As Boston has its first real snowfall of the year, work continues on the new Charlesview garage: a single-level, 110,000 s.f., underground structure that will span two city blocks when complete, as well as provide the foundation support for six buildings above grade.
Work has progressed so that nearly 100 percent of the perimeter concrete footings have been set, formed and poured, and two-thirds of the perimeter garage walls are complete. Interior footings and elevator pits are ongoing. Below slab utility work began this week. With a coordinated effort, aided by the mild winter thus far, construction on the garage proceeds on schedule, with the overall project slightly ahead of schedule for the projected autumn 2013 completion.
Make a two-acre hole in the ground, exposing earth all the way down to the clay layer. Then add about four inches of rain and tons of heavy construction equipment. Those have been the working conditions on the Charlesview site this week, and yet substantial progress has been made.
Upon reaching the bottom of the western portion of the excavation last week, JMA has coordinated the sitework and concrete subcontractors to place, form and pour the foundations for the perimeter wall of the garage. All this week, workers have had to continually manage the rainwater by trenching, draining, pumping and drying the areas where concrete is to be poured. Despite the challenging conditions, the first several hundred feet of foundation have been poured, including the full length of continuous footing along Litchfield Street, and about a third each of the northern and southern foundations. Next week, forms will go in place to start pouring the actual garage walls.
