Plumbing design and documentation: You'll develop and maintain domestic water, drain-waste-vent, and water heating systems, including fixture unit calculations, pipe sizing, riser diagrams, and module-to-module connection details built for factory installation and field assembly. This includes load calculations, service and panel sizing, panel schedules, circuiting, lighting and device layouts, and single-line diagrams in Revit, coordinated with the corresponding Onshape documentation.
