Alperton Community School, Wembley

Project Value: £17m

Contractor: Kier Construction – Southern, Maple Cross

Architect: Nicholas Hare Architects, London

 

Alperton Community School is a specialist coeducational secondary school and sixth form with academy status and is committed to helping each student to be the very best they can be within a supportive, caring and highly inclusive community.

The school was selected for redevelopment through the Governments £4.4 billion Priority School Building Programme (PSBP), a project led by the Education Funding Agency (EFA).

The project aimed to provide students with hi-tech learning facilities and teaching accommodation. Comprising of 83 classrooms and a new sports hall with activity and dance studios that can be used by the local community.

The initial stair balustrade design included vertical bar railings which raised concerns with Kier, due to a need for onsite fabrication and painting which incurred hidden costs to budget and programme. Kier faced difficulties with installation times, compliance, and achieving a suitably finished product.

To combat the issues Delta Balustrades proposed the use of the Orbis system with glass infill to provide better value, quicker installation, a consistent factory finish and high performance in meeting loading requirements.

A 1200mm high solid wall around the voids was proposed and, for safety reasons, the client requested an additional glass balustrade of 500mm high be added.  Kier required input from the balustrade company to assist with the design prior to the structure of the wall being confirmed.

To facilitate this requirement Delta Balustrades provided a design detail for the void balustrade fixing to assist Kier in confirming the steelwork design, prior to the void becoming a confirmed instruction from their client. A sequencing plan for the fixings and boarding was discussed and agreed with the site team.

Early engagement, regarding the void balustrade detail and sequencing, ensured fixing points could be set out before the boarding. This eliminated fixing through finished boarding and glass installation could follow much later, following full completion of the solid balustrade and timber capping.

Choosing the correct balustrade system enabled the manufacture and finish offsite, allowing Kier to overcome the challenges of onsite fabrication and painting.  Installing a finished product also had a positive impact on installation times, overall programme and sequencing.
