Description
Experience Level: Intermediate
Task 2 – New pedestrian access route between Beckton Park DLR and London City Airport DLR
Scenario:
It is proposed to make a new pedestrian & cycle access running directly from the Asian Business Park at Beckton Park DLR to London City Airport DLR peninsular. The physical barriers that need to be overcome are the Royal Docks and the City Airport runway. The design team propose a combined 20m single span bascule bridge and viaduct to cross the docks, with a tunnel to go under the runway. The viaduct piers will be supported on marine piles whilst the bascule bridge abutments will be an caisson structure. The ground condition is a firm to soft silty clay.
You are an assistant project manager for a large design & build company who is responsible for scheming out the superstructure, groundworks and civils element of the project.
a) Describe and justify the construction methods, plant and temporary works you propose to build the bridge and viaduct. Use neat labelled sketches to show the sequence of construction operations.
b) Three different construction methods for the tunnel have been initially proposed for constructing the runway tunnels:
• Cut & cover
• Horizontal jacking
• Bored tunnelling
(i) Briefly describe each method of construction with the aid of neat labelled sketches.
(ii) Evaluate the most appropriate method for the runway tunnel clearing stating any assumptions that you have made.
