Twin tower update – what’s up next at the big dig?

Ed Note: Thanks to Joan H. we’ve found the web site for updates for the construction of the twin towers between Skyline and the Frye Museum: http://www.707terryproject.com/. We’ll try to post their updates as they occur on their website.

The three-level podium will include space for a restaurant, café and other retail uses, as well as artwork displayed in the lobby.  The tower will also have six floors of underground parking for both residential and commercial use.

Construction Bulletins:

Friday, October 19, 2018 UPDATE

  • Earthwork activities will continue during select Saturdays in an effort to expedite the mass excavation scope and to minimize overall night hauling durations.
  • Saturday October 20th will have the extension of the conveyor arrive and install.  This will not cause any long term traffic issues or road closures.
  • Excavation and Shoring is at approximately 50% with completion of mass excavation projected to be the middle of November.
  • Night hauling is still continuing and is projected to carry on until the end of the excavation – scheduled to complete in November.
  • Daytime earthworks on select Saturdays
  • Shoring Equipment Demobilization is currently scheduled for mid to late November. This work will require road closures on Terry and Columbia.
  • Conveyor Demobilization is currently scheduled for the later part of November. This work will require road closures on Terry and Columbia.
  • Tower Crane Mobilization and Erection is scheduled for late November or Early December. This will occur on a Saturday. This work will require road closures on Terry and Columbia.

October Activities

  • Mass excavation is still underway.  As of today, approximately 30% of the dirt has been removed from site
  • Piling has been completed and the large drilling equipment has been moved off site. A smaller rig has been mobilized to perform soil nailing operations.
  • Soil Nails are being installed with shot-crete facing. This work is about two lifts or 20 feet below grade
  • Two trailers for field personnel have been mobilized and are currently being set up to house Graham staff
  • Night hauling of dirt will continue this next week and will be maintained for the following 7-8 weeks
  • October 6th is the confirmed date to mobilize and install the earthwork conveyor. This will require a shut down of Terry Ave and Columbia Street during the morning hours of 12:00a.m. through 12:00p.m. Terry Avenue will then be opened up to the public with some earthwork activities still occurring on the street in order to test and calibrate the conveyor.
  • Ongoing survey activities on site as well as survey monitoring of neighboring properties continues.
  • Trailers will be installed up on the scaffolding along Columbia within the next month.
