The slurry wall was constructed through layers of clay, sand, glacial till and bedrock with a combination of clamshell buckets and Soilmec Hydromill cutter. Due to the close proximity of this project to other Dana-Farber buildings and the MATEP power plant, a Hydromill cutter was specified for excavation in order to limit vibrations and effects on medical and laboratory facilities and power plant equipment.
The deep slurry wall panels were embedded 2 ft to 3 ft into competent bedrock. The Hydromill cutter was key in advancing through Diabase bedrock, which was encountered in several panels. The shallow slurry wall panels installed along Brookline Avenue were installed for a below ground mechanical space.
Special excavation procedures were developed and utilized for construction of two corner panels that interface with the existing Dana-Farber Smith Building slurry wall.
