Construction layout or construction surveying is the process of laying out markers to indicate where buildings, roads, or other infrastructure are to be constructed.
An initial site survey is used to assess the existing conditions of the work site including the topography and any key features. In the case of buildings, lot corners are then staked out around the edges of the property boundary. Reference points and gridlines are also staked out to mark the areas where work is to be completed.
In addition, Challenger will return as required to verify locations align to the initial site survey, monitor controls or conduct deformation monitoring.
Working with our clients, Challenger uses various technologies and equipment to carry out initial measurements as well as monitoring site changes over time. Total stations, levels, GPS surveys, and 3D laser scanners are deployed regularly for construction surveying to measure the distances, elevation and angles on the ground. Upon completion of the project, Challenger would also verify with an as-built survey to confirm any deviations from initial engineering plans.
