St Lukes

With just under 6 acres of a site, the project consists of a 3600m2 basement and transfer slab, on top of which 4 no. 4 storey RC frame blocks, and approx. 550lm earth retaining walls are located.

Surrounding these are a further 5 no. 3 storey RC frame blocks, 4 no. 2 storey RC frame blocks, and ground beams for 6 no. town houses

Works to 3 existing listed buildings include underpinning and construction of new lightwells.

There is an 11 metre difference in ground level from one end of site to the other.

• 3600m2 single sided wall waterproof basement
• 13 no. concrete frames 2, 3, and 4 storey (averaging 350m2 per floor)
• Earth retaining walls throughout
• 4 no. attenuation tanks with capacity over 700m3
• Rainwater harvesting system

• Extensive Temporary works consisting of 45lm kingpost retaining walls to support existing neighbouring walls, gardens, and trees during a 5 m deep excavation
• Waterproof concrete used throughout the entire basement carpark, also in 5 separate blocks where basements / light wells / earth retaining frames were constructed
• Removal of over 50,000m3 of inert material to accommodate basement carpark, attenuation tanks, and groundworks designs.
• Combined CETCO and PUDLO waterproofing systems to ensure two separate waterproof guarantees for underground works to houses
• Major logistical coordination so as not to disrupt three neighbouring schools during drop off and collection times.
