The O&M close-out timeline, from order to handover
Handover doesn't start at practical completion. It starts at the order.
Most late O&M manuals aren't late because someone was lazy. They're late because every document was asked for in the same fortnight, from people who'd moved on to the next job. This timeline spreads the work across the job, so by handover week there's nothing left to chase.
Counted back from handover. Move the weeks to suit your programme.
At contract award
Do: Find the O&M requirements in the spec. Agree the format, the structure and the sign-off date with the main contractor. Name one person on your side who owns the manual.
Who chases whom: You ask the main contractor for the client's requirements. They confirm them in writing.
When you place orders (from the start of the job)
Do: Put a document request on every order. Ask for the datasheet for the exact model, installation and maintenance instructions, warranty terms, and the spares list.
Who chases whom: Your buyer chases suppliers, with each order. Suppliers are quickest while the order is fresh.
During install
Do: Log serial numbers and locations as kit goes in. Save each document in one shared place as it arrives, named by system and product.
Who chases whom: Your supervisor chases the fitters for missing serial numbers at the end of each week. It takes minutes now and hours later.
About 8 weeks out
Do: First gap check. Run down the equipment list and mark what's in and what's missing.
Who chases whom: Your manual owner chases suppliers for the gaps. Commissioning dates go to the main contractor.
At commissioning
Do: File each certificate the day it's signed. Electrical certificates, fire alarm commissioning, flow readings, BMS points lists: in the folder the same day.
Who chases whom: You chase your commissioning engineers. A certificate that sits in a van for a month tends to stay there.
About 4 weeks out
Do: Send a draft manual to the main contractor for comments. Early, not on the last day. Book the FM team's training with the main contractor.
Who chases whom: The main contractor chases you for the draft. You chase the last certificates.
Two weeks before completion
Do: Check the manual for gaps. Close out the comments. Make the as-built drawings final. Chase the last few by phone.
Who chases whom: The main contractor chases you for the final version. You chase the stragglers.
At completion
Do: Hand over a manual that's already done. Record who received it and when. Run the FM team's training if it hasn't happened yet.
Who chases whom: The client's FM team checks with the main contractor. The main contractor checks your pack is complete.
After handover
Do: Keep it up to date when kit is swapped. At the end of the defects period, check the manual still matches the building.
Who chases whom: The FM team comes to you for changes. You update the manual once, in one place.
Three habits that make the timeline work
- Ask at order, not at handover. One line on the purchase order does most of the chasing for you. Free wording: supplier request wording
- File on arrival. A document saved the day it lands never needs finding later.
- One owner. If everyone owns the manual, nobody does.
Late paperwork can delay sign-off, final payment or retention release. Spreading it across the job is the cheapest way to keep it off the critical path.
