    Fire Compartmentation Surveys

    Inspect the accessible barriers intended to limit fire and smoke spread.

    Scoped

    the instruction and exclusions are agreed in writing

    Evidence-led

    unknowns and access limits stay visible

    Actionable

    the output supports a defined project decision

    When this service is useful

    Concealed defects and unrecorded service penetrations can undermine the compartmentation assumed by a strategy or risk assessment.

    A defined visible or intrusive survey of agreed compartment lines, areas or samples, recording observations, evidence and access limitations.

    Primary outcome

    A location-referenced survey report with observations, limitations and prioritised actions for the agreed scope.

    A fire risk assessment identifies compartmentation concerns

    No reliable passive-fire records exist

    Refurbishment has introduced service penetrations

    Sample opening-up is required

    Remediation planning needs a baseline

    What your report includes

    Written outputs depend on the agreed scope.

    The report records the information supplied, the assumptions used, the limitations that apply and the actions or technical position within the agreed service scope.

    Survey scope and access plan

    Location-referenced observations and photographs where agreed

    Fire-stopping, cavity barrier and compartment-line findings where visible

    Evidence and access limitation schedule

    Prioritised recommendations for investigation or remediation

    How we scope and coordinate the work

    The service is defined before the fee is quoted.

    The scope is set from the building facts, drawings, jurisdiction, project stage and the question the written output needs to answer.

    Scope point 01

    Survey population stated

    Full, sampled and excluded areas are distinguished.

    Scope point 02

    Access limits mapped

    Inaccessible or concealed locations remain visible in the report.

    Scope point 03

    Action-ready record

    Findings are location-referenced for further investigation or remediation planning.

    From enquiry to written report

    A clear sequence from information request to issued output.

    Every stage records what has been supplied, what remains open and what the report can and cannot conclude.

    01

    Define lines

    Agree compartment lines, areas, sample and access.

    02

    Review evidence

    Check strategy, plans and historic records.

    03

    Inspect

    Carry out visible or agreed intrusive inspection.

    04

    Record

    Map observations, photographs and limitations.

    05

    Prioritise

    Issue actions and further-investigation needs.

    Recorded basis

    A scoped, documented technical process

    The question, available evidence, access and required output are agreed before a quotation is issued.

    Scope and exclusions agreed
    Evidence and limitations recorded
    Written output issued

    Result

    The report covers only agreed accessible areas or samples and makes no blanket certification claim.

    Information needed for a quotation

    What we need from you to scope the work.

    • Building plans and intended compartment lines
    • Fire strategy and previous surveys
    • Areas, samples or interfaces to inspect
    • Access and opening-up permissions
    • Occupied-building constraints and reinstatement arrangements
    Scope boundaries

    What this service does not include.

    • The report covers only the agreed areas or sample.
    • Visible surveys cannot verify concealed construction.
    • Intrusive opening-up and reinstatement require explicit agreement and coordination.
    • The survey is not blanket certification of the building or installation.
    Suitable scope examples

    Buildings and uses this service scope suits.

    These are examples of building types, uses and project contexts for which this service scope is suitable. They are scope examples, not a client list or a record of completed instructions.

    • Housing associations and property managers
    • Building engineers and surveyors
    • Developers and architects planning refurbishment
    • Insurers reviewing passive-fire evidence

    Questions about this service

    Is the survey intrusive?

    It can be visible or intrusive. The extent of opening-up and responsibility for reinstatement are agreed before work starts.

    Does a sample cover the whole building?

    No. A sample supports conclusions only for the inspected population and limitations stated.

    Will the report certify compartmentation?

    No. It records observations and limitations for the agreed scope; it is not blanket certification.
