Newport Chemical Agent Disposal Facility


Intermech fabricated and installed safety-critical and commercial-grade HVAC infrastructure throughout the Newport Chemical Agent Disposal Facility (NECDF) under a quality program that closely mirrored NQA-1 standards while meeting all schedule and project budget requirements.

The sheet metal ductwork and supports fabrication was performed at a fabrication facility that Intermech designed, mobilized, and operated at the project site. This localized fabrication facility solution was operational within 90 days of contract award and provided unique advantages to the project in terms of scheduling flexibility, rapid delivery responses, reduced transportation costs of fabricated ductwork, and an improved interface with project engineering and construction management versus using a remote manufacturing facility.

Intermech’s superior performance in the fabrication and installation of safety-critical HVAC systems has resulted in the successful award and completion of three additional major U.S. Army Chemical Demilitarization Facilities to date with a fourth major facility currently under construction.

















The U.S. Army Corps of Engineers needed a highly technological, state-of-the-art facility built in Newport, IN, for the purpose of destroying chemical agents contained in obsolete weapons in a safe and environmentally responsible manner, primarily through chemical neutralization.


Intermech, Inc. was selected by Parsons to provide fabrication and installation of galvanized and welded stainless steel ductwork systems for supply, exhaust, and recirculation air distribution systems as well as fabrication and installation of seismic duct supports and hangers for all safety-critical systems on the project.

Intermech worked with NECDF’s design and engineering staff on the design and fabrication of the HVAC duct and supports (Intermech performed the detailed design work). After Parsons’ approval, Intermech fabricated, installed, and performed critical leak testing of the HVAC systems.

Because of the toxic and hazardous nature of the substances being processed at the NECDF, the quality of the work performed was similar to nuclear quality standards and was under extensive quality review by various government agencies.


The U.S. Army Corps of Engineers provides engineering services to customers in more than 130 countries around the world. Environmental sustainability is a guiding principle as they innovate and work to strengthen U.S. security through building and maintaining America’s infrastructure. Their work includes researching and developing technology, using engineering expertise to promote stability and improve quality of life, and enhancing military facilities where servicemembers train, work, and live.
