New 7-story condo development on Nevins Hill, with 55 new condominium units, outdoor terraces, level 2 amenity deck, and ground floor stacker parking system.

Structural system:

• 6-stories of light gage bearing wall and New Millenium Versa-Dek
  • Versa-Dek slab clear spans to bearing walls with no dropped beams
• Level 2 podium – to transfer light gage bearing walls from condo above
  • Originally designed as post-tensioned concrete to minimize structural depth and fit below high-rise
  • Redesigned as composite steel podium for cost reasons.  Grading was adjusted to accommodate the increased depth.
• Foundations – spread footings on ground improvement

H+O studied various structural systems, in the end, the team landed on the light gage (LGMF) solution in order to fit 7-stories under 70ft.  The 70ft threshold is the high-rise trigger in Massachusetts.
