Fire installation alterations: drawings, FS251 and FSI/314 documents
Moving sprinklers, hose reels or other fixed equipment during a fit-out calls for a review of drawings and scope. Understand what the documents do before coordinating the work.
Quick answers
Should documents be checked for moving only a few sprinkler heads?
Yes. Moving heads changes their layout. Share the proposed positions with the contractor so they can confirm the drawings, tests and documents needed before work starts.
Legal information
Requirements vary by premises. Confirm the work with the responsible professional using the premises use, approved plans, licence conditions and any written directions.
Identify what is changing
Replacing a faulty part and changing an installation layout may require different work and documentation. Mark proposed changes on the existing plan and identify changes to partitions, ceilings, use or fixed equipment positions.
Involve the fire contractor while the fit-out is being designed. Check sprinkler coverage, hose-reel positions and connections to other equipment before work starts, as these can affect ceilings, partitions and the construction schedule.
Confirm the certificates, drawings and forms needed
FSD's FAQs explain that layout or fixed-equipment changes may require drawings and FSI/314 documents alongside FS251. Ask the contractor to list the documents needed for your work and when each will be submitted.
The form depends on the work and premises. FSD lists FSI/314 and 314A alongside forms for commercial, composite or domestic, and industrial buildings. Have the responsible contractor confirm the current documents and submission sequence.
Keep drawings up to date through to handover
Share existing and proposed drawings, management requirements and relevant notices. The quote should identify responsibility for drawings, site work, testing and document follow-up.
If positions change during construction, ask the relevant teams to review the change. At handover, collect drawings reflecting the installation, test records and applicable certificates, with a list of outstanding documents.
