Quincy, MA New England construction management firm Dellbrook|JKS has begun demolition work on the former Quincy Medical Center at 114 Whitwell St., alongside owner, FoxRock Properties and architect, Arrowstreet.

The demolition will be completed in three phases and remove roughly 345,000 s/f of vacant and functionally obsolete buildings.

Phase one will include the Eastern portion of the property, phase two will be the Western side, which includes the former emergency department, and phase three will be the tall middle portion.

Demolition work is expected to be completed by the end of July. Shortly thereafter, ground-up construction of four new buildings, which will include a total of 465 multi-family residential units, will begin.

The 19,500 s/f historic Administration Building will be preserved and transformed into an adaptive reuse structure with amenity spaces and a new addition.

“We’re excited to execute a demolition of this scale in our own backyard while also preserving a major architectural landmark of Quincy in the Administration Building,” said Dellbrook|JKS project manager Tim Dann. “This site has a lot of history, so incorporating elements of the former structure with the new construction is going to create a wonderful final product.”
