New-building fire acceptance: FS172, testing and document preparation
New-building acceptance differs from annual inspection. Understand OFFA coordination, FS172 versus FS251, and how to prepare plans, tests and defect evidence for the project.
If there is fire or immediate danger
Leave the premises using a safe route and call Hong Kong emergency services on 999. Do not remain to investigate or use a lift.
Legal information
This guide helps with initial planning; it is not legal advice or an engineering assessment of your premises. Confirm the requirements against the use, approved plans, licence conditions, written directions and current official documents.
Quick answers
Can FS251 replace FS172 for a new building?
No. They are issued by different parties under different processes. Prepare the documents required for the particular work and acceptance procedure.
Assign responsibilities for joint tests
The main contractor, E&M and fire teams can list the equipment, power, attendance and prerequisite work for each test. Assign document versions and outstanding actions so completion by individual trades leads to readiness for the combined tests.
Have the relevant teams confirm changes to site conditions or scope before updating the record. A management checklist does not replace required drawings, tests or authority documents.
Distinguish acceptance from annual inspection
New-building FSI acceptance involves approved plans, site inspections and document checks. FSD's OFFA coordinates the process; it does not remove the required testing or supporting records.
FS172 is issued by FSD under the relevant new-building acceptance process and differs from a contractor's FS251. Receipt of an FS251 alone does not establish completion of the building's fire acceptance.
Reconcile drawings, installations and test evidence
Have the project team consolidate current drawings, equipment lists, test reports and open items, then reconcile them against the installation. Clear version control helps avoid the same discrepancy recurring across inspections.
Before inspection, confirm water, power, access, interfaces and operating personnel with each trade. Identify items that are not ready for testing accurately in the application coordination and programme.
Update evidence after rectification
Link each finding to the repair, repeat test and drawing revision that address it. A completion statement without corresponding evidence makes inspection and document follow-up harder for the project team.
Set handover dates from actual site and document readiness rather than treating official service targets as a guarantee for the project. Give the operating team equipment, maintenance and outstanding-action records at handover.
Practical checklist
- Current approved plans and equipment lists
- Tests, interfaces and water/power readiness
- Trade access and operating personnel
- Findings, repairs and repeat-test evidence
- Document versions and management handover
Discuss fire installation and acceptance coordination
Share the plans, equipment scope and intended inspection period so we can review installation, testing and documentation support.
- Fire-installation and alteration works
- Coordinate tests and rectification with the project team
- As-built drawings, reports and handover records
