These surveys are required to depict the infrastructure, contours and natural features on a particular site/sites. They are generally used by planners and engineers in their designs for various types of developments. These surveys can be as small as a simple site survey for small building projects (houses, schools clinics etc) or at a much larger scale, for road upgrading, water reticulation projects, township development etc. It is not unusual for the company to be appointed to undertake large scale topographical surveys, in excess of 100 hectares. NPM has completed the survey of a number of large clusters of schools and clinics in the province, usually within very tight timeframes, with delivery of up to 15 school or clinic sites completed per week. NPM has surveyed in excess of 650 schools in the Eastern Cape.
