Builder Pre Start Checklist for Refurbishment Work

The demolition crew arrives, but furniture and appliances still fill the first room. A builder pre start checklist stops that wasted morning by releasing only the rooms and tasks that are ready.

Treat the construction pre-start meeting as a permission-to-start gate. Not a general introduction. Settle authority, scope, access, approvals and trade hand-offs before you commit labour, subcontractors or materials.

Use the builder pre start checklist as a release gate

Do not approve the whole refurbishment with one vague “ready to start”. Release named rooms and tasks.

Use three decisions:

• Go: everything needed for the named task is ready.
• Conditional go: open items remain, but they do not block the released task.
• No-go: an unresolved item prevents the task from starting.

A conditional go still needs control. Give each open item a named owner, a due point, the task it affects and the evidence needed to clear it.

Ask one blunt question for every open item: what work cannot start until this is settled?

An undecided paint colour may not block strip-out. An unknown kitchen layout can block service positions. Record the difference instead of treating both as general client decisions.

Apply the decision by room and trade. The bathroom can be clear for protection and strip-out while electrical work remains blocked by an unapproved layout. The kitchen can stay no-go while work starts elsewhere.

Write the release decision at the top of the record. Discussion is not permission to mobilise.

Name who decides and who delivers

Bring people who can make a decision or complete an action. Observers do not clear blockers.

Name the client representative who can approve selections, access, shutdowns, scope changes and variations. If a landlord, designer or other owner can overrule that person, settle the approval route before the meeting ends.

Bring the supervisor who will run the site. Add affected tradespeople when their work depends on a disputed dimension, selection, inspection or hand-off. They do not need every client conversation. They need the decisions that control their work.

For each action, record:

• The person making the decision
• The person completing the task
• The person checking it
• The trade or task waiting for the result
• The evidence that closes the action

Do not write “client”, “office” or “electrician” as the owner. Write a person’s name. Read the action back and get agreement.

If nobody present can approve a decision needed for the first task, that task stays blocked.

Close UK approval, regulated-work and safety gates

Do not use one general licence box copied from another market. Close each regulated-work question separately and attach the answer to the room or task it can block.

• For gas work, check the named installer with the Gas Safe Register (opens in a new tab). Save the check with the work instruction.
• For water fittings work, use Ofwat (opens in a new tab) to identify the statutory water undertaker for the property. Record the named installer, the route given by that undertaker and any evidence or inspection hold point required before covering the work.
• For notifiable electrical work in England, record whether the installer can self-certify through a competent person scheme (opens in a new tab) or whether building control must handle the route. The guide to notifying electrical work in England answers the England question only.
• For electrical work in Wales, record the self-certification or building control route against the Welsh building regulations (opens in a new tab). Enter any inspection hold point and attach the completion evidence.
• For electrical work in Scotland, ask the local-authority verifier whether the work affects the building warrant or inspection route. Record the answer under the Scottish building standards system (opens in a new tab); do not use an England Part P instruction.
• For electrical work in Northern Ireland, record the approval and inspection route with the council building control service identified through nidirect (opens in a new tab). Attach the evidence to the electrical task.
• For building work in England, record the approval route and inspection stages with building control (opens in a new tab).
• For building work in Wales, record the approval route and inspection stages under the Welsh building regulations (opens in a new tab).
• For building work in Scotland, record the local-authority verifier, warrant route and inspection hold points under the Scottish building standards system (opens in a new tab).
• For building work in Northern Ireland, record the responsible council building control service, application route and inspection hold points through nidirect (opens in a new tab).
• For VAT or CIS, record the treatment used for the job and its subcontractors after checking with HMRC (opens in a new tab).

The builder does not need to guess the ruling during the meeting. The builder does need to identify the question, send it to the correct body and keep the affected work blocked until the answer is recorded.

Block disturbance until the safety record is ready

Before intrusive work starts, record the dutyholders for the project and the person controlling the site. Put the construction phase plan in the start pack before site set-up begins.

Write controls for the actual property and task. Cover access, service isolation, dust, structural stability, work at height, welfare and emergencies. For work in Great Britain, check workplace health and safety duties with the Health and Safety Executive (opens in a new tab). For work in Northern Ireland, use the Health and Safety Executive for Northern Ireland (opens in a new tab).

Obtain asbestos information that covers the parts of the building to be disturbed. If the information is missing, out of date or does not cover the work area, block drilling, cutting, opening and strip-out there. Record who must provide the missing information and what evidence will release the task.

Put every required inspection, assessment or clearance into the programme. Keep the next trade blocked when its work would hide the area that still needs to be checked.

Lock the room-by-room scope before ordering

Walk the property with the accepted quote, current drawings, specifications, selections and exclusions. Match the documents to the actual rooms.

For each room, point to what stays, what goes and what gets altered. Confirm dimensions that control ordering. Record the product, finish, quantity, supplier and person responsible for ordering it.

If a product or dimension is not settled, block the purchase and any installation that depends on it. Do not let an unconfirmed selection become an urgent site decision after labour has arrived.

Check the trade boundaries as you go. State who:

• Opens walls, floors and ceilings
• Moves each service
• Supplies fittings and fixings
• Provides backing or repairs the substrate
• Seals penetrations
• Tests the finished work
• Makes good each surface

“By others” is not an instruction. Name the trade and describe the finish they must leave for the next person.

Remove contradictions before release. If the quote excludes one ceiling but the drawing shows work there, stop. One room cannot have two current instructions.

Write a hidden-condition stop rule

List the assumptions behind concealed walls, ceilings, floors, pipework and wiring. Tell the supervisor what to do when the actual condition differs:

1. Stop the affected work.
2. Photograph the condition.
3. Describe the extra or changed work.
4. Record the price and programme effect.
5. Get written approval from the named person.
6. Continue only after approval.

Use the guide to writing a clear quote to write the added work as a variation with its scope, labour, materials and exclusions.

Worked example: the Oak Street chasing exclusion

All figures in this example are sample currency units, not a rate card.

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

Extra cable and chasing were needed on site. The electrician stopped and obtained approval for a 160 variation. Invoice INV-1847 was then 1,265.

The important pre-start facts were the chasing exclusion, the stop rule and the person authorised to approve the variation. Without those controls, the electrician would have to guess whether to continue.

Walk the property and prove renovation site readiness

Do the readiness walk at the property with the supervisor. Old photographs will not show the van blocking the unloading point, the new furniture in the first room or the materials filling the only dry storage area.

Walk from the street to every released room. Test the route a tradesperson or delivery driver will use.

Record:

• Parking and unloading arrangements
• Keys, gates, alarms and entry codes
• The person keeping access clear
• Dry and secure material storage
• Tool storage
• Waste storage and removal routes
• Power and water points available to the crew
• Welfare arrangements
• Working-hour or noise restrictions affecting access

Do not release a delivery because the materials have been ordered. Release it when the dimensions are confirmed, the unloading route is clear and the storage area is ready. Moving materials twice burns labour and invites damage.

Mark occupied and protected areas

Draw the boundary between the building site and the occupied home. Mark occupied rooms, no-entry areas, dust-control lines, temporary partitions and protected routes.

Name who moves furniture, appliances, artwork and personal belongings. If the client must clear a room, give that task a due point and keep strip-out blocked until it is done.

Record pets, children, alarms and cameras where they affect entry or working arrangements. Photograph existing damage and the surfaces the crew must preserve. Take a wide photograph for location and a close photograph for condition. Label both by room.

Locate available service isolation points. Name the tradesperson responsible for each shutdown and restart. Do not let one trade assume another trade has isolated or tested a service.

Renovation site readiness is proved by the room condition, access record, protection plan and closed client tasks. A promise that the property “will be ready” is not proof.

Build the programme around hand-offs and hold points

A date does not make a task ready. Write what must be complete before each trade arrives.

For every activity, record:

• The room and task
• The preceding work
• The required drawing or selection
• The inspection or check that must be complete
• The condition the next trade needs
• The person releasing the task

Put strip-out, structural work, first fix, inspections, closing, finishes, commissioning and handover in working order. Keep work visible where a required check depends on seeing it.

Treat client and third-party tasks as real programme activities. A client-supplied appliance, utility action or design decision can block a room as directly as unfinished building work.

Send each subcontractor the arrival condition. If the tiler needs a sound, prepared substrate, write that condition into the instruction. Do not book the tiler against a date while preparation remains open.

Set cost tracking controls before mobilisation

Tie every commitment back to the accepted scope. A purchase order or subcontract instruction should name the job, room, task and included work. It should not say only “materials” or “refurbishment labour”.

Use the same cost headings in the estimate, purchase orders, labour records and finished-job review. Keep the buckets plain:

• Labour
• Materials
• Plant
• Waste
• Subcontract work

Add room or work-package references where they help you trace a cost. Consistent headings let you compare the priced work with what the job consumed.

State who can approve a variation. Give the crew one instruction: if the agreed scope changes, stop the affected task, record the change and get written approval before continuing.

Confirm the quote reference, job reference, stage-payment references and VAT treatment used in the paperwork. If retention forms part of the agreed payment terms, set up the record before the first invoice rather than trying to rebuild it at close-out. The builder retention invoice guide explains how to keep the final balance tied to the job record.

Do not treat cost tracking as an office clean-up exercise. Set the codes before timesheets, supplier invoices and subcontract claims start arriving.

Issue one controlled builder mobilisation checklist and start pack

Give one person control of the current pack. Keep a register showing each document, its revision, who issued it and who received it.

Remove superseded drawings and schedules from the active pack. The supervisor having one revision while the electrician has another is a no-go, especially when the versions show different fixture positions.

Include only what controls the released work:

• Accepted scope and exclusions
• Current drawings and specifications
• Approved selections
• Contacts and decision authority
• Programme and hold points
• Access, storage and protection instructions
• Compliance evidence needed for the released tasks
• Existing-condition photographs
• Variation instruction
• Cost and payment references
• Open-item register

Send each trade the pages needed for its work. Do not make a subcontractor hunt through the entire sales file for the one current drawing.

Use this copy-ready room-release sheet:

Turn each approved room or task into a direct instruction. The guide to issuing released work as a work order shows the fields needed to carry scope, site contact and start conditions to the supervisor.

Release the first task and open the site record

On the first morning, the supervisor should check the released room, current document revision and first trade against the builder pre start checklist. Photograph the starting condition before anything is moved or disturbed.

Open the first builder daily log for the refurbishment. Record the people on site, conditions found, released work and any blocker that remains open.

If the crew finds a recorded blocker still unresolved, stop the affected start. Do not let attendance turn a no-go into accidental approval.
