GOMACO Corporation, an acronym for Godbersen Manufacturing Company, officially began selling equipment in 1965. The company manufactured and marketed three original products, the RC-120 side discharge conveyor, the F-500 double-oscillating screed finisher (U.S. Patent No. 3,299,786) and the Spanit® Work Bridge (U.S. Patent No. 0,857,158).
GOMACO Corporation was created to manufacture and market three original products, the RC-120 side-discharge conveyor, the F-500 double-oscillating screed finisher, and the Spanit Work Bridge.
1965 – GOMACO (Godbersen Manufacturing Company) was formed by Harold and Gary Godbersen
In 1966, GOMACO developed its cone drum or cylinder finisher for skewability and wider width bridge decks on freeways. That machine was introduced with a 36 inch (914 mm) cone and was the predecessor of today’s C-450 cylinder finisher, which was introduced in 1969. Of all the machines manufactured by GOMACO, the C-450 concrete finisher made GOMACO a recognized name in the construction industry in the late 1960s.
1966 – An electric cone finisher, U.S. Patent No. 3,450,011, was designed for skewed bridge decks and paving 60 feet (18.3 m) wide
1966 – Prototype electric form-riding cone finisher, U.S. Patent No. 3,450,001 and Canadian Patent No. 853,607
The GOMACO product line rapidly expanded in 1969 with new and prototype machines. An enlarged C-450 on tracks was named the 550 slipform paver for full-width city paving, interstate ramp work, factory floors or large parking areas. The 550 was available with integral curb attachments to allow contractors to spread and finish a full-width street and curbs in one pass. GOMACO engineers also had machines under development with the ability to trim grade for sidewalks, molds that could pave five foot (1.5 m) wide sidewalk, and a slipform machine capable of trimming and pouring 42 inch (1067 mm) wide curb with gutter.

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.
1975 - The GOMACO Education Center on Highways 59 & 175
GOMACO continued to enhance its line of equipment for secondary and street paving with the introduction of the HW-165 paver in 1975. The HW-165 was built for paving city streets, interchanges, ramps, alleys, secondary roads, and mainline widening without the expense of forms. Its features included: hydraulically-powered frame widening for fast width changes up to 18 feet (5.5 m), integral curb, fully proportional control system with cross slope control for accurate guidance from a single reference line or previously poured slab, interchangeable curb profiles, low profile hopper for easy concrete discharge from either or both sides, spreading auger, tamper bar and heavy-duty hydraulic vibrators, and tracks that could be raised hydraulically for pouring adjacent to existing concrete.

GOMACO introduced the CS-2400 concrete spreader. It was designed to spread and position concrete on widths up to 24 feet (7.3 m).
GOMACO’s successful international sales efforts were recognized in 1978. The company was presented an Iowa Governor’s Export Award at the Seventh Annual Governor’s Conference on Export Expansion. The award recognized GOMACO’s contribution to the state of Iowa in export excellence.
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.
June 1978 – Prototype Commander IV four-track barrier slipformer in Atlanta, Georgia
A specially-designed automated drilling assembly was designed to be sidemounted to either the GOMACO GT-6000 or Commander III in 1978. The drilling assembly was designed to increase production over the hand method of hole drilling with accuracy of hole placement and consistency of drilling depth. It also eliminated varying drill angles which could sometimes result from hand drilling.
1978 – Special multi-drilling attachment for vertical or horizontal drilling assuring alignment and depth
In 1979, Harold Godbersen was personally recognized when he was named Iowa Small Business Person by the U.S. Small Business Administration. The honor recognized his achievements in promoting the free enterprise system through GOMACO Corporation.

The GOMACO ScaraPlane III combined the latest construction equipment engineering technology with knowledge of cold planing. It offered exacting cutting tolerances with grade and slope control units and was designed for high-capacity production in one, two, or three inch (25, 51, or 76 mm) depth cuts. GOMACO’s unique POS-A-TROL (U.S. Patent No. 1,169,999) system monitored the engine load while governing propulsion speed to assure machine efficiency. Cutter tooth life was increased due to a cutterhead design which put the tooth at the proper cutting angle to the work base and GOMALOY™ (U.S. Patent No. 1,164,376), a metallurgic tooth holder design. One man could easily operate the ScaraPlane III from the enclosed cab on the front of the machine. The cab was human engineered by GOMACO with the operator and maximum operator efficiency in mind.

The In-The-Pan Dowel Bar Inserter (IDBI) is a system for European-style concrete paving incorporating dowel bar insertion into the paving mold. It was the latest in a series of GOMACO innovations in dowel bar insertion over the previous 13 years. The new patented design moved the DBI into the paving mold without extending the paving machine. It was a revolutionary idea that allowed the placement of dowel bars across a concrete slab and on-the-go with a GP-4000 two-track paver. It would enhance rideability through superelevations or severe vertical elevation changes. It also simplified transportation of the machine between job sites by eliminating the need to disassemble and reassemble the machine. The DBI and IDBI systems were granted several U.S. patents, including No. 5,101,360 in 1992, No. 5,190,397 and No. 5,209,602 in 1993, No. 5,924,817 and No. 5,941,659 in 1999, and No. 6,099,204 in 2000.
Stringless paving through the use of a laser system was accomplished in May 1995. A three-track Commander III was outfitted with a laser system from Laser Alignment.

The two-layer paving system for European-style paving involved a single mold design. Past applications used two placer/spreaders, one for each layer or having to extend a paving machine to great lengths for the second layer. GOMACO’s patented paving mold incorporated both layers into one mold without extending the paving machine. The mold featured leading vibrators, a spreading auger, and an adjustable strike-off for the first layer of concrete. The second layer system featured a hopper designed to be charged with a conveyor system, a spreading auger, and unique horizontal tube vibrators for consolidation before the second strike-off.
1995 – Two-layer paving system
GOMACO’s “little” GT-3200 was unveiled at CONEXPO-CON/AGG 1996. The GT-3200 was introduced as a “little” curb and gutter machine with more horsepower than any machine in its class.
