Project Brief

The extension provides two storeys of teaching accommodation linked on both floors to the main school building at Park Spring Primary School. This provided new classrooms and associated amenity and learning facilities.

The project involved the installation of three double modular classrooms and the demolition of a single storey classroom block. This made way for the construction of a new two storey classroom block extension.


The extension features an innovative steel frame system, rather than a traditional layer of blocks behind the external façade.

The structural solution was determined as steel frame construction on mass concrete pad foundations.

Lateral stability was catered for by a combination of vertical cross flat bracing and portal bracing. The insulated structural decking construction was supported on hot rolled rafters, which were in turn held up by the steel frame. Adept was instrumental in ensuring the construction programme progressed as planned without delay despite a 6-week lead time to procure steelwork. Each construction phase was designed in a 3D Revit model, enabling Adept to work with the architect to produce drawings for the contractor. This allowed the foundations, retaining wall and ground slabs to be accurately programmed during the steelwork procurement, saving valuable time.

The Revit model provided a time efficient specification for the size of steel required for the linking corridors and provided accurate steel tonnage for contractors pricing requirements. Cut and fill modelling in Civils-3D were used and helped to take account of uneven surface levels where sandstone was cut away and re-used.

The project forms part of Adept’s education portfolio.
