Firm Notes

The Oltmans Construction Company has been in business since the 1932. Its first office building stood at 810 E. 8th Street in Los Angeles, CA, and opened in 1937. (See Oltmans Construction "J.O. Oltmans," accessed 09/15/2018.) The firm was legally incorporated in 1946, CA License #86393.

The firm became an important early adopter of "tilt-up" concrete construction in the 1940s. The company's web site stated: "Oltmans is the first to pioneer concrete tilt-up construction in Southern California. Our advancement in this field sets us apart from other commercial general contractors." (See Oltmans Construction "1940's Oltmans Pioneers Concrete Tilt-Up Construction," accessed 09/15/2018.) Other Southern California architects such as Irving J. Gill (1870-1936) and Rudolph Schindler (1887-1953) had begun using this method in the 1910s and 1920s. Gill employed "tilt-slab" construction first in CA for his patron Ellen Browning Scripps (1836-1932) at the La Jolla Women's Club in 1913.

By 1956, J.O. Oltmans had its main offices at 516 South Monterey Pass Road, Monterey Park, CA. (One source indicated its address to have been 1540 Monterey Pass Road. See "Construction Notices," Engineering News-Record, vol. 156, 1956, p. 92.)

From at least 1986 until 2018, the firm had its headquarters at 10005 Mission Mill Road, Whittier, CA 90601. (Tel: 562.948.4242 2018). In the 1980s, Oltmans opened offices in the Thousand Oaks neighborhood of Los Angeles, and branches in Northern California.

In 2001, Oltmans ranked as #138 of the Engineering News-Record's top 400 construction companies by revenue. (See Oltmans Construction, "2001 - ENR Top 400 Contractors," accessed 09/15/2018.)
