Tocci’s occupied renovation in South Boston is making steady progress.
Tocci’s Superintendent fills in details on 645, the two-story, 150,000 sf commercial building:
At 645 Summer Street, we are moving along despite the weather with the shotcrete on the exterior shear walls. This involves installing a vertical rebar mat that is attached to angles that are welded to the building’s structure, then covering the area with shotcrete. Shotcrete is another name for gunite; the material used in a lot of in-ground pools. It is a mixture of sand, Portland cement and a small amount of water that is shot on to the surface at a high velocity.
Inside the building we are installing interior lintels and removing block at the majority of the window openings in preparation for the windows arriving in late February. We are continuing with an extensive amount of structural steel work to support the roof pavilion that will be built. This includes column and beam stiffeners, knee bracing, and installing 80 two-piece joists. On the first floor Tocci has relocated the current tenants’ office space and begun demolition to make way for a new passenger elevator and grand staircase.
