The Haven Park project was part of a 12-acre mixed use development in Rancho Cucamonga, California. The project comprised of two, 75,000 s.f. 3-story concrete tilt-up office buildings, two retail buildings totaling 21,200 s.f., and a freestanding two level parking structure.

Some of the challenges that faced the project included adapting the design and construction to a tight site as well as staying on top of an aggressive schedule. In addition to the shell construction, Oltmans provided core work as well for future financial, educational, and retail tenants such as casual restaurants, shops, and office related businesses. Oltmans also provided associated site development and off-site work, including street widening and new traffic signal.
