The Silvertown Tunnel will bring new opportunities for Ferrovial Construction over the next 5 years of delivery and provide further development for members of our team. This is the 5th tunnelling project that we have been awarded in London since 2008, following Crossrail, Northern Line Extension, Thames Tideway Tunnel and the Heathrow Baggage Transfer Tunnel.
The wind in a 3 second gust is appropriate to determine the maximum static wind load on individual members; 5 second gusts are appropriate for maximum total loads on structures whose maximum hori- zontal dimension is less than 50 m; and 15 second gusts are appropriate for the maximum total static

of the structure against a notional horizontal load equal to 1.5% of the characteristic dead weight at each floor level and vehicular impact loads (Clause 2.3.1.4). The small notional horizontal load can generally be covered by wind loads required for design
1/1/2011 · Besides the gravity loads, two specific loads, i.e seismic inertia load and wind load were considered in the structural design of this project. The current Indonesia Seismic Code (SNI 03-1726-2002), which is still based on the UBC 1997, requires the building to be designed for 500 years return period earthquake with 10% probability of exceedance in 50 years of the building’s effective life time.
In the one-way system in Figure 2a, the effect of external loads is transferred primarily in one direction, shown with an arrow. The slab- beam and-girder floor is an example of a one-way system. The gravity load acting on this system is transferred from the slab (1) to the beams (2) and then to the girders (3).
Another classic example is the Lainzer Tunnel in Vienna, an energy tunnel built by the cut-and-cover method, where the excavation is first dug in the open air and then covered by concrete slabs. In this case, the heat is exchanged with the ground using the side walls,
Perth, 18. th. June 2019. Cross Passages (CPs) Critical component in any twin tunnel transportation project: their design and construction. is often the most channeling element of the project. Typically mined tunnel with comparatively small cross section and restricted access.

Construction Overview. The project works include tunneling and construction works in main stations’ locations, controlling and operation centers, stabling and maintenance depots, casting and reinforcements works for many lines and viaducts, transfer services, providing the project with electricity and deep tunneling works of the lines.

horizontal pre-assembly and safe parallel-truss erection owing to screwed and tightly bolted connections. safe up.down access thanks to built-in ladders with ladder cage. high level of safety against wall foundation tilting and sliding thanks to optimised V-shaped strut angles.
CHAPTER 8 ΠRAILWAY STRUCTURES 387 387. Composite Design The design and use of composite steel and concrete spans for railway bridges is addressed in Section 5.1 of Chapter 15 of the AREMA Manual for Railway Engineering. This type of superstructure comprises a steel beam or girder and a concrete deck slab.
