Concord, MA – TFMoran Structural Engineers continue to work closely with Maugel Architects and construction manager Dellbrook JKS on the Nashawtuc Country Club in Concord as the project approaches its planned completion in June. The 45,000sf renovation project consists of a substantial redesign and expansion of the existing clubhouse. The finishes were removed to expose existing structural elements. Extensive structural modifications were completed to accommodate the new design.
The existing building was originally constructed in the 1960’s and was comprised of a steel-framed main level and a wood trussed roof system. Subsequent projects in the 1970s, 80s, 90s and early 2000s included additions comprised of a variety of building materials including conventional wood framing, steel, and concrete. Renovations to these framing systems include the relocation of columns, miscellaneous repairs, and upgrades to the lateral force-resisting system to resist wind and seismic forces.
The project also includes 15,000sf of additions to the structure. The most notable addition houses the new ballroom, exterior deck space, and a large three-season porch. Both spaces include vaulted ceilings. The ballroom features architecturally exposed steel roof trusses that were designed with conventional steel shapes for efficiency, constructability and architectural aesthetics.
The trusses support energy-efficient structural insulated panels that are factory-built and comprised of structural wood sheathing and rigid foam insulation. The roof structure is supported on a steel frame with a steel and concrete framed floor below. This framing provides lateral support to the existing building as well as the new addition.
The project has endured the inherent challenges of a renovation of this scale. The main building frame is complete and exterior decks continue to progress. The design and construction teams continue to collaborate to provide a safe, efficient and durable building structure for the club to enjoy for many years to come.
