What is the primary function of construction lasers in project control?

The primary function of construction lasers in project control is to control line and grade during construction. These lasers use a focused beam of light to establish accurate horizontal or vertical reference points across the construction site. This precision is crucial for various tasks such as leveling foundations, aligning walls, and setting elevations.

By projecting a level plane over a designated area, construction lasers allow surveyors and contractors to ensure that structures are built according to design specifications. This capability helps to minimize errors and rework, leading to increased efficiency and cost-effectiveness in construction projects. The use of lasers provides a visual reference that is easy to follow, making it an essential tool for achieving the desired level and alignment in various construction activities.
