Our History

Leading the way in concrete construction.

For nearly a century, we have had a role in innovating newer and better ways of doing concrete construction. From our beginnings in concrete formwork, through our role in major Chicago landmarks like Comiskey Park and the John Hancock Center, to breakthrough uses of 3D modeling today, we have never been satisfied leaving anything as is.


After almost 90 years in business, and since 1998 performing full service concrete construction, Adjustable Forms is renamed Adjustable Concrete Construction. The name change aligns with the company’s commitment to unparalleled expertise and service in the concrete industry.

Adjustable Forms becomes the first contractor in Chicago to successfully model and fully detail a reinforced concrete frame in full 3D in a BIM environment with the completion of Clark & Grand Hotels. The modeling included both fabrication-level rebar detailing, as well as shop drawings produced directly from the model.

As the industry began to shift from a two dimensional drafting environment to three, Adjustable Forms begins utilizing Building Information Modeling as an integral part of its operations.

Concrete Construction Magazine recognizes Adjustable Forms as the 9th largest commercial concrete contractor in the United States, with revenues exceeding $100 million. The previous three years, the company completes 19 high rise concrete frames in the Chicagoland area.

Adjustable Forms completes Northwestern University Ford Engineering Design Center, its first project recognized by the United States Green Building Council (USGBC) as LEED® Silver. This project marked the first of many LEED Certified projects completed by the company, and the start of a commitment towards sustainability in all aspects of our business.

Catering to the expanding concrete services it provided, Adjustable Forms purchases its first concrete pump and placing boom. Over the next decade, the company owns and operates one of the largest fleets of high rise concrete placing equipment in the Midwest.

The company is awarded the River East Center, a 60 story condominium, hotel and parking structure. This marked Adjustable Forms’ first project as a full service concrete contractor. Particularly impressive is that the project is not only the first foray into placing and finishing concrete, but that the project was the third tallest residential structure in the country at the time of construction. The project was a tremendous success, and solidified Adjustable Forms as a major player in the concrete construction industry.

Recognizing a shift in the Chicagoland market from separate formwork and placing contractors to full service concrete, Adjustable Forms begins bidding projects offering comprehensive concrete services. This marked the first time in our 70 year history that we supplemented our vast knowledge of formwork with concrete placing, finishing, hoisting, and reinforcing steel.

Adjustable Forms grows its office and administrative staff to support growing work in Chicagoland area.

Upon graduating from the University of Minnesota in Business and working summers as a laborer for the company, James E. Lindquist begins his career at Adjustable Forms in Chicago (pictured right with Elmer Lindquist).

Adjustable Forms provides concrete formwork services for one of the most celebrated skyscrapers of all time, The John Hancock Center. Rising 1,476 feet over the Chicago skyline, construction of the innovative structure pushed Adjustable Forms to the forefront of the concrete industry.

The mid 1950s brought the most rapid geographical expansion for Adjustable Forms in its history. In the decade alone, Adjustable Forms performed concrete formwork services in sixteen states. Notable projects included the Los Angeles Furniture Mart and Veteran Administration Hospitals in both Florida and Alabama.

Adjustable Forms constructs one of the most influential highrise structures in the world, the Ludwig Mies van der Rohe designed 860-880 North Lake Shore Drive. The twin 26-story apartments would open up the company to a segment of the market that would later become its trademark-high rise structures.

After graduating from the University of Minnesota in Civil Engineering and fulfilling his Naval service abroad, Lieutenant Commander Elmer H. Lindquist (pictured right) joined Adjustable Forms. His responsibilities included both sales and engineering out of the Chicago office.

Recognizing a challenging construction environment in Minnesota, the Adjustable Joist Company made a fateful decision that would allow it to grow to a level unimagined by its founders. Tickle and Geneter created a subsidiary concrete formwork company in Chicago named Adjustable Forms, with the intent on capturing a piece of the robust construction market in other regions of the country.

Realizing the potential of his newly acquired patent, R.F. Tickle teamed up with partner Harold Geneter to form a new concrete formwork company, fittingly named Adjustable Joist Company. Like Stambaugh before him, Tickle and Geneter struggled to get off the ground with their new company. Work became scarce as the construction industry suffered with the onset of the Great Depression.

While working in Minneapolis for a division of Republic Steel called Truscon, a young engineer named Russell W. Stambaugh develops an innovative new idea for the concrete construction industry. He designs and patents a formwork truss with a combination of adjustability and strength, while minimizing overall weight. While developing the idea, he started performing concrete construction. While the idea had merit, his truss did not achieve the success he had envisioned. Stambaugh sold his patent to co-worker R.F. Tickle.
