Usually powered by a 12-v battery, lasers produce a pencil- thin stringline of light that workers use as a reference for leveling, plumbing, aligning, and grading. There are two types of lasers in construction: the sewer or transit laser delivers one stationary beam used at one location; and the rotating laser which spins the beam 360 deg., providing a plane of light that can be used anywhere on the site. The major tasks for which lasers are used and the type that best fits the job are tabulated. The basic capabilities of the laser tool are discussed. It is noted that the savings related to laser use varies with the different procedures used on different types of work and on the size of the job. For aligning and grading pipe, contractors report 10 to 30% more pipe laid per day using lasers. Savings related to leveling jobs are also discussed.
