T.Y. Lin International (TYLI) provided Resident Engineering Inspection (REI) to the New York City Department of Design and Construction for the rehabilitation of interceptor sewers in Brooklyn and Staten Island. The project scope includes cleaning and lining large, high-volume sewers using centrifugally cast concrete pipe (CCCP), as well as pilot-study applications of polymer, polyurethane and spin cast geopolymer.
TYLI oversaw the inspection, coordination, management, and administration of the project from pre-construction to construction close-out. This included the oversight of all contractors’ work for conformance to plans, specifications, and contract requirements. The REI team was responsible for monitoring project progress and maintaining accurate records.
- Complex maintenance and protection of traffic (MPT) plans were developed.
- Due to proximity to other ongoing projects, TYLI developed a schedule of operations for the project.
- The project area included highly traveled roads in commercial and manufacturing zones, as well as residential streets.
