• GOMACO University

  GOMACO University began as an in-house customer training program in the early 1970s. The first training sessions were held in Godbersen-Smith Construction Company’s conference room. Then, in 1975, GOMACO leased a building along Highways 59 & 175. The new GOMACO Education Center consisted of a classroom large enough to accommodate 18 students. The classroom portion of the program consisted of lectures and discussions illustrated with drawings and slides. Physical demonstrations of components were also presented in the classroom.

  The program was a success and outgrew the Education Center. In 1979, GOMACO purchased the diesel generating plant from Iowa Public Service Company in Ida Grove. The building had housed a six-cylinder and an eight-cylinder engine. The huge diesel engines were dismantled and scrapped and GOMACO remodeled the building to create GOMACO University. The remodel included adding a second story, which now houses Mr. G’s 1920s speakeasy.
  

  The new University opened its doors for the first class in the modern facility on April 21, 1980. A second facility was added to the campus in 2001, the GOMACO University Paving Center.

  Dean Bengford served as the instructor for the 1975 and 1976 school season. Dennis Clausen served as Director of Training until his retirement in 2018. Rod Schneider was named Director of Training, starting with the 2019 class season.

• Four-Track Commander IV Barrier Machine

  The four-track Commander IV barrier machine was introduced in 1978 with a center-mounted barrier mold under the machine frame. It allowed for free flowing traffic on both sides of the machine while slipforming. The mold adjusted hydraulically on either side or on both sides up to 24 inches (610 mm) above the standard barrier height. The extra height created a glare screen to block the headlights of oncoming cars. The Commander IV was sensored for grade and steering and moved with guidance from a GOMACO sensor stringline set to the side of the machine for consistent control on the changing grade.

• Rock Hopper For PS-2600 Placer/Spreader

  A customer in Indiana approached us needing a machine that could carry base material, rather than push a pile like past placer/spreaders. After the base material was placed, they wanted to be able to convert the machine back to a concrete placer/spreader. The PS-2600 with a rock hopper was developed. In 2002, an RTP-500 was used to place the stone base material into the rock hopper on the PS-2600.

   

  

  Rock base material is placed into a rock hopper on a PS-2600. The rock is spread 28 feet (8.5 m) wide and then a roller compacts it to finish the base on this project in Coldwater, Michigan.
