Department of Veterans Affairs, Roseburg VAMC Seismic Upgrades, Phase 1
Client: Department of Veterans Affairs
Year: 2024 - 2025
Location: Roseburg, OR
Features:
Geotechnical engineering for a multi-phase seismic improvement program at an active VA Medical Center.
Performed site-specific seismic hazard analyses and ground response evaluations in accordance with ASCE 7-16.
Completed deep subsurface investigations in constrained, occupied healthcare facilities.
Developed geotechnical recommendations supporting seismic resilience, foundation design, and phased construction.
Coordinated closely with USACE, VA, and HDR throughout design development and ongoing project delivery.
Project Summary
Central Engineering Services is providing geotechnical engineering services for Phase 1 of the seismic improvements program at the Roseburg VA Medical Center in Roseburg, Oregon. Managed by the U.S. Army Corps of Engineers, the project supports the modernization of campus infrastructure to meet current seismic performance standards while enhancing the long-term resiliency of this critical healthcare facility.
Working within an active medical campus, Central is performing detailed subsurface investigations, seismic hazard analyses, and engineering evaluations to support future facility improvements while minimizing disruption to ongoing hospital operations.
Scope of Work
Central Engineering Services is leading the geotechnical engineering effort for this multi-phase seismic improvement project, providing comprehensive subsurface investigations, laboratory testing, and advanced seismic analyses to support design and construction. Our team performed deep rotary borings, rock coring, in-situ testing, and site characterization to evaluate subsurface conditions and develop site-specific response spectra using the procedures outlined in Chapter 21 of ASCE 7-16. Central also developed foundation, excavation, grading, and earthwork recommendations, prepared geotechnical reports and UFGS specifications compliant with VA and USACE requirements, and continues to support the project through design coordination, QA/QC reviews, milestone submittals, and ongoing collaboration with HDR, USACE, and VA project stakeholders.
Features:
Performed deep rotary borings, rock coring, and in-situ testing within an occupied medical campus.
Conducted probabilistic and deterministic seismic hazard analyses and site-specific ground response modeling.
Developed seismic site classifications in accordance with ASCE 7-16 and International Building Code (IBC) requirements.
Prepared foundation, grading, excavation sequencing, and slope stability recommendations to support seismic improvements.
Developed UFGS-compliant geotechnical reports and technical specifications meeting VA and USACE design standards.
Coordinated field activities using phased mobilizations, low-noise drilling methods, and strict safety protocols to minimize impacts to hospital operations.
Continues to provide design support through weekly coordination meetings, quality assurance reviews, and phased design deliverables.
Results:
Central's geotechnical and seismic engineering expertise is helping advance one of the VA's critical seismic resiliency initiatives in the Pacific Northwest. By delivering technically rigorous geotechnical investigations, site-specific seismic analyses, and construction-focused recommendations within an active healthcare environment, Central is supporting the development of safer, more resilient medical facilities while helping USACE and the Department of Veterans Affairs meet long-term infrastructure and patient care objectives.
