What's New

  • Tower Crane Update
    Virginia Mason and our work team are deeply committed to ensuring 100-percent safety for our neighbors and our team. As previously communicated, a tower crane is expected to be erected on the construction site within the next couple weeks, and we will implement a thorough safety and communications effort to keep you informed. At any time, if you have questions, please do not hesitate to contact us (contact information listed at the end of this Web page).

  • Mass excavation on the site is complete. This means the bulk of material has been hauled out of the hole, and shoring is also complete.

  • We will continue to pour concrete on a periodic basis to prepare for the building foundation. Lane and street closures are listed below.

  • We are preparing for the mat slab to be poured. This is a six-foot thick concrete slab that is the main support structure for the building. It will be done in three pieces, the first of which will be poured Friday, July 25.

  • Periodically next week, there will be steel-bar deliveries using the smaller, 50-ton crane that is now on site.

  • A new 180-ton crane was erected on Spring Street. This will remain on site until the tower crane is erected, then both the 180- and 50-ton cranes will be removed.

  • Parking spaces along the north, westbound lane of Seneca, which were previously closed, are now available for public use.

What to Expect This Weekend
