Description of the goods or services required
HS2 Main Civils Works S1 and S2 sectors - WP071_A_Pre-cast Concrete (Area West PCC elements)
The awarded supplier will be required to manufacture and supply (i.e. deliver to SCS JV's worksite/(s)) the following pre-cast concrete elements:
1. Bridge beams for the River Pinn Underbridge (RPU) and the Breakspear Road South Underbridge (BRSU).
2. Parapet units for the Harvil Road Overbridge - Chiltern Line (HROC).
3. Culvert units for the Harvil Road Underbridge (HRU).
4. Ventilation-shaft units for the Copthall Tunnel ventilation shafts.
5. Culvert units for underneath the Gatemead embankment.
6. Culvert units for the temporary bridge underneath the haul road at the Flood Compensation Area (FCA) throat.
With specific regard to items 2 and 4, it should be noted that the parapet units will be bespoke in terms of both their design (i.e. loading) and the fact that they will be to a non-standard section/(s). The same applies with respect to items 1 and 3 in terms of the bespoke design (i.e. loading), however it is likely that they will be to a standard section/(s). Items 5 and 6 are likely to be standard off-the-shelf products/units.
Although the vast majority of the design is being carried out by SCS JV's Design House Joint Venture partner, the awarded supplier will be expected to carry out reinforcement detailing and pre-stressing design. For the avoidance of doubt, SCS JV will be responsible for the installation of the above pre-cast concrete elements, thereby meaning that this package is being let on a supply-only basis.
