Our experts use US Military TRADOC PAM 385-1 guidelines to inspect, test, repair, modify, update, and rebuild existing O-Courses for JROTC & ROTC programs and some of the most legendary US Military Courses nationwide.

So many of the formerly prestigious courses located at US Military nationwide have fallen into a state of disrepair where they can no longer be used for training and PT and become a sad eyesore. Obstacle Builders can completely demo, repair, replace, or modify these courses extensively to bring them up-to-date and make them a vital part of our military training regimen!

Harsh weather takes a toll on courses all over the nation - we've built and repaired courses in freezing cold Alaska and the hottest climates in Arizona and Texas to the southeast coast where hot, humid, salty conditions can deteriorate elements quickly. We replace ropes, cargo nets, safety nets and other elements that have become worn and unsafe with the newest, best materials available.

Sometimes an obstacle course is just too far gone for even experts like us to save. We can dismantle, remove, regrade, and install a brand new course with updated elements to serve your needs - military, first responders, or civilian clients all across the USA.
Obstacle Builders' (Standard Maintenance & Limited Warranty)
The additional level of care and ongoing maintenance to keep an obstacle course safe while also withstanding weathering as long as possible can be a difficult task to require of your existing grounds crew / maintenance staff. TRI PHX LLC offers a bi-annual Expert Maintenance Program to assist your staff in protecting your investment and keeping the course safe for use. Please note: While our Expert Maintenance Program consists of in-depth inspection and maintenance of your course, daily visual inspections and ongoing maintenance are still required by your staff as listed in your contract under “Element Maintenance”.
One Year Expert Maintenance Program Includes
Twice-yearly inspection and maintenance of your entire Obstacle Course including:
Inspection: Comprehensive checklist of all elements in accordance with US Military TRADOC Pamphlet 385-1 starting at page 132, Table C1. PLEASE NOTE: TRADOC PAM 385-1 checklist will be followed as a guideline, however the obstacles outlined are significantly different in size, shape, and construction than those that are installed for your program.
All wooden elements will be inspected for wear & tear, water damage, dry or moisture-related rotting, warping, splinters, splitting, or any excessive damage that could compromise structural integrity or harm cadets. All hardware will be inspected for structural integrity and re-tightened, any damaged screws will be replaced or augmented with additional hardware if needed.
Sanding & Re-Sealing: Obstacle Builders will sand and seal/re-seal all surfaces displaying any excessive damage, splitting, rough surfaces, or splinters.
Please Note that all natural wooden elements will splinter or become rough from repeated usage and no amount of expert maintenance can prevent all natural wear & tear or splinters. Instructors or school maintenance staff must inspect wooden surfaces weekly for any potential rough spots that should be sanded or re-sealed. This is part of standard Element Maintenance as outlined in your O-Course Contract.
Sealing of wooden surfaces consists of multiple coats of Thompson’s Water Seal or similar and excessively worn surfaces or areas with high amounts of body contact will receive multiple coats of a Premium Deck Resurfacer such as DeckOver or similar. Cracks larger than ¼” that do not pose any structural integrity issues will be filled with a high-strength expanding flexible waterproof sealer before sealing.
All sealant products are included with our Expert Maintenance Program
Hardware Inspection and Tightening: All hardware will be inspected for structural integrity and re-tightened, any damaged screws will be replaced or augmented with additional hardware if needed.
