New Parking Garage Increases Access and Drives Activity in Downtown Springfield

This project delivered a new five-story, 350,000 square-foot precast concrete parking garage with capacity for 817 vehicles, founded on more than 600 rigid inclusions to support long-term structural performance. The garage includes three enclosed stair cores and three elevators for safe, efficient circulation. The first level houses garage administration offices, MEP systems, storage areas, and a 9,500 SF shell space reserved for future retail use.

Interior construction emphasizes durability and low maintenance through the use of architectural precast walls, CMU partitions, gypsum wallboard assemblies, polished concrete floors, metal and GWB ceilings, and stainless steel doors and hardware. The scope included complete plumbing, fire protection, mechanical, electrical, data, communications systems, and substantial civil and site work to integrate the facility with the surrounding streetscape.

The project extends beyond the structure to enhance the public realm with an outdoor plaza featuring berm seating, pavers, planters, and a large concrete patio with lighting for public events. The Landing, located between the garage and the MassMutual Center, was converted into a pedestrian-only corridor with concrete sidewalks, new lighting, trees, and site furnishings.

• Preconstruction Emphasis: Work included developing the DD budget, early design assist package for precast concrete, sitework and rigid inclusions, trade bid prequalification input, and the final GMP bid package for remaining trades.
• BIM Services: Our team used laser scanning in conjunction with BIM to develop accurate models of the as-built condition to fully coordinate the new MEP and the finish systems.
• Logistically Complex Site:
  • The site was located in a dense urban area bordered by heavily traveled sidewalks and roadways.
  • Required deep coordination with the City of Springfield and local agencies within the City.
  • The project team coordinated closely with the Mass Mutual Center as construction was adjacent to this very active public facility.
• Utility Work: The existing structure was already demolished. DOC needed to provide major utility work to add structures and tie newly updated utilities to the existing ones per the Springfield Water and Sewer Department.
