Interior
Internal linings
Fix plasterboard, bracing linings, wet-area linings, fire/acoustic linings where specified, and stopping systems only after pre-line checks are complete.
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.
01Confirm framing, services, insulation, bracing, moisture, and inspection status before lining startsLevel 2 · Interior
TaskCheckHold pointEvidenceRecordNext actionSimple explanation
Confirm framing, services, insulation, bracing, moisture, and inspection status before lining starts.
Technical context
Coordinate this work against Wall lining plan, Plasterboard manufacturer manual, the current consent status, and the actual site condition. Confirm interfaces before releasing dependent work.
Why it matters: The main recorded risk is: Bracing not fixed correctly. A missed check can create rework, delay, hidden defects, an inspection failure, or a departure from approved project documents.
Prerequisites
- Wall lining plan is current, approved for the intended use, and available to the people doing the work.
- Plasterboard manufacturer manual and relevant product information have been checked.
- Access, responsibility, safety controls, preceding work and the pre-line inspection sequence are confirmed.
Checks
- Check the completed work against Wall lining plan and Plasterboard manufacturer manual.
- Check specifically for: Bracing not fixed correctly.
- Avoid this known mistake: Lining before inspection passed.
Evidence to save
- Wide, location-identifying and close-up photographs of the completed internal linings work before it is concealed.
- Marked-up Wall lining plan or a precise drawing/detail reference.
- Pre-line inspection 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 Pre-line inspection and the required project evidence are complete or the authorised reviewer confirms what may proceed.
Stop or escalate when
- Bracing not fixed correctly
- Lining before inspection passed
- The current drawing, approval, competent reviewer or required evidence cannot be confirmed.
Documents and records
- Wall lining plan
- Plasterboard manufacturer manual
- 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 internal linings. 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 sheet type, thickness, bracing/fixing pattern, wet-area board locations, control joints, and penetrations.

Open the related Workspace control →What happens in this stage
- Confirm framing, services, insulation, bracing, moisture, and inspection status before lining starts.
- Check sheet type, thickness, bracing/fixing pattern, wet-area board locations, control joints, and penetrations.
- Record concealed evidence and protect finished surfaces.
Before work starts
- Confirm the latest issued-for-construction and consented documents for internal linings are on site, including Wall lining plan.
- Check Plasterboard manufacturer manual, 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
Pre-line issue
- 1Stop the affected internal linings activity if continuing could hide defective work, create unsafe work, or move away from the consented design.
- 2Photograph the condition from wide, medium, and close-up angles. Include a tape, level, datum mark, gridline, or drawing reference where useful.
- 3Check the latest consented architectural, structural, civil, services, and specification documents before giving an instruction.
- 4Ask the subcontractor to explain the cause, proposed fix, timing impact, and whether the fix changes consented work.
- 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.
- 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.
Check structure requirements, B1/AS1, Verification Methods, structural engineer design, bracing, foundations, wind, earthquake, and consented structural drawings.
Check wet-area surfaces, ventilation, waterproofing details, and manufacturer systems against consented documents.
Use the exact current installation manual, warranty requirements, BRANZ/Appraisal information where applicable, and product data sheet for the product on site.
The issued consent drawings, stamped specifications, engineering drawings, RFIs, minor variations, and amendments control the specific project.
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 — 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.

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
