Outstanding Project Award Winner: Lyrik - Air Rights Parcel 12, Boston, MA-Video

Video Transcription

Video Summary

The presentation describes the development of Boston’s Parcel 12, a complex public-private air-rights project built over the Massachusetts Turnpike and active rail lines. Completed after years of planning and construction, the mixed-use development includes office and hotel towers, retail, parking, a subway entrance, and a public park.<br /><br />The site’s dense urban setting, variable ground conditions, shallow groundwater, buried debris, and nearby operating infrastructure demanded extensive investigation and collaboration with public agencies. Engineers used a combination of drilled micropiles, secant-pile and slurry walls, driven steel piles, and carefully staged excavation. Automated monitoring tracked railroad movement, while strict work windows and traffic management allowed construction to proceed without disrupting transportation services.<br /><br />The project successfully limited track movement and improved the surrounding area with safer pedestrian routes, a cycle track, transit access, and public space. Community input also shaped the design, preserving views through the site.
