4. Description: About the Opportunity:
The Awarding Authority is the new High-Speed Rail Network running between specified location.
Skanska Construction UK Ltd, Costain Ltd, STRABAG AG (SCS) have been awarded the two Main Works Civils Contracts (MWCC) – S1 and S2 tunnels (estimated price circa 2 billion).
S1 includes two 9 km twin bored tunnels between the new HS2 stations, Euston and Old Oak Common.
S2 continues from Old Oak Common with 15 km of twin bored tunnels to West Ruislip where there is approximately 5 km of open route before transitioning into C1 lot (managed by Others).
SCS’s scope will include the full design of all Main Civil Works for the Lots S1 and S2 of HS2. Whilst the works consists mostly of civil engineering elements, there is also a substantial MEP element associated with shafts and headhouses.
Three of the tunnels on the HS2 route require shafts. These are the Euston, Northolt and Chiltern tunnels.
the Euston tunnel (7.4 km / 4.6miles long) will have shafts at Adelaide Road, Alexandra Place and Salusbury Road;
the Northolt tunnel (13.5km / 8.4miles long) will have shafts at West Gate, Greenpark Way, Mandeville Road and South Ruislip; and
the Chiltern tunnel (15.9km / 9.9miles long) will have shafts at Chalfont St Peter, Chalfont St Giles, Amersham, Little Missenden and Chesham Road.
Tunnel ends will be constructed with ‘Porous Portals’ which have openings to the outside air.
All interconnecting openings to the tunnel include for Mechanical and Electrical systems.
The Project is split down into 3 areas, Area East (Euston), Area Central (Old Oak Common) and Area West (West Ruislip) along the route of the project there are 11 assets. An Asset is either classed as a shaft and head house or a portal and head house.
The SCS JV procurement strategy is to create a Framework of Airside/HVAC suppliers to work as an integrated team across the 3 areas to undertaken works within each allocated asset.
Suppliers will contribute to the production of coordinated drawings, produce single service drawings, complete technical submissions develop specification into a compliant detailed design specification, fabricate materials, supply plant and equipment, install, preserve, test and commission and set to work HVAC and Life System systems.
Suppliers will work together to explore and implement measures that safeguard and accelerate the project programme and SCS will be looking for expertise on offsite preassembly and prefabrication.
The HVAC/Airside suppliers’ scope of works shall include, but not be limited to, preparation of the design, supply, recalculation and checks of system resistances, delivery of the materials and equipment to site, installation, integration, testing and commissioning and handover in complete working order of the Fire Systems.
