A FASTER AND MORE ACCURATE BUILDING SURVEY WITH LASER EQUIPMENT

CONSTRUCTION LASERS WHICH ARE PROTECTED AGAINST IMPACT, DUST, FLUCTUATIONS OF TEMPERATURE FROM MINUS 30 TO PLUS 65 DEGREES C, ATMOSPHERIC MOISTURE AND PRESSURE UP TO 2.5 ATMOSPHERES HAVE BEEN AVAILABLE FOR TWO YEARS IN GERMANY. THEY ARE USED TO ADVANTAGE IN TUNNEL CONSTRUCTION, CANAL AND PIPE CONSTRUCTION, IN PIPE PUSHING AND FILL CONSTRUCTION, AND ALSO FOR THE AUTOMATIC CONTROL OF CONSTRUCTION EQUIPMENT. THE PARTICULAR ADVANTAGES OF THE METHOD ARE ITS ACCURACY AND SIMPLICITY. CONSTRUCTION LASERS ARE NOT DANGEROUS AT OUTPUTS AROUND 0.005 W. BECAUSE OF THE BRIGHTNESS OF THE BEAM - A MULTIPLE OF THE BRIGHTNESS OF THE SUN-THE HEIGHT OF THE BEAM IS KEPT IF POSSIBLE ABOVE HEAD LEVEL OR BELOW KNEE LEVEL. /TRRL/
