Commercial electrical rough-in coordination before walls close

Before walls, ceilings or trenches close, agree on where electrical equipment and connections go, which routes need to stay open, and which inspections are due. Give the electrical contractor the current plans, equipment details and a named contact who can resolve field changes.

Start with the current set and the actual equipment

Put the current electrical, architectural and mechanical sheets in one place with their revision dates. Identify the equipment that has been selected and share its connection information. Mark items still awaiting approval. If a fixture, appliance or mechanical unit moves, identify its new location and ask the responsible design or project contact to confirm the change before the electrical work that depends on it goes ahead.

Walk the routes with the trades that share the space

Use a coordinated plan or a site walk to discuss equipment locations and routes through ceilings, walls, equipment rooms or underground areas. Identify where plumbing, ducts, framing or cabinetry may compete for space and who is responsible for resolving each conflict. Keep a list of open decisions with the affected room or plan reference and the date the next trade needs an answer.

Confirm inspection and close-up sequencing

For permitted work in the City of Los Angeles, LADBS directs project teams to request inspection before covering or concealing work and keep the work visible for inspection. Confirm the required steps with the authority that issued your permit. Agree on who schedules the inspection, who keeps the approved plans available and who tells the next trade when the area can close. Report changes to the approved scope through the project’s designated contact.

Document what will disappear from view

Have authorized site staff record useful locations and approved changes from safe positions before the work is concealed. Label photos by room or plan reference and date so someone can find them later. Keep photos and marked drawings with the project records. Inspection signoffs and approved field changes belong in those records too.

Compare photographs by stage and scope

Our Los Angeles commercial floor fit-out shows the bare space, installation work and installed lighting. The Rancho Cucamonga college case study shows open ceiling framing and wiring during food-service work, followed by views of the finished lighting from other positions. Our Burbank example covers an underground-fed single-meter socket. Use these different scopes to discuss what will be visible at each stage of your project and what needs to be recorded before it is covered.
