Our Services


We firmly believe that only companies that concentrate their work in certain areas can provide truly exceptional work. Since we would never offer our customers anything less, we specialize in the following core competencies:

Drone Surveys!  We have a DJI Phantom 4 RTK with a D-RTK 2 Mobile Station to provide you with centimeter level topographic mapping.  This means we can capture most of your site with the drone, and supplement it with some on-the-ground data like the building foundation.  We can also capture adjacent grades without entering onto the neighbor’s property!

Underground Pipeline Survey

How did Eric save a contractor and client over 100,000 when he was 24? 


Back in 1998 Eric was working on the layout of the Bacara Resort and Spa in Gaviota, CA.  The  pipeline contractor was drilling a horizontal pipeline under the 101 freeway (about 330') ran into extra hard rock half-way through the drilling.  The pipe began to curve to the right due to the hardness of the rock. 


In order to avoid other existing utilities, and reach their target area, the contractor decided to drill from the other side of the freeway but needed to know where to match up in the middle. 


This effort would require a team effort of surveyors, engineers, welders, and the drillers.  Eric, who had only been out on this project a few times, was replacing the normal crew chief that day and was tasked with finding a way to map the pipeline.  The OSHA representative and the owner rep. decided against an entry to locate the 24" pipeline. 


A lot was on the line, time, money, new permits...... it required some out of the box thinking and a willingness to take a risk.  Eric laid out control to get in position. He spotted the right area with his compass mirror, and plumb bob.  The contractor built a platform only a few inches off the ground, perfect for seeing into the darkness of the pipeline. 


Eric then had the contractor build  160' of 4" PVC irrigation lines with a prism set on the end.  Together we were able to survey the entire length of the underground pipeline and stake out an alignment on the other side in a matter of a few hours.  No re-design, no re-engineering, and the project continued. 


It's this type of problem solving and "out-of-the-box" thinking that separates Eric from the crowd.
