Waterman has been appointed by an overseas client and CORE, as Development Managers, to provide structural engineering consultancy services on the development, which was once headquarters to the Automobile Association.

This island site project has retained the high quality section of the façade up to main 5th floor cornice level and enhanced with a new striking glazed curved mansard roof above.

The scheme includes part demolition and reconstruction of the existing structure to provide a nine storey building, which will comprise 175,000ft2 of new commercial space on the upper floors and high end retail units on the ground, first and basement floors.

The contemporary roof design is supported by a central core and new perimeter stanchions with complete column-free office space and spans of up to 12m providing very efficient floor space to appropriate market standards.

A new two-storey basement was created by the installation of a secant piled wall inside the retained façade profile. Slimdek construction was determined for the B1 and ground floor slabs to maximise headroom in below ground spaces whilst minimising excavation depths.

Waterman provided a full complement of structural engineering services, including a technical assessment of the retained Portland stone façade.

On-site investigations were undertaken by our engineers to expose the internal details of the perimeter structure. This was done in parallel with an archive search in the files of the Automobile Association and the London Metropolitan Archive. The research uncovered architectural plans and photographs for the various phases of work which proved to be invaluable with respect to the scope and output of the site investigations undertaken during the pre-construction period. The details were used to inform the selected demolition contractor and the main contractor of the existing constraints during the tender and construction periods.

Waterman has designed and prepared details using Revit 3D modelling techniques to capture the integration and interfaces of both architecture and building services which will assist the future design and construction activities.
