Plumbing and electrical installations have to be coordinated with the other trades and contractors, and it usually requires a number of visits from plumbers and electricians. So for instance, these installations could include:
Check plumbing and electrical is complete and sound before next stage
It can be seen that plumbers and electricians may have to return to the project four or more times, and air-conditioning contractors usually two or three times. It’s important to check that all electrical wires and ducts and all plumbing pipes have been installed correctly, at the right location, with no visible leaks and faults, before:
Coordinating the trades during construction
But even these trades must be coordinated between them. Plumbing waste and sewer pipes have to be installed at the exact locations and levels. They usually have little room to change so they should be installed first. Air-conditioning ducting is usually premade in sections, unless it’s flexible ducting installed for smaller airflow or at the ends of the main ducts. So non-flexible air-conditioning ducts should be installed next. Water pipes can go up or down and there’s some flexibility in location so they’re installed next. Electrical wiring has the most flexibility, so can be installed last. However, having said this, it’s important to note that pipes and ducts can’t obstruct where lights, switches and outlets must go.
