Introduction to Laser Tools

Construction lasers are used as an accurate level reference during any layout

process. Applications include installing ceiling tiles and levelling floors, performing basic surveys,
and even construction site grading.

What is a construction laser?

Construction lasers can be used in a variety of jobs that require layout work and where an accu-
rate level reference is needed. This can include any of the following:

 Installing ceiling tiles.

 Installing chair railings in a dining room.

 Installing power conduits and receptacles for a home that‘s under construction.

 A construction laser can also be used to hang pictures across a living room wall or to install a
sewer pipe. It can even be used to come up with a grading plan for a new building.

How do laser levels work?

Construction laser levels use a focused beam of light that has been amplified from a solid-state
device (called a diode). The light-emitting diodes (LED‘s) can be found in many different devices,
and the same technology is used in a construction laser. It projects a beam of light that can be

used as a visual straight-line reference, but the size of the beam depends on the size of the di-

ode. In this application, a smaller beam is better because it‘s more precise. With a wider beam,
the actual level point can be anywhere within the width of the beam.

How accurate are laser levels?

Construction lasers can give you a point of line that you can use as a level or square reference

for most job sites, and they‘re usually accurate up to 250 feet. Contractors once needed to use a
bubble vial (also called a ―water level‖) to make accurate level or square measurements. Now,
