Compartmentation Surveys

Fire compartmentation surveys assess how effectively a building can contain the spread of fire and smoke. Senseco Systems’ experienced surveyors inspect fire-resisting walls, floors, doors, cavity barriers, and service penetrations within an agreed scope, identifying defects that could compromise compartmentation and documenting any remedial actions required.

As an independent fire safety specialist, Senseco provides impartial advice and clear reporting to help building owners, facilities managers, and responsible persons understand the condition of their passive fire protection and maintain compliance with fire safety requirements.

What a fire compartmentation survey involves

Fire compartmentation is the practice of dividing a building into fire-resisting compartments using walls, floors, doors, and other passive fire protection measures. These compartments are designed to slow the spread of fire and smoke to help protect occupants, escape routes, and critical areas of the building.

During fire compartmentation surveys, experienced surveyors will assess the integrity of these protective barriers and identify any defects that could compromise their performance. Depending on the agreed scope, this could include inspecting compartment lines, fire doors, fire stopping around service penetrations, and cavity barriers within concealed spaces. The survey establishes whether fire-resisting elements remain intact and highlights any breaches or shortcomings that would require remedial action.

The importance of building compartmentation for fire safety compliance

Effective compartmentation is a fundamental part of a building’s fire safety strategy. By containing fire and smoke within a defined area, compartmentation helps to protect escape routes, limits damage to the building, and provides occupants with more time to evacuate safely. It also supports the performance of other fire protection measures, including fire detection, fire suppression, and emergency evacuation procedures.

Effective compartmentation supports adherence with fire safety duties such as fire safety order compliance. In England and Wales, under the Regulatory Reform (Fire Safety) Order 2005, responsible persons have a duty to take appropriate measures to reduce the risk of fire and protect building occupants. Where compartmentation has been compromised by building alterations or poor maintenance, a survey can identify issues that could affect compliance and require remedial action.

Signs your building’s compartmentation may be compromised

Compartmentation can be compromised over time through building alterations, maintenance work, ageing materials, or poor-quality installations. In many cases, defects remain hidden until a detailed inspection is carried out, creating risks that may not be immediately obvious during day-to-day building management.

Common warning signs include unsealed service penetrations where cables, pipes, or ductwork pass through fire-resisting walls and floors, damaged or poorly fitting fire doors, and missing, damaged, or incorrectly installed cavity barriers. Evidence of unauthorised building works, changes to layouts, or legacy installations can also indicate that compartment lines have been breached.

Rather than waiting for an audit, fire risk assessment, or incident to uncover these issues, a compartmentation survey provides a proactive way to identify defects and address them before they affect fire safety performance or compliance.

Senseco’s compartmentation survey process

Our compartmentation surveys follow a structured process, from agreeing the scope of the survey, through to identifying defects on site, documenting findings and supporting any remedial works required.

Agreeing the survey scope and access

Before the survey takes place, we’ll agree the scope with you, including the areas of the building to be inspected and any access arrangements. Concealed areas such as ceiling voids, risers, and service cavities might require opening up or further investigation before they can be assessed, so these requirements will be discussed and planned in advance.

On-site inspection and defect identification

The on-site inspection will be carried out by one of Senseco’s experienced surveyors. During the survey, the agreed compartment lines are assessed to identify any breaches, damage, missing fire-stopping materials, or other defects that could allow fire and smoke to spread beyond their intended boundaries.

Surveyors examine the condition of fire-resisting walls, floors, service penetrations, cavity barriers, and other passive fire protection measures, building a clear picture of the effectiveness of the compartmentation strategy across the inspected areas.

Clear defect documentation and reporting

Following the inspection, Senseco provides a detailed report outlining the findings. Defects are clearly documented, with locations identified and supported by photographic evidence where appropriate, to make it easier to understand the extent and priority of any remedial work required.

The report also records any areas that could not be accessed and any other limitations of the survey, so you have a clear understanding of what has been inspected and where further investigation might be needed. This gives responsible persons a clear record of the condition of their compartmentation, helping to support maintenance planning, compliance activities, and future audits.

Remedial support

Where defects are identified, Senseco can provide remedial support to help restore the integrity of your building’s compartmentation. Remedial works are carried out in line with the relevant standards and fire safety requirements, focusing on the defects identified in the survey report. We aim to keep disruption to a minimum and keep you updated throughout.

Compartmentation surveys FAQs

What is a fire compartmentation survey?

A fire compartmentation survey is a detailed inspection of a building’s fire-resisting walls, floors, doors, cavity barriers, and fire stopping measures. Its purpose is to identify defects or breaches that could allow fire and smoke to spread beyond their intended compartments and to provide recommendations for any remedial action required.

What is the main objective of fire compartmentation?

The main objective of fire compartmentation is to slow the spread of fire and smoke throughout a building. By containing a fire within a defined area, compartmentation helps protect escape routes, supports safe evacuation, reduces property damage, and contributes to the overall fire safety strategy.

Is a compartmentation survey a legal requirement?

A compartmentation survey is not specifically mandated by legislation in every building. However, under the Regulatory Reform (Fire Safety) Order 2005, responsible persons have a duty to ensure appropriate fire safety measures are in place and maintained. A compartmentation survey can help demonstrate that passive fire protection systems remain effective and compliant.

How much does a fire compartmentation survey cost?

The cost of a fire compartmentation survey depends on factors such as the size and complexity of the building, the number of areas requiring inspection, and the level of reporting required. For an accurate quotation tailored to your premises, contact Senseco to discuss your requirements.
