Project Highlights
  • Structural Engineer of Record for the original building
  • Multi-purpose complex for all seasons
  • Combination of structural systems and materials expand the building’s original footprint

Andover Community Center Expansion met the needs of a growing population and greater demand for recreational and meeting spaces. The City of Andover collaborated with the YMCA to expand its 15-year-old community center. MBJ was Structural Engineer of Record for the original 130,000-square-foot building which is primarily framed in structural steel with concrete bearing walls and 120-foot roof spans. The original facility features a gymnasium, pools, fitness/workout areas, an 800-seat hockey arena, concessions and a 59,000-square-foot fieldhouse. The expansion added fitness areas, a new gym, new childcare areas, and an office space on the southeast side of the overall building and a new sports arena, lobby, and office space on the west side. A combination of structural systems and materials were utilized to expand the building’s original footprint.

The expansion project consisted of three major additions including expansions to the existing facility as well as renovations at several main entries of the building. The existing entry and lobby spine use glulam framing to support upper floors and portions of the roof, while the new west side entry and lobby area utilize structural steel clad in wood. By doing so, MBJ was able to create a similar aesthetic while providing cost savings to the owner. The new arena portion of the addition is structured with CMU and precast bearing walls, as well as structural steel, all which supported long span roof framing. The 2nd floor framing is partially supported by the long span roof framing which added complexity and design requirements for the long span roof framing to ensure these portions of the floor performed adequately as a space for the public to gather. MBJ utilized similar structural systems for the northwest portion of the expansion which includes a new gym as well as office and lobby spaces. Additionally, the new additions interfaced with much of the existing building perimeter and substantial upgrades to the existing portion of the building required structural retrofit to portions of the existing structural framing.

Pressure from the owner and public funding required an aggressive value engineering process. MBJ was instrumental in helping the architect and builder bring the project back into the budget needs of the owner.
