Hi Nell:

I am attaching the images we reviewed today at our meeting.

Here is a summary of our lighting strategy:

*         The Crinkle Wall is proposed to be illuminated by ground lights and lights mounted on armatures attached to the roof. The intent is to wash the surface of the glass with light and illuminate the aluminum framing that supports the glass. We propose to have the light pulse in varying intensities to create a visual sense of movement to amplify the waving geometry of the curtain wall system.

*         On the exterior walls of the seventh floor, we propose to install LED ILight Plexineon light strips on the surface of the exterior wall panels. The goal is to create a "nightlight" atmosphere for the outdoor decks at the seventh level while integrating the fixtures with the pattern of the architectural panels.

*         The rest of our exterior lighting is consistent with our original submission.

On exterior signage, we will proceed as follows:

*         We will request from Hyatt permission to specify the body of the signage to be silver to match the window frames of the building.

*         On the East Elevation, we will lower the sign to align with the head of the second floor windows and proportion the sign box to match the size of a "D" panel of the exterior rain screen system. This will integrate the sign panel size with the exterior paneling system of the building.

We will let you know if Hyatt will accept the requested changes to the sign package as soon as we hear from them. In the meantime if please let us know if the exterior lighting strategy is acceptable. Assuming it is approved, we will integrate the strategy into our construction documents and generate a photometric analysis to submit for approval.

Thanks for your help. Have a great vacation.

Best regards.
