Fire Compartmentation Surveys

Unknown compartment lines, alterations above ceilings and gaps around new services can justify a survey. Describe when the issue started and any change in use, operation or layout. A clear history helps distinguish a new fault from an existing limitation or a planned improvement.

Tell us what needs doing

If tenants or other occupiers are affected, record which areas they use and who controls them. This helps prevent an instruction for one property area overlooking a shared system.

What the work can include

Review available plans; inspect accessible boundaries, voids and penetrations; locate defects; distinguish observations from areas needing further opening-up. The agreed scope should state which areas or equipment are included, what is excluded and the form of the completion record.

Ask for findings that identify the affected item or location clearly. A useful record allows you to understand what was done and arrange any follow-on work without starting again.

Important decisions

A non-intrusive survey cannot confirm hidden construction. Agree which openings are permitted and how disturbed finishes will be reinstated.

Assessment and preparation

Supply fire strategy drawings, asbestos information, previous surveys and access arrangements for ceilings and risers.

Confirm keys, occupant notices, parking or unloading access and the person able to authorise additional work. Photographs can help explain the enquiry where they can be taken safely.

How the work proceeds

Establish the intended boundaries, inspect agreed areas and issue location-linked findings that can support a remedial specification.

Agree any stages before work starts: investigation, a repair proposal and the authorised work may be separate instructions. At completion, establish what can be used, what remains restricted and what happens next.

Cost, timing and disruption

Survey extent, concealed spaces, high-level access, opening-up and reinstatement determine effort. The enquiry and available records establish what can be priced directly and what needs a site assessment first.

Where work affects an entrance, occupied room or shared service, arrange the access window with the people using it. Include any temporary arrangements and reinstatement in the scope so the quotation addresses the whole job.

Applications across sectors

Sleeping accommodation raises different evacuation and access considerations from daytime offices. Education premises need work arranged around children and staff; warehouses need attention to storage and changes in layout. The actual use and fire arrangements govern the scope. Browse the full sector range and describe the actual building use when enquiring.

Locations covered

We cover Northumberland, Tyne and Wear, County Durham and Tees Valley, including Newcastle upon Tyne, Gateshead, Sunderland, Durham, Darlington, Middlesbrough and the wider towns and communities in our location directory. Send the property address and the area of the building needing attention so access and the work requirement can be considered together.

Frequently asked questions

Can photographs alone establish fire resistance?

Photographs can record visible condition, but the construction, tested system details and concealed elements may need further evidence.

What information should I send about fire compartmentation surveys?

Supply fire strategy drawings, asbestos information, previous surveys and access arrangements for ceilings and risers. Include the location and the decision you need to make, such as investigating a fault, planning a repair or setting up a programme.

What affects the price and programme?

Survey extent, concealed spaces, high-level access, opening-up and reinstatement determine effort. Any further investigation or additional work should have a clear scope before it is authorised.

What should the completion information explain?

It should identify the equipment or areas covered, the work and checks performed, limitations and unresolved actions. Keep the record with the property information and share relevant operating instructions with the people who use the equipment or space.

Useful guidance and records

Read what should a fire logbook contain for the supporting decisions and records. Remedial-action tracking explains how to carry an identified defect through to evidenced closure. The relevant official guidance provides the wider technical or management context.
