TFMoran provided structural engineering services for the new construction of six-story, multi-family residential building. The project is located on One Newport Avenue, between West Squantum and Arlington Streets in Quincy, Massachusetts. Developed by Arista Development and designed by KFP Architects, the new apartment building will include four stories, approximately 80,000sf of 80 residential units over two stories, approximately 50,000sf of above grade, open parking space.
Located within the footprint of an existing industrial building that is to be demolished, soil conditions were determined to consist of granular urban fill over a former marsh deposit of organic silt. Traditionally, these conditions would not be suitable for shallow spread footing foundations and would require a deep foundation system such as piles. Instead, in conjunction with Terracon Consultants, soil improvement techniques such as aggregate piers and stone columns were considered to help provide a suitable bearing surface for shallow foundations while keeping foundation costs to a minimum. These systems are intended to reinforce and increase the stiffness of the unsuitable layers, thereby increasing bearing capacity and reducing building settlement to tolerable levels.
The superstructure itself is considered “podium” style, consisting of wood-framed residential levels over concrete slabs on steel framing at the parking levels. A mix of one- and two-story units will be provided with ample parking, elevated patio spaces, spacious exercise and meeting rooms, and a roof deck overlooking the Quincy Bay. Demolition of the existing industrial building is expected to occur early spring 2018, with foundation work slated for mid-to-late spring 2018. The general contractor, RESKON Group, expects an overall completion of this new apartment building for fall 2019.
