A fairly accurate assessment of the characteristics and engineering properties of the soils at a site is
essential for proper design and successful construction of any structure at the site. The field and
laboratory investigations required to obtain the necessary data for the soils for this purpose are
collectively called soil exploration. The choice of the foundation and its depth, the bearing capacity,
settlement analysis and such other important aspects depend very much upon the various engineering
properties of the foundation soils involved. Soil exploration may be needed not only for the design and
construction of new structures, but also for deciding upon remedial measures if a structure shows signs
of distress after construction. The design and construction of highway and airport pavements will also
depend upon the characteristics of the soil strata upon which they are to be aligned. Sub-soil
investigation and laboratory tests for proposed project was prepared by Oeuvre Engineering.
Objectives of Subsoil Investigation:
The objective of the exploration work was to determine the probable sub surface conditions such
as
stratification, denseness or hardness of the strata, position of ground water table etc. and to
evaluate
probable range of safe bearing capacity for the structure. To fulfill the objective, the work
carried
out is comprises of:
Drilling the boreholes up to the various depth below existing ground level in order to know the
sub
surface stratification, conducting necessary field tests and to collect disturbed and
undisturbed soil
samples for laboratory testing.
Testing soil samples in the laboratory to determine its physical and engineering properties of
the
soil samples.
Analyzing all field and laboratory data to evaluate safe bearing capacity of the soil for given
foundation sizes and necessary recommendations for foundation design and construction.
Scope of Work:
Drilling of exploratory borings up to the various depth from the existing ground surface.
Performing of Standard Penetration Test (SPT) at 5 ft. intervals up to the required depth.
Collection of disturbed (by thin walled Shelby tubes) and undisturbed sample for laboratory
test and visual classification.
Determining the ground water table in each borehole.
Determining the geotechnical properties of soil from various laboratory and field test.
Preparation of final report with all works including detailed description of soil
stratification.
