At the beautiful end to a soggy week, here are several photos from above the garage deck, as a 52-unit, mixed use building along Western Ave reaches its full height, and from below the deck, as concrete and plumbing work continues apace.
Work continues rapidly this week with additional concrete pours scheduled on the deck and garage levels. Crews work quickly ahead of the pours on the structural steel connections and detailing, installing the metal deck and on the subslab systems. The deck structure now enables work to continue on both levels simultaneously. See the pictures below from around the garage construction.
It has been an exciting few weeks on the Charlesview site as the garage structure has been quickly erected. What a difference two weeks can make at this stage of construction!
The first concrete deck over the roof of the garage is being poured by concrete sub JL Marshall today. This particular pour is an important step in the construction sequencing; that section is where the crane will sit to erect the first Western Ave midrise once the concrete cures to the proper strength next month. The garage floor slab pours will follow each deck-level pour.

Some images from the site as structural steel erection proceeds rapidly across the garage level. Concrete pouring of the slab on deck should begin next week, weather permitting.

The crane arrived this week with the first sequences of steel
Beginning this past Monday, steel that had been fabricated in Maine began arriving on site. The superstructure of the garage has been quickly going into place over the first few days, beginning on the west side of the garage.
After an incredibly mild winter and a carefully coordinated effort by JMA (general contractor), J. Derenzo Co. (sitework) and JL Marshall (concrete), the foundations will be substantially completed in the next week. A small portion of the garage–about 10 isolated footings and a section of wall–will remain unfinished so the earthen ramp can allow a crane and other equipment to continue to access the garage level for another few months.
The garage structure is over 110,000 square feet in area, so what the team has accomplished this winter is the equivelent of building a structure the size of the old K-Mart/Office Max building out of reinforced concrete, underground, beneath the water table.
This milestone also signals an important direction for the project: Up.
Steel will begin to arrive in early March for the erection of the garage structure. By late spring, the steel will be back up to grade level and the structure of the two largest mixed use buildings will commence.
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.
Over the holidays, JMA, J. Derenzo Co. (site contractor) and J.L. Marshall (concrete) continued progress on the garage structure. Excavation is nearing an end as soil removal will finish near the end of the month. As the excavation bottom has become available, formwork and reinforcing rebar has been placed and concrete foundations have been poured. Nearly three-quarters of the perimeter footings are complete.
Above the footings, nearly a third of the garage walls have already been completed. The garage work continues to benefit from the mild winter weather (until today!) and JMA aims to begin installing the garage deck steel in March.
