What Ruthrauff Sauer does

Ruthrauff | Sauer, LLC is a full-service mechanical contractor headquartered in McKees Rocks, Pennsylvania, serving the Greater Pittsburgh tri-state area (Pennsylvania, Ohio, West Virginia). Founded in 1876 as a plumbing contractor and now operating as an LLC under Sauer Holdings (alongside Sauer Inc., Sauer Group, and Ruthrauff Service), the company delivers HVAC construction, plumbing, industrial and process piping, sheet metal and pipe fabrication, building automation, and 24-hour service and maintenance. Its 'Single Source Advantage' positioning bundles engineering, pre-construction, BIM coordination, fabrication, and field installation under one contract, primarily for healthcare systems (UPMC, St. Clair, Excela, Jefferson Regional, Forbes Regional, Sewickley Valley), higher-education and research institutions (Carnegie Mellon, University of Pittsburgh, Duquesne, Point Park, Bechtel Bettis), commercial office towers (K&L Gates, One Mellon Center, 3 PNC Plaza, Shell Pittsburgh), sports and entertainment venues (Heinz Field, Rivers Casino, Petersen Events Center), industrial clients (U.S. Steel, Allegheny Ludlum), and Marcellus Shale energy operators (Markwest, Stewart/Baker compressor stations).

The company's underlying technology centers on Building Information Modeling using Quickpen DD3D/PD3D inside AutoCAD, Autodesk Navisworks Manage for automated clash detection, and a CAD-to-plasma-cutter fabrication pipeline for sheet metal and pipe. UPMC East was the first Pittsburgh-area hospital construction project to be fully coordinated via 3D models and electronic clash detection. In-house engineering (led by VP Gordon Collins, a LEED-accredited PE) supports design/build and design/assist delivery, value engineering, and constructability review across all major project stages.

Revenue is generated through project-based mechanical construction contracts (fixed-price, negotiated, and design/build) plus a recurring 24-hour HVAC and plumbing service stream. Go-to-market is exclusively direct enterprise field sales — no distributors, resellers, or marketplace channels — targeting building owners, architects, and project developers in the Greater Pittsburgh tri-state area. Pricing is custom, quote-based per project; no published tier pricing exists. The firm is privately held, employs 101-250 people, and is led by President Raymond G. Gajski (industry veteran since 1974), VP/GM Robert D. Burger Jr. (with the firm since 1998), and other long-tenured executives.
