Automation in Construction

  2. 2. O Labor efficiency is alarmingly low O Skilled workforce is vanishing O Work quality is low O Control of the construction site is difficult O Accident rate at construction sites is high O Waste and trims are high (3 To 7 tons per average home; 40% of all materials used worldwide are for construction) O Low income housing and emergency shelters are critical O Construction is the largest sector of almost all economies O All other products are fabricated automatically – construction is still largely a manual task Labor productivity comparison for non-farm industries and construction industry Construction Productivity index Non-farm productivity index

  8. 8. A Machine Guidance system will be considered to be one that uses automation to provide the equipment operator a visual indicator of the position of the cutting edge (blade, bucket, screed, etc) relative to the design surface being constructed.
  9. 9. Some advantages of guidance machines at the construction site: O No stakes required O No grade checker required O Records data for quality control O Records data for volume computation O Data could be transmitted to engineer, inspector, or surveyor for “real time” checks
  10. 10. Types of Guidance Systems O Stakes O String Lines O Sonic Sensors O Lasers O GPS O Total Stations O GPS w/Lasers
  11. 11. O GPS provides near exact position of vehicle in “real time” O Cab mounted display indicates position of machine relative to design anywhere on the surface O Equipment operator controls cutting edge Guidance By GPS
  12. 12. Laser augmented GPS systems delivers a few millimeters of vertical accuracy using conventional lasers capable of working on an inclined plane
  13. 13. Total Systems O Started in the early 1990’s with robotic motorized total stations that could track a prism mounted on a machine  Could position the prism to high accuracy - equivalent to string lines and lasers
  14. 14. 14 O Information from the prism position could be sent to the machine, which would adjust the hydraulics accordingly.
  15. 15. A Machine Control system will be one where the cutting edge of the equipment is fully controlled by automation. The system is connected to and controls the hydraulics while the operator simply drives the equipment and manages the automation.
