Septic system improvements

The Mackinac County, Michigan, through the Whiteford Agricultural School District, is seeking bids for a comprehensive septic system improvement project to be completed by August 30, 2018. The procurement involves constructing a new pressurized mound disposal field system, including a 2000-gallon septic tank, 5000-gallon equalization tank/pump chamber, duplex effluent pumping system, control panel, and associated infrastructure. Sealed bids are due on May 10, 2018, at 1:30 PM at the school district office, with a mandatory pre-bid meeting scheduled for May 3, 2018, at 1:30 PM at the project site. Contractors must provide a 5% bid bond and performance and payment bonds at 100% of the contract amount. The project requires substantial completion by August 20, 2018, with contractors having 5 weeks from commencement to reach this milestone. Technical specifications include precise installation requirements for tank systems, distribution pipes, monitoring ports, and disposal field components, with specific guidelines for materials like natural filter stone and perforated piping.

The procurement does not explicitly indicate set-aside designations or restrictions for disadvantaged enterprises. A $5,000 contingency allowance is included, which requires owner and engineer approval for use. The project offers an alternate bid option for using 4 feet of health department-approved local sand instead of 3 feet of 2NS sand for the disposal field system. While specific budget ranges are not directly stated, the comprehensive nature of the project involving multiple system components suggests a potentially significant investment. The project is being managed by OHM Advisors, who prepared the engineering drawings and specifications, which were approved by the Monroe County Health Department in April 2018. The system is designed to handle daily flows of 2,345 gallons, with a total equalization storage volume of 10,023 gallons, indicating a substantial infrastructure improvement for the Whiteford Agricultural School District.
