Surveying
Placing the target at deck level eliminates errors from out-of-plumb rod work.
Rather than rolling out a set of plans on a concrete deck in the wind and rain, and trying to find everything you need, you simply set the instrument up and tell it what points you want to layout.
"14 seconds, and go out 47 feet." You can then take a measurement to someone at that approximate location and the instrument will indicate you're close but you need to go to the right two inches and you need to come closer to the instrument by four inches.
Rather than rolling out a set of plans on a concrete deck in the wind and rain, and trying to find everything you need, you simply set the instrument up and tell it what points you want to layout and the instrument tells you where to go and how far to go to do it.
So, when and how can you use these instruments? Smith comments, "Masonry applications for survey products would be associated with checking layout and making sure forms are poured according to blueprints and that the foundations are level before starting construction. This will save the mason from any rework and other costs associated with incorrectly poured foundations, for example."
The key for a mason contractor looking at buying or renting a surveying solution is to select the right tool for their application and to invest in a high-quality, accurate and durable solution that will withstand jobsite conditions. Applications Surveying continued on page 37
