A topographical survey is undertaken by a land surveyor, using specialist surveying equipment such as Total Station (an instrument which measures points relative to the instrument location), GPS or 3D laser scanners. Using these instruments, a Land Surveyor can measure the location of all features with high precision. After conducting a topographical survey on a site, the land surveyors will process the data collected to form a map of the features measured during the survey. A topographical survey is a crucial component of any successful construction or engineering project. Position and height data recorded from the survey can help prevent costly problems such as building in unsuitable areas. Our Bolton topographical surveys will leave a number of fixed reference markers, such as nails in concrete which can later be utilised when setting out a new design so that elements such as foundations, brickwork, new trees and more, are in place in the correct positions.
