The Jobsite: How a Project Comes Together

Before you pick up a tool, understand who does what and what order things happen in.

The players

• Owner — pays for the project.
• Architect / engineer — designs it.
• General contractor (GC) — holds the prime contract and runs construction.
• Subcontractors — the trades (electrical, plumbing, etc.) that do specialized work.
• Suppliers and inspectors (the building department).

The order of work

Design → permits → site work → foundation → framing/structure → systems (mechanical, electrical, plumbing) → finishes → inspection → occupancy.

Each trade depends on the one before it — which is why schedule and coordination matter so much.

Going Deeper (Intermediate)

The sequence isn't random — it follows the critical path. Some tasks can slip without delaying the job (they have float); others delay everything the moment they slip. Foundation → framing → dry-in → rough-ins → inspections → insulation → drywall → finishes is the classic residential critical path, and inspections are hold points baked into it.

Key roles you'll coordinate with:

• GC / Superintendent — runs the site day to day.
• Project Manager — runs the budget, contracts, and submittals from the office.
• Foreman — runs your specific crew.
• Inspector (AHJ) — the Authority Having Jurisdiction; their sign-off unlocks the next phase.

Advanced / Pro-Level

Pros run the site with a few tools you should know by name:

• The schedule of values & lookahead — most supers run a 3-week lookahead so trades stage materials and manpower before they're needed.
• RFIs (Requests for Information) — the formal way to resolve a drawing question in writing so the answer is documented and someone owns it.
• Submittals — product data/samples approved before installation; installing before approval is at your own risk.
• Rough-in inspections are sequenced: you cannot cover work (insulate/drywall) until the framing, electrical, plumbing, and mechanical rough-ins each pass. Cover too early and you'll open the wall back up — on your dime.

The expensive mistake at this level isn't doing the work wrong; it's working out of sequence so another trade has to demo and redo theirs.

Practice Challenge

Drywall is scheduled Monday, but the electrical rough-in inspection hasn't happened and the HVAC ducts aren't insulated. What's the correct call, and who do you notify? (Answer: stop — do not cover. Notify the super/foreman; drywall can't proceed until rough-in inspections pass, or the walls get reopened.)

In Practice

Say the electrician shows up to rough-in wiring, but the framing isn't finished — there's nothing to attach boxes to, so the crew gets sent home and you've paid for a wasted trip. That's why sequence and scheduling matter: each trade depends on the one before it being ready.

Common Mistakes to Avoid

• Not knowing who runs the site (the super/foreman)
• Doing work out of sequence
• Failing to coordinate with the other trades

Takeaway: Know the players and the order of work — a building goes up in sequence, each trade depending on the last.
