Resolution to Approve Amendment Number 4, to the Professional Services Agreement with Tetra Tech, Inc. for the Ann Arbor Landfill Monitoring and Maintenance Program and Appropriate ($124,907.73) (8 Votes Required)
Memorandum
Attached for your review and approval is a resolution for Amendment No. 4 to the Professional Services Agreement with Tetra Tech, Inc. (R-17-255 & R-19-319) for environmental consulting services for the Ann Arbor Landfill Monitoring and Maintenance Program, through June 30, 2021. This resolution will increase the professional service agreement by $124,907.73 bringing the total contract value to $476,031.73 with an additional $40,000.00 contingency amount.
Amendment 4 is needed to perform necessary repairs and maintenance to one of the wells used in the landfill monitoring program and to repair a small portion of the landfill cap that has thinned over time. These repairs exceed the scope of routine maintenance anticipated when the original contract and budget were set, but are necessary to remain in compliance with state regulations. The well work includes installation of valving, replacing a section of discharge piping and acid cleaning. The landfill cap repairs includes grading and placement of additional clay and topsoil in areas where the cap has thinned from settling and erosion.
Budget/Fiscal Impact: The increased maintenance required was not anticipated; therefore, not included in the approved Solid Waste Fund budget. Funding for this required maintenance is available in the Fund Balance of the Solid Waste Fund.
