For architects and engineers, passive fire protection is rarely difficult in principle. The challenge is translating the fire strategy into details that can actually be constructed, inspected, maintained and documented once several trades begin occupying the same walls, floors, shafts and service zones.
A compartment wall on a drawing is straightforward. On site, that same wall may eventually accommodate cable trays, drainage, plastic and metallic pipework, ventilation systems, electrical containment and specialist services. Each penetration has to work with the fire-resisting construction rather than simply being treated as another M&E coordination item.
On apartment schemes, housing developments, healthcare facilities and larger commercial projects, specialist fire stopping input during design can resolve many of these interfaces while layouts and service routes can still be adjusted.
Why Should Passive Fire Protection Be Considered Earlier in the Design Process?
Early passive fire protection input allows architects and engineers to examine how proposed compartmentation will interact with the services that eventually have to pass through it.
The Building Regulations apply to the design and construction of new buildings in Ireland, and Technical Guidance Document B provides guidance on meeting the fire safety requirements of Part B. Primary responsibility for Building Regulations compliance rests with designers, builders and building owners.
For buildings other than dwelling houses, the current government publication is Technical Guidance Document B 2024 – Fire Safety, Volume 1, Buildings Other than Dwelling Houses (2026 Edition).
Those requirements establish the regulatory framework. Specialist input is concerned with translating the fire strategy into workable construction details.
Apparently minor decisions can have significant consequences later. Riser dimensions, the position and size of service openings, spacing between penetrations and the selected wall or floor construction can all influence which tested fire stopping solutions are suitable.
When services have already been installed, the available options are naturally more restricted. The design team may then be trying to accommodate an arrangement that was never considered from a fire stopping perspective.
What Do Fire Stopping Specialists See That May Not Be Obvious on a Drawing?
A specialist looks at the complete penetration rather than an individual service.
The wall may have the required fire resistance and the services may be properly coordinated from an M&E perspective, but the eventual penetration also involves the substrate, opening size, service type and dimensions, insulation, spacing, support arrangements and the tested fire stopping system intended to protect it.
Practical installation experience becomes particularly useful in congested areas.
It is not unusual to review a detail that appears reasonable on a coordinated drawing but becomes difficult once several services converge within a confined riser. Containment, brackets or pipework may be positioned immediately against the compartment line, leaving inadequate access to prepare the opening or achieve the required seal depth.
A relatively small adjustment to the service arrangement at design stage may resolve the detail. Once containment and services have been fixed, the same adjustment can involve considerably more work.
Why Are Service Risers Worth Reviewing Before Construction?
Service risers bring several disciplines together within a limited area and are particularly sensitive to changes between design and installation.
A typical apartment riser can contain electrical containment, telecommunications infrastructure, soil and waste pipework, water and heating services, together with other building systems. These services have to cross relevant compartment lines without undermining the intended fire separation.
On completed buildings, risers are also one of the areas where differences between drawings and installed conditions are frequently encountered. There may be more services than anticipated, openings can become larger and routes can move as installation progresses. Services shown with adequate separation during coordination may arrive at the floor slab much closer together.
Before construction, it is worth establishing whether there is sufficient space to install the proposed fire stopping system and whether the penetration arrangement can be supported by an appropriate tested detail. Access for installation and subsequent inspection also needs to be considered.
Those points are considerably easier to resolve while the riser layout is still being coordinated than once services are in place.
How Can Fire Stopping Design Affect Tendering and Cost Control?
Fire stopping is sometimes left as a specialist package to be resolved after the main construction details and service routes have already been developed. That can introduce uncertainty into the tender.
Where the compartmentation strategy, penetration types and likely service arrangements are understood, the fire stopping scope can be defined more accurately. Suitable systems can be considered against the proposed construction, quantities assessed with greater confidence and unusual interfaces raised before work starts.
This gives quantity surveyors and design teams clearer information when assessing tenders and reduces the amount of uncertainty that a specialist contractor has to allow for in pricing.
Flame Stop’s tender preparation process includes identifying fire stopping elements and developing cost-effective solutions appropriate to the relevant construction and project requirements.
What Happens When Fire Stopping Is Left Until Too Late?
Some of the more difficult fire stopping problems encountered during construction are coordination issues rather than failures in the underlying fire strategy.
A heavily congested opening through a compartment wall or floor is a typical example. Several services may have been installed independently, leaving limited clearances and insufficient space to install the intended fire stopping system in accordance with its tested configuration.
Containment fixed too close to a wall presents another familiar problem. The visible face may be accessible, while the area behind the tray or basket cannot be properly reached for preparation and sealing.
At that stage, the available remedies can include repositioning services, altering openings or introducing additional construction. These are avoidable complications on a project where programmes and follow-on finishes are already progressing.
How Can Architects and Engineers Improve the Design-to-Installation Handover?
Good passive fire protection relies on continuity of information between the fire strategy, detailed design and what is eventually constructed.
Changes during construction need to be captured. Revised service routes may require different penetration solutions, while product substitutions and altered site conditions need appropriate consideration. The installation ultimately inspected should correspond with the project information being handed over.
Irish building control procedures reinforce the importance of that record. In most relevant projects, completion documentation includes the Certificate of Compliance on Completion together with supporting compliance documentation and the Inspection Plan as implemented.
Guidance for the certification process also recognises that Assigned Certifiers may rely on specialist works contractors for ancillary completion certificates and should satisfy themselves regarding the certification provided by those specialists.
Clear records throughout the works make it easier for the project team to establish what was actually installed rather than relying solely on design-stage information.
Why Does Quality Assurance Matter During Fire Stopping Installation?
Much of a fire stopping installation eventually becomes concealed. Once ceilings are closed, risers completed and finishes installed, meaningful inspection becomes considerably more difficult.
Recording the work while access remains available is therefore important.
Photographs, locations, installation details and records of remedial actions allow individual installations to be reviewed before they disappear behind later construction. They also provide a more useful project record than attempting to reconstruct the installation history at completion.
Flame Stop operates an ISO 9001:2015 Quality Management System and uses industry-specific Boris software to monitor works in real time. This provides traceability during installation and supports the documentation required at project handover.
What Should Design Teams Look for in a Passive Fire Contractor?
Technical competence is only part of the assessment. On larger projects, the specialist needs to understand drawings and fire strategy information, recognise difficult interfaces and provide useful technical input where site conditions differ from the original assumptions.
The ability to engage before installation is also relevant. Identifying a problematic penetration while reviewing the proposed arrangement is preferable to discovering it once several trades have completed their work around it.
Flame Stop’s service provision includes:
- Passive Fire Stopping
- Fire Dampers
- Emergency Fire Alarm & Lighting Systems
- Intumescent Painting
- Fire Door Remedial Works
- Fire Door Installation Works
For architects, engineers and main contractors assessing fire stopping contractors Ireland, the ability to deal with related fire protection works while maintaining clear project records can simplify coordination on more complex schemes.
How Does Flame Stop Support Architects and Engineers in Practice?
Flame Stop can become involved while the project is still being developed rather than only when fire stopping installation begins.
Certified staff can undertake building analysis, surveys and reporting for consideration by the client or fire consultant. On refurbishment projects, this can help establish the condition of existing compartmentation and identify previous alterations before new works are designed around them.
Tender preparation allows relevant fire stopping elements to be identified before pricing is finalised. During construction, trained operatives undertake the specified works, supported by the company’s quality management and digital recording systems.
On completion, Flame Stop provides a suite of documentation for inclusion in the client’s O&M information.
The process gives architects and engineers a clearer link between the fire stopping requirements identified for the project and the work subsequently installed on site.
Can Fire Stopping Design Make Buildings Easier to Maintain?
Good fire stopping design Ireland should take account of the building after practical completion, particularly in service-heavy environments.
Apartment blocks, healthcare facilities and commercial buildings rarely remain unchanged. Fibre networks are added, security systems upgraded, tenants alter spaces and mechanical services are replaced. Risers and service zones that are already congested at handover can become particularly difficult to manage after several years of modifications.
Sensible service separation, accessible compartment lines and clearly recorded fire stopping systems make future maintenance easier to control. Maintenance teams are better able to identify where compartment lines occur and understand what may be affected before new penetrations are introduced.
A detail still needs to satisfy the project requirements at completion, but accessibility and future service intervention are worth considering while there is still flexibility in the design.
Why Is Specialist Passive Fire Input Valuable to Irish Design Teams?
Irish construction projects are increasingly service-intensive, while the responsibilities for demonstrating compliance extend across the design and construction process.
The Department of Housing states that primary responsibility for Building Regulations compliance rests with designers, builders and building owners. Technical Guidance Documents provide recognised guidance on how the requirements can be achieved in practice.
Within that framework, specialist passive fire knowledge can help resolve the practical interfaces between the fire strategy and the services passing through fire-resisting construction.
On many projects, the most difficult problems are quite ordinary: an opening that has grown beyond the original detail, services arriving too close together, containment preventing access to a compartment wall or work becoming concealed before it can readily be inspected.
These are construction issues as much as fire stopping issues, and they are generally best addressed while the design and coordination process still allows adjustments to be made.
How Can Flame Stop Assist at the Design Stage?
Flame Stop works with architects, engineers, fire consultants, contractors and clients on passive fire protection Ireland projects, including apartment developments, housing schemes, healthcare facilities, commercial properties and refurbishment works.
Where a project involves complex compartmentation, congested service zones or significant service penetrations, Flame Stop can provide building analysis, survey input, tender preparation and practical fire stopping advice before those details become fixed on site.
