1. MACKINTOSH PROBE
The Mackintosh Probe Test is a simple and economic testing method to gather preliminary data on sub surface conditions. Such data maybe adequate for the designs of foundations for lightly loaded structures as this provides a very economic method of determining the thickness of soft deposits such as peat.

2. HAND AUGER
Used in soft to stiff cohesive soils or sandy soils above water table. Maximum depth is about 5m. Is particularly valuable in connection with ground-water determination

3. STANDARD PENETRATION TEST
Suitable for almost all soil types except very soft clay & coarse gravel. Disturb samples (35 mm diameter) are procured from the test for field. Identification/description of soil types and subsequent lab classification and index properties test. Is usually carried out at a change of strata or 1.5 m interval .
4. VANE SHEAR TEST
Very suitable for very soft to stiff clay to obtain Undrained Shear Strength of these soils. A four –blade is drive into the soil at the end of a rod and the vane then rotated at a constant rate between 6 and 12 deg./min until the cylinder of soil contained by the blades shear. The maximum torque required for this is recorded.

| VANE SHEAR TEST |
I'm new in the field of engineering. I got confused in how to evaluate the SI report given to me so that it can be use in my slope stability analysis.. the report does not have unit weight of soil, cohesion and angle of friction which I need to have in order to proceed with the analysis. What I find in the report contains mackintosh probe result, spt result and some limited laboratory tests namely particle distribution and atterberg limit. Is there any reason the information I get from the mackintosh and spt could be translated into unit weight, cohesion and angle of friction, or probably the contractor himself didn't give me enough informations..
