RECENT PROJECTS
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-ft in depth, wet,
and dry sockets. Micropile arrays varied from 12 to 18
up to 65-ft in length.
