Cavendish House, Norwich
Pentaco Construction Ltd were selected under a two-stage tendering process to carry out the £2.5m refurbishment of near derelict Cavendish House for the Norwich University of the Arts. The first stage tender process involved the submission of preliminary costings and contractors’ proposals for the project, followed by an interview process after which Pentaco Construction Ltd, as the successful preferred contractor, worked closely with Real Consulting to establish a contract sum. The works involved retaining the existing 4 storey brick façade of the building, which stands on a busy Norwich city centre street, whilst completely demolishing and reconstructing the internal structural floors, using an easi-joist solution and structural walls of the building. The temporary support system was a very complex structure and required meticulous design, planning and co-ordination as part of the contractor’s design portions for the contract.
The works also included designing and fitting of structural frameless glazing to the ground floor gallery area and rain screen cladding to external, high level elevations. Having reconstructed the internal structures and roof of Cavendish House and replacing all aluminium windows and stone window cills, the works then moved into the fit-out phase of the contract, which included all floor, wall and ceiling finishes, new staircases, oak framed joinery, doors, partitions and a full toilets area fit out. The building boasts state of the art mechanical and electrical installations with a BMS system. The contract was placed under a JCT Standard Building Contract Without Quantities 2011 With Contractor’s Design.
