J Derenzo Co. performed excavation, blasting and managed the earth support work for this new Brigham & Women’s Hospital garage project with Walsh Brothers.
The five-story garage features an earth support system of whalers and H-beams. J Derenzo’s team blasted and excavated ledge to make way for the excavation. Because the buildings immediately surrounding the hole are occupied and operating, the blasting was timed to most effectively mitigate impact on abutters.
Situated in the dense Longwood Medical area of Boston with no laydown area outside the building footprint, Derenzo’s crews created an intricately timed trucking schedule to allow one truck in and one truck out to manage debris removal.
