Rotary drilling is the most rapid method of advancing the boreholes in any type of soil. This method uses rotation of drill bits (tungsten), with the simultaneous application of pressure to advance the borehole. The drilling/boring works at the near-shore locations were carried out by deploying modular jack-up barge KRISHNA with leg length of.m. A hydraulic drilling rig with triplex pump, power winch, accessories and tools for drilling were mounted on jack-up barge KRISHNA. The boreholes and jackup were positioned at specified locations using SIMRAD MX DGPS. Modular jack-up was shifted from one borehole location to other using tug boat. The boring / drilling operations were carried out by hydraulic rotary drilling method using jack up platform. Disturbed soil samples were obtained through a split spoon sampler during execution of Standard Penetration Tests (SPT). The borehole walls are supported by temporary steel casing driven until a hard stratum is encountered or until reaching of termination depth of the borehole. Clear water was used as the flushing medium. Fugro Document No. - Page of 9

10 Department of Ports & Inland Water Transport, Karnataka Geotechnical Investigation Work For nd Stage Development of Karwar Commercial Port, KARNATAKA, INDIA The drilling/boring works at the on-shore location (BH-7) were carried out by using a Rotary drilling rig. Disturbed soil samples were obtained through a split spoon sampler during execution of Standard Penetration Tests (SPT). The borehole walls are supported by temporary steel casing driven until a hard stratum is encountered or until reaching of termination depth of the borehole. Bentonite water slurry was used as the flushing medium. Standard penetration tests (SPT) were carried out by driving split barrel sampler complete with a drive shoe and drive head fitted with a non-return valve. The test is carried out in general accordance with IS 3. The basis of the test consists of dropping of a hammer of mass 3. kg on to a drive head from a height of 7 mm. The number of such blows (N) necessary to achieve a penetration of the split spoon sampler by 3mm is regarded as the penetration resistance. The blow counts for each mm penetration were recorded. Small, disturbed samples of soil were obtained from the split spoon sampler after completion of the tests. On reaching the rock strata, rock core samples were obtained using double tube core barrel. The boreholes were terminated on reaching the requisite depth as per the instruction of Engineer In-charge. The quantitative description of natural fracture state of rock masses are indicated using a number of indices as determined from the borehole cores. These indices are described as TCR, SCR and RQD. Total Core Recovery (TCR) is the percentage ratio of core recovered (whether solid, intact with full diameter, or non-intact) to the total length of core run. Solid Core Recovery (SCR) is the percentage ratio of solid core recovered to the total length of the core run. Rock Quality Designation (RQD) is a quantitative index based on core recovery procedure that incorporates only those pieces of core which are mm or more in length. It is the total length of solid core pieces, each greater than mm between natural fractures, expressed as a percentage of the total length of core run. It is also a measure of drill core quality and it disregards the influence of orientation, continuity, joint thickness and gauge. The geotechnical borehole logs with visual lithologs, SPT N values and incorporating the laboratory test results carried out as per the laboratory test schedule approved by the Engineer-In-Charge and as per the technical specifications of the contract, are presented in Appendix C on Plates C through C3. Various legends used in borehole logs are presented in Illustrations on Plate B3. Sub-surface borehole profiles were prepared by taking various lines of sections and presented Illustrations on Plates B. and B.. Fugro Document No. - Page 7 of 9

15 GUIDE FOR USE OF REPORT INTRODUCTION This document provides guidelines, recommendations and limitations regarding the use of information in this report. The cost of geotechnical data acquisition, interpretation and monitoring is a small portion of the total cost of a construction project. By contrast, the costs of correcting a wrongly designed programme or mobilising alternative construction methods are often far greater than the cost of the original investigation. Attention and adherence to the guidelines and recommendations presented in this guide and in the geotechnical report can reduce delays and cost overruns related to geotechnical factors. This guide applies equally to the use of geotechnical and multi-disciplinary project information and advice. REQUIREMENTS FOR QUALITY GEOTECHNICAL INFORMATION Fugro follows ISO 9 quality principles for project management and ISO 39 for general principles on reliability for structures. Project activities usually comprise part of specific phases of a construction project. The quality plan for the entire construction project should incorporate geotechnical input in every phase - from the feasibility planning stages to project completion. The parties involved should do the following: Provide complete and accurate information necessary to plan an appropriate geotechnical site investigation. Describe the purpose(s), type(s) and construction methods of planned structures in detail. Provide the time, financial, personnel and other resources necessary for the planning, execution and follow-up of a site investigation programme. Understand the limitations and degree of accuracy inherent in the geotechnical data and engineering advice based upon these data. During all design and construction activities, be aware of the limitations of geotechnical data and geotechnical engineering analyses/advice, and use appropriate preventative measures. Incorporate all geotechnical input in the design, planning, construction and other activities involving the site and structures. Provide the entire geotechnical report to parties involved in design and construction. Use the geotechnical data and engineering advice for only the structures, site and activities which were described to Fugro prior to and for the purpose of planning the geotechnical site investigation or geotechnical engineering analysis programme. AUTHORITY, TIME AND RESOURCES NECESSARY FOR GEOTECHNICAL INVESTIGATIONS Fugro 99- ISSUE Adequate designation of authority and accountability for geotechnical aspects of construction projects is necessary. This way, an appropriate investigation can be performed, and the use of the results by project design and construction professionals can be optimised. Figure illustrates the importance of the initial project phases for gathering adequate geotechnical information for a project. The initial phases, when site investigation requirements are defined and resources are allocated, are represented by more than % of the Quality Triangle (Figure ). Decisions and actions made during these phases have a large impact of the outcome and thus the potential of the investigation to meet project requirements. Page of 3

16 GUIDE FOR USE OF REPORT Figure : Quality of Geotechnical Site Investigation (adapted from SISG ). PEOPLE CLIENT / PRINCIPAL TECHNICAL ADVISER PRINCIPAL TECHNICAL / GEOTECHNICAL ADVISER GEOTECHNICAL ADVISER / SPECIALIST GEOTECHNICAL SPECIALIST S.I. REQUIREMENTS PERCEIVED DEFINITION OF NEEDS PLANNING, RESOURCES, TIME SPECIFICATION TASKS ILL-DEFINED TASKS DRILLING / FIELD TESTING CONTRACTORS TECHNICIANS FIELD WORK LAB. TESTS GEOTECHNICAL ADVISER / SPECIALIST ASSESSMENT AND DRAFT REPORT INCREASINGLY PRESCRIBED THE POTENTIAL FOR INADEQUACY IS BROADLY PROPORTIONAL TO THE AREA OF THE TRIANGLE REPRESENTED BY A TASK DATA ACQUISITION AND MONITORING PROGRAMMES Geotechnical investigations are operations of discovery. Investigation should proceed in logical stages. Planning should allow operational adjustments deemed necessary by newly available information. This observational approach permits the development of a sound engineering strategy and reduces the risk of discovering unexpected hazards during or after construction. GEOTECHNICAL INFORMATION DATA TYPES AND LIMITATIONS. RELIABILITY OF SUPPLIED INFORMATION Geotechnical engineering can involve the use of information and physical material that is publicly available or supplied by the Client. Examples are geodetic data, geological maps, geophysical records, earthquake data, earlier geotechnical logs and soil samples. Fugro endeavours to identify potential anomalies, but does not independently verify the accuracy or completeness of public or Client-supplied information unless indicated otherwise. This information, therefore, can limit the accuracy of the report.. COMPLEXITY OF GROUND CONDITIONS FOCUSSED & RELEVANT INFORMATION FOR USE BY PROFESSIONAL / ADVISER THE REPORT There are hazards associated with the ground. An adequate understanding of these hazards can help to minimize risks to a project and the site. The ground is a vital element of all structures which rest on or in the ground. Information about ground behaviour is necessary to achieve a safe and economical structure. Often less is known about the ground than for any other element of a structure. 3. GEOTECHNICAL INVESTIGATION - SPATIAL COVERAGE LIMITATIONS Geotechnical investigations collect data at specific test locations. Interpretation of ground conditions away from test locations is a matter of extrapolation and judgement based on geotechnical knowledge and experience, but actual conditions in untested areas may differ from predictions. For example, the interface between ground materials may be far more gradual or abrupt than a report indicates. It is not realistic to expect a geotechnical investigation to reveal or anticipate every detail of ground conditions. Nevertheless, an investigation can reduce the residual risk associated with unforeseen conditions to a tolerable level. If ground problems do arise, it is important to have geotechnical expertise available to help reduce and mitigate safety and financial risks.

17 GUIDE FOR USE OF REPORT. ROLE OF JUDGEMENT AND OPINION IN GEOTECHNICAL ENGINEERING Geotechnical engineering is less exact than most other design disciplines, and requires extensive judgement and opinion. Therefore, a geotechnical report may contain definitive statements that identify where the responsibility of Fugro begins and ends. These are not exculpatory clauses designed to transfer liabilities to another party, but they are statements that can help all parties involved to recognise their individual responsibilities and take appropriate actions. COMPLETE GEOTECHNICAL REPORT SHOULD BE AVAILABILE TO ALL PARTIES INVOLVED To prevent costly construction problems, construction contractors should have access to the best available information. They should have access to the complete original report to prevent or minimize any misinterpretation of site conditions and engineering advice. To prevent errors or omissions that could lead to misinterpretation, geotechnical logs and illustrations should not be redrawn, and users of geotechnical engineering information and advice should confer with the authors when applying the report information and/or recommendations. GEOTECHNICAL INFORMATION IS PROJECT-SPECIFIC Fugro s investigative programmes and engineering assessments are designed and conducted specifically for the Client described project and conditions. Thus this report presents data and/or recommendations for a unique construction project. Project-specific factors for a structure include but are not limited to: location size and configuration of structure type and purpose or use of structure other facilities or structures in the area. Any factor that changes subsequent to the preparation of this report may affect its applicability. A specialised review of the impact of changes would be necessary. Fugro is not responsible for conditions which develop after any factor in site investigation programming or report development changes. For purposes or parties other than the original project or Client, the report may not be adequate and should not be used. CHANGES IN SUBSURFACE CONDITIONS AFFECT THE ACCURACY / SUITABILITY OF THE DATA Fugro 99- ISSUE Ground is complex and can be changed by natural phenomena such as earthquakes, floods, seabed scour and groundwater fluctuations. Construction operations at or near the site can also change ground conditions. This report considers conditions at the time of investigation. Construction decisions should consider any changes in site conditions, regulatory provisions, technology or economic conditions subsequent to the investigation. In general, two years after the report date, the information may be considered inaccurate or unreliable. A specialist should be consulted regarding the adequacy of this geotechnical report for use after any passage of time. Page 3 of 3
