As a complement to our geotechnical consulting services, ZGA also provides geotechnical design services for both private and public sector projects. We can work with you toward production of detailed design documents and take projects from design analysis through preparation of plans and specifications for:
- Structural earth/mechanically stabilized earth retaining walls and slopes
- Soil nail retaining walls
- Cantilever soldier pile retaining walls
- Landslide mitigation
- Ground improvement
ZGA specializes in the design of structural earth and mechanically stabilized earth retaining walls and slopes. One of our principal engineers, Rob Ross, has been the engineer of record for well over one million square feet of retaining wall face in the greater Northwest and Canada. We work closely with clients and other engineers on retaining wall projects to develop a detailed understanding of existing and future conditions that may affect design and construction. We then develop site-specific construction plans for the walls, including plan and elevation views and necessary construction details. We use state-of-the-art analysis techniques—including displacement-based seismic design and WSDOT’s k-stiffness method, which typically result in lower cost designs than traditional methods.
