6 of 49 Construction of Giresun Wastewater Treatment Plant  Tender Dossier Volume 3 Employer’s Requirements  Section 05: Earth Works, Pipe Works and Ground Improvement   TS 1500 Classification of soil for civil engineering purposes   TS 1901 Methods of obtaining disturbed and undisturbed samples for civil engineering pur- poses   TS 3440 Rules for making concrete exposed to aggressive effects of liquids, soils and gases   TS 5744 In situ measurement methods of the properties of foundation soils in civil engineer- ing   TS 6108 Terms used in engineering geology   TS EN 206-1 Concrete - Part 1: Specification, performance, production and conformity  5.1.3 Geotechnical report and ground improvement  The Contractor shall submit to the Engineer, a Soil Investigation and a Geotechnical Report incorpo- rating a record of all the investigation work carried out by him. The Report shall include boring logs,  borehole coordinates, records of field and laboratory tests, records of water level observations and rec- ommendations as to the bearing capacity and deformation properties of the soil and water inflow. The  report shall be prepared in English. Five copies of this Report shall be submitted to the Engineer with- in one month of completing the field work. Laboratory tests shall be carried out in the laboratory ap- proved by the Engineer.  The report shall cover the following for each and every structure,  ultimate and allowable bearing capacity of foundation soil   liquefaction analysis   drainage system of excavations   immediate and consolidation settlements, and heave at excavations   single pile capacity (if necessary)   ground improvement design (if necessary).  5.1.4 Tests on ground water  During the course of the work the Engineer will require samples of the ground water to be taken for  testing to ascertain the present of harmful substances. The testing shall take place in accordance with  TS 3440.  The tests shall be performed in the beginning of the execution works in the laboratory on site before  starting any concrete work. The results concerning adverse effects on concrete shall be evaluated ac- cording to TS EN 206 Section 4.  The Contractor shall use the data in the documents and results of the site investigations to design in  detail every aspect of the Works, permanent or temporary, which is affected by the subsoil. This sta- bility of design shall be entirely the Contractor’ responsibility, however design is subject to the ap- proval by the Engineer.  The site investigations and the geotechnical evaluations attached to the document are subject to change  according to the plant structures and layout in the actual plant design. The surveys are given only for  information purpose. The Contractor shall conduct new site and soil investigations according to the  locations, dimensions, foundation depths and weights of the structures in his detailed design. The  foundation, ground stability should be complied with Section 5.4 and 5.5.  5.1.5 Design of structures  5_Vol3_d4.3_Section 5 Earth and pipe works_en_GIR_rev6.docx
