Hayesfield School


Project Type:
Temporary Works

Crouch Waterfall provided temporary works designs to allow ISG Pearce to construct new school buildings at Hayesfield School in Bath. Close coordination with the site team was required to enable the temporary works and main construction programme to progress in sequence.

Due to level differences on the sloping site a 6m deep excavation was required alongside an existing school building which was to be retained. Crouch Waterfall designed a contiguous piled wall with injection ground anchors to support the existing building and allow the excavation to be carried out less than 2m away.

Steel king-post walls up to 4m high were required at various other locations on site to enable construction of the permanent works. Analysis of cross sections through the site taking into account loading from construction activities and local roads outside the site boundary were required.

Additional temporary works required included designs for piling platforms on a temporary embankment re-using clay excavated on site, designs for the site haul road with associated cut and fill quantities and design to temporarily support and underpin an existing retaining wall using mass concrete and ‘duckbill’ type ground anchors.
