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.
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.

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.

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.
