How do I schedule rough-in vs. trim-out phases for my trade crew?

Schedule rough-in and trim-out as separate visits with their own durations, crews and readiness checks, and treat the gap between them as a planned wait, not as a job that is still running. The two phases can be weeks or months apart, and each one starts only when someone else's work is finished.

What the phases are

For electrical, plumbing and HVAC subcontractors the work normally breaks down like this:

1. Underground or slab rough. Before the slab is poured.
2. Rough-in. Pipe, wire, duct and boxes in open walls and ceilings, before insulation and drywall.
3. Inspection. Rough inspection, and pressure or other tests.
4. Trim-out (finish). Fixtures, devices, grilles and equipment connections, after paint and flooring.
5. Startup and commissioning. Testing, balancing, final inspection, and owner training.

Other trades have their own versions: a concrete crew forms, pours, cuts and seals with a cure time in between.

Why one line on the schedule does not work

A single bar from first day to last day says the crew is on that job for four months. They are not. They are there for two weeks, gone for ten, back for one. A schedule that cannot show the gap hides the crew's free time, so you either overbook them or turn away work you could have taken.

Estimate and bill by phase

Break the estimate the same way the work breaks. Rough-in and trim-out have different labor, different material, and often different people. Carry those lines into the schedule of values, so that rough-in can be billed when it is done and you are not waiting for trim to bill for work finished three months earlier.

Each phase has a gate

Do not mobilize on a date. Mobilize when the conditions are met.

Before rough-in:

• Framing complete and walls laid out
• Sleeves and penetrations located
• Material and fixture rough-in sheets on site
• The trades that go before you are out of the way

Before trim-out:

• Rough inspection passed
• Drywall finished and painted
• Flooring, cabinets and counters in, where your work needs them
• Fixtures and devices delivered and checked against the submittals
• Permanent power or water available for testing

Check the gate the week before and again the day before. A wasted mobilization costs a day of crew time plus the job they were pulled from.

Follow the general contractor's schedule, not your memory of it

The date for trim was a guess when you signed the contract. Ask for the look-ahead schedule every week, and adjust your own return date as the project moves. When drywall slips two weeks, your trim date slipped two weeks, whether or not anyone told you.

Price the remobilization

Every return trip has a cost: loading, travel, setting up, finding where you left off. If the GC breaks your rough-in into four visits where your bid assumed one, that is a change. Your proposal should state how many mobilizations the price includes.

Keep the same lead on both phases

The foreman who roughed the building knows where everything is. Sending a different crew to trim it means an hour of hunting for every box that got buried. When you cannot keep the same people, keep the photos and marked-up drawings from rough-in with the job.

Finish the punch list in the same trip

Trim-out is when small defects show. Leave time at the end of the visit to walk it, fix what you find, and get a sign-off before the crew leaves. A fifth trip for three cover plates costs more than the plates.

Where ConstructStream fits

In ConstructStream a product is made of phases: work phases with a production rate, fixed phases, and waits that take calendar days with no crew. Booking a job lays out a separate visit for each phase with the wait in between, so the crew shows as free during the gap. A later visit can be moved on its own without moving the first, and a planned versus actual report shows how many days each phase really took.
