We areGlobalBoth WSP and Parsons Brinckerhoff have stellar brands within given market sectors and geographies, and we must capitalize on those brands. Therefore, and until further notice, we will beone company with two brands: WSP and Parsons Brinckerhoff. However, we will use the two brands, side-by-side, when we are working together strategically on business development, bids, conferences, or in our global corporate material. Guidelines onhowto use the co-branding will beconveyed to you shortly, and we will continue to engage you on this important topic.

We are future readyOur Future Ready programme is a global innovation programme launched across our business in 2014.WSP | Parsons Brinckerhoff’s “Future Ready” initiative is a global innovation programme. It gives our staff a consistent understanding of what we believe a future world will look like and challenges them to design to this model, within current code regulations. “Future Ready” ensures that sustainability is a central consideration from the outset and focuses on the impact that dwindlingresources, climate change challenges, security concerns, population changes and technological innovations will have on our lives far into this century. The programme enables us to work

Our projects span a diverse range of sectors from industrial facilities to government and commercial property developments, mass transit and infrastructure. We are global leaders in the safety design ofhigh-rise buildings, large retail schemes, complex tunnel projects and transport interchanges.

Theoretical knowledge combined with practical

application

Our skills include code consultancy, the development of holistic fire safety strategies, fire risk assessments and analysis, fire system design and specification, value engineering exercises and peer reviews. Using advanced computer modelling of fire, smoke, evacuation and structural response, we combine theoretical knowledge with practical application.

IntroductionWe provide practical and cost-effective design solutions to protect people, property and the environment from the destructive effects of fire.

Project-specific solutions

With a global network of qualified and experienced fire engineers, we add unrivalled expertise and experience to the knowledge of local specialists to develop innovative and project-specific solutions that help clients achieve their aspirations. This includes introducing complex fire engineering strategies where standard code requirements may present obstacles, with respect to the project vision, cost or function.

Our solutions allow clients to meet the highest safety standards and satisfy their legal obligations, while also offering design flexibility and savings in terms of budget and construction program.

How we support our ClientsWe are able to support and protect our Clients operations through the application of a range of innovative procedures & design standards, including:

Project CaseStudiesKVV8 at Värtaverket site in StockholmClient: FortumCapacity: 1700 GWh heat and 750 GWh electricity per year

KVV8 is a biomass fueled power and heat plant at Värtaverket. At the site there are several other power and heat plants as well, some with an ongoing conversion from fossile fuel to biomass by increasing the proportion of eg. olive kernels in coal. For KVV8 WSP has performed the following:

• Overall fire engineering strategy and performance based justification of deviations

• Extinguishing systems• Fire safety in tunnel from surface to underground storage facility beneath the

Värtaverket site• Residual fire water investigation• ATEX (explosion protection document including risk assessment and

classifica- tion plan) for inner and outer handling of flammable gases and liquids

• ATEX for inner and outer handling of combustible dusts (eg. coal, bark, woodpellets, saw dust, wood chips, willow, peat) from ship or from the unloadingof crushed olive kernels from train

• ATEX and the handling of ammonia (25 vol%) to the gas treatment facility• Oil/spill water separation tank located in the plant’s oil storage terminal• Risks associated with the development of carbon monoxide and carbon

dioxide• in the underground storage facility for KVV8 aiming to prevent poisoning• Operational intervention plan for the site, in close cooperation with local fire

authority• Continuous inspections on-site and fire safety strategy during construction

period• Permits for the handling of flammables• AutoCAD drawings for all of the above where applicable• Seveso related documentation

Project CaseStudiesIgelsta KVV in SödertäljeClient: SöderenergiCapacity: 200 MW heat and 85 MW electricity

• Overall fire engineering strategy and performance based justification of deviations

• Extinguishing systems• ATEX (explosion protection document including risk assessment and

classification plan) for inner and outer handling of flammable gases and liquids• ATEX for inner and outer handling of combustible dusts (eg. bark, saw dust,

Brig y Cwm Energy from Waste FacilityWSP supported Covanta Energy in producing a Fire Strategy for the proposed Brig y Cwm Energy from WasteFacility. The scheme involved justifying extended travel distances on the access gantries of the main facility anda viewing platform c.35m- high around the facilities stack that is served by a single stair.

Bradford and Calderdale Resource Recovery FacilityWSP (Fire Engineering) has provided support to the Bradford and Calderdale RRF in reviewing the required fire safety meas- ures taking account of standard guidance, industry approved/standards and insurer recommendations. This included the use of event trees to make a detailed analysis of what measures were suitable in providing the best cost benefit to reduce risk throughout the facility.

Global Switch 2, East India Dock – Structural Fire Resistance reviewOn this development the rooftop plant floors were strengthened to accommodate a new floor (Level 14) containing three generators. There were difficulties in applying 120 minutes fire protection, in accordance with the guidance set out in Approved Document B (AD B) and WSP Fire were asked to review whether the Functional Requirements of Part B of the Building Regu- lations could be met in some other way. Following a quantitative and qualitative review WSP Fire were able to remove the need to apply structural fire protection which reduced costs by more than £140,000 and shortened construction time by 2 weeks.

Blyth SGT 5 & 6The project initially involved a fire risk assessment of the fire hazards presented by transformers. WSP fire engineers analysed and assessed, in detail, the potential impact of a transformer fire. This included a brief review of the national grid guidance document, NGTS 3.1.3.

Grendon SGT 1 ReplacementA preliminary study and fire risk assessment was undertaken to assess the fire risks presented by the SGT 1transformer and its associated fire damage zone. The fire engineering assessment identified the magnitude ofrisk to allow a consequence assess- ment to be carried out against the perceived hazard level.

National Grid 3.1.3 Code ReviewInitially WSP provided a review of the current guidance used for the designing of transformers in relation tofire safety. Follow- ing the review a number of changes to the guidance were proposed including thereduction of fire separation distances and the layout of fire barriers.

Ridham Dock Biomass FacilityWSP have provided a number of services to the proposed Ridham Dock Biomass Facility including fire engineering support. More specifically WSP have following consultation to set out the design scenarios and acceptance criteria, completed a number of technical calculations for the Boiler Hall and Turbine House to determine smoke ventilation system requirements.
