LTD. 1.0 INTRODUCTION Adani Ports and SEZ Limited (APSEZL) desires that detailed off-shore geotechnical investigation be carried out in proposed Dry Bulk Terminal Location in Tuna, Kandla, in proposed jetty location and along the approach trestle and rock bund, to provide the designer with sufficiently accurate information, both general and specific, about the substrata profile and relevant soil and rock parameters at site on the basis of which the foundations for various structures and equipments can be designed rationally. APSEZL has signed a concession agreement with Kandla Port Trust for developing of a Dry Bulk Terminal off Tekra near Tuna outside Kandla creek at Kandla Port on BOT Basis. APSEZL has formed a wholly owned subsidiary named Adani Kandla Bulk Terminal Pvt. Ltd. (AKBTPL) for the development of the terminal. AKBTPL [hereafter “Client”] of Ahmedabad (Gujarat), India have contracted Fugro Geotech Pvt. Ltd. (FGTL) [hereinafter “Fugro”], of Navi Mumbai (Maharashtra), India to perform near shore soil investigation work for the jetty and approach trestle at Tuna, Kandla vide Service Order No: 5700079294 dated 02.10.2012. The project consists of development of the off-shore berthing structure with allied facilities for handling dry bulk cargo. All the geotechnical investigation works were carried out according to relevant Indian, British and American or equivalent Standards. This report describes the factual field and laboratory data obtained through the geotechnical investigation campaign in accordance with the requirements of the technical specifications. This report also discusses about the foundation recommendations for the proposed marine construction, all as per the requirement of technical specification. Fugro Report No.: FGTL/AKBTPL/ED/452/12/REV-4 8 FUGRO GEOTECH PVT. LTD. 2.0 SCOPE OF WORK The scope of works for the geotechnical investigation is to perform a total of ten (10-nos) boreholes at proposed jetty head locations, along approach trestle and rock bund locations. The work entails carrying out a campaign of sub-soil investigation work includes following; • Mobilization of machinery and manpower along with the Jackup “Fugro GANGA”, mounted with hydraulic drill rig, water pump, testing tools, accessories, power pack, store house, PCPT set etc. to carry out marine boreholes and in-situ tests • Survey and precise positioning of the borehole locations using Leica 420MX DGPS. • Floating out and shifting of the jack up barge from one borehole location to other using tug boat. • Sinking of 10 numbers of marine boreholes at specified
