Subsurface Imaging, Inc. was hired by Morrow Meadows Corporation to inspect nearly 100 areas that would later be core drilled. Morrow Meadows owns and operates their own core drilling truck and operator. However and as one can imagine, Morrow Meadow core rig operator is incredibly busy. When the Morrow Meadows Foreman for this project heard that Subsurface Imaging now offers coring as a service, he jumped at the opportunity to have us both inspect and core drill each location. He immediately saw the benefits of one company performing both services; time savings equals money saving.

Because other trades were working in this area, we could not start work until they moved out, which was on a Wednesday. However, we had to be completely finished by that Sunday. Normally, this would have been a one, maybe a two man operation. This particular job required three people. We were working directly above the stadium seating on a rolling scaffold. We needed to push this scaffold to each location, navigating the four legs through the aisles of the seats,

not an easy task. Once the scaffold was locked into place, we needed to climb back up to the platform, set the drilling rig and core the 2” x 16” hole. This needed to be done 88 times as we traversed around the entire stadium.

Not all beams are created equal – As we soon discovered, while the beams looked the same on the outside, they were not created equally on the inside. Our client needed to re-adjust where the holes would be drilled roughly one third of the way into the coring operation. Normally, this would have meant stopping the coring company, making a call to the inspection company, praying there’s an availability and waiting for them to arrive. Not so if you’re both a coring company AND an inspection company all wrapped into one. We simply brought out our radar unit and checked alternate areas. This saved our client time and money once again. Instead of calling the inspection company back out to recheck areas, the “coring company” simply switched hats and transformed into the “inspection company”. We happily completed both the radar and core drilling operations on Saturday, one full day ahead of schedule. Needless to say, another happy customer.

S.I.I. goes Ballistic

Posted on January 29, 2013

San Onofre Nuclear Generating Station is currently upgrading part of their security by adding several concrete and steel reinforced ballistics walls to their security perimeter.

To accomplish the utility locating duties our company has been hired to perform. Our technician is using a 400 MHz ground penetrating radar antenna, as well as passive and field induced locating devices.

Phase I of our project: Locate and map out all utilities within a trench line that is approximately 10 feet wide by 4500 feet in length to a depth of 4 feet.

Phase II: Locate and map out all utilities within a trench line that is approximately 40 feet wide by 1 mile in length to a depth of 4 feet.

Mojave Air and Space Port, Virgin Galactic, The Spaceship Company
Posted on January 29, 2013

We’re very excited to welcome Virgin Galactic & The Spaceship Company as our newest clients. We recently worked at their Mojave rocket test facility located at the Mojave Air & Spaceport. Our technician was tasked with the duty of locating and mapping all of the rebar within 2 concrete pads. These pads will be used in the near future to test the rocket motors which will be utilized on Spaceship Two.

Spaceship Two is the predecessor to the historic Spaceship One completed the first manned spaceflight by a private company in 2004.

Our technician used Ground Penetrating Radar, (G.P.R.), to locate each piece of rebar within the concrete pad. He was also asked by our client to determine the depth of each piece of rebar and the concrete thickness. This was an standard task to accomplish and one well suited for our radar system.

All of us at Subsurface Imaging, Inc. are very proud to unveil our new website. While we loved and were proud of our old site, it became the one thing we never wanted it to become, dated and stale. Unfortunately, the way the old site was constructed, it did not allow for changes to be made easily and thus a new website was created.

One of our primary goals with this new website was the ability to communicate in near real time with our clients. We found it increasingly necessary to inform our clients of the changes taking place within our company in ways our old, stagnate website could never do.

One area of the new website that will constantly be changing is our “blog” section. Look for new articles in this area weekly. The blog topics will range from special announcements or new services we plan to offer, to new techniques being used within our industry to unusual jobs and job sites we’re currently working on. We’re hoping this will be a fun way we can inform, educate and communicate with our clientele.


We sincerely hope you and your family have a happy and prosperous 2013.
