Five buildings were demolished in the last 6 weeks along Mass Ave and Columbia Street. The building debris is being removed to prepare for the basement and foundations for the 6-story building on Columbia Street and the Mass Ave garage.
FOUNDATIONS ALONG COLUMBIA STREET
Rigs will install steel sheeting for the Columbia Street basement. Some vibration is normal for about a week. Afterward for about 3 weeks, holes will be drilled and deep steel piles will be hammered down to bearing soils. Concrete formed foundations and basement should be completed by March 2018.
FOUNDATIONS ALONG MASS AVE
Slurry walls and foundations for a 2-story below-grade garage will start in December. The garage should be completed late-spring 2018.
