What are O&M manuals?
An operation and maintenance (O&M) manual is the reference the building or system owner relies on after handover. It brings together how the system works, how to operate it, how and when to maintain it, and the design, test and commissioning records behind it. A good O&M manual is complete, current and easy to navigate, and it is often a condition of practical completion.
What's included
- System descriptions and operating information
- Maintenance requirements and schedules
- The latest approved drawings, design details and RAMS
- Test, commissioning and handover records
- A clear index showing what is included, and anything still outstanding
How EJH produces O&M manuals
We compile the O&M manual from the latest approved revision of every document, never an out-of-date draft. Because we track approval for every document, any gap is visible well before handover rather than discovered afterwards. Paired with the project journey pack, it gives your team both the how and the why.
What it means for your project
- A complete, current manual at handover
- Only approved revisions, so your team works from the right information
- Gaps identified early, protecting practical completion
- Easier maintenance and lower lifetime cost
Frequently asked questions
What is an O&M manual?
An operation and maintenance manual is the document set that tells the owner how a system works and how to operate and maintain it, together with the design, test and commissioning records behind it.
How do you make sure it's up to date?
We only include the latest approved revision of each document, and the manual's index shows anything that is not yet approved, so gaps are closed before handover.
Can you produce O&M manuals for work you didn't deliver?
Yes. We can compile and review O&M documentation for systems delivered by others, identifying anything missing.
