Shapiro & Duncan provides pre-construction services to owners, architects, engineers, and general contractors. Integral components of our pre-construction services are quantified budgets, value engineering, advance equipment procurement, existing system analysis, and site condition surveys.

Shapiro & Duncan provides single-source HVAC and plumbing systems design-build capability for both new and retrofit construction projects. Led by registered Professional Engineers, our in-house design-build service teams reduce cost and accelerate project completion for owners and general contractors. We do this by providing upfront detailed cost projections with a menu of options early in the planning phase, allowing informed decision-making during the design stage, which can also prevent costly change orders during project construction. All of our design-build work is handled by our seasoned engineering staff, who possess in-depth knowledge of the Maryland, Virginia, and Washington, DC building codes ensuring code compliant work. Upon completion of the project, Shapiro & Duncan can also maintain the equipment providing our clients with one stop responsibility from design through years of equipment maintenance care.
