The incessant incidence of building failures is becoming alarming and has led to the loss of life and assets. These failures have been attributed to factors such as inadequate information about the subsurface geological material, poor foundation design, and poor building materials. (OyedeleKayode Festus et. al, 2014). The purpose of this paper is to identify appropriate methods of geotechnical soil assessment to establish engineering parameters for geotechnical design. Geotechnical soil parameters should be based on the results of a complete geotechnical investigation, which includes in.situ field.testing and/or a laboratory.testing program, used separately or in combination. Such investigation is carried out in order to avert structural failures, as these failures could lead to disasters which pose serious threats to public safety. The ultimate goal of site investigation is to have an appreciable understanding of the behavior of the soil which will bear load to be transmitted by the proposed structure. In the last decade, the involvement of geophysics and geotechnical methods in civil engineering has become a promising approach (Adepelumi et al., 2009; Al Omosh et al., 2008; Schoor, 2002; Adepelumi and Olorunfemi, 2000). Geotechnical measurements may greatly improve the quality of construction in civil engineering as it will focus on the behavior and performance of soils and rocks in the design and construction of civil engineering structures (Oyedele et al., 2009). (< ’ Gandhinagar lies on 72°37’30’’ E to 72°41’15’’ E longitude and 23°09’45’’ N to 23°15’00’’ latitude and lies on banks of the Sabarmati River. It has an area of 649 km², and a population of 1,334,455 of which 35.02% were urban (2001 census). The district includes Gandhinagar with three Suburbs . Chandkheda, Motera, and Adalaj. The four tehsils are . Gandhinagar, Kalol INA, Dahegam and Mansa . and 216 villages. Gandhinagar district is bounded by the districts of Sabarkantha and Aravalli to the northeast, Kheda to the southeast, Ahmedabad to the southwest, and Mehsana to the northwest. (R.K.Verma, 2014). Gandhinagar district forms a part of Gujarat plain and is sub.divided into two sub micro.regions namely Sabarmati plain and Khari plain on the basis of Physiography, climate, geology, soils and natural vegetation (Pancholi et al., 2017).Physiographically the Sabarmati plain is an alluvial plain claimed by the River Sabarmati which flows in this region from north to south direction and divided the district into
