Machine control, often referred to as machine guidance or machine control systems, involves the use of advanced technology and equipment to guide and control the operation of construction machinery. These systems integrate on-board sensors, GPS, GNSS (Global Navigation Satellite System), and sometimes optical instruments with digital design data, allowing machines to precisely position themselves and conduct tasks in real-time relative to the design. Machine control offers numerous advantages in construction, including: Increased Accuracy: Machine control systems provide real-time guidance to operators, allowing them to execute work to exact specifications. This can reduce or eliminate the need for manual staking or marking on the construction site. Efficiency and Productivity: Operators can achieve design grades and alignments more quickly, reducing the number of passes required and saving time. This can lead to a faster project completion time. Material Savings: By reducing over-excavation and minimizing material wastage, machine control systems can result in significant savings in terms of materials. Reduced Rework: The precision of machine control systems often means fewer errors and, therefore, less rework. Real-time Feedback: Operators receive immediate feedback on their progress, allowing for on-the-spot adjustments and decisions. Safety: By automating certain tasks and reducing the need for workers to be present in active machine areas for tasks like staking, the risk of accidents can be diminished.
