BRIEF SPECIFICATIONS AND SCOPE OF WORK
1. GENERAL
1.1 All soil investigation work must be carried as per relevant Indian Standards for subsurface investigations (IS
1892), classification of soils (IS 1498), determination of bearing pressures for shallow foundations (IS 6403),
pile foundations (IS 2911) and various other Standards specified for the sampling, tests and recommendations.
For laboratory testing of rock samples, methods suggested by International Society of Rock Mechanics (ISRM)
shall be followed.
1.2 All levels shall be recorded from a fixed bench mark identified by the Architects.
1.3 Tentative locations of the boreholes are marked on the enclosed drawing.
1.4 Soil Investigation Agency shall keep the structural consultants informed about the progress of work at site and
shall furnish clarifications if required.
1.5 The time limit for completing soil investigation work is three weeks from the date of receipt of the Work-Order.
2. SCOPE OF INVESTIGATION
Total number of boreholes will be 5 Nos. as shown in the drawing.
The scope of Soil Investigation work shall definitely include (but shall not be limited to) the following:
2.1 Drilling all 5 bore holes up to at least 20.0m depth below the existing ground level or 10m depth below weathered
rock level – whichever is more and collecting disturbed and undisturbed samples at suitable intervals (and at
change of strata) and recording Standard Penetration Test results.
2.2 Carrying out laboratory tests on the 5 samples collected to determine Engineering Properties of Soil as directed
by the Consulting Engineers.
2.3 Carrying out chemical analysis of one sample of the ground water and two samples of the soil to determine
chloride and sulphate contents and pH value.
2.4 Recording existing ground water table and the extent of fluctuation, if any, in ground water table level.
2.5 Indicating the permeability of soil to determine the feasibility of carrying out open excavation up to 10m depth,
if required.
3. RECOMMENDATIONS
3.1 The Soil Investigation Agency is expected to make recommendations on each type of Foundation, Depth of
Foundation and Net Allowable Bearing Pressure on the soil at different levels. The expected short-term and longterm settlements for the recommended bearing pressures shall be clearly spelt out.
3.2 In case of piled foundations, load carrying capacities of driven as well as bored & cast in situ piles taking into
account the structural capacity of the pile shaft as well as the resistance offered by surrounding soils by means
of side friction and the tip resistance shall be calculated. The report should mention the capacities of piles in
relation to their diameters and the length of piles.
3.3 For all recommendations, the formulae in Indian Standards shall be used or any established literature can be
consulted. The Soil Investigation agency shall give complete calculations to the structural consultants showing
the basis of the recommendations on field and laboratory tests. The criteria for determination of quality of
acceptable strata shall be clearly defined in a manner, which will assist the supervisory staff at site during the
progress of work.
3.4 The investigation agency shall recommend values of suitable ‘spring constants’ to be adopted in the analysis to
determine the soil structure interaction. Similarly values of approximate ‘horizontal spring constants’ shall be
recommended.
3.5 The investigation agency shall visit the site atleast twice during the initial stages of actual construction work of
the project, whenever it is taken up, to confirm the acceptance of the founding strata as well as its load carrying
capacity, in accordance with the results of soil investigation it has submitted.
3.6 The investigating agency shall include in the report, the safe slope of excavation needed to be maintained
throughout the work for different depths of excavation from 1m upto 12m depending on the soil properties in
different layers.
3.7 The report should also indicate the need to install a soil retention system including dewatering, if required, and
the recommended type of such a system keeping in view if excavation levels may reach a depth of 12m.
3.8 A cross section of soil profile covering the bore holes along both the axes shall be included in the report.
