Two weeks to practical completion, and a box file
The building looks finished. The client's facilities manager asks for the O&M manual, the as-built drawings, the product data sheets, the commissioning records and the warranties. Your site manager opens a box file and a shared folder. The roofer's guarantee has not arrived. The M&E firm's commissioning records are waiting on a sub-subcontractor. The window supplier's installation certificate was emailed to someone who has since left. The flooring contractor finished three months ago and is now hard to reach.
Most of the last fortnight goes on chasing paperwork rather than finishing the building.
Why the handover file is always last
The O&M file is treated as an end-of-job task, but it is made of documents that each belong to a moment in the job. A trade's product data exists when it orders; its installation records exist when it finishes. Asking for everything at the end means asking firms that have gone, about work they have forgotten.
- Nobody lists the required documents per package at the start.
- Subcontract orders mention O&M information in general terms only.
- Documents arrive by email to different people in different formats.
- Red-line mark-ups for as-builts sit in site offices, not with the designer.
- Final payments are released before the documents are complete.
What a late handover file costs
Handover drags or happens with an incomplete file and a list of outstanding items that follows you for months. Your client's facilities team starts running a building without the information it needs, and comes back to you for it. Site managers stay on a finished job to chase paper instead of starting the next one. Whatever your contract says about handover information, and your advisers are the people to ask about that, a late file damages how the client remembers the job.
The handover tracker we build
- At the start of the job, the client's handover and O&M requirements are turned into a checklist per trade package: product data, installation records, test and commissioning records, warranties, as-built information.
- Each subcontractor gets its own list and a secure upload link when its order is placed, so it knows from day one what it will need to provide.
- Items are requested at the right point: product data when materials are ordered, installation records when an area is signed off, warranties on completion of the package.
- Uploads are checked against the list. File type, project name and the product or area are read, and anything unclear goes to your document controller.
- Red-line mark-ups from site are photographed and logged against the drawing, then sent to the designer for as-built updates.
- Outstanding items per package are shown to the QS before final payment is approved.
- The O&M file is assembled in the structure the client asked for, with an index, and can be issued in the format they need.
| Document type | Requested when | Held against |
|---|---|---|
| Product data sheets | Materials ordered | Package and product |
| Installation records | Area signed off | Package and area |
| Test and commissioning records | Commissioning complete | System |
| Warranties and guarantees | Package complete | Package |
| As-built mark-ups | As changes happen on site | Drawing |
Handover without the box file
By the time the building is finished, most of the file already exists, because each item was collected while the trade was on site. The last weeks are spent on the few items that are genuinely late, and you know which ones. The client gets an indexed O&M file on the day. And the QS has a clear view of which subcontractors have not provided what they owe before releasing money.
Does your handover look like this?
- Handover documents are chased in the last weeks of the job.
- Subcontractors who finished months ago still owe information.
- As-built mark-ups never reach the designer.
- O&M files are assembled by hand from email attachments.
- Final payments go out before documents are received.
