Project: TL13844

ECO to Boulevard

Client: SDG&E CSE Group

Contact: Timothy Moore

Scope: Performed 3rd party geotechnical and foundation design review, QA/QC inspection of 68 overhead transmission line-drilled piers and 4 micropile foundations.

Piers were 7-10 foot diameter, up to 84 feet in depth, wet, and dry sockets. Micropile arrays varied from 12 to 18 up to 65 feet in length.
