GEI Consultants | City of Sunny Isles Beach | RFQ 26-07-01 60 Brant Rock Seawall Stabilization Marshfield, MA | Town of Marshfield GEI worked with the Town of Marshfield to develop durable long-term solutions for stabilizing and reconstructing its severely deteriorated seawall system. GEI provided engineering services for the investigation and design of repairs to the seawall at Brant Rock in Marshfield, MA. This seawall had severe deterioration of the concrete and an area of collapsed wall resulting from a 2015 storm. The initial project scope was for an investigation including condition survey, wave analysis, and development of alternatives for repairs and upgrades to the existing seawalls. The study then progressed to the design of long-term repairs and upgrades to the wall based on GEI’s recommendations. This included obtaining the necessary regulatory approvals and providing final construction documents. Regulatory approval was obtained, and construction of the first phase was performed in 2018. GEI assisted the Town with preparing and filing grant applications to obtain design and construction funding for this project. The final design of Phase 1 included 570 linear feet of concrete seawall, which included 200 linear feet of rip rap armor stone to protect the toe of wall during high wave energy events. Wall height was also increased by 3.5 feet to provide improved flood protection to residents. The second phase included an additional 600 linear feet of seawall. Phase 2 construction was completed in 2022.
