Our tallest slip form Core

Morrisroe, working with BAM Construction Ltd were appointed to construct the 119m lift and stair core, rising from level B3 of the four-storey basement in the former NatWest Building car park. We also completed the substructure including the basement extension on Newhall Street. The large RC core comprising 3,500m3 of concrete was constructed using slipform, with the subsequent composite floors cast onto the steel frame.

Technical and logistical challenges

The project presented numerous technical and logistical challenges; including utilizing existing basement structures and features as part of the foundation, and pumping C60 concrete to the top of a 26 storey slipformed core, and locating a Tower Crane on top of the core to provide a second hook for the steel frame erection.

Technical and Design

Morrisroe & Kingscote Design supported the client’s design team by modelling the core in its temporary condition, as well providing technical and logistical solutions for the B1 extension construction and protection of neighbouring buildings during construction of the composite floors.
