Of all the responsibilities facing the property industry, keeping people safe from the dangers of fire and smoke is among the greatest. Part science and technology, part psychology, part management and law, this field requires rigorous mastery of all aspects of emergency planning, fire protection engineering, security system design and building and fire codes, while also ensuring clients realize their architectural vision and operational goals while meeting their responsibilities.

Efficient Delivery: Connectivity, Collaboration & Diversity

WSP’s fire engineering community consists of 250 experts worldwide who work in close collaboration, sharing best practice and knowledge. Our mission is to deliver quality, innovation, and value to our clients by understanding how to integrate fire safety in the design process in relation to local conditions and codes. Rob Davies, who heads up WSP Fire in the Middle East, said “we are proud to have a talented pool of fire engineering experts with international and highly specialised experience including with CFD (Computational Fluid Dynamics), human behaviour, hazardous materials specialists and façade materials, on some of the world’s most renowned buildings.”

Fire safety cannot be understood in isolation and the combination of our global expertise and relationship with other WSP disciplines brings additional dimensions to our work providing an efficient project delivery model and bring commercial benefits for clients. 

Across the globe we provide a broad range of services to deliver fire-safe buildings that are also functional and economical. These include the development of fire safety strategies, fire engineering design and specification, fire safety audits, fire risk assessments, computer simulation for fire dynamics, value engineering exercises and peer reviews. 

Our role is to apply scientific and engineering principles, rules and expert judgement based on our understanding of how fire impacts a building, the interaction with human behaviour and how to ensure safe access for fire fighters. We combine theoretical knowledge and practical application, using advanced computer modelling of fire, smoke, evacuation and structural response. In some regions, we also provide fire safety systems design and post-occupancy safety solutions.


Diverse Project Experience

We provide fire engineering services to some of the world’s leading architects, developers, engineers and planners, across an enormous diversity of projects. These range from the 519m Tianjin CTF-Binhai Centre, one of China’s tallest towers, to the European Spallation Source in Sweden, which will accommodate the world’s most powerful neutron source. Our work also encompasses numerous government properties, commercial and residential developments, large retail schemes, airports, stations and other transport interchanges.

Scale isn’t always the most challenging; WSP is highly regarded for its specialist technical skills in the delivery of highly sensitive, controlled environments for facilities such as laboratories and warehouses. For examples, The European Spallation Source, a multi-disciplinary research centre based on the world’s most powerful neutron source and one of the largest science and technology infrastructure projects being built today, is a very complex development with offices, conference areas, industrial sections and a long tunnel – all requiring very different fire and risk strategies. In addition it’s also a nuclear facility. We’ve also carried out smoke and fire modelling, structural analysis and evacuation modelling, integrating many different software.

Interaction with Designers and the Planning Authorities

Given that fire engineers are responsible for the fire safety strategy of a project, our work informs the whole design team on fire safety matters. It provides design guidance to architects, advises the building services engineers on what systems are required, such as smoke ventilation, fire dampers, fire detection, smoke alarms, emergency lighting and sprinkler systems, and provides vital information to structural engineers on how long a structure must be protected and how that is achieved.

The fire strategy is also a key document used by authorities to base their decision on for approving the safety aspects of a building. One of the most important aspects of our work is to liaise with building authorities as a scheme develops to discuss fire safety aspects, demonstrate that the strategy is safe in different scenarios and eventually gain approval for a fire-safe building that also meets its aesthetic, functional and commercial objectives.

A Tailored Discipline Which Encourages Creative Design

Fire engineering is a customizable discipline in which, while the science is universal, the approach depends on the type of building. The risks are different on every project. For example, in the case of Glasgow’s Queen Elizabeth Hospital, WSP had to consider the special conditions of a healthcare environment where many patients would be unable to evacuate wards unaided in an emergency. By contrast, we are also involved in a number of airports worldwide, including projects in Bahrain, Qatar, Chile and London Heathrow, where keeping the airport operational to enable planes to keep landing and people moving through the buildings is a priority. In addition, fire engineering allows clients and architects to realize their creative design aspirations and to incorporate unique features, while still meeting the intent of regulations.

“Fire engineering is bespoke to each individual project, and depending on what the project is and what the client aspirations are, the outcome will be different,” says James Boyes, Director of fire engineering in Australia and New Zealand. “For example, the fire strategy for an airport might focus on business continuity. The building needs to continue operating during an emergency because planes need to keep landing and people need to keep moving through the airport. Performance-based design enables us to develop a solution and scientifically prove that it will work.”

Interpreting Code and Performance-based Design 

Fire precaution measures can be a large investment in any project due to the capital cost but also due to the potential loss of an efficient building design, such as floor space or staircases. It is also however, one of the most important investments that can be made in order to protect people and property from the dangers of fire. Combining theoretical knowledge with practical application, WSP is able to deliver optimal, performance-based designs.

The construction industry worldwide is subject to strict legislation governing fire safety. One of our tasks is to help building owners to understand and interpret the complex codes which vary from country to country and from sector to sector. In healthcare, for example, a project may have to comply with up to three different sets of codes.

For many projects, particularly non-standard developments, which may be large and complex and with high occupancy levels, standard code requirements may be inadequate, or may present obstacles with respect to a project’s vision, cost or function. Through the application of performance-based design, we can scientifically demonstrate that alternative solutions will achieve the same performance objectives as the code by calculating the building’s behaviour under realistic fire scenarios. This can add significant value to a project.

Our innovative, cost-saving fire engineering techniques allowed for a 50% reduction in the number of escape cores for the Manchester Hilton. In the case of the Al Shaqab Equestrian Centre in Doha, by undertaking thermal analysis of the steel structure of the huge 350m x 150m roof structure spanning the arena, we demonstrated that the life safety provisions of the code could be met without the prescriptive requirement to apply expensive fire protection to the roof members, resulting in significant cost savings.


Keeping-up with Changing Environments

As buildings are required to be more flexible and reflect potential changes in use, innovative fire designs must be adaptable. Research into such designs is a significant part of fire engineering as well as new codes, materials and rapidly evolving technologies. WSP has paired up with universities to research topics such as fire retardant and sustainable materials, fire models for the urban built environment, new fire suppression technologies and lift evacuation strategies. Wayne Bretherton, Director of Property and Buildings ANZ at WSP comments that "modern materials can have unintended consequences. In terms of fire when a material comes to market there needs to be a proper assessment of how it is developed and used”, highlighting the critical role research plays in ensuring we design futuristic and safe fire engineering solutions for our communities. WSP’s role in such research is to bring industry experience and act as a link between the academics and industry.
