University of Warwick, Faculty of Arts Buildings. Presented by Matt Gilliver, Technical Director, CCL
The University of Warwick’s Faculty of Arts building, due to complete in time for the 2021 academic year, will bring all the departments together under the same roof for the first time. The design for the new faculty includes four wings of varying height, connected by a central atrium circulation space and a double height lecture theatre with a large span.
CCL developed a solution to replace the original design of steel beams with post-tensioned (PT) concrete transfer beams and converted the RC slabs to PT. The design has reduced cost, complexity, material consumption and the number of trades involved in the project, bringing significant value and sustainability benefits to the project.

The Marshall Building is a new building for the LSE Estate. It consists of a double basement formed in reinforced concrete and a 10 storey post-tensioned superstructure above. The concrete is entirely exposed throughout, with large, impressive post tensioned transfer beams at Levels 1 and 3, known as “the tree beams”.
The building has large, open plan communal areas with maximum floor plans and minimal surface finishes.
The post-tensioned structure itself provides the centre point and main aesthetic for the building. The tree beams act as transfer beams to allow the column grids to rotate by 45 degrees between floors and accommodate the floor plans required by the client. They also create an impressive atmosphere with their grand scale, reaching 7m at their highest point, with the sloping transfer beams tapering from 3.5m deep at column locations to 1.5m mid span, creating clear typical spans of 15m.
