2. INTRODUCTION OF SITE INVESTIGATION
Site Investigation is the geotechnical investigations
performed by geotechnical engineers or engineering
geologists to obtain information on the physical
properties of soil and rock around a site to design
earthworks and foundations for proposed structures
and for repair of distress to earthworks and
structures

3. PURPOSE OF SITE INVESTIGATION
1. Support planning and define the project feasibility.
2. Determine most economical and appropriate:
 Route and depth definition.
 Excavation and support methods definition.
3. Define physical characteristics of the soil, rock, and groundwater.
4. To minimize uncertainties of physical conditions for the bidder & to improve
safety.
5. Provide specific data needed to evaluate:
 Constructability, Cost, Productivity, Schedule.
• To document as:
 Built conditions of the completed project

4. INTRODUCTION OF PROBE MACKINTOSH
The site investigation is the one thing that must be done
before starting the construction of the building. This is
because the soil condition at the site need to
be identifies to determine the suitable foundation use for the
building and soil play a main role to support the load that come
from the building and the building
need a suitable foundation to transfer the load to the ground.
Therefore, the investigation of soil need to be
done to identify the type of soil to ensure the soil can
carry the load.

5. OBJECTIVE OF PROBE MACKINTOSH
• Collecting a disturbed soil sample for grain-size analysis and
soil classification
• Determine sub-surface straits graphed and identity materials
present
• Evaluate soil density and in-situ stress conditions
• Estimate geotechnical parameters

8. PROCEDURES
1. Equipment for the test is assembled. The cone diameter is measured in SI
unit.
2. Distance of 0.3 m is measured and marked on the rod start from the tip of
the cone
3. The equipment is set up on the ground
4. The hammer is pulled until it reached the maximum. The hammer is dropped
freely to driven the cone into the soils.
5. The sum of the number of blow for penetration of 0.3 m is recorded in the
data sheet.
6. The hammer is taken off on the last 0.3 of each rod and joined and existing
rod with another rod and lastly the hammer. The blow is continued and
stopped when :
 The blow is more than 400 for 0.3 m penetration
 The depth reached 15 m

18. CONCLUSION
JKR Probe Mackintosh is can be used to determine the thickness
of unsuitable material to be removed and also for preliminary
design of embankments, limited to about 15 m and must be
record no. of blows/ft. then correlates to established chart to
determine bearing capacity of soil. Mackintosh Probe which has
30° cone penetrometer while JKR Probes has 60° cone
penetrometer. This is a light dynamic test and the cone is driven
directly into the soil by driving a hammer 5 kg. Weight dropping
through a free height of 280mm. The probe is unable to
penetrate into medium strength soil and gravelly ground.
