Oltmans Construction Co. is proud to announce the completion of two, LEED certified buildings at Sierra Business Park for Oakmont Industrial Group. The two new buildings are built adjacent to the three large warehouse structures Oltmans constructed in 2005-2006. The buildings are type V-B, fully sprinklered, “shell” warehouse buildings with each including two trash enclosures, light standards, screen walls, and site work.

In addition, Oltmans provided off-site street improvements for the City of Fontana including curb and gutter, paving to center line on Tamarind Ave and new drive approaches on Santa Ana Ave. After the construction of the shell buildings and in a separate contract, Oltmans concluded the work with speculative tenant improvements for both Buildings D & F.
