    Simple explanation

    Compare grids, levels, dimensions, wall types, openings, penetrations, drainage, foundations, structure, envelope, and service routes across disciplines.

    Technical context

    Coordinate this work against Architectural, Project specification, the current consent status, and the actual site condition. Confirm interfaces before releasing dependent work.

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

    Prerequisites

    • Architectural is current, approved for the intended use, and available to the people doing the work.
    • Project specification and relevant product information have been checked.
    • Access, responsibility, safety controls, preceding work and the design coordination workshop sequence are confirmed.

    Checks

    • Check the completed work against Architectural and Project specification.
    • Check specifically for: Discipline clash.
    • Avoid this known mistake: Starting drawings and specifications review without confirming the current documents and responsibility.

    Evidence to save

    • Wide, location-identifying and close-up photographs of the completed drawings and specifications review work before it is concealed.
    • Marked-up Architectural or a precise drawing/detail reference.
    • Design coordination workshop 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 Design coordination workshop and the required project evidence are complete or the authorised reviewer confirms what may proceed.

    Stop or escalate when

    • Discipline clash
    • Starting drawings and specifications review without confirming the current documents and responsibility
    • The current drawing, approval, competent reviewer or required evidence cannot be confirmed.

    Documents and records

    • Architectural
    • Project specification
    • 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 drawings and specifications review. 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

    Check schedules and specifications against drawing notes, consent conditions, selections, product data, and consultant reports.

    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

  • Compare grids, levels, dimensions, wall types, openings, penetrations, drainage, foundations, structure, envelope, and service routes across disciplines.
  • Check schedules and specifications against drawing notes, consent conditions, selections, product data, and consultant reports.
  • Record every gap, clash, ambiguity, missing dimension, unpriced selection, and constructability concern in a coordinated RFI list.

Before work starts

  • Confirm the latest issued-for-construction and consented documents for drawings and specifications review are on site, including Architectural.
  • Check Project specification, 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

Drawings and specifications review information is incomplete or conflicting
  1. 1Stop the affected drawings and specifications review 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.

Verification

Source / where to check

Use current official information and the controlled documents for the actual project.

Consented drawings and specifications

The issued consent drawings, stamped specifications, engineering drawings, RFIs, minor variations, and amendments control the specific project.

Use when a site change may require a minor variation or amendment before work continues.

Manufacturer specification

Use the exact current installation manual, warranty requirements, BRANZ/Appraisal information where applicable, and product data sheet for the product on site.

Consented drawings and specifications

The issued consent drawings, stamped specifications, engineering drawings, RFIs, minor variations, and amendments control the specific project.

Manufacturer specification

Use the exact current installation manual, warranty requirements, BRANZ/Appraisal information where applicable, and product data sheet for the product on site.

Insufficient data to verify

Insufficient data to verify — confirm against the current consented drawings, specifications, Auckland Council requirements, Auckland Unitary Plan, NZ Building Code, relevant NZ Standard, consultant advice, manufacturer instructions, insurance broker, insurer, lender, lawyer, accountant or project contract.

Project-specific consented documents and professional advice override generic guidance.

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
