Construction surveying is the process of measuring and mapping land to guide the construction of buildings, roads, and other structures. It involves determining the precise location, elevation, and dimensions of a site, ensuring that construction projects are built accurately according to design plans. Surveyors use various tools and techniques, such as theodolites, total stations, and GPS, to collect data. This information helps architects and engineers create blueprints and ensures that the construction adheres to local regulations and standards. Proper surveying is essential for the safety and stability of any construction project.
