The site is particularly narrow at this eastern end, so the contractors have to work particularly methodically, they start by installing sheet piling, reduce the ground levels to expose existing piles, crop the piles to size, install rebar frame and infill with concrete to create base level, then move westward along the frontage of Royal Mint Street. The works are carried out very close to the new DLR encapsulation works, so great care is required not to touch the new structure.
