© Int. J. of GEOMATE. The study focuses on the analysis of the pile capacity and pile length for various cities of Metro Manila. Standard Penetration Test (SPT) N-values from soil reports were used to compute for the geotechnical parameters such as the undrained shear strength and the angle of internal friction which were directly applied in the computation of the allowable pile capacity. The estimation of the pile length, on the other hand, was done by means of determining the depth of the refusal or rock layer. The proposed minimum pile length and the allowable pile capacity values for each city are plotted to establish a contour map. By means of the collected borehole data, the allowable pile capacity was computed, which was shown in the reference as a series of contour maps. The contour maps were provided to show an overview of the soil's pile capacity at various locations in Metro Manila, Philippines. The contour maps presented vary by means of the design of pile, the size of the pile and the proposed pile length for a specific city or municipality and for the entire Metro Manila. A Geographic Information System (GIS) database was made so as to have storage for the collected borehole data and their locations. The database can be updated for the availability of new data.
