Engineering is the application of scientific principles to design and build structures, machines, and systems that solve problems and improve lives. Engineers work in various fields, including civil, mechanical, electrical, and software engineering, focusing on creating efficient and safe solutions. Surveying involves measuring and mapping land to determine property boundaries and topography. Surveyors use tools like theodolites and GPS to collect data, which is essential for construction projects, land development, and legal documentation. Together, engineering and surveying ensure that projects are accurately planned and executed, contributing to infrastructure and community development.
