Geological survey is the first step towards the completion of a building and is considered the most important phase as it identifies the feasibility of an area for construction and determines how to set the foundations and preventive measurements for the building. According to Sadhi (2012), one third of construction projects are delayed and half of excessive bidding costs for road projects are due to inadequate geological investigations or poor data interpretation. According to Ferrer Geological Consulting (nd), the geological survey is mandatory to ensure an adequate design that takes into account maximum safety and the optimal economic benefits to be obtained and saving on the geological survey budget has proven to be a false economy. As illustrated in Figure 1, the geological survey process involves conducting a desk study and reconnaissance of the proposed site, conducting a preliminary geological survey, preparing a detailed geological survey plan, conducting a Detailed geological survey and preparation of a soil exploration report. Desk study and site reconnaissance are conducted as the first step of the geological investigation. In general, all available maps and documents relating to a site should be examined (Kehew, 1995). Subsequently, Jackson (1968) indicated that with all the information on the type of project to be carried out, the main geological and environmental risks at the optional sites and possible site visits are identified. Using information from topographic and geological maps, aerial and ground photographs and any previous survey reports in the vicinity, the accessibility of the site and the nature of drainage in and from it is identified, indication of subsoil stratification... half of paper . .....14(3), 62-64.Pye, K.
