Following a single stage tender, BAM had a rapid turnaround to begin work on site in November 2019. Our knowledge was put to the test immediately when reviewing the design, in particular the cast in-situ elements such as the concrete stair cores and subsurface retaining walls. Here, we realised that by re-engineering the stair cores to a steel frame and the sub-surface retaining walls to a contiguously piled wall solution, we could reduce the buildings overall embodied carbon and prevent over 100 vehicle movements. This was of significant benefit to the project, given the University’s sustainability requirements on the scheme.
The façade of the building is constructed using precast concrete units, which came with pre-installed window units and were manufactured offsite in a factory. Our use of offsite meant that when COVID hit, we were able to maintain production. It also enabled us to have a minimal workforce on site during the installation and still achieve a high quality finish.
