BRIDGES
From the highest profile bridge in a metropolis to the smallest culvert in a wider masterplan, our passion for high quality design that directly meets the needs of our clients remains unchanged. From concept, through design and planning – to construction and aftercare, we support our clients every step of the way.
More than any other area, bridge design gives us the chance to use all of our skills to create structures which look good, work well and fit into their settings. Bridges have their primary functions – to carry people, cyclists, vehicles, trains and even gas, electricity and water over obstacles – but they are also extremely visual objects which attract attention. Unlike buildings in which structural elements are routinely concealed by cladding and facade, it is often possible to see exactly how a bridge has been constructed. Our bridge engineers are skilled at coping with challenging sites, timescales, budgets and designs to bring the best out of every project. The bridges and civil engineering structures team at BuroHappold Engineering are experts in the design, construction and maintenance of bridges, tunnels and complex highway structures. Our fluency and knowledge of the design process, along with our experience of liaising with local authorities, planning and heritage agencies, architects and contractors, ensures that we can deliver practical infrastructure solutions which meet the aspirations of our clients.

We regularly take projects from initial concept through detailed design and testing, planning and approval processes to construction and completion. We are equally able to apply our expertise in the testing, remediation and repair of existing structures; adding many years of life and reducing cost to owners and operators. On protected or heritage sites we bring detailed knowledge of the options and approaches which can be used to ensure that all construction adds to and enhances its surroundings. Through our construction programmes we have protected sensitive ecological sites, designed structures which transfer no additional pressure to fragile historic buildings, created bridges that appear to vanish into their surroundings and successfully developed landmark structures which breathe new life into their settings. Operating at the forefront of bridge design, we apply the latest technology and approaches to overcome the unique challenges of our projects. We have created bridges with huge spans, reduced the size and mass of structural elements without compromising strength and have integrated flexibility and sustainability in new and surprising ways. Prefabrication enables us to design structures which
can be constructed quickly, with a better guarantee of quality. Detailed testing and analysis allows us to create structures that are able to cope with severely constrained or difficult sites, restricted budgets and tight construction timescales. Our pragmatic approach to projects ensures that we always deliver excellent quality and value. Even on high profile, iconic new structures, we ensure that we have clearly identified what we can do to create real and lasting value. At all levels our intelligent design produces cost effective solutions. Through our innovative use of materials and advanced structural analysis we deliver civil structures which are truly awe inspiring. We have built up a reputation for expert engineering skills and creative flair on high-profile projects worldwide. Along the way we have forged strong working relationships with many leading bridge architects and have been successful in international design competitions, producing elegant and economical solutions that fully realise our clients’ visions. This work has been recognised by the winning of many awards for design excellence.

BREATHTAKING STRUC TURES AND SUBTLE BEAUT Y Much more than a route from A to B, a landmark bridge can define its setting and create and communicate identity, offering people new ways to enjoy and interact with their environment. Our skill in manipulating new and traditional materials enables us to work alongside the world’s best designers and most ambitious clients, pushing the boundaries of aesthetic design, to create structures which define new standards. Iconic structures such as Ponte Della Musica, Alexandra Arch and the High Line offer people the chance to enjoy views they have never seen before – they frame the landscape and illuminate the night. Their instantly recognisable forms attract attention, create interest and compel visitors to their locations.
Our award winning team works in partnership with the client, construction team and local regulators to ensure that the bridges they create are not only beautiful, but that they function beautifully as well. Expertise and meticulous attention to detail ensures that every opportunity to improve form and function is identified and put into action. Well designed bridges can act as a catalyst for local growth and regeneration. For example the King Abdul Aziz Flyover supports commercial growth by massively improving traffic flow in central Riyadh.

THE SACKLER CROSSING London, UK The Sackler Crossing, designed in collaboration with John Pawson Architects, plots a serpentine path over the Lake at Kew Gardens, establishing clear visual connections with the repeating natural forms of its setting. The most striking element of this deceptively simple structure is the flat bronze posts which edge the black granite walkway. As visitors approach the crossing these appear as a solid wall, but viewed sideways they almost disappear into their surroundings. At night, almost 1,000 white LED lights illuminate the crossing and reflect on the water. The architect’s vision was to deliver a bridge that would form an integral component of a new route through

previously under-used areas of the gardens, while creating a striking contemporary landmark. A key challenge in realising this was the client’s requirement for the 70m long structure to be sleek and unobtrusive, while set as close to the lake’s surface as possible. BuroHappold’s team used a slender steel framed support framework to achieve this architectural imperative. The bridge is constructed using just two visible materials – bronze and granite – each chosen for their hardwearing qualities and the way they complement the landscape. The steel framework is concealed from view, and is bolted down to concrete piers spaced across the lake at approximately 8m intervals.
In order to meet the very tight construction timetable set by the client, our team assembled the crossing while the lake was being drained for dredging in preparation for the spring nesting season. Since completion in 2006, the Sackler Crossing has received widespread praise and awards including the 2008 Stephen Lawrence Prize, RIBA National Award, 2008 Footbridge Award and two lighting awards.

KING ABDUL AZIZ FLYOVER Riyadh, KSA Crossing the King Abdullah Road intersection at the heart of Riyadh’s thriving commercial district, this new sixlane flyover will carry tens of thousands of vehicles each day. Designed by our engineers to blend harmoniously into its modern surroundings, this elegantly simple structure comprises a steel feature arch, rising 30m in the air to support an extensive deck. The bridge needed to accommodate three lanes of traffic in each direction so our team proposed an “orthotropic” deck, where the steel load carrying deck is stiffened in two orthogonal directions, a very efficient and light way of carrying traffic loads. The deck is supported by a cable system suspending from a single fabricated steel arch, creating a unique visual focus. Piers support the arch, which itself supports the approach deck, via two independent bearings. The flyover has been designed to KSA standards in conjunction with AASHTO LRFD.

The bridge was constructed above a major road in Riyadh which had to remain in use. This severely limited our access from beneath so we developed a construction plan using the span by span method. This technique enabled us to build out from the ends, with the installation of each new span supported by the previous one, ensuring safe passage for the traffic passing underneath.

ALEXANDR A ARCH Singapore Commissioned by the Singaporean Government in 2003, BuroHappold provided concept and detailed design for this stunning bridge. Designed to resemble an open leaf, Alexandra Arch beautifully complements its forest location on the Southern Ridges trail. We worked with LOOK architects, EcasEJ Consultants and a local engineering firm to create the bridge, a commission won through an international design competition. The impressive structure carries pedestrian and cycle traffic across a 6 lane highway and functions as part of a much larger ensemble with the elevated walkways and nature trail.
The bridge’s curved deck is supported by hanger fins and intersects a single leaning arch, tilted at a 70° angle. Our team created a granite-surfaced deck which acts as a torsion box, effectively concealing the support structures to maximise aesthetic appeal. The bridge’s eye-catching arch rises 17m above ground level; a visionary design feature making it a unique element in the landscape. At night the gleaming white structure is lit by a spectacular display of LED lighting which moves through a spectrum of sunset inspired colours. In accordance with the clients ideals our designers were conscious of the need to maintain a tight control on budget.
The engineering design was a careful balance between optimisation for structural efficiency and rationalisation for construction guaranteeing maximum costeffectiveness. Durability and long term maintenance issues were also key drivers for the design. These were addressed through careful choice of material, detailing and projection system. Construction started in Summer 2006 and the bridge was opened to the public on May 10th 2008 by the Prime Minister of Singapore, Lee Hsien Loong.

PONTE DELLA MUSICA Rome, Italy Ponte Della Musica, a dual purpose pedestrian and public transport bridge crossing the substantial River Tiber in Rome, opened in mid-2011. It is the first such crossing to span the Tiber since Roman times and exists as a stunning symbol of advances in design and technology. Working with Powell-Williams Architects, BuroHappold developed the concept design, then oversaw detailed design and construction, which was undertaken by the design and build contractor. This major crossing joins the banks of the River Tiber between the Foro Italico and the area of Flaminio. The bridge is a key element of the Rome city plan which involves the development of a new east-west axis along the Via Guido Reni on the east bank of the Tiber. It connects various cultural and sporting facilities of the Flaminio district with the Olympic stadium and other sports facilities on the west bank in Monte Mario. Our striking design incorporates two inclined steel arches supporting an expansive steel deck.

GREENSIDE PLACE LINK BRIDGE Edinburgh, UK BuroHappold worked closely with Broadway Malyan Architects to design a new multi award winning pedestrian bridge spanning 50m over Leith Street in the heart of Edinburgh’s city centre. Due to its prominent location, connecting Edinburgh’s principle covered shopping centre to an extended Nottingham car park terminal, an important aspiration for the client was that the bridge provides spectacular views of the city and is itself visually compelling. In accordance with these objectives, our engineers used sophisticated modelling techniques to create the complex geometry of the bridge’s attractive S-shaped curvature. Constructed from glass and a distinctive interlocking helical steel frame, pedestrians crossing the sweeping deck experience a light, open space affording stunning views of the surrounding city. The structure’s unique shape enables it to curve around a building which stands between the shopping centre and car park, and also provides an appealing design feature. Supported by slender V-shaped columns, the bridge’s gradient has been calculated to facilitate effective drainage and also to deceive the human eye into registering it as perfectly flat against the horizon.

MOBIUS BRIDGE Bristol, UK BuroHappold worked together with Hakes Associates on this design inspired by the concept of an endless Mobius Loop. Providing a new pedestrian and cycle crossing to connect Bristol’s new Finzels Reach development with the city’s main park, Castle Park, this beautifully lit, iconic bridge will create an instantly recognisable landmark. Our design exhibits an intriguing mix of simplicity and complexity. The deck, arch and pier are one and the same, giving the structure an economy and lightness. The site has archaeological significance, so a traditional bridge design with walkways reaching out into the banks could not be considered. The geometry of the Mobius bridge avoids the transfer of any additional weight onto either bank, instead using
new supports concealed just inside the harbour wall. In order to create the impression of a free-floating form resting on the surface of the water, the design team suspended the 60m deck by relatively small diameter hanger cables to reduce visual obstruction. There is a connection between the arch and the deck where the two cross over and the deck section spans to its conclusion as a beam. The Mobius Bridge was designed to become a stunning symbol of the regeneration of the Bristol Harbour area and an integral part of its identity.

CANFORD FOOTBRIDGE Dorset, UK BuroHappold developed both concept and detailed design for this replacement cycle and footbridge, connected to an existing Grade II listed masonry arch bridge, near Wimborne in Dorset. Working with contractor Carillion, we constructed a new steel structure which runs alongside and is supported by the existing bridge, dating back to 1813.
To protect the historic structure, we carefully analysed the lateral and eccentric loads imposed by the new bridge. We then undertook careful and unobtrusive strengthening of the existing arch, adding slender steel supports alongside to provide an acceptable load path to the shared foundations. New piled foundations supplemented the existing foundations, which are located in a river and a flood plane.

THE HIGH LINE New York, NY, USA Built in the 1930s and last used in 1980, the High Line was a little known and long abandoned elevated railroad, spanning Manhattan’s meat-packing district, when an initiative to determine the fate of the line began in 1999. Demolition seemed imminent when BuroHappold, working with James Corner Field Operations, was selected by the Friends of the High Line and the City of New York to create a master plan for the re-use and re-integration of this expanse of railroad. Inspired by the wild beauty of the derelict line, the team successfully re-imagined this section of industrial infrastructure as a place of leisure, city life, and nature; mitigating the need for demolishment
while enriching people’s lives. Many of the original steel rails were restored and re-used reducing costs and environmental impact. The High Line is now home to 210 different species of native perennials, grasses, shrubs and trees. BuroHappold created two structures which pushed the concept of the High Line even further – the Flyover, an elevated steel walkway which floats 8ft above the main walkway, and the Cutout, a steel mesh deck providing views, through the original rail structure, to 30th street below.

PRINCESS ROYAL FOOTBRIDGE Thorne, UK BuroHappold worked with Broadway Malyan and Thomson Engineering Consultants to design and construct a new footbridge across Stainforth and Keadby Canal in Thorne. To satisfy the strict requirements of British Waterways requiring the canal to be navigable at all times, we designed a 16m long asymmetric swing bridge. This solution helped to ensure that the route remained as level, and therefore as accessible, as possible. The novel design of this bridge sees the relocation of the pintle to above and to the side of the deck, rather than directly below as normal. This allowed us to create a feature counterweight at the side of the bridge.
A important concern for the client was that the footbridge allowed for safe, comfortable passage of pedestrians and cyclists. Our response was to design a wide, easily accessed deck, supported by cross members which are cantilevered from a single longitudinal tubular beam. The bridge can be opened by a hydraulic mechanism housed in an enclosure, countering any restrictions to elderly and disabled persons using the facility. Completed in 2005, the bridge won a commendation in the ‘Community’ Category in the Waterways Renaissance Awards and has proved extremely popular with residents.

walls had to be constructed within 70mm of the shallow foundations of the flyover, which remained in use throughout the build. Combined with limited clearance under the bridge, this presented severe geometrical constraints and restricted the choice of construction plants and methods which could be deployed.
BuroHappold were commissioned by Saudi Oger Limited to design three cut and cover tunnels for Phase 1 of the project. The construction was subject to strict time constraints so it was vital that an efficient solution was realised. Our design offered several advantages including speed of construction thanks to the precasting of the tunnel roof and also a reduction of future maintenance requirements by removing the need for bearings and movement joints.
Our solution was to introduce a piled load transfer structure which limited movement of the flyover to insignificant levels. We also utilised sophisticated monitoring technology to assess the stability of the flyover during construction, mitigating any risk to the project as it evolved.

CALDON CANAL BRIDGE Staffordshire, UK Caldon Canal footbridge was the first element to be completed in a masterplan for the redevelopment of the area just south of Hanley city centre, by RENEW North Staffordshire. The masterplan will create an outstanding waterside development, incorporating new residential housing and leisure facilities and refurbishing the famous Bridgewater Potteries. We provided specialist engineering design to architects NORD on this innovative and eye-catching structure, which uses light and form to delight passers-by, both on land and water.
The bridge was given special emphasis within the masterplan. Conceived as a social space where walkers will enjoy views across the canal basin, our high quality design sets the tone for the wider development, creating a visually stunning structure with some unique elements. Most people will view the bridge from below. With this in mind our team designed an elaborate underside which displays bespoke geometric patterns by NORD, inspired by the industrial history of the area and derived from 19th century ceramicist Thomas Minton. This element is formed from a diagonal grillage of steel beams with custom-made aluminium
coffers between them, giving visual emphasis to the structure. Our unique vision also included a cantilevering glass balustrade providing edge protection and an unusual arrangement on the south bank of the canal where the abutment appears to just touch the bridge deck without any visible support.

Many of our bridge and tunnel projects are delivered as elements of wider masterplans and regeneration projects. A high quality bridge, or a new connection in just the right place, can provide the key to unlocking potential in developments and areas. Often bridges and tunnels do not just move people between different points, they add definition and identity to areas which have struggled through economic downturn, providing focal points for regeneration and renewal. On masterplan projects such as Zhuhai New City and Sabah Al Ahmad Sea City bridges, tunnels and culverts create the networks which will support the lives of
new communities, directly contributing to the success or failure of these major developments. We recognise that development cannot be at the expense of our fragile ecology, so we combine cutting-edge technology with age old understanding to protect environments such as Hayle Harbour and to embed sustainability, as at Bruckenhafen.

Working with contractor Sir Robert McAlpine, our team delivered concept design then oversaw detailed design and construction of the bridges, which had a total construction value of £15m. Our specialist crowd flow analysts undertook a comprehensive study, prior to completion of the detailed design and construction drawings, to optimise user experience. As part of our role we led the process of securing planning and technical approvals.
A key concern for our client was that the commuter and freight railway lines passing beneath one of the bridges would need to remain functioning during assembly. Our solution was to design the bridges as steel framed structures that could be lifted or “launched” into position. This approach enabled us to mitigate disruption to the lines and we were able to fully satisfy operators Network Rail & London Underground Ltd that the work posed no risk to rail traffic and people below.

Working with FSP Architects, then later with Feilden Clegg Bradley Studios, we designed a slim concrete deck with edges angled to catch and reflect the light. An aluminium balustrade, which appears deceptively delicate, spans the length of the deck. The aim was to create the impression of a fine white line crossing the water, causing minimal obstruction to views of the existing swing bridge and nearby church. The site also has sensitive ecological conditions, including valuable spawning areas for fish and habitats for shellfish and grey seals. We worked in partnership with the local authority and environmental agencies to create a detailed construction plan. This outlined how we could avoid
unnecessary dredging and maintain the natural tidal pattern throughout the process. In addition, we designed an environmental barrier to keep wildlife safely clear of the area during construction.

CHARLES RIVER BRIDGES Boston, MA, USA Described as ‘the largest, most complex and technologically challenging highway project ever attempted in American history’, the Central Artery / Tunnel (CA/T) Project was a hugely ambitious endeavour. The initiative aimed to reduce traffic congestion, improving Boston’s environment and creating new parklands along the north and south banks of the Charles River. We undertook the concept and scheme designs for two pedestrian and cycleway bridges on the north and south banks of the Charles River. We also carried out an independent check of the detailed design of the north bank bridge.

SHIZIMEN BRIDGE Zhuhai, China With a site area of 2,500ha and a current population of around 40,000 people, Zhuhai New City is an expanding eco-city, located in the North West of China. Working with Barton Willmore, BuroHappold developed a masterplan for the city. Our specialist bridge engineering team designed five road bridges as part of a major infrastructure package. The largest of these bridges is Shizimen Bridge, a landmark structure which will be highly visible from Zhuhai to the north and Macau to the East. Subject of an international design competition, our winning submission was developed in collaboration with 10 Design architects. Inspired by the undulating coastline, the design uses two arches and suspension cables to support the deck, which carries three lanes of traffic, plus cycle and
pedestrian paths, in each direction. The larger arch spans approximately 190m and stands 100m high, crossing the deck diagonally. The smaller arch runs parallel to, and is offset from, one side of the deck. The arches connect beneath the deck to form one continuous form lightly touching the water part way across the river. The simple, elegant structure makes a strong formal statement and, when reflected in the water, creates a figure of eight, a sign of prosperity in Chinese culture.

STRATFORD TOWN CIT Y LINK London, UK BuroHappold undertook the detailed design of this landmark structure which forms the gateway to the Stratford City development in East London. The 12m wide pedestrian bridge was designed to cope with crowd flows of up to 80,000 people per hour during the London 2012 Games. It crosses eleven railway lines, including Network Rail and London Underground, plus the platforms of Stratford Regional Station. The bold decision to combine weathering steel with a high quality glazed facade created a sophisticated urban appearance and a virtually maintenance-free structure, which will form a dark brown patina over time, giving the bridge a pleasing natural appearance. A fundamental complication on this project was the lack of assembly area on the station side, a very limited footprint within the Stratford City development and no suitable locations for heavy cranes to be located. We adopted an innovative approach, installing a launching nose and tail frame, then sliding the first 48m bridge section into position with strand jacks and low-friction skates providing support. This resulted in the first known live bridge launch over an operational station in the UK, avoiding disruption and inconvenience to passengers.

WEST KOWLOON TERMINUS Kowloon, Hong Kong The West Kowloon Terminus is an underground station located immediately north of the proposed West Kowloon Cultural District, close to Lantau Airport Railway Station and Kowloon Southern Link Austin Station. This is also the most southern terminus of the national high speed rail network. The terminus will be served by seven footbridges at Level 1, providing connections between the station retail floor and surrounding buildings. BuroHappold’s bridge team adopted an innovative approach by incorporating nature into the design. Two types of footbridge were conceived – tubular
steel enclosed structures which include travellators, and reinforced concrete open deck bridges. All open deck bridges feature planters and canopies to make the environment feel like a garden. Two also include planting areas and fixed seating to serve as a public leisure space. Aligning nature with form creates a unique, visually appealing structure which integrates well with the surrounding green space. We also provided a solution to the problem of noise arising from the location of one bridge next to a busy junction. Our design featured acoustic barriers and a skylight to let light in, but keep noise and pollution out.
West Kowloon Terminus is destined to become a major gateway to the Chinese mainland, with distinctive architecture, landmark features and a user-friendly layout, accommodating immigration and quarantine facilities and Hong Kong Special Administrative Region and Mainland Customs.

KING ABDULLAH FINANCIAL DISTRIC T, SKY WALKS Riyadh, KSA BuroHappold is working with Henning Larsen Architects on a major project to create a sustainable new city in Riyadh, designed around pedestrians instead of cars. Car parking has been kept to a minimum and a monorail serves six stations in the financial district. A network of secured acclimatised pedestrian bridges, Skywalks, connects these stations to all buildings in the new development. The Skywalks are placed at level 1 elevating them above street level. After entering the Skywalk system through a security checkpoint, pedestrians can move freely through the various buildings and bridges, enabling quick and comfortable passage across the streets below.
38
BUROHAPPOLD ON BRIDGES
Designed to function like traditional streets where people can meet and interact, individual Skywalks range from 20m to 70m in length and are either four or six metres wide. Within each connecting tower, there is a public connection to ground level and a range of services, such as cafes and small shops. To cope with Riyadh’s intense heat, we anticipate a large number of pedestrians choosing the secured acclimatised environment provided by the Skywalks once the city is fully occupied. Our expertise has reduced the environmental impact of the project with measures such as building orientation and the use of specialist cladding materials and shading, to reduce heat gain.
Using state of the art analysis and BIM technology, we were able to complete the design of more than ninety Skywalks in less than six months reducing costs to the client. A full scale mock-up allowed us to test integration and the practicality of assembling components, guaranteeing their success, before full production of the Skywalks structures commenced.

SABAH AL AHMAD SEA CIT Y BRIDGES Kuwait BuroHappold is providing a full multi-disciplinary service on the Sabah Al Ahmad Sea City development 85km south of Kuwait City, which will eventually become home to over 100,000 people. Alongside masterplanning, civil engineering and other services, we are delivering detailed design and construction supervision on a number of reinforced concrete culverts, bridges and tidal gate structures. Our team designed two adjacent and complementary bridges in collaboration with Powell-Williams Architects. Both are 125m long and consist of five spans of pre-stressed, pre-cast concrete beams with an insitu concrete deck, but they perform different functions. The first carries the major services to the development, while the second carries vehicles, cycle and pedestrian traffic. The service bridge is 12m wide accommodating 80 ducts, an 11kV electricity cable and over a dozen large diameter pressurised pipes. The ambitious road bridge is 40m wide with six traffic lanes and two pedestrian footpaths. Careful coordination was of paramount importance and fundamental to our approach, ensuring that services which were critical to the wider construction programme could be installed first. Our design for the service bridge, unconstrained by the requirements of a safe vertical highway alignment, also softens the visual impact of the road bridge by providing an aesthetically pleasing vertical curvature. In addition to these bridges, we have two more bridges ready to start construction, two in design and more planned for later phases of the development.

STANSTED AIRPOR T TRACKED TRANSIT SYSTEM
South East England, UK
Essex, UK
As part of the Crossrail programme, Network Rail is installing new overhead line equipment (OLE) to serve the route. The OLE equipment is supported by gantries of various types and configurations. On some stretches the gantries date from the first electrification of UK railways in the 1940s.
The outlying terminal satellites at Stansted Airport are served by an automated Tracked Transit System (TTS), which carries passengers from the main terminal building on an elevated structure, down a descent ramp and then through a cut and cover tunnel to the satellites. In 2009, BuroHappold was appointed to undertake a Principal Inspection of the TTS structures.
BuroHappold was commissioned to carry out an urgent critical review of structural assessments conducted by others on two sections of the route. The preceding reports had concluded that significant numbers of the existing OLE gantries were inadequate to carry the upgraded OLE equipment. The condemned structures were located along the above ground sections of track between Stratford and Shenfield and Paddington and Maidenhead respectively. Using a rigorous procedure, incorporating detailed non-linear structural analysis, our team was able to demonstrate that many of the families of structures were in fact suitable for incorporation into the Crossrail scheme. This has produced significant cost and programme savings, along with sustainability benefits, since much of the existing infrastructure can be reused. Due to the urgency of the programme, several assessment teams worked in parallel to assess the structures and carry out Category 2 checks, enabling Network Rail to meet its Key Date for the Crossrail programme. Our team of specialists delivered their results in just seven weeks. Client Network Rail Design BuroHappold Engineering Image BuroHappold Engineering

The findings of the inspection highlighted a number of issues that required attention. Most notably that the supports and connections for numerous concrete track beams and steel guide beams were approaching the end of their lives. This informed BAA’s subsequent capital expenditure, which included the staged repair of guide beam and track beam supports.

CLARENCE DOCK FIXED BRIDGE
RIVER DOVE ROAD BRIDGE
Leeds, UK
Barnsley, UK
The transformation of Clarence Dock in the heart of Leeds has created a vibrant waterside community and premier tourist destination. As part of the development BuroHappold designed three bridges to connect the new development to the Royal Armouries site and British Waterways offices, across the River Aire. We carried out the engineering design from feasibility study, through concept and planning to overseeing detailed design and construction works.
As part of a design and build contract with Laing O’Rourke, BuroHappold designed the new Foulstone and Wombwell Advanced Learning Centre to replace two schools in the communities of Wombwell and Darfield, along with all associated infrastructure.
Completed in 2004, the fixed bridge has a cable stayed deck supported from two leaning frames. The design was inspired by cranes, in reference to the industrial heritage of the site. To avoid disruption to river traffic and cope with a river span too great for us to locate cranes on the river bank, we constructed a permanent central island at the start of the project, then positioned an 800 tonne crane on the island, to lift the deck into position. Sections were supported by temporary cables with the ends supported on floating pontoons and the island now supports the bridge. Two cantilevered lifting bridges of 16m and 19m respectively were also constructed, with stiffened steel plate decks springing from a pivot point attached to the quay wall.
The £55 million scheme included a new road bridge crossing the River Dove to form the primary access for 1,700 pupils and staff. The bridge has a clear span of 21.5m and is a fully integral structure with the deck comprised of precast pre-stressed beams to minimise costs. Working with Laing O’Rourke’s in-house precast production facility, BuroHappold carried out full detailed design of the bridge which also incorporates precast units to provide a high quality finish to the end abutments and parapet edge beams. The surface is designed for combined use by vehicles, pedestrians, cyclists and horses. The bridge opened in Autumn 2012.

Our first priority was to assess the structural integrity of the bridge, which is made from heavily reinforced concrete. Using impact testing and monitoring movement, we were able to establish that the structure was strong enough to cope with the combined weight of hundreds of thousands of pilgrims who visit each year. The area of bridge facing the three Jamrah pillars had proved to be especially dangerous, with large numbers rushing to start the ritual of “Stoning of the Devil� as close to noon as possible on the last
day of Hajj. We identified a path which the pilgrims could be guided along, removing sharp turns to create a more free-flowing movement of people. This approach ensured that there were no fatalities in 2005. The original bridge has now been replaced with a much improved structure.

STRATFORD CIT Y BRIDGES London, UK BuroHappold undertook detailed design of two road bridges linking Stratford Town Centre to the London 2012 Olympic Village and Westfield Shopping Centre. The bridges span railway infrastructure (both above and below ground) and the majority of construction was undertaken during normal operating times, necessitating careful planning and liaison to secure approvals and avoid disruption. The approach to one of the bridges crossed part of the Channel Tunnel Rail Link, so we undertook advanced soil-structure interaction modelling to assess the impact of construction on the tunnel. This enabled us to design a relieving structure – a platform on which the soil needed to support the bridge approach could be piled. This prevented the weight of soil from causing undue pressure on the sides of the tunnel, a vital element in our application to secure planning approval. During the 2012 Games the bridges provided the main point of entry to the Olympic Park for 80,000 spectators per day and they continue to provide a vital link to the shopping, residential and other facilities which form part of The Games’ legacy.
