Title
Resolution Approve a Construction Contract and to Ratify an Emergency Best Source Purchase Order with E.T. MacKenzie Company for Repairs to the Sanitary Sewer Main on Hilltop Dr. ($224,812.20)
Memorandum
Public Works staff was called to a sewer backup at 3125 Hilltop Drive on Friday, November 3rd. Staff worked on the backup for several hours before reestablishing flow in the sewer main. The following Monday, a camera used in the investigation into the cause of the blockage dropped into a hole in the bottom of the sanitary sewer pipe and became stuck. A second camera was deployed from the upstream manhole, and an unknown obstruction was located. Staff was unable to remove the obstruction or retrieve the fallen camera. The sewer is 18’ deep and Public Works is not equipped to safely perform the deep excavations necessary to make the repairs and retrieve the camera.
RFP#23-55 for Public Works on-call construction services was publicly opened on October 10, 2023. A selection committee comprised of Public Works staff reviewed the proposals and determined the proposal from E.T. MacKenzie Company provided value based on the criteria in ORD-21-41, adopted by Council on January 3, 2022. A construction contract award to E.T. Mackenzie Company is set for the City Council agenda on December 4, 2023. They were contacted to provide pricing for the emergency repairs using the rates submitted with their recent bid. The bid totaled $224,812.20.
Public Works requested the authorization of an Emergency Best Source Purchase Order to E.T. MacKenzie Company in the amount of $224,812.20. E.T. MacKenzie Company successfully completed both of the necessary repairs on November 16th and mitigated our risk of basement backups or an SSO. Therefore, we request that City Council ratify the Emergency Best Source Purchase Order in the amount of $224,812.20
As provided in the City of Ann Arbor’s Code of Ordinances, Title I, Chapter 14, Section 1:317, the Public Works Unit received authorization for an emergency purchase order to E.T. MacKenzie Company in the amount of $224,812.20.
E.T. MacKenzie Company complies with the requirements of the Conflict of Interest, Non-Discrimination, Prevailing Wage, and Living Wage ordinances.
Budget and Fiscal Impact: Funds for this emergency purchase order are available in the approved Sanitary Sewage Disposal Operations and Maintenance Budget.
