The tender is based on 600mm piles being adopted for the whole of the project, if feasible. It is proposed that 3% of all piles will undergo working pile tests. To enable the piles, within the basement, to be installed following excavation, segmental flight auger (SFA) piles will be used with a maximum pile length of 12.1m being installed from a temporary formation level of 16.42mAOD The cut off level of the piles is 14.53mAOD & the top level of the stiff CLAY is considered to be 5.7mAOD. The total effective stress due to the structure at cut off level is 249kPa considering the water table to be at ground level. u (grey clay) =214kN/m² Ysub(grey clay) =13kN/m³ Ysub(stiff clay) =10kN/m³ 2 7 12 17 22 22 0 25 50 50 Strength Parameters verses Level ■BH01 Cu ■BH02 Cu ABH 3 Cu ABH4 Cu BH5 Cu ABH6 Cu Undrained shear strength, C, (kPa) 75 100 125 150 175 200 225 250 275 300 325 350 2 12 Level (MOD) 22 17 Made ground Soft peaty CLAY becoming firm with depth Firm grey CLAY Very stiff silty CLAY
