BUSINESS SPOTLIGHT: Rocky Mountain Construction

Updated: Apr 21, 2020

Rocky Mountain Construction began in 2001, with a staff of 10 employees who repaired traditional wood coaster tracks in Fred Grubb's garage in Athol, Idaho.


After several years of designing and building water parks, erecting and repairing other manufacturers’ coasters, and constructing steel buildings, Grubbs knew that there had to be a better track system that would not require the constant repair/maintenance of the traditional wood tracks.


Grubbs met with renowned coaster engineer, Alan Schilke, and in 2008 the all-steel IBox track was born.


Six Flags gave RMC their first big break, with a contract to overhaul an existing wooden coaster, The Texas Giant.


Among current projects, is the highly-anticipated overhaul of the famed Iron Gwazi roller coaster at Tampa Bay's Busch Gardens.


Set to be ready this spring, the reborn Iron Gwazi will feature RMC’s patented IBox steel track, but still retain much of the original coaster’s wooden structure, which opened in 1999 and closed in 2015. The redesigned layout will make the Gwazi considerably taller and faster. With a 206-foot drop and a top speed of 76 mph, it will be RMC’s tallest and fastest hybrid coaster yet and will introduce three flip-flopping inversions into the mix.
