With the skip loader and GPS system, Shane Thomas Construction is well equipped to handle smaller jobs. "On most of the small parking lots we do that are under 100,000 sq. ft., I will not even bring a blade in for it," says Thomas. A dozer may be used to rough it in, but then the box scraper is used for the finish work.

The accuracy of the box blade with the GPS system has proven more than adequate for Shane Thomas Construction. It is within half of a tenth of a foot. "That is within any tolerance that I have seen," says Thomas. It also saves valuable time during finish grading since you're not moving the material twice. "Your finish time is cut in half."

The price of entry for 3D systems can be intimidating. "The initial investment is pretty high," Thomas admits.

But you have to take into account the grade setter you may be currently employing. If this person isn't bogged down with staking, he or she can be utilized elsewhere. "You can free up a grade setter to do other tasks," says Thomas. "I have one there, usually running other equipment. You eliminate the staking."

It's also not necessary to immediately run out and purchase a system. "You can rent the systems, too. That's what I did," recalls Thomas. "I rented it a bunch of times, and [Topcon] gave me a good deal on the one that I am running."
