Nelson Legacy Group | Project One
Project One is the first building of a 22-acre mixed-use development plan in Redmond, WA. Construction involved the installation of a customized dewatering system utilizing deep dewatering wells and a retention system using soldier piles and lagging, with tieback anchors for lateral support. The soldier piles were installed using the CFA pile method which reduced cost and schedule for the project. The tieback anchors were placed on walers to allow for one tieback to be utilized for two soldier piles. Completing the final excavation and safe installation of the lagging boards required careful localized groundwater drawdown from the dewatering well system to enable the shoring work while also staying within the city discharge limitations.
