Construction Management at Risk

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 Newfield Construction is proud to be a part of. The project meets 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, conference areas, and crew shops for carpentry, plumbing, electrical, signage, radios, and materials storage. The project also includes parking for over 260 vehicles and creating an off-site outdoor materials storage area. Roof construction consists of a membrane roof with pavers, flashings, vents, curbs, drains, and 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, frames, overhead doors, aluminum windows and storefront, hardware, glazed aluminum curtain walls, and skylights.

One of the leading construction challenges was relocating an existing 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 essential factors of the project’s success. 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, controls, fire alarm systems, and electronic safety and security also make up the significant utilities for this building.

All systems approved by the Commissioning Authority and all subcontractors provide support for the demonstration of start-up and operation, including all required system adjustments.

Project close-out includes a punch list, as-built drawings, and owner training.
