The contractor must complete all contract activities in a single day per bridge location within an eight-hour period, with work limited to daylight hours and one lane closure at a time as MDOT provides traffic control. Key deliverables include debris removal, wash water management, manifests documenting material volumes transported to approved disposal sites, and confined space entry permits obtained by the contractor. Required qualifications include Michigan industrial waste hauler licensure with confined space work permits and subcontractor documentation submitted at bid time.
