Sq. Root of Time Fitting Plot
Determination of Coefficient of Consolidation (Cv) as suggested by Taylor is accomplished through this method by plotting Dial gauge Reading for compression of the specimen, as ordinate for any pressure increment in the consolidation test, with Sq. root of time as abscissa. Using either manual or guided extrapolation of the curve straight part, one can easily determine Cv with extreme accuracy and in a very short time. A maximum of 2 plots in a report sheet is possible to be drawn.

Settlement Calculation
Settlement analysis of a foundation resting on a firm layer is to be computed from this module. I.S. code method along with other standard conventional methods have been adopted for the purpose of computation, as per the choice of user. 2:1 method or Bousinesq method can be followed as per selection of user to find out the Stress distribution. Detailed manual calculation in a well formatted page layout will be available at the end for the purpose of viewing, printing etc. These calculations are transferable to word processor.

Bearing Capacity Calculation
Computation of bearing capacity is a very tedious job. One can have this lengthy process, of finding bearing capacity as per IS code, reduced to a few simple mouse clicks. All the considerations are being taken up automatically by the software. Even, for same type of soil, allowable bearing capacity values can be computed for a large nos. of footing size through RANGE option. Very nicely formatted sample manual calculation sheets are automatically generated which may be saved, preview for printing and can be printed also from the software. Forth coming version will include a detail comparative statement for bearing capacity computed as per the guide lines thrown by different renowned geotechnical experts.

Under-reamed Piles
Of the various methods of foundation design in expansive soils, the pile and beam construction with the pile going down to and anchored in the zone of inappreciable movement is a very popular method.
