A series of geotechnical studies spanning 15 years have been performed by AKA for various clients on San Bruno Mountain. The studies pertain to four towers, two satellite dish areas with six dishes each, and miscellaneous support buildings to provide improved communications along the San Francisco peninsula area of the San Francisco Bay. Towers range in height from approximately 200 to 300 feet.
A new tower and communications building were planned for Sunol Peak to reach eastern Alameda County. AKA performed geologic and geotechnical studies and recommended deep caisson foundations to carry the large vertical and lateral loads on the facilities. Downhole inspections of all caissons were performed by AKA during construction along with monitoring of other foundation and grading operations.
A 90-foot-high television broadcasting tower topped by a 46-foot antenna replaced one of the existing towers on the north peak of Mount Diablo (see arrow for location). Detailed geologic and geotechnical studies by AKA, including specific evaluations related to slope stability and wind velocity, were performed.
