This document summarizes a soil investigation report for a construction project in Karachi, Pakistan. It lists the group members conducting the investigation and the tests performed, which include standard penetration testing, grain size analysis, Atterberg limits testing, unconfined compression testing, point load testing, direct shear testing, and specific gravity testing. The standard penetration testing involved drilling 4 boreholes to 50m depth using rotary drilling and performing tests every 1.5m. The other tests aimed to determine properties of the soil like grain size distribution, water content, strength, and shear strength.

REPORT REFERENCE:
A program of Subsoil Investigation was undertaken to determine subsoil
conditions for Tower “H” at Creek View & Terraces, Phase VIII,DHA,Karachi.
Consolidated Engineering Services (Pvt) Ltd, Karachi carried out the program of
the soil investigation.
LIST OF TESTS PERFORMED:
1. Standard Penetration Test (SPT)
2. Grain Size Analysis
3. Atterberg Limits
4. Unconfined compression and Point Load Test
5. Direct Shear Test and Specific Gravity

2. STANDARD PENETRATION TEST:
A total of 4 boreholes were drilledup to 50 m depth. Rotary drilling method was
used to advance the borehole to the required depth. SPT was performed at 1.5 m
interval by using Donut hammer.

4. GRAIN SIZE ANALYSIS:
This test is performed to determine the percentage of different grain sizes
containedwithin a soil. Sieve analysisis performed to determine the distribution
of the coarser, larger-sized particles, and the hydrometer method is used to
determine the distributionof the finer particles.
ATTERBERG LIMITS:
Atterberg limits is a basic measure of the critical water content of fine-grained
soils. These tests include shrinkage limit, plastic limit, and liquidlimit. Depending
on the water content of a soil, it may appearin four states: solid, semi-solid,
plastic and liquid.

5. UNCONFINED COMPRESSION & POINT LOAD TEST:
The primary purpose of the Unconfined Compression Test is to quicklydetermine
a measure of the unconfinedcompressive strength of rocks or fine-grained soils
that possess sufficient cohesion to permit testing in the unconfinedstate.

6. DIRECT SHEAR TEST & SPECIFIC GRAVITY:
A direct shear test is a laboratoryor field test used to measure the shearstrength
properties of soil such as cohesion and Angle of internalfriction.
