The handover is the last thing you do on a project and one of the most important. A smooth handover leaves the client confident in their new building and confident in you. A botched handover, with missing documentation, unresolved defects, and confused operators, can undo months of good work and destroy a client relationship. Here is a comprehensive checklist to make sure you get it right.
Pre-Handover Preparation
Handover preparation should start months before practical completion, not weeks. The biggest handover failures happen when documentation is left to the last minute.
- Start collecting O&M information from subcontractors early: Do not wait until they have left site. Make O&M submissions a condition of interim payments. Chase them relentlessly. Getting O&M information from a subcontractor who has moved on to another project is like getting blood from a stone.
- Maintain a handover tracker: List every document, certificate, and piece of information that needs to be in the handover pack. Track its status (outstanding, received, reviewed, approved). Review this tracker weekly in the last three months.
- Progressive snagging: Do not save all snagging for the end. Snag areas as they are completed. If the ground floor is finished in month 8, snag it in month 8. This spreads the workload and gives subcontractors time to return and fix issues while they are still on site.
- Arrange training early: Book training sessions for the client's building operators well in advance. Training on M&E systems, fire alarm operation, BMS systems, and security systems needs to happen before the building is handed over, not after.
Documentation Checklist
The following documents should be compiled and ready for handover:
Statutory Certificates
- Building control completion certificate (or final inspection confirmation)
- Fire safety certificate / fire risk assessment for the completed building
- Energy Performance Certificate (EPC)
- Electrical installation certificates (BS 7671)
- Gas safety certificates
- Pressure systems certificates (if applicable)
- Lift commissioning certificates and LOLER reports
- Water hygiene risk assessment and Legionella testing results
Design and Construction Records
- As-built drawings (all disciplines: architectural, structural, M&E, drainage)
- Specification and any amendments
- Test and commissioning records for all M&E systems
- Concrete cube test results and structural test certificates
- Welding inspection records
- Material certificates and test reports
- BREEAM documentation (if applicable)
Operation and Maintenance
- O&M manuals for all installed systems (HVAC, electrical, plumbing, fire, security, lifts, BMS)
- Equipment schedules with manufacturer details, model numbers, and serial numbers
- Spare parts lists and recommended stock levels
- Maintenance schedules for all systems
- Warranty information and guarantee certificates
- Contact details for all specialist maintenance contractors
CDM Health and Safety File
- As-built information about hidden services and structural elements
- Information about hazardous materials used in construction
- Design assumptions and loading information
- Details of temporary works that might affect future work
- Information needed for safe cleaning, maintenance, and future modifications
Snagging and Defects
A thorough snagging process protects both you and the client.
- Internal pre-snag: Do your own snagging inspection before the client does theirs. Walk every room, corridor, and service area. Check finishes, fittings, door operation, window operation, paint quality, floor finishes, and ceiling grids. It is far better to find and fix issues before the client's representative creates a 500-item list.
- Systematic approach: Snag room by room, using a consistent methodology. Start at the door and work clockwise. Check floor, walls, ceiling, fittings, and services in each room. Use a structured snag list format.
- Photographic evidence: Photograph each defect and photograph the remediation. This provides evidence that the work was done and protects you against claims that defects were not addressed.
- Prioritise: Distinguish between defects that prevent practical completion (the lift does not work, a room is not watertight) and minor cosmetic issues that can be addressed during the defects liability period. Do not let minor snagging items delay practical completion if the building is otherwise usable.
- Track to closure: Every snag item needs a responsible party, a target date, and a status. Review the list daily during the snagging period. Chase subcontractors who are not responding.
Testing and Commissioning
All building systems must be tested and commissioned before handover:
- HVAC systems: Air flow measurements, temperature control verification, noise levels, BMS integration testing
- Electrical systems: Circuit testing, RCD testing, emergency lighting duration test, power quality measurements
- Fire systems: Full fire alarm test (every device), sprinkler flow test, smoke ventilation test, fire door operation, emergency voice communication test
- Plumbing and drainage: Water pressure tests, drainage flow tests, hot water temperature checks, TMV calibration
- Lifts: Full commissioning by the lift installer, witnessed by the lift consultant. LOLER thorough examination before handover.
- Security systems: CCTV coverage verification, access control testing, intruder alarm testing
- Integrated systems test: Test systems working together. Does the fire alarm trigger the smoke ventilation? Does it recall the lifts? Does it release the access control doors? These interfaces are where problems often hide.
Training and Demonstrations
The client's building operators need to know how to operate and maintain every system. Training should be:
- Scheduled in advance: Book training sessions at least 4 weeks before handover. Coordinate with subcontractors and specialist suppliers.
- Hands-on: Operators should physically operate the systems during training, not just watch a presentation. Show them how to reset the fire alarm, adjust the BMS set points, and respond to common faults.
- Recorded: Video record training sessions (with the trainer's consent) so the client has a reference they can revisit. Provide written training summaries alongside the O&M manuals.
- Signed off: Get the client's representatives to sign training attendance records confirming they have received training. This protects you if the client later claims they were not shown how to operate something.
The Handover Meeting
The formal handover meeting is where you transfer responsibility for the building. It should include:
- Walk-through of the building with the client's team
- Handover of all keys, access cards, and security codes
- Handover of all documentation (physical and digital)
- Review of outstanding snagging items and agreed programme for completion
- Confirmation of the defects liability period and the process for reporting defects
- Emergency contact details for the contractor during the defects period
- Confirmation that all training has been completed
- Formal sign-off (practical completion certificate)
Post-Handover Responsibilities
Your responsibilities do not end at handover:
- Defects liability period: Typically 12 months under JCT contracts. You must return to site and rectify any defects that emerge during this period. Respond promptly to defect reports -- the client's patience has a finite life.
- Season commissioning: Some M&E systems need to be recommissioned when the seasons change. A heating system commissioned in summer may need adjustment when winter arrives. Agree a schedule for seasonal commissioning with the client.
- Making good: At the end of the defects period, carry out a final inspection with the client, address any remaining issues, and obtain the certificate of making good.
