Arx Engineering is a structural design firm specializing in residential and commercial buildings.  The word “Arx” (pronounced “Arks”) is Latin for “fortress” or “stronghold.”  The company was started in 2009 by Ryan Briggs, in the middle of the not-so-Great Recession, and has grown ever since.

Our business is designing structures, but our purpose is delighting clients with our service.  Delighted clients come back, and spread the word.   We love to help people.  Hearing people say “thank you” and knowing that we truly helped them means a lot.





Principal Engineer

Ryan Briggs, PE is Arx Engineering’s principal and founder.  Ryan holds B.S. and M.S. degrees in civil engineering (structural emphasis) from Brigham Young University.  His masters thesis was titled “A Genetic Algorithm That Finds All Optimum Topologies of Skeletal Structures” – sounds like fun, eh?  (If you ever have trouble falling asleep, ask him for a copy!)  He has been engineering since 2004, and is a licensed civil engineer in the states indicated below.  He has also served as a member of the structural committee for the Southern Nevada Building Official’s code amendment/adoption process for the International Building Code (IBC). 

Ryan’s office nickname is “Stark” because he is the head honcho, and a handsome, rugged billionaire (in his dreams).  He believes one of his most important responsibilities is to make his employees laugh and enjoy work as much as humanly (and humanely) possible.  In his free time, Ryan likes to do manly things, like punching his punching bag and writing poetry.  See Ryan’s LinkedIn profile for more information.



Office Manager

Rebecca is Arx Engineering’s Office Manager.  She handles the books and keeps the office running smoothly.  Rebecca’s office nickname is “Pepper” because she handles all the logistics (well,12% of them), and she is married to the big boss. She enjoys spending time with her family, as well as pursuing personal fitness and nutrition goals, and is good at singing and cooking, and also painting (although she says she hates it).




Drafter/Assistant Designer

Christian has been a CAD Technician at Arx Engineering since 2014. He works attentively with a focus on increasing work efficiency. He mainly works on drawings and calculations for wood framed residential construction. Additionally, he works on improving the company’s CAD workflow. Christian’s office nickname is “Jarvis” because of his computer troubleshooting expertise, AutoCAD dynamic block knowledge, and subtle sarcasm. He has made many dynamic blocks in AutoCAD to increase the workflow speed of all the employees.
Christian is currently studying Mechanical Engineering. In his spare time, Christian enjoys 3D printing, model building, and tinkering with electronics.


Drafter/Assistant Designer

Sariah is a newer CAD Technician at Arx Engineering. She is intelligent and optimistic. She works mainly on garages, casitas, and patio covers. Additionally, she prepares the agenda and keeps minutes at our weekly internal meetings.  Her office nickname is “Shuri” because of her ability to prepare the necessities for the company, while keeping her team mates on their toes (which may include the occasional prank).
In her spare time, Sariah reads, writes, plays many musical instruments, and does anything and everything crafty or inventive. 


Drafter/Assistant Designer

Benjamin is Arx’s newest CAD Technician.  He excels at understanding the mathematical concepts behind drafting and engineering.  He mainly works on one-story additions and remodels.  He is the office’s paperless expert, scanning and uploading documents.  Benjamin’s office nickname is ”Dr. Strange” because he manages meeting times and reminders, and keeps everything in balance.

Benjamin once created a miniature model of an entire house’s framing using Popsicle sticks. In his spare time, Benjamin enjoys 3D printing/ modelling and biking. 


I first contacted Ryan with Arx Engineering in 2012 from a referral given to be by a colleague….Since then I have engaged Arx Engineering on several Design Build projects and would recommend them to anyone in the industry. Ryan is easy to work with and always comes through when you need him. I look forward to working with Arx on many more projects in the future.

I have personally used the services of Arx engineering on numerous occasions.  In every instance I have found them to be extremely knowledgeable, professional, and sensitive to the time and budget constraints I’ve been under.  The work they’ve done for me has always met the need, and has always considered the cost impact.  The owner, Ryan, has always gotten back to me in a timely manner when I had questions.
