INTRODUCTION:

It is proposed to construct nine, eight storey residential buildings

“Renaissance Royal” at the site. To assess the subsoil strata from safe

bearing capacity point of view, soil investigation work was entrusted to

Shree Samarth by Shree Sharda Infrastructure by work order.

SITE LOCATION:

The project area is located at Neral.Survey No.30/3

b,58/1B,60/2A2,,60/2 B, 60/2 K,60/2A3& Survey no.30/3 k, 59/1, 60/1,

61/2, , 59/1a,60/2A1

PROPOSED CONSTRUCTION:

It is proposed to construct nine, eight storey residential buildings. It

is anticipated that the structure shall be constructed from reinforced

concrete and the area around will be suitably land scapped.

SCOPE OF SERVICES:

The limited scope of services as defined in work order consists of

Drilling and sampling in nine boreholes (one borehole for each

building)

Carrying out relevant laboratory tests on representative soil

and rock samples.

Preparation of engineering report based on field and

laboratory data.

FIELD WORK:

Drilling and sampling in soil and rock was carried out using rotary

drilling rig. Borehole in soil was advanced using rotary drilling method,

while NX size core barrel with diamond bit was used to drill in rock.

Water was circulated to cool the drilling bit. Ground water table was

recorded after 24 hours of completion of drilling. On completion of

drilling, soil samples were packed in plastic containers with proper

identification tags. Rock cores were numbered and kept in core boxes.

Representative of client indicated location of bore holes.

Fieldwork was performed during February 2016.

Ground elevation as provided by client is tabulated below

SUB SOIL PROFILE

Sub-soil conditions described below are based on drilling and sampling in

nine boreholes. Generalized sub-soil profile for the area investigated can

be divided in various layers. It is possible that the layers encountered in

the borehole may not be in the same order as listed below. Following

table lists thickness of various layers, variation range of RQD as the case

may be.

Layer I: Brownish sandy gravel/ silty clay

Layer II: Completely weathered rock recovered as sandy grave

Layer III: Highly to slightly weathered basalt

Bore hole no

Layer I Layer II Layer IIIThick Thick Thick RQD

BH1 1.0 - 7.0 0-98

BH2 3.0 - 4.0 0-40

BH3 1.0 - 7.0 25-90

BH4 - 0.5 7.5 40-70

BH5 - 0.5 8.0 80-98

BH6 - 0.5 8.5 75-95

BH7 - 1.0 3.0 93-99

BH8 - 1.5 6.5 40-82

BH9 0.5 2.5 5.0 0-80

GROUND WATER LEVEL:

Water level was not encountered in any of the boreholes. Correct method

to determine ground water table is to install standpipe piezometer and

monitor over long period of time. Depth measured below the ground

surface existing at the time of investigation.

LABORATORY TESTING:

On completion of drilling samples were sent to the laboratory for

further testing. Samples were classified in the laboratory and

representative samples were selected for testing. Following tests were

performed.

Unconfined compression strength

Dry and soaked density

Porosity and absorption.

ENGINEERING ANALYSIS:

Engineering analysis of the substratum was performed to determine

net safe bearing capacity. Parameters obtained are based on various

field and laboratory tests.

Column loads are expected to be moderate to high. RQD and core

strength is considered up to bottom of borehole.

Safe baring capacity for foundations placed on rock is determined as

per procedure given in IS12070 “Code of practice for Design and

Construction of Shallow Foundations on Rock. The procedure is based on

RMR (Rock Mass Rating) concept. RMR is calculated as per the method

given in IS 13365 (Part 1) “Quantitative Classification System of Rock

Mass”. Determination of RMR takes into consideration following properties

of rock stratum

Strength of Intact rock material

Rock Quality Designation

Spacing of Discontinuities

Condition of Discontinuities

Ground water condition

Orientation of Discontinuities

Joint Orientation

It is mentioned in IS 12070 that if net allowable bearing capacity is

determined based on RMR “settlement of raft foundation upto 6m

thickness to be less than 12mm”.

IS code referred does not specify any limitation from type and width of

foundations placed on rock. Also IS code does not specify any factor of

safety used.

CONCLUSIONS AND RECOMMENDATIONS

Conclusions and Recommendations are based on following accepted

norms.

Foundations should not fail in shear.

Anticipated settlement shall be less than allowable value.

Net safe bearing capacity to be adopted for pad foundations to be placed

at different depth below the ground surface existing at the time of

investigation is tabulated below.

Bore hole no Foundation depth Net safe bearing capacity

BH-9

1.0m 30T/m2

2.0m 40T/m2

3.0m 285T/m2

Whenever foundations are placed on rock, it is essential to ensure that

there are no loose pockets on rock surface. In case of loose pockets or

over excavation, it shall be filled by plain cement concrete.

It is sound engineering practice to embed foundations for minimum

50cm in rock.

Shri Samarth Geotechnics takes this opportunity to thank staff of

Shree Sharda Infrastructure for their cooperation and support during

execution of this work.

Notes:

1. This report is issued based on the subsoil condition revealed at the

location of boreholes and laboratory tests performed on recovered

samples. If during construction of foundations it is observed that sub

soil conditions vary from those revealed during investigation it is

essential that Samarth Geotechnics shall be contacted so that on

confirmation supplementary report shall be issued.
