What Harding & Smith does

Harding & Smith, Inc. is a privately held mechanical and instrumentation/control (I&C) contracting firm founded in 1975 and headquartered at 2000 Main Street, Walpole, Massachusetts. The company designs, fabricates, installs, and commissions large-scale mechanical infrastructure — sophisticated process piping, plumbing, HVAC, and instrumented control systems — for water and wastewater treatment facilities, highways, bridges, tunnels, airports, and industrial plants. Operations are anchored by a 21,000 sq. ft. office and fabrication facility in Walpole, MA, approximately 30 minutes from Boston and Providence. The firm is DBE-certified and led by CEO Jaana Lucek, who drove the certification milestone and has signaled continued operational expansion.

The company's three core service lines are Mechanical Systems (plumbing and HVAC for commercial, institutional, biotech, and industrial facilities, including prefabrication in a controlled quality environment), Process & Treatment Systems (design, construction, fabrication, and maintenance for biotech, waste/water treatment, pharmaceutical, and power industries), and Instrumentation & Control Systems (full-service I&C from initial design through construction to operation, including shop fabrication of equipment modules, skid-mounted assemblies, instrument panels and racks, piping subassemblies, structural components, and weldments, plus calibration, loop checking, and functional testing). Supporting capabilities include non-destructive examination (visual, dye penetrant, radiographic, ultrasonic), NIST-traceable instrument calibration, CAD-based engineering design, and quality assurance aligned to ASME, IEEE, ANSI, and AWS standards. The company claims international deployment of "World Class I&C Products" across North and South America, Europe, Asia, and Africa, although primary project delivery is concentrated in New England.

Revenue is generated on a project basis through competitive bidding on public and private capital projects, with Harding & Smith engaged either directly by government owners or as a pre-qualified subcontractor to major general contractors including Turner Construction, Skanska, JF White, Bond Brothers, Barletter Heavy Division, CH Nickerson, and SPS. Customer work is overwhelmingly government and quasi-public — examples include the Deer Island Sewer Treatment Plant (Boston Harbor Cleanup), the Big Dig, Metro West Tunnel, Logan Airport, Massport Conley Terminal, Union Station, and the Kenneth F. Burns Memorial Bridge. Pricing is not publicly disclosed. The business model is project-based, lump-sum and unit-price contracting with no recurring software or SaaS revenue component.
