Basement Excavation: Imperial College London


Here are some recent photos taken of our secant basement excavation complete at Imperial College London for GRAHAM Building, revealing our 600mm diameter hard hard secant piled retaining wall. 

Sections of the wall are temporarily propped above capping beam level, whereas other areas are acting in cantilever. All 600mm diameter load bearing piles along with temporary tower crane piles up to 25m in length have been cropped in preparation for basement construction.
