Operable windows were shop installed into the unitized curtain wall panels and set as complete glazed units.

In order to meet the construction schedule requirements, all products other than the main entry stair glass guardrail were pre- fabricated based upon agreed construction tolerances.

The sunshade blades are mounted on pivots that are actuated by a lever arm (noted as 14) and attached to the motor shaft. The electrical portion of the operable sunshades required compli- ance with NEC for LA Building Department approval. The system wasn’t UL Listed as an assembly when fabricated, but compliance was obtained during installation through on-site modifications.

As stated by the exterior wall consultant (Jon Weir, JA Weir Associates), “This was a complex façade project that went together seamlessly, due to an architectural firm that was willing to sit down and roll up their sleeves anytime that it was needed, and a highly skilled group of contractors who col- laborated as well as anyone on the design team could ask."
