How to execute this stage

Micro-stage control plan

Work through each applicable step in order. A hold point means pause the dependent decision or work until the stated evidence and authorised review are complete.

3 structured steps
  1. 01Obtain current records, locate and mark services, verify ownership and live status, and confirm provider/qualified-trade requirementsLevel 2 · Ground and substructure
    TaskCheckHold pointEvidenceRecordNext action

    Simple explanation

    Obtain current records, locate and mark services, verify ownership and live status, and confirm provider/qualified-trade requirements.

    Technical context

    Coordinate this work against Existing service plan, Provider requirements, the current consent status, and the actual site condition. Confirm interfaces before releasing dependent work.

    Why it matters: The main recorded risk is: Electric shock. A missed check can create rework, delay, hidden defects, an inspection failure, or a departure from approved project documents.

    Prerequisites

    • Existing service plan is current, approved for the intended use, and available to the people doing the work.
    • Provider requirements and relevant product information have been checked.
    • Access, responsibility, safety controls, preceding work and the qualified-trade isolation check sequence are confirmed.

    Checks

    • Check the completed work against Existing service plan and Provider requirements.
    • Check specifically for: Electric shock.
    • Avoid this known mistake: Starting service disconnections without confirming the current documents and responsibility.

    Evidence to save

    • Wide, location-identifying and close-up photographs of the completed service disconnections work before it is concealed.
    • Marked-up Existing service plan or a precise drawing/detail reference.
    • Qualified-trade isolation check result, consultant record, trade QA record or written not-applicable reason.

    Hold point

    Do not cover, backfill, load, connect, certify or release the next activity until Qualified-trade isolation check and the required project evidence are complete or the authorised reviewer confirms what may proceed.

    Stop or escalate when

    • Electric shock
    • Starting service disconnections without confirming the current documents and responsibility
    • The current drawing, approval, competent reviewer or required evidence cannot be confirmed.

    Documents and records

    • Existing service plan
    • Provider requirements
    • Current RFI/site-instruction/change record
    • Inspection and evidence register
    Cost effect
    Rectification, reinspection, delay, damaged follow-on work, access loss and changed scope can increase the cost of service disconnections. Record the cause and obtain written pricing before approving a commercial change.
    Programme effect
    This activity controls the release of dependent work. Update the lookahead programme and notify affected trades if the hold point, information, inspection or evidence is not ready.

    Next action

    Schedule lawful disconnection, meter removal, capping, temporary supply, and any retained-service protection before demolition or excavation.

    Applicability: Apply when this work package is included in the current project scope. Confirm project-specific consent, contract, design, site and authority requirements.

    Use the current consented/issued project documents and competent site review. BuildPath does not approve work.

What happens in this stage

  • Obtain current records, locate and mark services, verify ownership and live status, and confirm provider/qualified-trade requirements.
  • Schedule lawful disconnection, meter removal, capping, temporary supply, and any retained-service protection before demolition or excavation.
  • Keep certificates, provider confirmations, photos, as-built locations, and tags showing what is live, dead, capped, temporary, or retained.

Before work starts

  • Confirm the latest issued-for-construction and consented documents for service disconnections are on site, including Existing service plan.
  • Check Provider requirements, approved product data, RFIs, minor variations, and amendment status before work starts.
  • Confirm the subcontractor understands the scope, hold points, access, protection requirements, H&S controls, and quality evidence required.
  • Check the programme sequence so this stage does not start before earlier work, inspections, testing, or concealed-work photos are complete.
  • Confirm materials delivered to site match the specification, are dry/undamaged, and are stored according to manufacturer instructions.

During the work

  • Walk the work face early, mid-shift, and before close-up. Compare actual work with the consented drawings, specification, and manufacturer details.
  • Check set-out, levels, falls, clearances, penetrations, fixings, bracing, waterproofing, or protection points that will be difficult to see later.
  • Ask trades to show their own quality checks rather than only saying the work is complete.
  • Keep weather, site condition, delivery, delay, inspection, RFI, variation, and safety notes in the daily report.
  • Photograph any work before it is covered, backfilled, lined, clad, tiled, painted, or otherwise hidden.

After the work

  • Complete a close-out walk with the subcontractor and mark defects immediately while access is still available.
  • Confirm required inspection bookings, council results, producer statements, LBP Records of Work, warranties, test certificates, or installer declarations are obtained.
  • Update as-built notes where service routes, drainage, fixings, penetrations, or dimensions differ from the design.
  • Confirm the area is protected from weather, other trades, impact damage, contamination, or premature loading.
  • Update the lookahead programme and tell affected trades what is ready, what is blocked, and what must not be covered.

Common problems and step-by-step solutions

Service disconnections information is incomplete or conflicting
  1. 1Stop the affected service disconnections activity if continuing could hide defective work, create unsafe work, or move away from the consented design.
  2. 2Photograph the condition from wide, medium, and close-up angles. Include a tape, level, datum mark, gridline, or drawing reference where useful.
  3. 3Check the latest consented architectural, structural, civil, services, and specification documents before giving an instruction.
  4. 4Ask the subcontractor to explain the cause, proposed fix, timing impact, and whether the fix changes consented work.
  5. 5Escalate to the builder/project manager, designer, engineer, council inspector, or client when the fix affects structure, weathertightness, drainage, H1, fire/safety, cost, programme, or consent.
  6. 6Record the decision, responsible person, drawing/RFI/variation reference, photos, and follow-up inspection in the daily report.

Questions to ask the subcontractor

  • Which drawing, detail, or manufacturer instruction are you working from?
  • What needs to be checked before this is covered or handed to the next trade?
  • What could stop you today: weather, access, materials, information, inspections, or other trades?
  • Does anything on site differ from the drawings or specification?
  • What evidence will you provide for the quality file and CCC file?

Red flags to stop work

  • Work differs from consented drawings or specification and no approved variation/RFI exists
  • A structural, weathertightness, waterproofing, drainage, fire/safety, or H1 detail is unclear
  • The trade wants to cover work before inspection, testing, or photos are complete
  • Specified materials are missing, substituted, damaged, wet, expired, or installed outside manufacturer instructions
  • A safety control is missing for excavation, heights, plant movement, electrical work, asbestos, silica, or public protection

What to record in the daily report

  • Exact location and quantity of work completed
  • Trade headcount, company names, plant used, deliveries, and material batch/product details
  • Weather, site conditions, delays, instructions received, RFIs raised, and inspections booked/passed/failed
  • Photos taken before cover-up and any defects or non-conformances found
  • Next-day lookahead, blockers, and who is responsible for each action
