Project Summary

Beginning shortly after occupancy of the Northeast Correctional Center, the facility began to experience corrosion failure in both the heating and domestic hot water underground distribution systems. The condition of the piping system had reached critical status and threatened to shut down the entire facility, requiring the relocation of thousands of incarcerated offenders.

Klingner was selected via a qualification-based selection process by the Missouri Office of Administration – Facilities Management Design & Construction to provide all of the professional engineering services required for the replacement of the existing underground piping system. Klingner analyzed 10 different replacement system options, and the State of Missouri made the ultimate decision to utilize a pre-insulated fiberglass reinforced plastic piping system. The design requirements for fiberglass piping systems are very different than the design requirements for the traditional metallic piping system used in the original project design and had to be fully accounted for in the project design. In addition to the selection of the pipe material, Klingner was also responsible for designing a project that could be constructed within a fully occupied correctional facility. The construction of the replacement piping system could not interrupt existing utility services or otherwise disrupt the operation of the correctional facility. Ultimately over 20,000 LF of pipe was installed in over 5,000 LF of trench on time and on budget, and the system is operating successfully.

This project was selected as an Honor Award winner in the 2017 ACEC-Missouri Engineering Excellence Award Competition. It also caught the attention of national magazine “Plumbing Engineer”, which made the project their featured cover story for April 2018’s Issue.
