Koch, Chun, Knobloch & Associates, Inc. was established in 1946 and has been operating without a break in service since that time. The corporation is licensed for engineering service in both California and Nevada and is certified as a California Small Business Enterprise.

The company was founded by Carl R. Koch P.E. in 1946. Joe R. Chun P.E. joined the company in 1949, and became a partner in 1965. During that time the company completed designs on a number of California landmark buildings; the Sacramento Sutter Club, Sacramento County Library and Administration Building, Sacramento County Courthouse, Tahoe Truckee High School, Foothill High School, Columbia College, Channel 10 KXTV Station, the Sacramento Bee, Sutter General Hospital, Sutter Memorial Hospital, and Sacramento County Hospital which subsequently became the University of California Davis, Medical Center. In 1970 Mr. Koch achieved emeritus status. Between 1970 and 1987 Joe R. Chun was owner and President of the company, than known as Koch-Chun and Associates. The company continued to influence power and lighting design in California with the Lincoln Plaza and the Capital Bank of Commerce high rise buildings in Sacramento.

As California changed with new technological industries and the increased use of personal computers in business and the classroom, the company experienced similar growth and change. In April 1987 the company became Koch, Chun, Knobloch and Associates with Senior Design Engineers Donald R. Knobloch Sr., Donald R. Knobloch P.E., Steven A. Carpenter and Marlene Chun Lukenbill being added as partners to the firm. Staying on the leading edge of technology, the company added computer aided drafting and design techniques to its established computer program. It purchased and designed software to meet its own custom requirements. The years 1987 through 1997 presented new building challenges with an increase in data processing and computer center projects. Significant projects included the McClellan AFB Aircraft Accessory Complex, Modesto Irrigation District Energy Management Center, Sacramento Municipal Utility District Energy Management Center, The California State Franchise Tax Board Phase II, McGeorge School of Law Remodel, and the Merced County Courthouse.

Steven A. Carpenter, President and Donald R. Knobloch, Vice President assumed full ownership of KCKA in 1997. They continue to lead the company with the established principles of client centered service and the incorporation of the best technological advances available in electrical building design.
