Projects

Forensic Investigation for Edenville Dam Failure

Edenville, MI · Water Resources · 2020

Project details

Independent forensic investigation of the 2020 static liquefaction failure of Edenville Dam, which impounded a lake with about 36,000 acre-ft of storage. Alvi Associates led the investigation of human factors and participated in all aspects of the physical factors investigation across hydrologic, hydraulic, geotechnical, and structural engineering disciplines. About 2,700 hours were spent by Alvi Associates on this investigation.

Forensic Investigation for Oroville Dam Spillway Incident

Oroville, CA · Water Resources · 2017

Project details

Independent forensic investigation of the 2017 spillway failure at Oroville Dam - the tallest dam in the United States at 770 feet. The President and Chief Engineer of Alvi Associates was one of six team members, leading the human factors investigation. This was the first major dam incident investigation in which human factors received equal attention to physical factors. Recovery cost was estimated at $1.1 billion.

Forensic Investigation and Gatehouse Anchorage System for Prettyboy Dam

Maryland · Water Resources

Project details

Abovewater and underwater inspection, materials testing, forensic investigation, stability analysis, and design of a $6 million underwater post-tensioned anchorage system - the first of its type in the world. The project was completed under budget and ahead of schedule and earned four engineering awards including the ASDSO National Rehabilitation Project of the Year.

Vessel Collision Study and Fender/Dolphin Systems for Route 5 Bridge

Virginia · Bridges

Project details

Major 21-span replacement bridge over the Chickahominy River. Alvi Associates performed a comprehensive marine vessel collision study and then used energy-based nonlinear design to create fender and dolphin systems protecting the bridge, including more than 100 piles in water depths up to 46 feet using an innovative partially-prestressed concrete approach.
