Septic System Improvements

Mackinac County is overseeing a septic system improvement project for the Whiteford Agricultural School District located in Ottawa Lake, Michigan. The procurement involves construction of a comprehensive new pressurized geotextile sand filter system, which includes installing a septic tank, equalization tank, pump chamber, duplex effluent plumbing system, and pump control panel. The project requires connecting existing piping and electrical systems, abandoning the current pump chamber, clearing trees, and completing site restoration. Sealed bids were due on February 23, 2018, at 1:30 PM at the Whiteford Agricultural School District office, with a mandatory pre-bid meeting held on February 13, 2018, at the project site. The project timeline mandates substantial completion by July 20, 2018, and final completion by July 30, 2018. Bidders must submit a 5% bid security bond and provide performance and payment bonds covering 100% of the contract amount. Additional required submission documents include familial relationship disclosure and Iran Economic Sanctions Act compliance affidavits.

The contract will be awarded as a single prime contract using AIA Document A101-2007 Owner-Contractor Agreement, with a $5,000 contingency allowance that can only be utilized with prior owner/engineer approval for unforeseen project costs. Procurement documents were available for free download from OHM Advisors' FTP site or as hardcopy for a $50 non-refundable fee. The technical specifications detail a daily flow calculation of 2,385 gallons with a total septic tank retention time of 2.26 days. The disposal field will encompass approximately 120' x 95' and includes five disposal field zones with perforated pipe distribution systems. While no specific set-aside designations or disadvantaged enterprise requirements were mentioned, the project involves detailed technical specifications that would likely require contractors with specialized expertise in municipal and educational infrastructure construction, particularly in septic system design and installation.
