Fenway Residence Inn by Marriott

Urban redevelopment is an ongoing process and the Fenway neighborhood in Boston is getting a new Residence Inn by Marriott who recognizes the potential for this neighborhood and energizing it’s economy.

This project is owned by Boylston Properties of Boston, Massachusetts, and is a 120,000 sq. ft., eight-story building with 175 guest rooms. The $60 million project will include 6,000 sq. ft. of ground level retail and restaurant space. It will also have 50 parking spaces below ground, a fitness center, meeting rooms, indoor rooftop swimming pool that opens up to a green rooftop terrace.

Hybrid Building System
Unique to this building is the use of the Girder-Slab System that allows for the steel construction to be erected and then the precast hollowcore planks to be installed. This Girder-Slab System uses a unique D-Beam® that supports the hollowcore planks which have notches cut into them to allow for grouting to seal the panel to the girder.

This Girder-Slab System developed by Girder-Slab Technologies, LLC, Cherry HIll, New Jersey allows for a very rapid construction schedule. Mike Weigand of J.P. Carrara & Sons, Inc., Middlebury, Vermont, project’s precaster said “speed of erection was one of the reasons for choosing precast.” In this case, the drawings were approved on July 27, 2012 and the hollowcore plank installation began on August 9th, ahead of the proposed schedule.

Antonino Donato, AIA, LEED AP, project manager from Group One Partners, Inc., Boston, Massachusetts, the architects for the project, stated there were several reasons for choosing precast hollowcore for this project. First, the underside of the plank became the finished ceiling, lower floor-to-floor height (used with D-beam in lieu of traditional steel) allowed for an additional floor to be added, precast concrete’s inherent fire rating, good sound transmission class (STC) rating (a quieter hotel room), and a faster project completion (other trades can access floor faster). Additionally Donato states that when it comes to cost- and time-savings, that the savings is not in the actual design but the “overall project completion time and project cost if designed properly.”

J.P. Carrara & Sons, Inc. manufactured the 920 (8in. x 8ft.) precast hollowcore planks. The larger width plank reduces the number of planks needed for the project and thus creating fewer seams that need grouting. The plank finish called “carpet ready” is a smooth surface ready for a direct flooring application.

Precast concrete is a perfect fit for building in tight urban areas. Construction with precast concrete takes up very little space beyond the building footprint illustrating precast’s versatility in the utilization of this hybrid building system.

This new Residence Inn will not only boost the economy in this changing area, it visually enhance the area and be a shining example of a new system and the possibilities it offers.
