A building is ready for use when its owner has the information needed to operate, maintain and care for it.
At project handover, attention naturally goes to the finished spaces, the final cleaning and the moment the keys are received. The documents handed over at the same time deserve equal attention. They explain what was built, where important services are located, how equipment should be used and whom to contact when a problem arises.
For a design–build project, a proper handover brings together information from the design team, site team, specialist contractors, suppliers and the people who carried out the work. The exact documents vary by project, but the following checklist gives owners a practical starting point.
1. Approvals and completion records
The owner should receive copies of the approved plans, building permit, completion documents and occupancy certificate, as applicable to the project. Other relevant approvals or clearances should also be included where required.
These records may be needed later for property records, financing, insurance, alterations or a future sale.
2. As-built drawings
Approved drawings show what was intended. As-built drawings record what was actually constructed, including changes made during execution. Depending on the scope, the handover set may include architectural, structural, electrical, plumbing, drainage, air-conditioning and other service drawings.
These records are especially valuable when a concealed pipe must be repaired, an electrical circuit must be traced or the building is renovated years later. Without reliable drawings, even a small change can involve unnecessary breaking and guesswork.
3. Test and commissioning reports
Relevant records may include electrical test reports, plumbing pressure tests, waterproofing test records, equipment commissioning reports and other inspections required by the project.
These reports document what was checked, when it was checked and whether any issue remained open at handover.
4. Equipment manuals and operating instructions
Pumps, air-conditioning units, lifts, generators, solar systems, fire safety equipment and other installed products may each have operating instructions. These should be collected in one accessible place.
The handover should also identify the locations of main electrical switches, water shut-off valves and other essential controls. The person managing the building should be shown how to use them.
5. Warranties and supplier details
The handover file should include available warranties for equipment, fixtures, waterproofing systems and other supplied products, together with the details needed to make a claim. It should state when each warranty begins, what it covers and whom to contact.
Clear records make after-sales support more effective than a general assurance that “everything is under warranty.”
6. Materials, finishes and maintenance information
Paint shades, tile references, sanitaryware models, hardware specifications and similar details help the owner source matching materials for future repairs.
Maintenance guidance should explain which equipment needs regular servicing and which finishes or sealed areas need particular care.
7. A contact record of the people involved
One of the most useful handover documents can be a project contact sheet. It should identify the architect, structural engineer, project engineer, site supervisor, specialist contractors and key suppliers. Where appropriate, it should also include the main workers or technicians who carried out plumbing and electrical installations.
The person who installed a concealed pipe or wired a distribution board may remember practical details that are difficult to find later. Their knowledge can help locate a fault quickly and avoid unnecessary damage during repairs. This is particularly helpful when the same person can return to carry out maintenance.
The contact sheet should state each person’s name, role, area of work and contact number. Personal numbers should be shared with the individual’s agreement, and the owner should also have a company or contractor contact if that person is unavailable. The contact sheet supports the drawings and service records; it does not replace them.
8. Snag list and closure record
A handover inspection may identify small items that still need attention. These should be recorded with the person responsible and an agreed completion date. Their closure should then be documented.
This gives the client and project team a shared understanding of what is complete and what remains to be done.
9. Final account and handover note
The final account should record the agreed contract value, approved variations, payments and any balance due. A signed handover note can list the drawings, certificates, manuals, warranties, contact sheet, keys and access items delivered to the owner, along with the handover date and any outstanding work.
Why handover documentation matters
A complete handover file helps owners operate systems correctly, plan maintenance and respond faster to faults. It gives future architects, engineers and contractors a reliable starting point for repairs or alterations. It also preserves the knowledge of the people who designed and built the project, while they are still available to explain their work.
For the project team, documentation connects design decisions, construction, testing and final delivery. Preparing it should begin during the project, rather than after everyone has left the site.
At DH Infra Projects LLP, we believe project completion should give the client more than a finished building. A thoughtful handover gives them the records, contacts and knowledge to use it with confidence. The keys open the building; the handover information helps the owner take care of it.
