Pre-Bid Site Visit Process for Plumbing

The Pre-Bid Site Visit Process workflow helps plumbing contractors validate site conditions before submitting estimates. It covers reviewing fixture locations, checking access, identifying obstacles, and evaluating code requirements. Managers document findings, take photos, and confirm with design or client teams. By using this workflow, plumbing companies reduce estimating errors, protect margins, and improve efficiency. Clients benefit from confidence in accurate proposals. Teams gain accountability with documented assessments. With this workflow in place, plumbing contractors can strengthen professionalism, improve efficiency, and deliver projects more reliably by ensuring estimates are based on real field conditions.
