 Thank you mr.charles , well, I agree with answer of my dear brother eng. Hatem . So the Design philosophy  that the design loads with adequate geotechnical and structural capacityand with tolerable settlements in conformance to the performance requirement of the structure. The following shall be satisfied

• Ensure that there is an adequate margin of safety against the possibility of pile failure under 

working loads.

• Limits settlement of the foundations and the differential settlement between the foundations 

(abutment/piers) to values that are consistent with performance requirements of the 

superstructure.

• The overriding influence of site geology, construction methodology and quality control adopted

on rock mass properties and overall design shall be recognised in the design of CIP piles.

• Limit the mobilisation of peak side resistance when there is uncertainty as to the ultimate 

capacity in end bearing in the design of CIP piles.

• In addition to these above, for piles socketed into rock, an iterative design methodology 

reviewed on the basis of socket inspections to validate the geotechnical model and the design 

assumptions needs to be ensured. In particular, the load transfer mechanism between the 

shaft and the base adopted in design needs to be justified on the basis of the socket 

inspections.

• Site inspection and verification of constructed sockets by an RPEQ qualified Geotechnical 

Engineer or an Engineering Geologist with over10 years’ experience in similar civil 

engineering construction works is mandatory. Sign off (certification) shall be by a RPEQ 

 Geotechnical Engineer.

70 tons lorry is the design live load with case of loading

so you can use it as actual test

CMIIW ,the safety factor and durability built up first from stability, dont it?
