Fire Safety Engineering
Creating safer buildings. Unlocking ambitious design.

The Challenge
Complex buildings rarely fit standard answers.
Every building presents a different combination of people, uses, materials, layouts, and risks. Standard guidance provides an important starting point, but it may not always reflect the complexity of an innovative design, a technical challenge, or a building with unusual operational requirements.
Without the right expertise at the right stage, fire safety can become a source of uncertainty and project risk. Design aspirations may be restricted, approval can become more difficult, and unnecessary measures may add cost, complexity, and delay.
Our challenge is not simply to demonstrate compliance. It is to develop a fire safety approach that supports the wider design of the building and remains practical throughout construction and occupation.
How Tenos Helps
A clear strategy from the first concept to completion.
Feasibility and concept advice.
Identifying fire safety requirements, risks, and potential design constraints before they become embedded in the project.
Design team support.
Working collaboratively with architects, engineers, developers, and contractors to ensure fire safety is coordinated with the wider design.
Fire safety strategies.
Developing a clear, coordinated strategy that defines how the building will protect occupants and satisfy relevant requirements.
Fire strategy drawings.
Translating the strategy into clear, detailed visual information that can be understood and applied across the project team.
Advanced engineering solutions.
Using modelling, calculations, and specialist analysis to assess complex scenarios and support designs that move beyond prescriptive guidance.
Approval and construction support.
Engaging with approving authorities and providing technical advice as the design develops and work progresses on site.
Why choose Tenos?
Fire engineering that goes beyond compliance.
Preserve design ambition.
We explore how fire safety objectives can be achieved without compromising architectural intent, functionality, or the experience of the building’s occupants.
Gain clarity earlier.
Early fire engineering input can identify risks and opportunities before they become expensive or disruptive to address.
Avoid unnecessary complexity.
Our engineers focus on solutions that are safe, common sense, evidence-led, and proportionate to the building and its risks.
Support statutory approval.
We develop credible, clear, practical technical justifications and engage constructively with the relevant approving authorities.
Make more confident decisions.
By considering fire safety alongside design, construction, operation, and commercial realities, we help clients understand the implications of each decision.
Protect people and assets.
Our work begins with life safety, while also considering property protection, resilience, and, where required, the building’s long-term performance.

FAQ
Frequently asked questions
When should a fire engineer be appointed?
Ideally, during feasibility or early concept design. Early input makes it easier to identify potential constraints, influence important design decisions, and avoid expensive design changes later in the programme.
What is fire safety engineering?
Fire safety engineering applies scientific and engineering principles to develop appropriate measures to protect people, buildings, and assets from fire, allowing fire safety to be considered as a complete system.
Does every project require a bespoke fire safety strategy?
The scope will depend on the building, its use, complexity, and applicable requirements. Complex, innovative, non-standard buildings are particularly likely to benefit from a coordinated strategy developed around their specific risks and design.
Can fire engineering help preserve the original design?
Yes — early engagement with a fire engineer can help identify ways to meet fire safety objectives while retaining important architectural features, spatial arrangements, and functional requirements.
Can Tenos liaise with approving authorities?
Yes. We are happy to communicate the technical basis of the proposed fire safety approach with regulators, whether during design or construction.
Can Tenos remain involved during construction?
We can. Continued involvement helps Tenos work with the project team if the design changes, if clarity on the intended strategy is required, and to advise whether the as-built construction meets the original design intent.
What is the difference between a fire safety strategy and advanced fire engineering?
A fire safety strategy defines the overall approach for the building. Advanced engineering provides specialist evidence, calculations, or modelling where more detailed analysis is needed to understand performance or justify a particular solution.
