What WDF does
WDF Inc. is a New York City–based construction services firm founded in 1929 and headquartered in Mount Vernon, NY, operating as a wholly-owned subsidiary of Tutor Perini Corporation (NYSE: TPC) within its Specialty Contractors Group since July 2011. The company delivers three core service lines — General Contracting, Mechanical (HVAC, Plumbing, and Fire Protection), and Job Order Contracting (JOC) — with a fourth Green Building capability supporting LEED-certified projects. Service delivery spans Lump Sum, Design-Build, Guaranteed Maximum Price (GMP), and Construction Management at Risk (CM at Risk) contracting methods, with WDF self-performing key mechanical, plumbing, fire protection, and general contracting trades rather than subcontracting them out.
The company's technology stack centers on Building Information Modeling (BIM) integrated into a Virtual Design and Construction (VDC) initiative, Critical Path Method (CPM) scheduling across all project phases, and state-of-the-art estimating software, with in-house drafting departments that enable prefabrication of mechanical materials for time-sensitive iconic projects. WDF operates with signatory status to all major NYC unions and holds organizational memberships in NFPA, SMACNA, MCA, the Plumbing Foundation, the New York Building Congress, and the General Contractors Association.
WDF's revenue model is entirely project-based and geographically concentrated in the New York metropolitan area. Customers are predominantly government agencies and public authorities (NYC DDC, NYC DEP, NYCHA, MTA, Port Authority of NY & NJ, NYC SCA, DASNY, NYPA), large private commercial and residential developers (Related Companies, Oxford Properties, Silverstein Properties, Zeckendorf Development, The Continuum Company, AREA Property Partners), and institutional owners (NYU Langone, Columbia University, CUNY). Project values range from approximately $1.85M (15 Hudson Yards HVAC scope) to multi-billion-dollar design-build programs (Brooklyn and Manhattan Borough-Based Jails), with flagship references including One World Trade Center, 4 World Trade Center, Hudson Yards Platform, Madison Square Park Tower, 15 Central Park West, Time Warner Center, and EWR Terminal A. The company goes to market through direct enterprise sales, competitive bidding, JOC on-call task-order awards, and joint venture delivery on mega programs.
