[ 1 ] INTRODUCTION : Shri Vipulbhai Charodia,Ahmedabad proposes geotechnical investigation work for a
building inVatva, Tal.: City, Dist : Ahmedabad in Gujarat state.
The purpose of the investigations was to determine the sub soil stratification of the soil,
geotechnical information & safe bearing capacity of the soil, so as to provide information that will
assist the structural engineers in the design of the foundations and the relevant works.
The Job was carried out under the guidance and supervision of the soil personnels of
G.I.C.E.A Laboratory,Ahmedabad, and client’s engineer.
[ 2 ] FIELD WORK : 1) Drilling two nos. of 150 mm dia borehole with casing whenever required up to maximum depth of 12.0 m from ground level. 2) Carryout standard penetration test at regular interval alternate to undisturb sampling 3) Collecting disturbed soil samples at regular interval as per the stratification of soil ,recording depth at which soil changes. 4) Collecting undisturbed samples (UDS) at regular interval alternate to SP Test or continuous UD samples at regular interval if subsoil is cohesive. [2.1] Borehole Drilling :
Drilling of 150 mm dia borehole was carried out by shell and Auger drilling method above
water table.Water was added while drilling but stopped at enough height above the test level to avoid
disturbance. Drilling below water table was made by percussion drilling method.casing is
required to be lowered if holes do not retain its shape.Care is taken to maintain ground water table
during drilling and particularly before testing or sampling levels.In no case casing is allowed to
advance below the bottom of borehole. Chiselling is carried out if required while drilling.The
Location of borehole was decided with due consideration of Client/Consultant of the project.
Report No.:1603-EI324-06-Vatva

(2.2) Collection of Samples:
Undisturbed soil samples in 38mm Ø shelby tubes were collected in the thin walled sampling
tubes in accordance with IS:2132-1981at regular interval for finding shear parameters, field density,
moisture content etc. of soil.The sampling tube was connected to the rod by jarring link in case of
38mm Ø tubes.’A’ drill rods were connected by suitable adaptor with ball check value. Before
lowering the sampler ,the borehole was cleaned properly and sampling tubes were lightly oiled from
inner and outer side.
Sampling tube was pushed into the borehole by pressure hammering as per the soil stiffness.
The sampling tubes were waxed immediately after removal.
In case of medium to coarse grained ,non-cohesive sand samples,where sampling is
unsuccessful,Standard Penetration Tests was carried out after cleaning the borehole.
However, disturbed soil samples from shell or split spoon samplers were also collected in
polythene bags with proper levels during drilling for finding index properties of the soil.
[ 2.3 ] Standard Penetration Test :
The standard penetration tests were performed in accordance with IS:2131:1981 using the
standard split spoon sampler & 63.5Kg hammer at the desired intervals. Before testing ,the borehole
was cleaned properly and Split spoon sampler was centrally seated in the borehole.In case of SPT to
be conducted below water table,care was taken to keep casing position above the borehole
depth..The water level in borehole is maintained above or at least at the water table.
A standard hammer of 63.5 kg is dropped from a height of 75 cms. And the no. of
blows for penetration of sampler for 0-15,15-30 and 30-45 cms were noted in table no.3.
Standard penetration test value Ns is considered for last 30 cm penetration,For non plastic silts
and fine sands Ns value is corrected for effective overburden pressure and dilatancy.Correction is
applied for tests conducted below water table.

[ 3 ] LABORATORY WORK
Following laboratory tests were carried out on the samples collected from the site.
1. Water content on selected samples from SPT
2. Field density,Moisture content and dry density of undisturbed samples.
3. Grain size Analysis of SPT samples,.UD samples and disturbed samples
covering each soil strata.
4. Atterberg’s Limit for samples
5. Specific gravity Test for samples as per 3.
6. Shrinkage Limit / Free Swell / Differential Swell test for selected samples of
expansive soil
7. Test for shear properties of selected samples.
8. Unconfined compressive Strength on saturated cohesive soil
9. Triaxial Shear test under UU/CU condition with or without pore pressure measurement as
per in situ conditions.Normally soft cohesive saturated samples will be consolidated at average
overburden pressure.
The common practice adopted in the field and laboratory testing by & large are as per I S
code indicated . Results of the laboratory tests performed on various soil samples are presented in the
form of table at the end of report.
[ 4 .0] PHYSICAL PROPERTIES:- The moisture cans collected from SPT samplers from the field are weighed and placed in
oven for drying to determine natural moisture content(NMC). Results are tabulated in table-3
UDS are extracted using screw type extractor and samples were prepared as per the
required size of the test. Weight and volume of the samples were noted before extracting from
tubes.Average bulk density is calculated and samples were placed in oven to get the field moisture
content for computing the dry density.Results are tabulated in table 4.
Report No.:1603-EI324-06-Vatva

Specific gravity with specific gravity bottle/pycnometer is calculated as per IS
2720.Results were tabulated in table4.Saturation of sample in % is also calculated which is a
useful data for deciding the condition of triaxial shear test.
Grain size analysis is made by IS sieves of sizes 4.75mm,2.00mm,1.00mm,0.425mm,0.25mmand
0.075mm.For coarse grained soil a graph of partical size v/s cumulative % finer is plotted.
For fine grained soil wet analysis is made on plummet balance.Results are tabulated in table 5
Liquid limit and Plastic Limit tests are carried out with distilled water as per IS 2720
part – 5.The samples are tested at a minimum of 24 hours after the addition of water. Liquid limit
is done on casagrande standards with occasional checking by Cone penetration method.
The soil samples showing high plasticity were checked for swelling and shrinkage.
Firstly for rough estimate,free swell test is carried out as per IS 2720 part – 40.Shrinkage limit test is
carried out as per is 2720 part 6.
[5.0] SHEAR PROPERTIES:-
Shear tests were carried out by three methods.
1) Unconfined compressive strength as per IS 2720 part-10 for the saturated plastic soil
2) Triaxial shear test is tobe carried out on samples of size 38mm dia and 76 mm in height
on motorized 30 speed load frame .The confining pressure б3 is applied to the cell by oil
water constant pressure system. The tests are carried out for the three conditions
a) Unconsolidated Undrained (UU) test without pore water pressure measurement as per
IS 2720 part 1
b) Consolidated Undrained (CU) test without pore water pressure measurement as per
IS 2720 part 11
The condition decided on type of sample and water table condition or designers
specifications.
c) Direct/box shear test on noncohesive medium to coarse sandy soil as per IS 2720 part
13. The graph for triaxial shear test is plotted by modified method .

Annexure 8: Environmental Management Plan 1.0 Structure of EMP
Environmental Management Plan (EMP) is the key to ensure a safe and clean environment. The desired results from the environmental mitigation measures proposed in the project may not be obtained without a management plan to assure its proper implementation & function. The EMP envisages the plans for the proper implementation of mitigation measures to reduce the adverse impacts arising out of the project activities. EMP has been prepared addressing the issues like:
• Pollution control/mitigation measures for abatement of the undesirable impacts caused during the
construction and operation stage • Details of management plans (Landscape plan, Solid waste management plan etc.) • Institutional set up identified/recommended for implementation of the EMP • Post project environmental monitoring programme to be undertaken • Expenditures for environmental protection measures and budget for EMP
2.0 Proposed Environmental Mitigation Measures
The major impacts due to different project activities were identified during the EIA study. The mitigation measures proposed for the impacts constitute the part of Environmental Management Plan (EMP). The environmental mitigation measures for construction and operation phases have been given in Table1.
Table 1. Proposed Environmental Mitigation Measures
Area Mitigation Measures Construction Stage: Water quality • Toilet and drinking water facilities for construction workers are provided by the
contractor at the construction site to avoid unhygienic condition at site. Air quality • Dust suppression measures are undertaken such as regular sprinkling of water
around vulnerable areas of the construction site by suitable methods to control fugitive dust during earthwork and construction material handling/ over hauling.
• Properly tuned construction machinery & vehicles in good working condition with low noise & emission are used and engines are turned off when not in use.
Noise level • Protective gears such as ear mufflers etc. are provided to construction personnel exposed to high noise levels.
Solid wastes • Waste construction materials are recycled and excess construction debris are disposed at designated places in tune with the local norms.
Landscape • Appropriate landscape including plantation of evergreen and ornamental flowering trees, palms, shrubs and ground covers at open spaces within the complex will be done, which would serve the dual purpose of controlling fugitive dust and improving the aesthetics of the area.
Safety • Adequate safety measures complying to the occupational safety manuals are adopted to prevent accidents/hazards to the construction workers.
Operation Stage: Water quality • Wastewater will be collected and disposed into municipal line.
two number of rainwater harvesting recharge wells will be developed Air quality • Trained staff will be handle traffic movement
• Regular monitoring of ambient air quality will be carried out as per norms. Solid wastes • Solid wastes will be segregated into organic and inorganic components.
• The recyclable inorganic wastes will be sold to prospective buyers. • The bio-degradable wastes will be disposed near by municipal bins.
Rainwater harvesting
• Adequate rainwater harvesting will be provided
Fire protection • Adequate fire protection facilities will be installed including fire detectors, fire alarm and fire fighting system as per National Building Code of India.
Landscape • Proper maintenance of landscape round the year including replacement of the decayed plants.
Safety • Adequate safety measures complying to the occupational safety manuals to prevent accidents/hazards to the maintenance workers.
Others • The building will be provided with disabled-friendly design, timber-free construction, energy efficient lighting & ventilation, and control of indoor
environment.
3.0 Environmental Monitoring Plan
It is imperative that the Project Authority set up regular monitoring stations to assess the quality of the surrounding environment after the commissioning of the project. An environmental monitoring programme is important as it provides useful information and helps to: • Verify the predictions on environmental impacts presented in this study, • Assist in detecting the development of any unwanted environmental situation, and thus, provides
opportunities for adopting appropriate control measures, and • Evaluate the performance and effectiveness of mitigation measures proposed in the EMP and
suggest improvements in management plan, if required, • Satisfy the legal and statutory obligations. The post project monitoring plan including areas, number and location of monitoring stations, frequency of sampling and parameters to be covered is summarized in Table 2. The monitoring will be the responsibility of EMC.
Table 2: Environmental Monitoring Plan Source Monitoring Location Parameters to be
Monitored Frequency
Ambient Air Quality At 3 locations (1 inside the complex and 2 outside in surrounding 1 km zone along predominant wind directions)
PM10, PM2.5, SO2, NOxOnce in a season and as per requirement of SPCB
Ambient Noise At 3 locations (1 inside the complex and 2 outside in surrounding 100 m zone)
Day and night equivalent noise level
Once in a season and as per requirement of SPCB
Stack Stack PM, SO2, NOx, CO Once in a season and as per requirement of SPCB
The post operational monitoring schedule will be under the supervision of the Site Engineer at the project site. Monitoring will be carried out by recognized laboratories.
4.0 Environment Management Cell An Environment Management Cell (EMC) will be responsible for implementation of the post project-monitoring plan for this project. The composition of the Environment Management Cell and responsibilities of its various members are given in Table 3.

6.0 General Principles in Greenbelt Design Plants grown in such a way so as to function as pollutant sinks are collectively referred as greenbelt. These plants should also provide an aesthetic backdrop for persons using the site and for the surrounding community. General principles in greenbelt design considered for this study are:
Type of pollution (air, noise, water and land pollution) likely from the activities at the site
Semi arid zone and sub-zone where the greenbelt is located (and hence the plant species which can be planted in the area).
Water quantity and quality available in the area
Soil quality in the area
Greenbelt is designed to minimize the predicted levels of the possible air and noise pollutants. While designing the scheme the following facilities are considered:
Site perimeter and approach road
Along the internal roads
In and around the building area
To ensure a permanent green shield around the periphery planting is recommended in two phases.
In the first phase one row of evergreen and fast growing trees (which grows up to 10-15m) with maturity period of around three years shall be planted at 3.0 meter interval along with fast growing ground covers to enhance the water holding capacity, improve the organic content and check the soil erosion.
In the second phase after eighteen months, second row of trees with large leaf surface area with large ever green canopy and longer life span shall be planted at 6.0 meters intervals.
6.1 Greenbelt Design for Site The selection of the trees is based on their phenology (thus road side trees will not have leaf fall during summer and rainy seasons when shade is most needed). Trees with more litter fall have been avoided.
The selection criteria of the species are based on pollution mitigation capacity (including particulate matter), large leaf surface area to deep root system and less litter fall. Faster growing trees with lighter canopy will be planted alternatively with relatively slow growing trees with wider canopy. Trees of about 6.0 m heights will be planted at 4.5 m intervals, 2.5 m away from the road curbing as per CPCB guidelines. Trees will be planted along the outer periphery at centerline of road between the set back line and the boundary of the plots. Palms and shrubs will be planted along the roads and around recreational lawns.
6.2 Greenbelt Management It is presumed that the selected plants will be grown as per normal horticultural practice and the authorities responsible for the plantation will make adequate provisions for water and protection of the saplings. A budgetary cost estimate is also prepared for greenbelt development.
Water source Water tankers may also be used at the initial stages of development of the plant.
Irrigation method Water hydrants may be installed at 50 m intervals to irrigate area under shrubs and ground covers.
6.3 Improving Indoor Air Quality The indoor air quality can be improved by any of the following:
Ventilation
Include the use of natural, dilution, local exhaust, or increased ventilation efficiency. The most effective engineering control for prevention of indoor air quality problems is assuring an adequate supply of fresh outdoor air through natural or mechanical ventilation.
When possible, use local exhaust ventilation and enclosure to capture and remove contaminants generated by specific processes. Room air in which contaminants are generated should be discharged directly outdoors rather than recirculated.
Outside air intakes should not be located in close proximity to potential sources of contamination (automobile garages, building exhausts, and roadways).
Work Place Recommendations
Eliminate or control all known and potential sources of microbial contaminants by prompt cleanup and repair of all areas where water collection and leakage has occurred including floors, roofs, drain pans, humidifiers containing reservoirs of stagnant water, air washers etc.
Remove and discard porous organic materials that are contaminated (e.g., damp insulation in ventilation system, ceiling tiles, and carpets).
Clean and disinfect non-porous surfaces where microbial growth has occurred
Maintain indoor air relative humidity below 60%
Adjust intake of outdoor air to avoid contamination from nearby soil, vegetable debris unless air is adequately conditioned.
Isolate, if feasible, areas of renovation, painting, carpet laying, pesticide application, etc., from occupied areas that are not under construction.
Supply adequate ventilation during and after completion of work to assist in diluting the contaminant levels.
Eliminate or reduce contamination of the air supply with cigarette smoke by banning smoking or restricting smoking to designated areas which have their air discharged directly to the outdoor rather than recirculated.
6.4 Safety Aspects of the Project The following needs to be implemented:
Fall Protection
The Contractor is required to provide fall protection to employees who are working at heights equal to or greater than 1.8 m. fall protection can be in the form of perimeter protection such as guardrails and toe rails, personal protective equipment (PPE), a safety monitoring system, or a fall protection plan. Activities that require personal fall protection systems include steel erection bolting, riveting, fitting-up and plumbing-up, work over water and some deep excavation work.
On buildings or structures not adaptable to temporary floors, and where scaffolds are not used, safety nets will be installed and maintained whenever the potential fall distance exceeds two storey.
The PPE standard should cover occupational foot, head, hearing, and eye protection.
Foot Protection: If machines or operations present the potential for foot injury, the Contractor must provide foot protection, which is of safe design and construction for the work to be performed. Workers and visitors should not be allowed on a construction site without safety boots.
Head Protection: If head hazards remain after all steps have been taken to control them (safety nets for work at heights, proper housekeeping), the Contractor must provide employees with appropriate head protection.
Noise Protection: Workers should be wearing hearing protection devices (ear plugs, ear muffs, canal caps) that are in good condition whenever they are involved in noisy activities.
Eye Protection: When machines or operations present potential eye injury from physical or chemical elements, the Contractor must select, provide, maintain and required affected employees to use appropriate eye protection. Eye protection (safety glasses and goggles, face shields and welding helmets) must be adequate and reasonably comfortable.
To the greatest extent possible, working surfaces must be kept dry to prevent slips and falls and to reduce the chance of nuisance odors from pooled water.
All equipment and materials should be stored in designated storage areas that are labeled as such.
Ladders and Stairs
The Contractor is required to inspect and maintain all ladders and temporary/portable steps to ensure that they are in good working condition.
Portable ladders used for access to an upper landing surface must extend a minimum of 1.8 m above the landing surface, or where not practical, be provided with grab rails and be secured against movement while in use.
All ladders must be used only on stable and level surfaces unless secured to prevent accidental movement. Ladders must not be used on slippery surfaces unless secured or provided with slip-resistant feet to prevent accidental movement.
The Contractor should provide a ladder (or stairway) at all work points of access where there is a break in elevation of 0.5 m or more.
When there is only one point of access between levels, it must be kept clear to permit free passage by workers. If free passage becomes restricted, a second point of access must be provided and used. At all times, at least one point of access must be kept clear.
All required stairway and ladder fall protection systems must be provided and installed before employees begin work that requires them to use stairways or ladders.
Scaffolds
Access to Scaffolds - access to and between scaffold platforms more than 0.6 m above or below the point of access will be made by portable/attachable ladders or ramps.
Employees must never use makeshift devices, such as boxes and barrels, to increase the scaffold platform working level height.
Trenching and Excavation
The area around the trench/excavation would be kept clear of surface encumbrances.
Water should not be allowed to accumulate in the excavation.
Adjacent structures would be shored in accordance with the design documents to prevent collapse.
Guardrails or some other means of protecting people from falling into the trench/excavation would be present.
The trench or excavation would be shored or sloped to prevent cave-ins.
Electrical Safety
If work has to be done near an overhead power line, the line must be de-energized and grounded before work is started.
A licensed electrician would have completed all temporary wiring and electrical installations required for construction activities.
Fuses and circuit breakers would be used to protect motherboards, conductors and equipment.
Extension cords for equipment or as part of a temporary wiring system will not be damaged or compromised in any way and insulation must be of the highest grade.
Anytime electrical equipment is deactivated for repair, or circuits are shut off, the equipment will be locked out and tagged at the point where it can be energized.
Temporary lights may not be suspended by their cords.
The Contractor would provide the necessary safety equipment, supplies and monitoring equipment to their personnel.
Cranes A competent person has been designated to supervise activities that require the use of cranes. Cranes would not be operated near any power lines. All picks would be carefully planned to ensure that the crane adequately hoist the load. The hoisting signals would be posted on the exterior of the crane.
Occupational Noise Exposure
The Contractor should implement engineering controls to reduce noise levels.
The Contractor should provide hearing protection to employees that are exposed to noise levels above the permissible limit.
Welding and Cutting
The Contractor's employees would be trained in hot work procedures.
There should be adequate ventilation to reduce the build up of metal fume.
The hot work operators would use proper personal protective equipment (i.e., welding helmet, burning goggles, face shield, welding gloves, and apron).
There would be a fire extinguisher present at all welding and burning activities.
Extinguishers would also be placed at locations where slag and sparks may fall.
Oxygen and flammable gas bottles are separated by at least 7 m when not in use.
The Contractor would control the release of gases, vapors, fumes, dusts, and mists with engineering controls (e.g., adequate ventilation).
General Guidelines
Signs and symbols would be visible during any construction activity that presents a hazard. Upon completion of such activity, the postings must be removed immediately.
The Contractor would post specific DANGER signs when an immediate hazard exists and specific CAUTION signs when the potential for a hazard exists. EXIT, NOTICE and specific safety signs may also be posted in the work area.
Signage for traffic control, including directional signs, is applicable when the Contractor is disrupting traffic along a public way.
Danger signs are posted at all immediate hazards (i.e. Danger: Open Hole).
Caution signs are posted at all potential hazards (i.e. Caution: Construction Area, Caution: Buried Cable).
The floor that is being used as the erection floor must be solidly planked or decked over its entire surface except for access openings.
Every floor, working place and passageway would be kept free from protruding nails, splinters, holes or loose boards.
Combustible scrap and debris (wood, clearing/grubbing material) would be removed from the site daily or should be securely stored in covered containers.
The Contractor would have a spill prevention control and countermeasure plan that limits the risk of releases of oil or hazardous materials to the environment.
