This year continues to present its challenges, so I would like to start off this message by saying I hope you and yours are healthy and safe.

Construction carries on for the Summit building, and the general contractor, Clark | Lewis, continues infectious disease mitigation protocol on the construction site. Examples include frequent handwashing, establishing work protocols for social distancing, thorough cleaning of the site, use of personal protective equipment, requiring employees who are sick to stay home, and adhering to the Governor's Phase I Construction Restart COVID-19 Job Site Requirements.

Phase I of construction has wrapped up, as indicated by the completion of the structural framework on the east end. Work to be included in Phase II includes framing the suspended staircase along the Pine Street border. This staircase, or Hillclimb, will provide event attendee access from street level to the ballroom level on top.

The Addition project hit an important milestone when Olive Way traffic went back to its original path in early September. The temporary rerouting of Olive Way enabled construction of a portion of the loading dock, which ultimately will extend underground from Howell to the south edge of Olive between 9th and Boren.  Above the loading dock, starting at grade at the north edge of Olive, a new apartment building and office tower will eventually rise. See below for a before and after photo of the realignment; white arrows indicate traffic flow.

Also below is a time-lapse video capturing construction activity from August 2018 through August 2020. Olive Way, in its temporary rerouted state, is at the top of the video.

Summit is scheduled to open for business in mid-2022.

We really appreciate our clients and we know this is an extremely uncertain time to reimagine future events. Our staff continues to work remotely, and they are available to answer your questions about booking the Summit and Arch building separately or together as a package.
