaining Wall Replacement Project, RFP 23-11 ($179,746.05).
Memorandum
Attached for your review and approval, please find a resolution to approve a construction contract between the City of Ann Arbor and Z Contractors, Inc. in the amount of $ $179,746.05 for the 2190 S. State Street Retaining Wall Replacement Project (RFP 23-11).
The scope of this project is to replace the failing, city-owned timber retaining wall with a modular block retaining wall. The construction of the project is scheduled to occur between July and October of 2023. No work will occur during the week of Art Fair, and pedestrian access will remain open.
Engineering staff supervised the creation of plans and contract documents and issued a request for proposals for the project through the City's Procurement Unit. On April 25, 2023, one proposal from Z Contactors, Inc. was received for this work. A selection committee comprised of Public Services staff evaluated the proposal based on the criteria in ORD-21-41:
* Qualifications, Experience, & Accountability (20%)
* Workplace Safety (20%)
* Workforce Development (20%)
* Social Equity & Sustainability (20%)
* Schedule of Pricing/Cost (20%)
The original RFP (23-11) included the installation of a new stone-veneer retaining wall, located at Geddes Ave and Onondaga. The total proposed cost for this wall greatly exceeded the engineer's estimate and budget. Engineering staff reviewed the proposal and determined to remove the Geddes wall from the project, re-design it, and bid it separately, for construction in 2024. Because Z Contractors was the sole proposer, an updated bid form of only items pertaining to 2190 South State Street wall was negotiated with Z Contractors. The new proposal was reviewed and found to be reasonable. Therefore, staff recommends approving a contract with Z Contractors, Inc. for this project.
