Of all the deliverables at the end of a construction project, the handover information is the one most likely to be thrown together at the last minute — a rushed box of manuals and a file assembled to tick a regulatory box. That is a mistake on two fronts. The Health and Safety File is a legal requirement under the CDM Regulations, and the operation and maintenance information is what determines whether the client can actually run and look after the building. Treated properly, both are among the most valuable things you hand over.
The Health & Safety File
The Health and Safety File is required under CDM 2015 for projects involving more than one contractor. Its purpose is narrow and important: to provide the information anyone carrying out future construction, maintenance, cleaning, or demolition work will need to do that work safely. It is not a dumping ground for every document on the project. It should contain the residual risks and how they have been dealt with, key structural principles, information on hazardous materials, and the details of services and safety-critical equipment — the things a future worker genuinely needs to know to avoid harm. Assembling it is coordinated by the principal designer, drawing on information from the whole team, and it is handed to the client at the end. Our guide to appointing a principal designer under CDM 2015 explains who carries that duty.
O&M manuals and asset information
Where the H&S File is about safety, the operation and maintenance manuals are about running the building. Good O&M information tells the people who manage the building how everything works, how to operate it, how to maintain it, and who made and installed it. At its best it includes clear operating instructions, planned maintenance requirements, warranties and guarantees, test and commissioning records, and as-built information. The test is practical: could a facilities manager who never met the project team keep this building running properly using only this information?
Who is responsible — and why it goes wrong
Responsibility is shared, which is precisely why handover information is so often poor. The principal designer coordinates the H&S File; the contractor and specialist subcontractors provide much of the O&M content; and the client must actually receive, keep, and use it. The failure mode is predictable: nobody owns the overall deliverable, so information arrives late, incomplete, and in inconsistent formats. The fix is to treat handover information as a managed deliverable from the start — specified in the appointments, structured in the common data environment, and assembled progressively rather than in a panic at completion.
- Specify the requirements early. Say what you need, in what format, from whom, in the appointment documents — not at handover.
- Assemble it progressively. Collect information as the work is done, while it is fresh and the people responsible are still on the project.
- Give it one owner. Make someone responsible for the completeness and quality of the whole handover pack.
The bottom line
The Health and Safety File keeps future workers safe; the O&M information keeps the building running. Both are only as good as the planning behind them. Specify them early, assemble them as you go, give them a clear owner, and you hand over something genuinely useful — not a box that satisfies a regulation and helps no one.
