How to Build Your Contractor Handover Pack

What is a contractor handover pack and why does it matter?

A handover pack is the bundle of documents and records you give the owner at the moment of formal building handover. It closes the construction phase on paper the same way the physical work closes on site. For most Thai SME contractors, handover is a key handover and a phone call — no documents, no formal record, no signed acceptance. That gap is where payment disputes and warranty arguments are born. A handover pack does three things at once: it proves the work is complete, it establishes the formal start of the defects liability period, and it gives the owner everything they need to operate and maintain the building without calling you for every small question after they move in.

What should go into every contractor handover pack?

The core of the pack has six items. First, the final Gantt schedule exported or printed from the project plan, showing all tasks at one hundred percent — this is your record of what was built and when. Second, the signed punch list with every item resolved and the owner's initials against each one. Third, photographs of completed work at every major stage — structure, MEP rough-in, and finishes — ideally exported from the on-site progress updates log. Fourth, warranty certificates from suppliers and subcontractors, particularly for MEP systems, waterproofing, and specialist finishes. Fifth, a one-page material specification: tile brand and colour code, paint shade, fixture model numbers. Sixth, the signed formal acceptance letter with the handover date, which starts the DLP clock.

Why the completed Gantt is your most powerful handover document

An owner who sees a completed Gantt chart at handover — every task bar at one hundred percent, every milestone marked done — understands the project history in a way no verbal summary conveys. The plan shows what was built, what order it happened in, and when each phase closed. In the Gantt planning view, SiteBoard updates in real time as the foreman logs progress, so by handover day the chart already reflects the true history of the build. You do not need to produce a separate completion certificate — the plan is the record. Share the owner-sharing link at the meeting and the owner has an interactive version they can return to long after the handover documents are filed away.

How to photograph the completed building for the handover record

The handover photo record should cover three layers: completion photos of each major system or phase taken by the foreman as each task reached one hundred percent in SiteBoard, a final walkthrough set taken the day of the punch list sign-off, and any specialist test photos — the water pressure test on plumbing, the load test on the electrical panel. These do not need to be professional photographs. Clear, well-lit phone photos with a timestamp visible in the on-site progress updates log are sufficient evidence. The critical point is that they live inside the project record alongside the task they document, so every image comes with a date and context that cannot be separated from it later.

A worked example: handover pack for a 2.4 million baht home renovation in Pathum Thani

Khun Somboon completes a 2.4 million baht whole-house renovation in Pathum Thani: new structure, full MEP, and complete finishes. His handover meeting runs forty minutes. He opens the owner-sharing link on his tablet and walks the owner through the completed Gantt: structure closed in week three, electrical and plumbing rough-in by week seven, finishes complete by week twelve. He passes a printed punch list with all eleven items resolved and the owner's initials on each. He adds an envelope with warranty cards for the water heater, air conditioning units, and waterproofing membrane, plus a single-page spec sheet listing paint brands, tile codes, and switch model numbers. The owner signs the acceptance letter. The handover is documented, the DLP starts that day, and the final payment of 240,000 baht — ten percent retainage — is released by transfer before the meeting ends.

How does the owner sharing link help during the handover meeting?

Showing the owner the live project through the owner sharing link turns the handover from a presentation into a joint review. The owner sees the same progress timeline they watched throughout the build, now with every bar at one hundred percent. They can scroll through photo updates logged at each phase. If they ask when the waterproofing was done, the answer is in the timestamped record — not in memory. The shared link also becomes a reference the owner keeps after the meeting: the next time they need to know when the DLP ends or which subcontractor ran the MEP, the project record is one tap away. No separate binder to lose, no calls to you for information that is already documented.

What if the owner will not sign the formal acceptance?

An owner who refuses to sign the acceptance letter is usually doing one of two things: raising a legitimate outstanding item the punch list missed, or stalling to delay the DLP start. For the first case, add the item to the punch list, fix it within a specific agreed timeframe, and return for a second sign-off meeting. Do not let a minor item sit open indefinitely — set a return date and document it in writing. For the second case, the completed Gantt, the signed punch list, and the photo record from on-site progress updates are your evidence that work is genuinely complete. A builder who has documented every step of the project is in a strong position if sign-off is unreasonably withheld.

FAQ: How long should you keep handover pack documents?

Keep everything for at least the length of the defects liability period plus two years. For a one-year DLP, that means three years minimum. For government contracts with a two-year DLP, keep records for four years. The biggest risk of discarding records early is a post-DLP claim that argues the defect predates the warranty expiry. A dated, signed acceptance letter with the resolved punch list attached is the simplest defence against that argument. In practice, digital records in SiteBoard persist automatically as long as you maintain the account. Printed copies should go in a physical file per project, labelled with the project name and formal acceptance date, stored somewhere you can retrieve them without searching for half an hour.

FAQ: Do subcontractors need to provide their own handover documents?

Yes — and collecting them before the final handover meeting saves considerable stress. Each major subcontractor should provide a warranty certificate or letter covering their scope, signed and dated on the day their work passes inspection. For MEP subcontractors, that typically includes test certificates for the electrical installation and plumbing pressure tests. For waterproofing specialists, it is a signed warranty stating the product applied and the date of application. If a waterproofing failure appears in month eight of the DLP and the subcontractor cannot produce a warranty document, you absorb the repair cost yourself. Collecting these certificates as each sub closes out — not at the final handover when teams have already moved on — is the discipline that protects your costs through the defects period.

FAQ: What is the difference between practical completion and final completion?

Practical completion is the point at which the works are sufficiently complete for the owner to take possession and use the building, even if minor punch list items remain. It is the trigger for the defects liability period and usually for the release of most retainage. Final completion comes at the end of the DLP, when all defects have been addressed and the contractor's obligations are fully discharged — triggering any remaining retainage release. In Thai private construction contracts, the distinction is not always formally named, but it operates in practice: the owner moves in before every snagging item is closed. Documenting the acceptance date clearly at handover and separating it from the eventual DLP-end sign-off prevents the two events from being conflated months later when it matters most.
