Geotechnical investigation report, Valenzuela City, Philippines

Summary

This report presents the geotechnical investigation conducted by Geoscience Technologies, Inc. for a proposed residential complex in Brgy. Coloong #1, Valenzuela City, Philippines. It outlines field and laboratory methods used for site characterisation, including borehole drilling, standard penetration tests, and soil sampling. The study evaluates the physical and engineering properties of subsurface conditions to support the design and construction of appropriate foundations.

The findings describe subsurface layers consisting of soft silts, clays, and dense soils at greater depths, with implications for structural foundation design. The report includes analysis of soil behaviour, pile capacity, and seismic considerations, noting a high liquefaction potential in the area and the need for careful engineering decisions during construction.

It concludes with recommendations for foundation systems and emphasises the importance of continuous observation of subsoil conditions during project implementation.
