For this project, Cadman constructed a single storey, split level ground floor student area, built on a steep slope adjacent to the Roman wall in Colchester.
The site is of particular archaeological interest, and so a shallow raft foundation was chosen for the substructure design. We used ground consolidation techniques were to stabilise the soils at this shallow depth, whilst retaining undisturbed archaelogical artefacts. A castellated steel frame was used as the primary structure with a single ply membrane roof covering, supported on timber joists. Walls were a mixture of rendered blockwork and curtain walling. Internally, the castellated steel frame was exposed with an acoustic plasterboard ceiling at high level. Mechanical service ducts (spiral) ran between the castellations, creating a modern industrial feel. A green roof completed the highest level of the building, which when viewed from the main roads, around the site is barely visible.
