tle surveying on your own.
ONTRACTORS ARE WELL ADVISED to hire professionals in the specialized fields that are required to establish a job site and construct a building. But sometimes, a little do-it-yourself work to augment those professionals not only gives you a better sense of what is going on, it gives you a greater confidence and legal backing-during the job itself.
One area that many mason contractors overlook is in establishing the actual versus planned job site layout. Did the previous trades, such as grading and foundation, hit their marks? When you start to lay your first courses, will they be exactly where the plans call for them to be? Taking time before you start work to survey the job site and lay down your own coordinates could save you from problems later. If nothing else, those efforts will give you better peace of mind, letting you know where things are as well as where they are supposed to be according to plans.
Over the past decade, tools that were designed for and used by surveyors have migrated into the construction market. It used to be that only construction surveyors and engineers used these tools, but as the instrumentation has become easier to use, these tools have become appropriate for contractors to use. According to Lawrence Smith, business manager at Trimble's Construction Instruments Division, Sunnyvale, Calif., these new instruments "allow better productivity and lower cost. Trimble alone provides a wide portfolio of survey-type products and solutions for building construction and site preparation applications"
Using a total station like this Nikon (main photo) or Trimble laser unit (lower inset) makes surveying easier for non-professional surveyors, such as mason contractors. The Voice of the Mason Contractor
