Ohlone College

Allana Buick & Bers, Inc. (ABB) teamed with tBP Architecture to provide building envelope consulting services for 8 buildings on the Ohlone College Campus located in Fremont, California.

These buildings were constructed in 1976 and are one, two and three stories, clad in cement plaster (stucco) over concrete walls, or stucco over light gauge metal and wood framed walls. The walls exhibited significant cracking which appeared to be widespread and there were leaks in the stucco-covered window soffits, windows and other exterior building components. In addition to the exterior wall issues, there were leaks in the below grade waterproofing and failures in the deck waterproofing components.

The investigation allowed us to pinpoint the causes of the stucco cracking and water infiltration issues, back to the original construction. Our detailed findings report included a repair plan that included the repair of the delaminating and cracking stucco at various locations, securing new expanded metal lath over the concrete substrate and repairing expansion joint assembles. ABB also provided analysis of the breezeways, siding and trim and water features and made repair recommendations accordingly. Following the investigation phase ABB provided construction documents and construction administration to repair the building envelope issues.
