City: London

The renamed East London Railway was part of Transport for London’s Five Year Investment Program, the East London Line is being extended in two phases and AECOM became involved in 2010 with the Program Cost Consultancy experts delivering cost management services for this project. As lead designer with the Balfour Beatty/Carillion Joint Venture, AECOM produced the detailed construction design for new stations, buildings, civils and structure works including architecture, landscaping, geotechnics, electrical and mechanical services.

The project extends the line in both north and south directions to connect it with existing rail services. It played a major role in transporting people to and from the 2012 London Olympic & Paralympic Games, providing a stimulus for regeneration initiatives throughout many of London’s boroughs

With a global audience of around 241 million, the BBC is the world’s largest and most renowned broadcaster. The iconic home of British radio, Broadcasting House, has long been the jewel in its crown. But ten years ago, the BBC recognised that it needed a headquarters more fit for the digital age.

AECOM was commissioned to lead the business services design, and the project has positioned us as a world leader in media design. It has involved refurbishing the original 1932 Grade II* listed Broadcasting House, and building a high-tech, 13-floor extension. Recently completed, the centre was opened by Her Majesty The Queen.

At the centre is the BBC’s news hub – a vast, day lit column-free space, and one of the world’s largest live newsrooms. A number of spaces will be open to the public including a gallery, the central piazza and a glass-walled walkway with views into the newsroom.

Broadcasting House’s advanced new tri-media facilities include one flexible and six fixed-rig TV studios, as well as 16 radio studios, countless edit rooms and transmission suites. Space-saving design has been essential.

Transforming Broadcasting House from heritage to high-definition is a demanding task. Staying on air is naturally of paramount importance: no failure of any building service system can interrupt broadcasting. The complex mechanical, electrical and control systems need to be highly resilient, as does the acoustic design.

The site’s close proximity to London Underground’s Bakerloo and Victoria tube lines and its cramped, urban location demanded innovative engineering solutions.

The redesign will save the BBC £736m over a 20-year period. This is the first broadcasting development to achieve a BREEAM rating of Excellent and our experience is already informing industry-wide guidance.

AECOM was the lead consultant and design manager for the Emirates Air Line project, the UK’s first urban cable car system. The Emirates Air Line opened in June 2012 in time for the London 2012 Olympic and Paralympic Games, providing an important new transport link to support the regeneration of East London. It has the capacity to carry 2,500 passengers per hour, improving cross-river links for both commuters and tourists. The line connects the Greenwich Peninsular and the Royal Docks.

AECOM designed the terminals on both sides of the river and conducted independent checking of the cable car towers and ship impact protection barriers. AECOM had to discharge more than 150 planning and environmental conditions to meet stakeholder requirements, including addressing the cable car’s potential impact on the flow of river traffic and its possible effect on air traffic in and out of nearby London City Airport.

The radical redevelopment of Café Royal in central London sensitively restored one of the city’s iconic landmarks, creating a contemporary 5-star luxury hotel whilst preserving the building’s rich heritage.

The refurbished hotel was previously three separate structures. The first was the original Café Royal, a famous restaurant opened in 1863 that was frequented by celebrities throughout the decades, from writers such as Oscar Wilde and HG Wells, politicians and royals including Winston Churchill and Princess Diana, to Hollywood stars like Bridget Bardot and Elizabeth Taylor. The second building at the site was a bank and the third was previously a County Fire Office.

AECOM was appointed as structural engineer and provided a complex solution that delivered the architectural vision of the project yet still protected many of the building’s original features. The structural design allowed all of the listed rooms to be retained in-situ throughout construction. It meant the original layout could be maintained, including an impressive double-storey space previously used to host 19th century boxing matches that is now the hotel’s reception area. Two Grade-I listed facades on Regent Street and Glasshouse Street were retained, from ground floor right through to roof level, throughout construction. The design balanced 21st century style with the historic 1860s and 1920s building fabric.

AECOM is the lead design consultant for the major Bank underground station capacity upgrade project, one of London’s most complex infrastructure schemes.

AECOM is delivering a wide range of multidisciplinary services, including project management; design management and assurance; civil, structural, geotechnical, mechanical and electrical engineering; tunnelling; pedestrian flow modelling; and planning and environmental services. AECOM’s designs will include a new Northern line southbound-running tunnel that will create more platform space, interchange tunnels and an additional station entrance. Tunnelling will take place under iconic landmarks such as the Bank of England and Mansion House. The station will remain operational throughout the construction.

Set in the heart of London’s financial district, Bank station is one of the largest and most complex underground railway stations in the world. Nearly 100,000 passengers use this major interchange hub every morning rush hour and this figure is set to rise. The upgrade project will deliver a much-needed capacity increase by 2021.

Crossrail was first proposed in 1974 with the London Rail study. Several intervening attempts to green light the project notwithstanding, boots finally hit the ground in 2009 and by 2018, more than 200 million passengers will travel via Crossrail each year.

Crossrail will stretch over 62 miles (100 kilometers) from Maidenhead and Heathrow Airport in the west of London to Shenfield and Abbey Wood in the east, traversing the city via a 13-mile (21-kilometer) twin bore tunnel connected to the existing underground system. The program includes eight new sub-surface stations and upgrades to 27 existing surface stations.

Knowledge and dedication

Selected as program partner in 2009, the Transcend joint venture is comprised of three world-class industry leaders: AECOM, CH2M Hill and The Nichols Group. The consortium is providing strategic management services to help Crossrail deliver the facility on time, within budget and to the highest standards.

As the lead of this venture, AECOM professionals are working as part of a wholly integrated client program management team. Both UK and international contractors dovetail on the major contract packages and at its peak, more than 14,000 staff will be working on Crossrail. AECOM experts are delivering across program and project management, program reporting, procurement, engineering management, and assurance and industry partner management services.

Going underground

Tunneling works on this US$24-billion (£14.8-billion) project are well underway beneath London and the station sites are progressing according to schedule for their anticipated opening in 2018.

At 656 feet (200 meters) long, Crossrail trains will be almost double the size of current London Underground trains and can carry 1,500 passengers. The railway will also bring an additional 1.5 million people to within 45 minutes of central London — linking London’s employment, leisure and business districts, and enabling further economic development.

Crossrail will have a huge positive impact on London for many years to come. Not only will it make the city more accessible, it will generate significant employment opportunities. AECOM coordination manager on the project, Ian Brown, explained: “Any single Crossrail station project would normally be a major city undertaking, but there are landmark station works spread across the entire city route, which makes this program special. It is wonderful to contribute with AECOM staff from around the world to a project that will benefit so many Londoners as well as those visiting and working in our great capital city.”

By the numbers

Crossrail is among the most significant infrastructure projects ever undertaken in the United Kingdom. From improving journey times across London, to easing congestion and offering better connections, Crossrail will change the way people travel around the capital.

• Crossrail is Europe’s largest construction project — work started in May 2009 and there are approximately 10,000 people working at more than 40 construction sites.
• More than 35 million work hours have been completed on the Crossrail project so far.
• Crossrail will transform rail transport in London, increasing capacity by 10 percent, supporting regeneration and cutting journey times across the city.
• The Crossrail route will run over 62 miles (100 kilometers) from Maidenhead and Heathrow in the west, through new tunnels under central London to Shenfield and Abbey Wood in the east.
• There will be 38 Crossrail stations including nine new stations at Paddington, Bond Street, Tottenham Court Road, Farringdon, Liverpool Street, Whitechapel, Canary Wharf, Custom House and Woolwich.
• Crossrail will bring an extra 1.5 million people to within 45 minutes of central London and will link London’s key employment, leisure and business districts — Heathrow, West End, the City, Docklands — enabling further economic development.

Tunneling information

• A total of eight tunneling machines will be used on Crossrail. Each tunneling machine is a 1,100-ton (1,000-metric ton), 492-foot (150-meter) long underground factory with 20-person ‘tunnel gangs’ working in shifts.
• At peak times, the tunneling machines aim for approximately 328 feet (100 meters) of tunneling progress per week — as the tunneling machines move forward, precast concrete segments are built in rings behind — 250,000 tunnel segments will be used to line the 26 miles (42 kilometers) of tunnels.
• 4.9 million tons (4.5 million metric tons) of excavated material from the tunnels will be shipped to Wallasea Island in Essex where it will be used to create a new 1,500-acre (607-hectare) nature reserve.

Jobs and supply chain

Over the course of the project, Crossrail expects there to be at least 75,000 opportunities for businesses, generating enough work to support the equivalent of 55,000 full-time jobs. However, it’s not just London and the South East that will benefit from Crossrail. Firms around the country and of all sizes are winning business:

• More than a third are based in London
• 62 percent are outside London
• 58 percent are small- and medium-sized businesses

Skills and legacy

• Crossrail already has more than 260 apprentices working on the project. At least 400 apprentices will be created by Crossrail.
• The Tunnelling and Underground Construction Academy (TUCA) is a purpose-built training facility that supports the key skills required to work in tunnel excavation, underground construction and infrastructure.
• By building and establishing TUCA, Crossrail is contributing to the development of new qualifications as well as health and safety standards across the industry.
• Crossrail is working with industry, professional entities and other organizations with a requirement for skilled underground workers,to ensure the facilities and training at TUCA are aligned with the needs of the industry.
• Crossrail has a target of providing 350 work placement opportunities across the project.

Sustainability

• Project contractors are exceeding recycling targets with more than 92 percent of demolition and construction waste beneficially reused.
• More than 98 percent of excavated material is recycled with the vast majority being used to create a nature reserve at Wallasea Island in Essex.
• Crossrail rolling stock procurement includes requirements relating to regenerative braking, energy consumption and weight limits.
• All lorries delivering to Crossrail sites are required to carry additional safety features and regular drivers must undergo additional road safety training.

General benefits

Increased capacity:

• Crossrail will increase London’s rail capacity by 10 percent. This will reduce congestion and allow for more comfortable journey conditions.
• Congestion at many stations will be reduced, even for those that are not on the Crossrail route — such as Oxford Circus.

Improved connectivity:

• Crossrail will make it easier for businesses to move about London, to meet clients and negotiate with suppliers.
• Moreover, Crossrail will make accessing major international gateways like London Heathrow more accessible. Most commentators see the UK’s future economic prospects being linked closely to an increase in international trade and the ability to export more — particularly to emerging economies.
• The journey time from London Heathrow to the City of London (Liverpool Street) will fall from 55 to 32 minutes.

Timeline and future milestones

2014:

• In early 2014, Crossrail’s final tunneling machine will be launched from Pudding Mill Lane in east London.
• The contract for Crossrail’s new high-capacity rolling stock will be awarded in 2014.
• By the end of 2014, the vast majority of Crossrail’s 26 miles (42 kilometers) of tunneling will be completed and the major civil engineering works will be completed.
• In late 2014, Transport for London is due to confirm who has been awarded the Crossrail operating concession from 2015.

2015-2017:

• Major fit-out of stations and tunnels continues as does the major upgrade of the existing rail network for Crossrail services by Network Rail.

2017:

• The first new Crossrail rolling stock will start to replace existing suburban trains between Liverpool Street and Shenfield.

2018:

• In late 2018, the first Crossrail services will start through the central London tunneled section.

2019:

In late 2019, the full Crossrail service will be operating from Heathrow and Maidenhead to Abbey Wood and Shenfield.

Brent Cross Cricklewood is one of the largest mixed use regeneration projects in the UK. The £4.5bn scheme includes the transformation of Brent Cross shopping centre, improved highway and public transport infrastructure and 7,500 new homes. Transport improvement plans include the comprehensive redesign of major road junctions, a new railway station, bus station and improved bus services, as well as enhanced pedestrian and cycle networks. The scheme is expected to support up to 27,000 full time jobs and will be a huge economic boost for the area.

AECOM has been involved with the project since 2005, delivering a range of services to support the Brent Cross Cricklewood Development Partners with its plans for the redevelopment. Services include the delivery of transport planning and infrastructure engineering advice to support the scheme’s planning application, which was approved by Barnet Council and the Mayor of London in 2010. Ongoing services include the preparation of extensive transport modelling, as well as detailed designs for new infrastructure at the 250-acre site.

The first phase of the scheme includes new pedestrian bridges, the new bus station, improvements to the River Brent, the key road junction works and around 1,250 new homes. Construction of this phase is expected to start in 2015, and there are a further six phases of development planned over a 20-year period.

AECOM provided civil and structural engineering design for this redevelopment in Romford town centre, northeast London. Barratt East London entered into a joint venture with The Mall Corporation for the redevelopment of this site in Romford town centre. AECOM’s services increased the speed of construction throughout this project.

At ground floor level is a new ASDA superstore and above this a multi-story residential development, making it one of the first schemes in the country where high-rise residential accommodation has been built over a major superstore. The residential development consists of 149 private and 80 social housing apartments split between three blocks. The tallest of these buildings is 12 stories high and is located directly above the supermarket.
