G&W prepares the documentation architects, owners, and project teams need to engage a design-build MEPFP contractor with clarity. Scope typically includes design-build narratives, outline specifications, performance criteria, and Design Development-level drawings. These documents define system intent, establish space and load allocations, and set the performance targets the design-build team will execute, with fire protection criteria coordinated in the same set so sprinkler and standpipe requirements are settled before the work is priced.
On design-build projects where G&W delivers the mechanical engineering, work progresses in parallel with procurement and construction planning. HVAC design, equipment selection, and installation documentation develop in step with lead times and sequencing. Early contractor input improves equipment decisions and reduces field conflicts. Load calculations, ventilation rates, and control sequences are documented so the mechanical contractor can order equipment without waiting on clarification.
As part of a design-build team, G&W’s electrical scope covers power distribution, lighting, fire alarm, and low-voltage systems, developed in coordination with contractors from early design through closeout. Working alongside the construction team sharpens equipment selection, improves drawing-to-field accuracy, and minimizes change orders. Service sizing, panel schedules, and circuit layouts are issued in a form the electrical contractor can install from directly.
For design-build plumbing scopes, constructability drives the design. Domestic water, sanitary, storm, and specialty piping systems are detailed in coordination with field sequencing, trade handoffs, and equipment procurement. Close contractor involvement during design sharpens routing decisions and reduces installation rework. Fixture counts, pipe sizing, and water heating capacity are set early so rough-in can start without a redesign.
