Reference the Request for Proposal completion date for contract time. The contract only allows 25 calendar days to complete the work at the Mayville Interchange. The work consists of phased construction, removing and replacing the approach slab lip, approach slab and the associated barrier. Based on the NDDOT 2024 Specifications a 7 day cure time is required for each pour resulting in 21 days of cure time per phase. In addition, the penetrating water repellant treatment cannot be applied until 21 days after the slab is poured. We request the NDDOT re-evaluate and modify the calendar day count to allow a reasonable time frame to complete the phased work based on the project specifications.
