Vincent J, Perrone • Geotechnical Engineering Consultant • About

Perrone Consulting, Inc, is a professional services corporation working in geotechnical and underground engineering disciplines. We specialize in clay behavior and soft ground engineering. Our practice areas include the design and construction of:

Foundations and embankments
Tunnels and caissons
Bulkheads and retaining walls
Forensic investigations

Slope stability and landslide repair
Shoring and underpinning
Pipelines
Soft ground engineering

Our clients benefit from hands-on direct involvement by experienced, senior engineering personnel in all phases of the project:

Program planning & underground risk management strategies. We provide consultation through all phases of your project to identify the best engineering solution and to identify potential underground risks that could affect construction costs. We develop practical recommendations to achieve your design goals while also minimizing subsurface risks through careful planning and execution of site explorations and contracting strategies.

Field exploration and laboratory testing. We conduct geotechnical explorations in all types of site access conditions that require specialized knowledge of exploration methods and their limitations.

Engineering design. We specialize in soft ground engineering for foundations, embankments, retaining walls and underground structures.

Contract document support. We develop earthwork and foundation specifications as well as prepare geotechnical baseline reports.

Forensic investigations. We participate in forensic studies involving failures of slopes, foundations, retaining walls, bulkheads, pipelines and earth structures.

VINCENT J. PERRONE, Ph.D., P.E.

Mr. Perrone has 30 years of experience in geotechnical design and construction of commercial/industrial developments, roads and bridges, pipelines, and water/wastewater treatment and port facilities. He specializes in clay behavior and soft ground engineering and he has designed numerous temporary and permanent retaining walls and bulkheads, landslide repairs, soft ground tunnels, caissons, and embankments. He was lead geotechnical design engineer on such major Northwest projects as the I-90 retaining walls on Mercer Island, the Wynoochee Hydroelectric Project, and several King County wastewater projects such as the 12-mile-long Renton Effluent Transfer System, Alki CSO Transfer System and West Seattle Tunnel, and the Interurban CSO Transfer System. He also managed the geotechnical program for King County’s Regional Wastewater Services Plan, authored the County’s geotechnical scoping guidelines manual and is currently a consultant for design of the Brightwater tunnel conveyance system.

Mr. Perrone has served as President of ASCE Kitsap branch and on the ASCE’s Geotechnical Engineering Journal publications committee and the ASTM technical journal as a reviewer of technical paper submittals. Mr. Perrone has participated in forensic engineering studies, and provided expert testimony for failures involving slopes, foundations, retaining walls and tunnels. In 1998 he completed a PhD dissertation on soft ground behavior and numerical modeling.
