Compartmentation Surveys

What is a Compartmentation Survey?
Detailed compartmentation surveys are assessments of how well a dwelling can protect important escape routes and high-value areas. This includes roof spaces, service risers and floor voids. Also, to maintain the integrity of a compartment to stop the vertical or horizontal spread of fire, heat smoke and fumes. We offer five different types of surveys, depending on the needs/requirements of the client or building.
Compartmentation Surveys
OBSERVATIONAL
Non-intrusive visual inspection of compartment walls, soffits, voids, cavities on the means of escape, protected stair cores and high-risk areas. We will identify all life cycle, maintenance, and latent defects with a technical written and photographed report.
SECTIONAL – VISUAL
Access is typically required to 3 floors. Inspection of sections of the floor template (not the whole floor), across several levels (not all levels). This will allow us to make an informed decision on the condition of the compartmentation, using the balance of probability. It will identify breaches in compartmentation walls/soffits, voids, cavities within the means of escape, protected stair cores and high-risk areas. Information is captured in specialist software for reporting. Floor layout drawings will be required free of charge.
SECTIONAL – INTRUSIVE
As per Sectional – Visual but previously inaccessible areas will be inspected by drilling a small hole through the substrate to enable an inspection by use of a borescope. A larger core drill may then be employed for opening up soffits, voids and cavities as required. Holes will be temporarily filled/covered on completion.
FULL – VISUAL
Access is required to all parts of the building where all breaches in compartmentation walls, voids, cavities in the means of escape, protected stair cores, high-risk and sleeping areas are identified. Information is captured in specialist software for reporting. Floor layout drawings will be required.
FULL – INTRUSIVE
As per Full – Visual previously inaccessible areas will be inspected by use of a borescope and/or opening up soffits, voids and cavities as required.
Once the survey is completed, we’ll provide you with a written report including a plan of the area and an action plan detailing the required improvements and the fire stopping that may need to take place.


Cavity Barriers
When constructing a building with voids and cavities, it’s crucial to incorporate cavity barriers to effectively halt the unseen fire spread within concealed cavities.
Fire Compartmentation
Compartmentation plays a vital role in building fire safety by dividing structures into distinct sections that can contain and control the spread of fire.
Fire Dampers
Fire dampers are crucial for creating barriers that resist the spread of fire and smoke through ductwork systems.
FAQs
A fire compartmentation survey is typically conducted on buildings to assess and ensure that adequate fire compartmentation measures are in place. Fire compartmentation is a crucial aspect of fire safety design and involves dividing a building into separate compartments or zones to prevent the spread of fire and smoke. The specific buildings that may require a fire compartmentation survey include:
• Commercial buildings
• Residential buildings with communal corridors and lobbies
• Industrial buildings
• Education institutions
• Healthcare facilities
• Public/Government buildings
• Transportation hubs
• Entertainment venues
Regular surveys and inspections help ensure that fire compartmentation measures are maintained and that any issues are identified and addressed promptly to enhance overall fire safety within a building.
There is no definitive answer to this question. The duration will vary depending on the size/type of building and the quantity of compartmentation.

Yes, fire compartmentation surveys are typically a component of a comprehensive fire risk assessment. A fire risk assessment is a systematic evaluation of a building or premises to identify potential fire hazards, assess the risk of fire, and determine the effectiveness of existing fire safety measures. Fire compartmentation surveys specifically focus on evaluating the effectiveness of compartmentalisation measures within a building.
