Construction Acronyms – What do they mean?

The Construction Industry loves its Acronyms. An acronym is simply a word or name formed as an abbreviation from the initial components of a phrase or a word, usually individual letters, as in NATO (North Atlantic Treaty Organization) or SCUBA (Self-Contained Underwater Breathing Apparatus) and LASER (Light Amplification by Stimulated Emission of Radiation). Another unusual one is TASER. This actually stands for “Thomas A Swift Electric Rifle”.
