calfordseaden was appointed to provide a range of services utilising BIM for this primary school project. This project was our first in-house fully BIM coordinated school project. The scheme provides a two form of entry in the primary phase and is part of Lewisham’s strategy to accommodate ever growing pupil numbers.

The initial planning approval had already been granted for an existing 2D design. We worked collaboratively with the contractor and project stakeholders to produce a 3D model that incorporated a number of improvements over the original design, whilst remaining within the restrictions imposed. The model was shown to clients during meetings which they found extremely beneficial in providing a greater understanding of the buildings appearance and suitability. The structural, M&E and architectural models were used to enable the production of robust tender information.

The building heights had already been set by the planning approved drawings; the stepped building and low heights gave us very limited ceiling service zones, therefore BIM helped us fully understand the implications and allowed us to creatively overcome the problems before getting to site. BIM also helped our team and client identify constraints, opportunities and solutions to be explored in the design.

An internal ‘heart space’ forms the hub of the school with its split levels in order to address the sites topography; the full height nature of the atrium provides many challenges with regards to servicing. With the use of BIM however, we were able to address these issues by introducing service runs through the split levels, the atrium zone and the adjoining hall.

BIM also helped us to identify any clashes between the structure, the fabric and services of the new build which we were able to resolve before construction began. The school uses our data rich model as live O&M manuals.
