Custom Services: Special Effects and High Angle Engineering  

Chuck Norris – Walker Texas Ranger was doing a river crossing where a young boy slips from the wagon into the river and is rescued. Location was scouted in the spring, but the fall is when water levels are down. We were called in to engineer a water level adjustment device (WLAD) to raise the level of the river from a few feet deep, to about eight feet deep, or enough to rescue someone. Norris can be seen talking with the director.  The WLAD is allowing the river to flow, during the shoot, we added sections, and the WLAD was almost totally under water.

Rescue 9-1-1 hosted by William Shatner. We were called in to assist with safety and the technical end of a 30 foot fall from the cliffs of Bridal Veil Falls.  An reenacted an accident where a boy fell from the cliffs while his family watched. Getting the Stunt Professional in place on the cliff, safety, and building a platform for the stunt person to land on, and to engineering a dummy “sliding rolling” fall was some of the details.


Although this may appear risky we engineered a system to maintain a low risk operation for the TV Commercial

In this picture you can see the safety lines. The actors wore a harness under their clothes, and we had a rescue system ready, just in case we had to pull them off the line. That was the easy part. Putting this log across the gorge was the tricky part.  We used

I’m going over some last minute details with Donny Osmond. I engineered a special supportive safety harness for his Grand Entry into the Stadium of Fire 4th of July Celebration. He sang to 60,000 +/- a few there in the LaVell Edwards Stadium athletic stadium in Provo, Utah, on the campus of Brigham Young University.   I am wearing black clothing so I don’t stand out.  I had to ride on the opposite site of the helicopter for technical support, and as a counter weight (making sure the Center or gravity was maintained).

After summitting in the Tetons, Hansen’s yells (while dressed as a Monk) “NOW THAT”S A PIZZA!!!” Repeatedly, until the camera man got so sick the helicopter landed to let him expel his breakfast.

Rigging the cliffside for the actors to do their thing. We had to engineer a camera platform just right, so they could get the POV they needed. The of the platform corner can be seen in the bottom right

The camera platform. Engineering these and installing them was tricky. Then making the area so that there was no trace or damage to the area was the second trick. A great team of people helped to made it possible, Thanks Guys!!!

Demonstrating a safety system we engineered and installed for the Vivint Smart Home Arena, home to the Jazz. Riggers must access many different places in the arena depending on the various shows that are hosted here..

Demonstrating the fall arrest system we engineered and installed

A rappelling tower I designed and operated with my team of High Angle Professionals.



Working on the underside of this BOR Wedge Dam. Putting scaffolding up and taking it down for every section would be time consuming not to mention dangerous. We engineered a system so the work could be done while hanging on a rope.


Drilling out / cleaning out the drain holes between layers in the dam. The blue line is the work line and the yellow is a secondary safety line.

Our team part of a BOR project to engineer and install a rock fall mitigation system. This is cable netting system we installed, after we scaled the face. The netting across this face was to protect the a large cement gravity dam, roadway and a boat ramp, and of course, the public. (see story below)  The system should last 20 years.

Installing 30 foot long x 1.5″ diameter bolts to prevent boulders from coming down at an inopportune moment.

15 or 20 years earlier another mitigation system was installed, but time did its thing, and as can be seen it was time for something different. This show a bolt, similar to the ones we installed on other flakes, and boulders, to hold them in place. Some were too unstable, in the video below we bring down a 350 ton flake/boulder under controlled conditions.



The old system had to be removed (in the picture) along with a plan for dealing with the rock fall. We used High Angle Work Professional rappelling down the face with a reflective target so we could use a Total Station to establish a profile of the face. From there we use computer generated rock fall simulation to make sure we needed protection, and to know where and how much to install.

This is one of our computer generated rockfall profiles. After thousands of simulated rocks were dropped down the face, we were able to locate, and design the height of the barrier to protect the road way, parking area, and other structures.



Scaling the face (Manually bringing the loose rocks and boulders down) this is M38, too loose to bolt, so we used some special equipment to bring it down under controlled conditions One of the guys joking around crawled under it. We all got a chuckle out of it.


Natural Rockfall is a more bigger problem then is commonly known. People who work in the canyons and mountains see it rather frequently

Some of our team working high on the face installing sections of cable rockfall netting.

Some of our High Angle Work Professional attaching another section of cable netting on our transport line, to position it on the face hundreds of feet up. This was installed over special rock fall “double twist’ which looks like chain link but does not fall apart if a section is damaged.
