Post-construction
Maintenance period / defects liability period
Track, triage, assign, fix, and close defects or warranty items reported after handover, while protecting records and client relationship.

What happens in this stage
- Maintain a DLP/maintenance defect log with date, location, photo, category, responsible trade, action, appointment, and close-out evidence.
- Separate urgent safety/water/electrical issues from cosmetic settlement or normal maintenance.
- Complete planned DLP inspection and process final retentions/release obligations according to contract.
Before work starts
- Confirm the latest issued-for-construction and consented documents for maintenance period / defects liability period are on site, including As-built drawings.
- Check Contract DLP/maintenance 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
Door sticking after handover
- 1Stop the affected maintenance period / defects liability period 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.
Minor plumbing leak
- 1Stop the affected maintenance period / defects liability period activity if continuing could hide defective work, create unsafe work, or move away from the consented design.

- 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.
Trade recall delay
- 1Stop the affected maintenance period / defects liability period activity if continuing could hide defective work, create unsafe work, or move away from the consented design.

Source / Where to check
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 — check the consented drawings, project specification, relevant NZ Standard, or council requirement.

Common inspections required
- DLP inspection
- Warranty inspection
- Close-out reinspection
Common risks
- Urgent defect not actioned
- Warranty voided by poor maintenance
- Poor record trail
- Trade recall delays
Common mistakes

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
