Builder Pre Start Checklist: Release Rooms Before Mobilisation

The strip-out crew arrives, but the hallway is blocked and the vanity is still full. A builder pre start checklist prevents that wasted dispatch by releasing only the rooms and tasks that are ready.

Treat the construction pre-start meeting as a release gate. Check the accepted scope, decision-makers, approvals, access, protection and trade hand-offs. Then tell the supervisor exactly what can start.

Use the builder pre start checklist as a release gate

A meeting date does not make a room ready. Neither does a client saying the house is clear.

Give each room and task one status:

• Go: the task can start without waiting for another action.
• Conditional go: the task can start, but a later task remains blocked.
• No-go: labour, materials or approvals are missing for that task.

Apply the status to the task, not just the room. A bathroom can be ready for floor protection and strip-out while remaining blocked for plumbing rough-in or tiling.

An unfinished tile selection may not stop demolition. It should stop the tile order. A pending inspection may not stop work in another room. It should stop the work that would conceal the inspection point.

Use the builder pre start checklist to record what has actually been released. Do not use a general note such as “site ready”. Write the room, the task and the status.

A conditional go also needs a boundary. State what can proceed, what cannot proceed and what will close the remaining action. Without that boundary, the crew will make its own decision on site.

Meeting attendance is not permission to begin. The release status is the permission.

Put decision-makers in the construction pre-start meeting

Invite people who can make decisions or complete actions. Leave spectators out.

The builder or supervisor should control the release register. The client should nominate the person authorised to approve selections, access arrangements, service shutdowns and variations. A designer or consultant should attend where an unresolved drawing or specification controls the work.

Bring a subbie when their measurement, service route or incoming work condition is disputed. You do not need every trade at every meeting.

Record the authority held by each attendee. A family member who can open the door may not have authority to approve changed work. A property manager may control access but not product selections.

For each open action, write:

• The room and task waiting on the action
• The decision or work required
• The person responsible
• The due point before the dependent task
• The proof needed to close it
• The person who will check that proof

Use names. “Client”, “office” and “plumber” are not clear enough when dispatch is waiting.

Proof should match the action. A photograph may prove that hallway furniture has been removed. A marked-up drawing may prove a layout decision. A supplier confirmation may prove that a customer-supplied fixture will be on site. A supervisor inspection may be needed where the work condition cannot be judged from a photograph.

If nobody present can approve a decision, keep the affected task closed. Do not turn a missing decision-maker into an instruction for the crew to sort out later.

Reconcile the accepted scope before discussing start dates

Put the current scope records on the table before discussing mobilisation. Use the accepted quote or contract, current drawings, approved selections, exclusions and approved variations.

These documents must describe the same work. If a drawing shows a relocated doorway but the accepted quote and framing scope omit the relocation, stop. Decide whether the doorway is included before booking demolition or framing.

Walk the documents room by room. Mark:

• What stays
• What gets removed
• What gets altered
• Which surfaces may be opened
• Which finishes must be protected
• Who supplies each fixture and finish
• What the accepted scope excludes
• Which approved variations have changed the work

Avoid broad task names. “Renovate bathroom” gives the crew no boundary. “Strip bathroom after access protection and client contents removal” states what can begin and what must happen first.

Check customer-supplied items before dependent work

List every fixture, appliance or finish supplied by the client. Record its specification, who checks it, where it will be stored and when it must reach the site.

Do not treat “client supplying” as a complete instruction. A vanity can arrive with the wrong dimensions. Tiles can arrive without an approved finish. A fitting can be on site but damaged or incomplete.

Check customer-supplied items before releasing the task that depends on them. If the item is not required for strip-out, keep strip-out open and hold the later installation task.

Draw the line between subbie scopes

Name where one subbie finishes and the next begins. State who opens the surface, installs backing, alters the service, repairs the substrate, seals penetrations and completes the make-good work.

“By others” is not a hand-off. Replace it with a named scope owner.

Use a subbie scope comparison before the renovation to find overlaps, exclusions and missing make-good work before the meeting. Settle the gap while the quote and drawings are in front of you.

Build an Australian authority map for the job

Do not put licences, approvals and safety under one box marked “compliance”. Different bodies answer different questions.

Create an authority map for the property. Record the question, the responsible body, the task blocked by the answer and the proof kept with the job.

Identify the regulator and licence class that apply to the work and the property before relying on an answer. In NSW, use NSW Fair Trading (opens in a new tab) only when it is the regulator for that work. In Queensland, use the Queensland Building and Construction Commission (opens in a new tab) only for licence and home building contract questions within its scope. In Victoria, use Energy Safe Victoria (opens in a new tab) only for electrical and gas safety licensing questions within its scope.

Do not carry an answer from one state into another. Do not ask a licensing regulator to decide a workplace safety question.

For a NSW workplace safety question, contact SafeWork NSW (opens in a new tab). For a NSW workers’ compensation question, contact the State Insurance Regulatory Authority (opens in a new tab). Use the equivalent responsible body when the property is elsewhere.

Do not guess a current rule, fee, threshold or deadline. Ask the official body responsible for the question and write down the answer. Keep the affected task at no-go until the required record is on file.

Test renovation site readiness from the street to the work face

Walk the route the crew will actually use. Start at the street. Finish at the work face.

Check parking, gates, steps, side access, stairs, halls and door openings. Walk the delivery route and the waste-removal route. A room can be empty while the path to it remains blocked.

The strip-out crew should not arrive to find vanity contents, hallway furniture or wall-mounted items still in the access route. Name who will remove each item and what proves the route is clear.

Check occupied-home hazards before strip-out

Before releasing strip-out, check for known or suspected hazardous materials, live services and unstable walls, ceilings, floors or fixtures. Record any assessment or control document required by the state or territory WHS regulator.

Name the responsible person who will assess the condition, isolate the hazard or confirm the control. Keep the affected room and task at no-go until that person records the clearance.

Clear and protect the occupied home

Mark the boundary between the work area and the occupied part of the home. Identify protected paths, no-entry rooms, dust-control points, temporary partitions and retained finishes.

Photograph the existing condition before moving materials through the property. Take a wide photograph that identifies the room and a close photograph of any existing damage or finish that needs protection.

A photograph records condition. It does not add work to the accepted scope.

Record pets, children, occupants, cameras, keys, alarms and daily lock-up arrangements where they affect access. Name the person who opens the property and the person who secures it after the crew leaves.

Locate service isolation points that affect the released work. Assign shutdown, testing and restart work only to the person qualified and authorised to perform it. Tell occupants what will be unavailable and who will confirm restoration.

Check deliveries and storage before releasing orders

Do not release a delivery merely because the supplier has stock ready.

Check the selected product, finish, dimensions, unloading route and storage location. Confirm that the storage area is dry, secure and clear of the work face.

Tiles sitting at the property do not prove readiness if the finish is unapproved or there is nowhere safe to store them. Keep the order or installation task blocked until the missing condition is closed.

Renovation site readiness means the route works, the named task has a clear work face and each open action has an owner.

Build the builder mobilisation checklist around dependencies

Mobilise labour for released tasks only. Do not send a full crew because the overall project start date has arrived.

For each room and task, state the incoming condition. Tell the subbie what must already be complete when they arrive.

A tiler may need a prepared substrate, completed checks and an approved tile layout. A painter may need repaired surfaces, an approved colour and a dry room. An electrician may need a confirmed fitting layout and an accessible cable route.

Where bathroom tiling is involved, use the waterproofing and substrate record before tiling to keep the required check ahead of work that would conceal it.

Release each resource against a named dependency:

• Labour: released room and task
• Subbie: required preceding work and incoming condition
• Materials: approved selection, checked dimensions and storage location
• Equipment: confirmed access and work area
• Inspection: completed before covering the work
• Site facilities: check worker amenities, temporary power and water, the waste location, dry and secure material storage, first aid and clear emergency access before releasing the crew

A program of works gives sequence and timing. It does not prove readiness. Add release status to the dispatch instruction so the crew knows where it may work.

Do not send the entire drawing pack without direction. Mark the current drawing set and the sheets controlling the released task. Withdraw superseded instructions from the mobilisation pack.

Stop changed work and write a variation

Opening a wall, floor or ceiling can expose a condition that was not in the accepted scope. Physical access does not make the extra work included.

Stop the affected task. Photograph the condition and record the exact room and location. Name the task stopped, the exclusion or scope boundary that applies, the variation reference, the written approval and the revised release status.

Describe the work needed, its price effect and its effect on the program of works. Send it to the authorised client representative and get written approval before continuing.

Use the clear quote writing guide to describe added labour, materials, subbie work and exclusions. Call the approved change a variation.

Worked example: Oak Street access did not expand the scope

All figures below are sample currency units. They are not a rate card.

R. Chen accepted quote Q-1847 for 1,105 at 14 Oak Street. The electrical scope covered a bathroom exhaust fan, 150mm and ducted through the roof, plus four LED downlights. The ceiling was lined, and the quote excluded chasing.

The bathroom could be clear for access while chasing remained outside the scope. Extra cable and chasing were approved on site as a 160 variation. Invoice INV-1847 was then 1,265.

That variation had to be approved before the extra work continued. For the trade-level record, use the electrical variation process for renovation jobs to capture the changed condition, approval and revised invoice line.

Issue a first-day mobilisation sheet to the supervisor

The supervisor does not need an unmarked bundle of project documents. Give them a short sheet showing released rooms, blocked tasks, open actions, contacts and current instructions.

Copy this builder pre start checklist template into the job record. Complete the job header once, then add one register row for each room and task.

Job and document-control header

Repeatable room and task register

Attach the drawing revisions that control released work. Add site contacts, access instructions, service arrangements and required site records. Mark superseded documents so they cannot be mistaken for current instructions.

Send the sheet to the supervisor and affected subbies before dispatch. Record who received the issue and replace it when a drawing, variation or release status changes.

Once work starts, use the builder pre start checklist as the opening record and keep the renovation site record current. Record completed actions, changed conditions, deliveries, instructions and release decisions against the job.
