Handover Documentation And As-Built Records
A handover pack is not a formality. It is the record of what was built, what it was certified against, and how it is maintained, and the parts that are missing are the parts that cost money later.
What should be in a handover pack for a modular building?
As-built drawings reflecting what was actually constructed, the certificates and compliance documentation for every element that required them, warranty documents with their start dates and conditions, operating and maintenance instructions for every system and appliance, the asset register with model and serial numbers, and the service and inspection schedule with the first due dates set.
The documentation handed over at completion is used for the next thirty years by people who were not involved in the project.
Which is why a thin handover pack is expensive. Every gap in it becomes an investigation later, usually at the worst moment, and usually paid for by whoever owns the building rather than whoever built it.
As-built, not for-construction
The distinction that matters most.
For-construction drawings show what was intended. As-built drawings show what exists, including every variation made during delivery.
A service run moved to clear a structural member. A penetration relocated. An outlet added at the resident's request. A fixture changed because of availability. Each one is reasonable at the time and each one makes the original drawing wrong.
Somebody will drill into a wall in five years. Whether they hit a cable depends entirely on whether the as-built record was kept.
In a factory build the record is easier to keep and more important to keep, because much of what matters is inside a wall or a floor cassette that was closed in the factory and will never be opened on site. Which means the record is captured during fabrication, with photographs before linings go on, not reconstructed at completion.
The compliance documentation
Everything that required a certificate, with the certificate attached.
Structural certification. Fire and acoustic test evidence for the systems used, not for similar systems. Waterproofing. Electrical and plumbing compliance certificates. Glazing. Energy performance. Termite protection. Any engineering sign-off for a specific element, including the structural provision for equipment such as a ceiling hoist.
The common failure is a pack with the certificates for the installed work and nothing covering the factory-built elements, because those were certified through a different pathway. Both halves are needed, and how they fit together is the subject of [who certifies a factory-built building](/blog/who-certifies-a-factory-built-building).
Warranties, with dates and conditions
A warranty document on its own is incomplete.
What is needed is the start date, the duration, what is covered, what voids it, and what maintenance is required to keep it valid. That last item is the one that catches people: a roof or membrane warranty conditional on an inspection regime is void if the inspections were never done, and nobody knew they were required because the condition sat in a document nobody read.
So the maintenance obligations attached to warranties are extracted into the maintenance schedule, not left buried in the warranty itself. The relationship between the two is covered in [defects and warranty in modular delivery](/blog/defects-and-warranty-in-modular-delivery).
The asset register
Every item that will ever need a part: make, model, serial number, location, supplier, installation date.
Appliances, hot water units, air conditioning, exhaust fans, the hoist, door hardware, locks and keying, light fittings, tapware.
Without it, replacing a failed component in year six starts with somebody identifying what it is from a photograph. With it, the part is ordered the same day.
The locking and keying record is its own item and it is frequently missing entirely, which matters from the moment of [security and lock-up after installation](/blog/security-and-lock-up-after-installation).
Operating and maintenance instructions
Written for the people who will use them, which in supported accommodation means support workers and a maintenance contractor rather than an engineer.
What each system does, how it is operated, what the normal settings are, what to do when it behaves abnormally, and what gets serviced when.
A folder of manufacturer manuals is raw material, not a document. The useful version is a short building-specific guide with the manuals attached behind it.
The maintenance schedule, with the clock started
A schedule with intervals and no dates is a schedule nobody follows.
The handover version has the first due date on every item, calculated from the actual completion date, so the first year of maintenance is already programmed. That is what makes the whole-of-life numbers in [maintenance and whole-of-life costs](/blog/maintenance-and-whole-of-life-costs) achievable rather than theoretical.
Hand it over digitally and physically
A digital set that can be searched, shared and backed up, and a physical set on site for whoever is standing in the building without a laptop.
And a walkthrough at handover with the people who will operate the building, because the pack explains what exists and a walkthrough explains where it is.
