Key project requirements include clearing debris, managing root intrusion, installing bypass pumps, and providing post-installation video documentation within ten working days. Contractors must comply with ASTM F1216-22 and ASTM F1743-21 standards and provide a 6-by-6-inch cured liner sample with a minimum 9mm wall thickness. The bid submission deadline is November 23, 2022, at 2:30 PM, with questions due by November 14, 2022, at 12:00 PM. The contract is estimated to commence on January 2, 2023, and conclude by March 31, 2023, with an anticipated project duration of approximately three months.

No specific set-aside designations or restrictions on respondents are mentioned in the solicitation. The procurement will be awarded to the lowest responsible and responsive bidder, subject to approval by the South Carolina Transportation Secretary. Vendor registration with the state is mandatory for bid submission. SCDOT will provide traffic control, while the contractor is responsible for obtaining appropriate licenses and permits and maintaining commercial general liability insurance with minimum limits of $1,000,000 per occurrence. The contractor will have access to water from the SCDOT meter at a laydown yard located at 593 Sniders Highway in Walterboro and may dispose of solids at the same facility.

The project involves removing approximately 12 inches of existing metal pipe running longitudinally within the 18-inch pipe during the cleaning process before installing the CIPP liner.
