I like that my job is different every day. It keeps things interesting. 
Lori provides geotechnical investigation, design, consultation and construction observation services for a variety of geotechnical engineering projects, with an emphasis on sites with reclaimed land. Her projects include everything from commercial and residential buildings, sports and school facilities, to bridges, seismic upgrades and roadway realignments. In addition, Lori provides services related to infrastructure improvements for new developments.
As Oakland office Geotechnical Group Manager, Lori enjoys sharing information with her Treadwell & Rollo colleagues; each day in this team-based business is rich with interactions. During her years at Treadwell & Rollo, Lori has enjoyed seeing the business expand and believes the firm will "continue to maintain its reputation for technical excellence while expanding into new geographical regions and types of work."
