Rocky Mountain Construction
Rocky Mountain Construction (RMC) is an American roller coaster manufacturing and construction company based in Hayden, Idaho, United States. It is best known for its I-Box track and Topper Track for wooden roller coasters. Founded by Fred Grubb and Suanne Dedmon in 2001, it has built over 20 roller coasters. In 2023, it merged with amusement ride manufacturer Larson International.
In 2001, Rocky Mountain Construction was established by Fred Grubb and Suanne Dedmon. Fred Grubb previously had experience in the construction industry having worked on custom homes and zoo exhibits. The company has worked on several projects including the construction of roller coasters, water parks, steel buildings, miniature golf courses and go kart tracks.
In 2009 Alan Schilke of Ride Centerline began providing design and engineering work for Rocky Mountain Construction. He previously worked with Arrow Dynamics (later S&S Worldwide) to design Tennessee Tornado, Road Runner Express, and X. Working with Rocky Mountain Construction, Schilke and Grubb designed the I-Box track for wooden roller coasters. The first installation of this track technology debuted on New Texas Giant at Six Flags Over Texas in 2011.
In late 2011, Schilke announced that the company would be working on two projects throughout 2012 which would both open in 2013. These were later revealed to be an I-Box retrack of The Rattler at Six Flags Fiesta Texas and a new roller coaster designed from scratch at Silver Dollar City named Outlaw Run. The track technology used for Outlaw Run, which allows a square beam of wood to be twisted, took 4 years to develop. It allows Rocky Mountain Construction to design layouts with maneuvers that are not traditionally possible with wooden roller coasters such as heartline rolls. Grubb has stated the technology could be used for new elements in the future. Some new elements were realized with the announcement of Goliath at Six Flags Great America. The ride features a dive loop and a zero-g stall. The ride opened in June 2014.
In 2013, Rocky Mountain Construction signed a deal with Dutch amusement ride firm Vekoma. The agreement allows Vekoma to sell Rocky Mountain Construction's roller coasters outside the North American market. In 2014, Kolmården Wildlife Park in Sweden announced plans to build the first Rocky Mountain coaster in Europe called Wildfire, which opened on June 28, 2016. To handle increased demand, Rocky Mountain Construction opened a new factory, twice the size of their existing one, in August 2014.
In a press release on April 11, 2023, amusement ride manufacturer Larson International, known for its Fire Ball models, merged with Rocky Mountain Construction.
As of June 2025[update], Rocky Mountain Construction has built or refurbished 29 roller coasters around the world. As of 2025, all of them are currently operating.
