The American Institute of Architects believes building-related waste makes up anywhere from 25% to 40% of America’s solid-waste stream. With construction spending in the U.S. totaling $1.13 trillion this year, those losses add up to more than $160 billion in waste in America.
Developing methods to more accurately calculate quantities on building or fill materials needed, or soil and rock to excavate will lower costs and reduce waste.
Construction companies are turning to unmanned drones for surveying. Drones are cheaper to fly than manned aircraft and work faster than human surveyors. They can be used to collect data more frequently than either, letting construction workers track a site’s progress with a degree of accuracy previously unknown in the industry.
With the right computing tools, particularly building information modeling software, builders can turn sensor data into 3D structural models, topographical maps, and volumetric measurements. The data can be used formore precise calculating and monitoring of stockpiles of costly resources like sand and gravel.
