Reasons to Choose TOPS to Do The Data



No need to sweat the details. We comb through the plans, finding and fixing problems electronically before they become dirt mistakes. From school sites to the runway expansion at Los Angeles International Airport, we know the details of data.


Do you like red property lines instead of blue? How about overbuilds on pads, streets to subgrade, and 15 foot storm offsets, we build your data the way you like it… every time.


We don’t sell equipment, software, or supplies. All we do is perform the best takeoffs, and build the best data in the business. We may be one trick ponies, but it’s a great trick.


Need a rough grade file to start while plans are being finished? Want to combine the offsites with the current job? How about curb offset points for layout? We have the experience and ability to make all your jobs more profitable and more efficient.

Nobody has more experience than we do. We complete over 450 jobs per year ranging from parking lots to super highways. We prepare more data in a week than the largest contractors build in a year.


The advantage of TOPS accuracy, turnaround time, and consistency make us your best choice. The reason to use GPS is to move dirt one time, great data insures this.
