Section 3 Business Preferences apply to qualifying firms, with preference points ranging from 3 to 15 based on ownership and workforce composition criteria. Proposers must demonstrate compliance with Equal Employment Opportunity and supplier diversity requirements, including utilization of small, minority-owned, and women-owned businesses.

The scope encompasses general plumbing maintenance and repairs, emergency response capabilities, staff training (two sessions annually), daily and weekly reporting, and monthly coordination meetings with Agency staff and residents. All work must be supervised by a licensed Master Plumber and performed at multiple locations throughout Inkster, Michigan.
