Dussindale Primary School, Norwich

Dussindale Primary School, Thorpe St Andrew, Norwich, Norfolk

Dussindale Primary School, Norwich was the first new school to be constructed in Norfolk for over 30 years. It is a two storey structure incorporating a gym, external classroom areas, green sedum roofs etc.

One of the more difficult structural design elements was the slim overhangs at both first and second floor levels. Full three dimensional CAD design was necessary to ensure the steel sections were as shallow as possible so that the slender line envisaged by the architect was realised.

The design and detailing of the circular external classroom areas was not straightforward. As a direct result of the tendency to lateral instability we utilised specialist precast concrete sitting areas as Kentledge to ensure full stability. The construction of these elements was complicated and we liaised directly with all parties involved in the construction phase to ensure compliance. This involved us sourcing the specialist subcontractor and formulating method statements.

A further complication was the designing of the attenuated water system. As the site was undeveloped, discharge off site had to be maintained at Greenfield runoff rates. This required extensive research and significant liaison with the Environment Agency in order to design the aquacell tank and the associated hydro brake.
