Maintenance of Way Building

Newfield Construction acted as Construction Manager at Risk for the Department of Transportation’s 31,000 sf Maintenance of Way Building, which included multiple adjacent site developments. This project is the CT DOT’s first Construction Management at Risk contract, one of which Newfield Construction is proud to be a part of. The project adheres to the State of Connecticut’s High Performance Building Standards criteria.

The MOW building is a two story pile-supported steel-framed building with a loading dock to allow access for materials and equipment to be loaded to and from the shops within the building that maintains the rails of the New Haven Line. The building houses offices, supervisor quarters, locker rooms, kitchen and vending areas and conference areas as well as crew shops for carpentry, plumbing, electrical, signage, radios, as well as materials storage. The project also includes parking for over 260 vehicles as well as creation of an off-site outdoor materials storage area. Roof construction consists of a membrane roof with pavers, flashings, vents, curbs, roof drains, and roof hatches.

Interior finishes include painted gypsum board, porcelain tile and concrete block and masonry. Floor coverings include porcelain tile and vinyl tile. Ceilings are acoustical tile, gypsum board and metal panels. Architectural wood casework composite material wall panels, prefabricated structures and fire suppression systems were constructed and installed within the building structure. Doors and frames, overhead doors, aluminum windows and storefront, hardware, glazed aluminum curtain walls and skylights.

One of the main construction challenges was relocating an existing through street from the new parking lot to the middle of the project site. The critical interface with the utility companies and the coordination with other contractors constructing other buildings on adjacent parcels in the rail yard were key factors in the success of the project. Grading and stormwater management, site features, excavation and fill, paving, sidewalks, signage, striping and fencing were all part of the site work for this project. Civil utility work in support of the building included subsurface gas, electric, water, sewer, communications, drainage lines and sanitary pump station. Plumbing, HVAC systems and controls, fire alarm systems and electronic safety and security also make up the major utilities for this building.
