Transportation Geohazard Contractors
Transportation departments link communities and economies across mountain ranges and complex terrain. GRW mitigates rock and slope risks so geohazards don’t derail safety, level of service, or project delivery
Understanding Transportation Geohazards
What we work around
We work on rock cuts, embankments, benches, bridge approaches, and rail interfaces in steep terrain along the highway right-of-way
problems we deal with
We resolve rockfall, raveling faces, over-steepened cuts, and shallow slides that put lanes, structures, and corridors at risk
our place
We join the team as the steep-slope specialist—typically as a speciality subcontractor or as prime for geohazard and slope-stability packages
Mitigating Transportation Geohazard Risk's
Risks Of Working On Transportation Sites
Transportation projects frequently push alignments through weathered rock, over-steepened cuts, and confined rights-of-way where rockfall and localized slope failures are persistent threats.
These hazards are difficult to control from the roadway with conventional earthworks crews, especially under limited lane closures, tight detour options, and high public and agency scrutiny.
Our Response
GRW takes responsibility for the steep-slope and rockfall scopes, using high-angle access, specialty rigs, and planned staging to work above and beside live traffic and rail.
We coordinate with owner engineers, prime contractors to sequence our work without disrupting the critical path.
How We Add Value
We coordinate with owner engineers, prime contractors to sequence our work without disrupting the critical path.
Our work reduces geotechnical uncertainty, reduces project risk, and protects workers and public from hazards. For decision-makers, this means fewer surprises on the steepest, most exposed sections of the corridor and a specialist contractor you can trust with high-risk scopes
Common Transportation Geohazard Problems
- Steep or unstable rock and soil slopes pose risk above highways, interchanges, bridges, or rail lines.
- Rockfall or slope movement threatening the traveling public, workforces, or assets
- Work areas accessible only from narrow benches, rope systems, or specialty rigs rather than from the roadway platform.
- A contractor familiar with DoT specs. for materials, instalation and texting is desired
- Specialized steep slope expertise is needed where safety and schedule are critical factors on the project
Project Highlight
California Route 36 Emergency Landslide Repair
Location: Humboldt County, CA
Sector: Transportation
Scope: GRW was retained under an emergency contract to assist in the development and construction of a series of mitigation measures at two locations along Route 36. A combination of hazard mitigation techniques and drapery installation was required to efficiently restore safe access to the roadway. the project.
