Tunnel jacking pits, Boston Central
ArteryThe design and construction of cut-and-cover
structures embraces a full range of foundation engin-eering
techniques we've carried out around the world. Our experience
involves extensive work in difficult ground conditions including
very soft alluvial deposits and over consolidated swelling
clays.
In addition to metros, underground railways and roads, Mott
MacDonald has designed numerous special structures to stringent
defence standards. Measures to minimise traffic disruption during
construction have been successfully incorporated into the design of
numerous projects, especially in urban locations.
An understanding of soil/structure interaction is a major factor in
achieving successful foundation engineering solutions. Our team
have the skills and experience necessary for cut-and-cover
construction.
Notable projects in the UK include the Channel Tunnel,
cut-and-cover railway tunnels at Castle Hill, Holywell and the
Terminal Loop at Folkestone, where significant programme and budget
savings were made by eliminating movement joints and external
membranes while still providing a watertight structure.
Some more of our key tunnel projects include:
- Limehouse Link, UK
- Boston Central Artery, USA
- Heathrow Express, UK
- Putrajaya Light Rail, Malaysia
