Title
Resolution to Approve an Emergency Purchase Order with E.T. MacKenzie to Repair Storm Culvert on Dhu Varren in the Amount of $82,963.00
Memorandum
Field Operations received a report of a depression in the middle of Dhu Varren Road. Upon investigation, it was determined that the existing 54" corrugated storm culvert had deteriorated and storm water flow undermined the road bed causing the depression. In that Dhu Varrren was the planned detour route for the Pontiac Trail road reconstruction project scheduled to begin June 16, 2014, it was necessary to make the repairs immediately. As a result, 65 LF of existing 54" CMP (corrugated metal pipe) between existing manholes on Dhu Varren, was replaced with 54" RCP (reinforced concrete pipe).
Field Operations was able to solicit 2 bids for the repair. The repair included the removal of the failed culvert, installation of a new reinforced concrete pipe, restoration of the roadbed and paved surface. E.T. MacKenzie Company provided a quote for $76,882.60 to remove the failed existing culvert, install a new reinforced concrete pipe, restore the roadbed and restore the paved surface. Evergreen Civil provided a quote of $97,210.00. Higgins Construction declined to bid based on staff availability.
E.T. MacKenzie was authorized to make the immediate repair. During excavation and subsequent repair it was determined the downstream manhole was too small to receive the new pipe, resulting in an increased cost to the original scope and cost of the repair.
Funding for the repair is available from the Storm Water Capital Maintenance Budget.
