We recovered disturbed samples from the bottom of each test pit and also collected construction material including clay, gravel/marram and aggregates,
We performed laboratory testing for disturbed samples including Natural Moisture Content, Particle size distribution by Sieve analysis, Atterberg limits (Liquid, Plastic and Linear Shrinkage Limits) and for undisturbed samples including Consolidation, Permeability, and Direct Shear,
We compiled the geotechnical investigations report comprising of our findings of the subsurface soil conditions, engineering analyses made on the laboratory tests and geotechnical parameters to be used in the design.
