The terrace of steps leading from the Albert Hall to Prince Consort Road was excavated to provide an underground set of storage and offloading facility with direct access through a tunnel to the performing arena within the Albert Hall.

The scheme comprised a contiguous bored pile wall tight to Imperial College and Albert Court on either side of the excavation and load bearing piles within the basement structure.  TGP modified the scheme to accord with John Doyle's construction philosophy to maximise use of the permanent works slabs in supporting the excavation phases by use of a partial top down technique to a maximum depth of 14m.

The excavation sequence was analysed and a new sequence of construction loads produced. Columns were set on piles at low level in cased shafts, waling beams were redesigned and detailed to cater for temporary excavation forces and slab voids spanned with temporary concrete struts for the construction phases.

Large propping loads resulted from the massive masonry buildings including the Hall itself on three sides of the site.
