Restricted invitation to tender, deadline 16th May, 2001, for design and target cost construction of $150 million, 2 km-long Stonehenge bypass tunnel in chalk for UK Highways Agency, Birmingham, fax +44 (0)1216 788299. World heritage site, for which TBM would be the natural choice. Visit www.mottmac.com and www.highways.gov.uk 18/01. Prequalification list for tunnel to divert A303 road around Stonehenge World Heritage site includes Costain-Balfour Beatty, Skanska, Mowlem-Miller, Sir Alfred MacAlpine-Amec, and Sir Robert MacAlpine-Bouyges. This is notionally a cut and cover tunnel with bored option. However, cut and cover is not a realistic proposition in an area of such archaeological importance, so the underground option is likely to be chosen. Visit www.highways.gov.uk 38/01.A jv between Balfour Beatty and Costain has been awarded an improvement scheme contract for the A303 road close to Stonehenge by the Highways Agency. The project includes a bypass for the village of Winterbourne Stoke and a 2 km tunnel for the A303. The jv will be supported by designers Halcrow and Gifford. Construction work to start in 2005, subject to Public Inquiry. Visit www.highways.gov.uk 14/02.The government has shelved plans to build a 2.1 km tunnel by burying the A303 in the surroundings of Stonehenge because the tunnel's estimated cost has ballooned from GBP284 million two years ago to GBP470 million. The new estimate would have made the Stonehenge tunnel one of the most expensive stretches of road ever planned, exceeding the 1.6 km Limehouse link tunnel from the City to Canary Wharf in east London, which cost GBP450 million in the early 1990s. The increase in the cost was due to two main factors: very large quantities of soft, weak chalk and a high water table, with the ground water potentially rising to the surface at times of heavy rainfall. These factors would significantly complicate the tunnelling process and extend the overall construction period of the scheme. Construction was due to have started this spring and the tunnel would have been completed by 2009. Click uk/34. 30/05.

Highways England has been awarded to an Atkins/Arup joint venture. It is a package of work with an estimated value of EUR23.04 million to design options for A303 between Amesbury and Berwick Down to take to public consultation and ultimately to find a preferred route announcement. The scheme includes a tunnel near Stonehenge and a bypass for the village of Winterbourne Stoke. Subject to statutory procedures, the proposed scheme is on target for construction work to start by April 2020.

The design team, appointed under Highways England’s Collaborative Delivery Framework (CDF), will provide technical services including highway and tunnel design, environmental and geotechnical engineering, acoustics and prepare a public consultation on options in readiness for a preferred route announcement.

Highways England has shortlisted the following three international groups to build the EUR1.85 bn (GBP1.7bn) Stonehenge tunnel:  BM JV (Bouygues Travaux Publics SAS and J Murphy & Sons Ltd), HD JV (Hochtief Infrastructure GmbH and Dragados SA) and MORE JV (FCC Construccion SA -42.5%, Salini Impregilo SPA-42,5% and BeMo Tunnelling UK Ltd -15%). The three groups in the next 6 months will have a competitive dialogue with Highways England. They  have to submit their final tenders by October. The winner will be announced in 2021.

At the beginning of March in the 2020 budget document from the UK government confirmed the funding of the new, high-quality dual carriageway and of the two-mile tunnel in the South West to speed up journeys on the A303 removing traffic from the iconic setting of Stonehenge.

The government is transforming regional connections through the largest ever investment in England’s motorways and major A roads. The second Road Investment Strategy (RIS2) will spend over £27 billion between 2020 and 2025. The project is included in the RIS2. For further information please use this link . 13/20.

National Highways (UK) selected the More Joint Venture composed of Webuild (42,5%), FCC Construccion (42.5%) and BeMo Tunnelling (15%) as its Preferred Bidder for the GBP1.25 billion (EUR1.48 billion) contract for the tunnel and main construction work for the A303 Amesbury to Berwick Down scheme past Stonehenge. The A303 Stonehenge - Main Works Contract covers the construction of the proposed 2 miles (3.3 km) tunnel’s civil, structural, mechanical, electrical and technology components along with the approach 8 miles (approximately 13 km) of free-flowing, high-quality dual carriageway roads, a new bypass to the north of the village of Winterbourne Stoke and junctions with the A345 and A360 either side of the World Heritage Site. Estimated duration construction works 5 years.    

The tunnel alignment will be underneath the World Heritage Site, closely following the existing A303 route, but a further 50 metres away from the Stonehenge monument, avoiding important archaeological sites, and avoiding intrusion on the view of the setting sun from the stones during the winter solstice .  

The contract will only become live once the Secretary of State for Transport has concluded the current process of relooking at the planning application for scheme, following the quashing of the decision to grant the Development Consent Order last year.   

The More Joint Venture will be supported with a design partnership made up of Atkins, Jacobs and Sener.

The GBP70 million project is the first phase of a GBP200 million scheme, in which 50 huge electricity pylons will be removed. The removal of pylons will free up more than 40 hectares of land for development of the Olympic Park for the 2012 Games in London. Builders will construct 12 km of tunnels to replace power lines which run across the Lower Lea Valley. Two power tunnels will be constructed 20 m underground, one at 2.5 m for EDF Energy and the other 4 m in diameter for National Grid. The larger is on the same scale as a London metro tunnel and will have its own monorail running down the middle for inspection and servicing.

United Kingdom, Falkirk - uk/26

Canal

British Waterways has awarded the contract to construct a $2.4 million, 150 m-long, 7m-diameter tunnel to connect the disused Forth & Clyde and Union canals near Falkirk to regenerate the canal corridor across the Scottish Lowlands, from Glasgow through to Grangemouth and Edinburgh. Main contractors for the scheme are a jv of Morrison Construction Ltd and Bachy-Soletanche. The tunnelling work is sub-contracted on a design and construct basis to Spray Concrete Ltd in association with Joseph Gallagher Ltd whose tunnel designer is High-Point Rendel. Excavation in boulder clay overlying coal measures strata will be carried out using a Schaeff ITC 112 E3 backhoe/loader and the tunnel will be lined with sprayed concrete. A novel feature of the tunnel will be that it will pass above abandoned claystone workings and will be required to withstand possible future collapse. To achieve this the tunnel, and canal base, will be specially strengthened to bridge an anticipated maximum void created by a roof failure in the room and pillar workings some 20m below the tunnel invert. The tunnel also passes below the remains of the Antonine Wall, a 60 km-long Roman earthworks structure dating from the second century AD and constructed some 160 km north of the more famous Hadrian's wall. More from hprendel@btinternet.com March 2000.  Good progress reported on 147m-long, 7m-diameter Roughcastle tunnel, part of the new Millennium Link Canal connecting the Forth & Clyde and Union canals. Classical NATM method with single side drifts in the boulder clay of the upper half excavated using a Schaeff ITC 112 E3 backhoe/loader with a rock breaker attachment. Holethrough of first side drift expected next week. Bench to be excavated in sandstones and mudstones using a road planer. This method used successfully on the Channel Tunnel Rail Link North Downs tunnel in chalk (see uk/20). August 2000.
