LASERS-THE BRIGHT LIGHT THAT CONSTRUCTION HAS BARELY NOTICED

CURRENT AND FUTURE APPLICATIONS ARE REVIEWED FOR LASERS IN CONSTRUCTION. TYPICAL LASER DESIGNED FOR CONSTRUCTION HAS AN OUTPUT OF 0.002 WATTS. IT IS USUALLY A GAS LASER THAT PRODUCES AN INVISIBLE (IN DAYLIGHT) RED BEAM ABOUT 1/8 IN. IN DIAMETER. THE CONSTRUCTION LASER SHOULD BE ACCURATE WITHIN 1/4 IN. IN 1,000 FT. ITS OPERATING RANGE IS ABOUT 3,000 FT. THE UNIT WEIGHTS ABOUT 15 OR 20 LB. AND IS POWERED BY EITHER 110-VOLT AC OR AN AUTOMOBILE BATTERY. IT WILL COST FROM $2,000 TO $4,000. AMONG SOME OF THE THINGS THAT A LASER CAN DO, SOME TRIED, SOME NOT, ARE: ALIGN RAILROAD TRACKS AND ELEVATOR RAILS, KEEP A PILE DRIVER OR DREDGE ON COURSE, AND GUIDE A BULLDOZER, TUNNELING MACHINE, ROAD GRADER, TRENCHER, SCRAPER, BRICKLAYING MACHINE, OR A PIPE PLOW. /AUTHOR/
