Geotechnical Engineers have to design safe, economic and serviceable foundations and retaining walls. Engineers use design codes to guide them in this endeavour. Sadly many design codes focus too much on the prevention of collapse and not enough on the design of a serviceable, economic structure. With pressure to reduce the amount of embodied energy and carbon in civil infrastructure, geotechnical engineers should focus on development of better methods to compute differential settlement which is the major cause of structural ‘failure’. If these are available then the levels of conservatism in standard designs can be more scientifically determined. Soil-stress strain databases are presented and their use in design examples is shown. Databases are suggested as an alternative to probabilistic methods in dealing with variability of soil properties.
