Geostructural Engineering
Provost & Pritchard’s Geostructural Team offers consultation, engineering and construction services for tunnels and alternative underground structures. The Geostructural Team brings an expansive portfolio of more than 400 projects over the past 35 years. These include water supply tunnels, hydroelectric facilities, wine caves, production mines, tunnel projects and alternate underground facilities across California.
Our diverse range of services is designed to address the unique needs of our clients. These services encompass:
- Geostructural engineering
- Construction management
- Client representation
- Agricultural solutions
- Water resources management
- Environmental consulting
- Structural engineering
- Hydrogeology
- Geographic Information Systems (GIS) services
- Surveying
- Planning, biological studies
Value Driven Approach
Provost & Pritchard’s typical approach to a Geostructural Engineering project is to work the project in phases. Our initial consultation phase helps determine the site and project constraints, assists with developing conceptual design of the project, and engages with other consultants on the team or assists with building the client’s team. After our initial phase and development of the project and scope, we provide subsurface investigation and reporting, and design of tunnels and portals in support of permit submittals. Additional work includes engineering services during construction that include performing geologic and engineering observations/tests, materials testing and special inspections during construction, addressing geotechnical/geostructural engineering and design issues during construction, and help the team facilitate a well-constructed project.
