1.1 General
The aim is. to ca
y out the subsurface investigation to construct a new
multistory shopping complex in the city.
After having made a mutual agreement between the XServices Co., LTD.,) the
subsurface soil investigation work and laboratory testing were performed Y LTD
to determine the geotechnical properties of the subsoil for foundation design.

1.1 Objectives and Scope of Work
The scope of work for the geotechnical consultancy services of the project are
as follows:
• Soil boring, field testing and ca
ying out sufficient in-situ testing and
• Laboratory testing of obtained samples to determine the properties of the
• Determination of geotechnical parameters required for foundation analyses.
• Ca
ying out engineering analyses for foundation design.
1.3 Location of the Project Area
The soil investigation work is situated in the area of No. (4) is viewed
about 8 mile away and in the southern part of XYZ city and there exists
ailway junction station, from where two railways.

2.1 General
The investigation program included drilling boreholes and collecting soil
samples at desired intervals for subsequent observation and laboratory
The investigation program consists of soil boring and sampling at desired
intervals for subsequent observation and laboratory testing to determine the
capacity of pile foundation economically and safely.
2.2 Soil Boring
The boreholes had been made by 3 Nos. of the rotary drilling machine, namely
XY-1, XY- 1B and JOY. In the soil exploratory boring, field work was concerned
with (5) Nos. of boreholes having 50 m depth. The boring of 100 mm (4")
diameter hole was performed using a Rotary Wash Boring Rig. A metal crown bit
as a cutting tool was attached at the lower end of the drilling rods, and
circulated mud water was pumped through hollow rods into the bottom of
orehole to wash out the cuttings to ground surface. All boreholes were
terminated at the target depths of 50 meter, according to the requirement of
the client. The soil boring works ca
ied out by rotary wash boring methods
were done in accordance with
the ASTM Standard.
2.3 Standard Penetration Test
This test is ca
ied out at an interval of every 1.5 meter depth. SPT is
performed by using a split spoon ba
el sampler connected to the end of boring
ods. The sampler is driven into the soil by means of a hammer weighing 63.5
kg (140 lbs) falling freely through a height of 76.0 cm (30 inches) onto the
anvil attached to the top of the rod. A trip release mechanism &
guiding assembly are used to control the falling hammer and the driving energy
is transmitted to the soil, taking a record of the number of blows required
for each of three 15 cm (6 inches) lengths of penetration.
The resistance, N-value (blows/30 cm) is taken as the number of blows for 30
cm of the second and third penetration. The soil sample of the first 15 cm is
neglected because of being distu
ed by boring. If the blow count number 60 is
achieved before the full penetration, the test is ceased and depth recorded.
At the conclusion of the test, the sampler is taken out and soil is extracted.
The soil sample isstored in a plastic container and the depth & borehole
number labeled. Inaddition, these samples are used to describe the soil type
in the bore logs. The bore logs are attached

2.4 Soil Sampling
ed samples were taken in the first 30 meters depths at different
depths on cohesive soil samples using a thin-walled sampler with dimensions
conforming to standard sampling tubes specification (ASTM D 1587).
ed samples were collected during Standard Penetration Testing at 2.0 m
intervals in accordance with (ASTM D 1586).
The borings were drilled vertically through soil approximately 50 meters deep,
which is the target depth defined by the specification of the client.
2.5 Ground Water Level Measurement
Groundwater is one element that affects in the stability and foundation
analyses. The groundwater level was measured 24 hours after completion of the
orehole. However, the low permeability of the soil will mean that the water
level in the borehole is controlled more by drilling fluid rather than by the
ground water itself. Significant fluctuations in the location of ground water
table should be anticipated throughout the year, depending upon the amount
of precipitation, evaporation and surface runoff. The water table for each
orehole was measured using water level indicator.
The depth of water level in each borehole was monitored and recorded daily
aftercompletion of soil boring works.
2.6 Test Pit Excavation
Test pits were performed at the five locations just close to the boreholes of
50 m depth, namely BH-200, BH-201, BH-202, BH-203 & BH-204 and the pit
dimension is of 1x1m size...
