Building owner's manual - O and M manual
The building owner's manual is prepared by the contractor or the sub-contractor with additional information from the designers (in particular, the services engineer) and suppliers. It is a requirement that is generally defined in the preliminaries section of the tender documentation where its contents will be described, although there may be additional requirements regarding mechanical and electrical services in the mechanical and electrical specification.
A draft version of the document should be provided for the client as part of the handover procedure prior to certifying practical completion. The final document is not usually available in full form until several months after practical completion, as commissioning information often needs to include summer and winter readings taken in the fully occupied building. The preliminaries may require several copies of the building owner's manual and might require an electronic version.
The building owner's manual might include:
- A description of the main design principles.
- Details of the building's construction (such as finishes, cladding, doors and windows, roof construction, and so on).
- As-built drawings and specifications.
- Instructions for its operation and maintenance (including health and safety information and manufacturers' instructions for efficient and proper operation).
- An asset register of plant and equipment.
- Commissioning and testing results.
- Guarantees, warranties and certificates.
- Particular requirements for demolition, decommissioning and disposal.
Over the life of the buildings, the building owner's manual may be developed to reflect changes that take place to the fabric of the building or its systems, along with details of maintenance that has taken place .
The building owner's manual is different from the health and safety file which only needs to include information important to health and safety and does not need to include information about the construction process, contractual information or information about the normal operation of the completed structure.
