Shoring & Dewatering for Project One Construction
Project One is the first building in the master plan to development of 22 acres around mix residential, office and retail use. The building will be mixed use commercial and residential featuring ground floor commercial use space and residential amenities.
Malcolm Drilling was contracted for the dewatering and installation of the retention systems. Malcolm started by installing 16 deep dewatering well systems around the project to temporarily lower groundwater levels. Extra customization was added to the dewatering system to allow localized groundwater drawdown while staying within the city discharge limitations.
Malcolm also installed shoring of the excavation consisting of soldier pile and lagging system with tieback soil anchors. The soldier piles were installed using the CFA pile method which reduced cost and schedule.
Completing the final depths of the shoring wall lagging boards required carefully tuned localized groundwater drawdown from the dewatering well system to enable the shoring work while also staying within the city discharge limitations.
