ABSTRACT
2.1.2 Facades and RER roof The facades are completely independent from the TGV roof structure. The facade consists of pin based masts stabilised by struts which prop them back to the concrete on the east side and to the adjacent RER roof trusses on the west side. The masts and the trusses are spaced at 4.8m and the mast height varies from 0 to 15m above the RER roof level.
