A cost-effective and sustainable underground strategy can be found for moving people, freight and all the vital power and water utilities needed to keep modern and developing societies functioning.
Arup's approach to tunnel projects embraces all that is best in truly multidisciplinary and joined-up design. A holistic approach, based on a strong core team of experienced tunnellers, drawing on the capabilities of a wide array of allied disciplines, allows Arup to provide 'tunnelling plus' advice.
From life safety and tunnel ventilation to materials technology and lifecycle cost analysis, Arup's tunnel projects extend from inception to operation and beyond. This total design approach, using committed specialists working closely together, has produced exciting and innovative answers to some of the world's largest and most complex tunnel projects. These challenges are welcome, giving the firm the opportunity to implement integrated projects of real value to clients.
From community to commuting
Arup led the contractor's engineering design for the design and construct contract for a vital intake tunnel at Lake Mead, Nevada that will safeguard water quality and supply for the city of Las Vegas. Not only does the tunnel pass through extremely challenging ground and groundwater conditions, it also requires the expertise of Arup's materials and hydraulics specialists to design the tunnel's deep water lake intake. The design team's cost-effective work significantly reduced construction time and risk, a vital consideration for the contractor client and project promoter.
The Elizabeth line will be a new railway for London and the South East connecting Reading and Heathrow to the west of the capital, to Shenfield and Abbey Wood in the east and directly linking Heathrow Airport, the West End, the City of London, and Canary Wharf. We designed the 42km of bored tunnels that run under central London navigating them through the congested subterranean world. Using our experience from HS1 we helped develop the tunnelling strategy, reducing the number of tunnel boring machines required.
Sustainability in a changing world
The rapid growth of city populations has placed increasing pressure on infrastructure systems. There is a growing recognition that going underground is the right thing to do. From subway systems that take cars off the street to aqueduct and power tunnels that provide the necessities of life, tunnels and underground space offer sustainable and cost-effective alternatives. Arup has been at the forefront of the development of larger and more complex underground spaces in response to the demand for more cost-effective uses for them.
