Providence prepared precast concrete erection drawings, fabrication shop drawings and structural designs for spandrels and related connections. The design of connections to the supporting cast-in-place concrete structure were very challenging due to numerous design constraints. Such restraints included interference with interior architectural finishes and HVAC equipment, construction tolerances, curtain wall channel embeds and rebar in the supporting structure. Several connection concepts were considered for this project, each one having its own pros and cons. Our expertise was essential to the design coordination process.
