Structural design for luxury apartment blocks Left Bank

A two-stage tender project to build two towers, one 22 storeys and the other 31, but with further capacity to extend with 2 and 4 storeys of penthouses respectively.

Located at the top end of Broad St behind an existing listed building the towers are being constructed on a busy compact city site and are intended to provide apartments, with retail on the ground floor.

Unique Factors:

The RC frames are being slip cored with the floor plates all post tension prestressed concrete supported offblade columns. The pile foundations extend into the Sandstone bedrock which is generally solid but there were variances noted that required a further detailed site investigation to understand the nature of identified water features found.

As part of our commission we have undertaken the section 278 design and management and have helped plan the access throughout the construction period and design the project temporary works for the contractor.
