Shapiro & Duncan is the "Mechanical Construction Solutions Provider of Choice" for complex commercial, government and institutional design-build projects that require first-rate performance, work quality and customer service. Shapiro & Duncan is unique in the way it uses Building Information Modeling (BIM) and Integrated Project Delivery to promote sustainability and ensure customer satisfaction. BIM, which incorporates the latest AutoCAD and CADPipe programs, is used on every project to produce composite mechanical drawings in 3D for planning, fabrication and installation of mechanical components.

Mechanical construction of HVAC and plumbing systems by Shapiro & Duncan involves extensive coordination of equipment delivery, trades, subcontractors and the general contractor. Often, we serve as the prime contractor working directly with the owner. In addition to HVAC and plumbing systems, prime mechanical construction projects can include replacement or upgrading of fire alarm systems, sprinkler systems, ceiling systems, roof systems and electrical/lighting systems. At Shapiro & Duncan, successful mechanical construction is driven by professional project management.

Shapiro & Duncan provides an array of money saving pre-construction services to owners, architects, engineers and general contractors. We ensure clients obtain competitive prices by preparing a detailed project scope analysis prior to soliciting proposals from preselected and pre-qualified subcontractors and vendors. By using on-screen takeoff, we have refined the estimating process to produce extremely accurate quantity takeoffs that automatically apply current cost data. Employing the principles of value engineering at the design stage of a project, we develop optional or alternative methods for delivering an equal or better result at a reduced cost to our clients.
