ICE’s SEE Retired Members Group has organised this site visit to be enjoyed by all grades of membership and is free to attend.

The HS2 project is currently Europe’s largest construction project. In the Thames Valley Branch area the works in progress comprise the full range of roads, piling, tunnelling, bridge and viaduct construction and a slew of associated activities which, we feel, should appeal to all members on a summer day out. The Retired Members Group committee are anticipating a further set of site visits to HS2 works zones as the project continues to spread across the region, so whilst numbers (20 persons) may be limited on this visit there will be future opportunities to see construction in the “flesh”.

This visit will see that Steelwork installation on both Wendover Dean, nearly 1 kilometre in total length, and Small Dean Viaducts is ongoing.  At Wendover Dean the 1st section of the viaduct has been launched and this visit is scheduled to witness the start of the 2nd phase, the total viaduct deck is scheduled to take nearly 12 months to complete.

At Small Dean Viaduct we will see the revised A413 road works involved in diverting the main road to permit the balance of the foundation piling and pier construction between the road and live Network Rail lines.

Steelwork for the deck is being constructed on the south side in the Launch Platform area.
