J. Derenzo Co. manages unforeseen site conditions to bring project online on schedule

J. Derenzo Co. performed extensive exploratory and site work on this dense downtown Boston parcel. The team drilled test pits, relocated a 30" water main, excavated 14' below grade and prepped the foundation to make way for a future 11-story high rise. Situated across from the Boston Garden and atop operating MBTA lines, the site is extremely sensitive and the team has taken great care to properly schedule equipment mobilization, trucking routes, deliveries and material offloading.

Because tunnels beneath the proposed foundation prevented conventional earth support, the installed a unique gravity-flowable fill wall earth support system for the basement excavation, also known as a Support of Excavation (SOE) wall.
