Geotechnical

Our engineers and geologists have decades of experience in helping our clients develop creative designs and solutions to their geotechnical problems.

Treadwell & Rollo’s geotechnical expertise is applied to projects as diverse as high-rise office towers to single-story buildings. Treadwell & Rollo's high-profile projects are continually in the spotlight. Since 2000, the San Francisco Business Times has listed the top 25 construction projects in San Francisco. Projects on the list include Mission Bay, AT&T Park and Four Seasons Hotel-to name but a few. We are proud that in any given year, we have been responsible for geotechnical services on over 50% of the listed projects. Our projects include:

• Major infrastructure 
• Urban developments
• Port developments
• Quarry planning
• Bridges
• Embankment dams
• Landfill slopes and covers
• Excavations for buildings
• Pipelines and utilities
• Road, rail and urban transit systems
• Tunnels and underground storage facilities

The technical disciplines employed include soil and rock mechanics, foundation engineering, geologic terrain and natural hazard evaluations, engineering geology, earthquake engineering, construction quality assurance and technical support of counsel. Because we provide our services both during the investigation and the construction stages, we have developed years of experience addressing the issues that architects, engineers and planners are faced with during design as well as the potential problems that contractors encounter during construction.
