Scratch the race...Seattle House just started a shoring revision. Methinks Clise will win this one.

What's in the shoring revision I wonder? I was thinking about the logistics of them doing the whole block in one big excavation. From an SDOT position, it seems like they should technically be able to call it is part of their SIP to excavate the whole block then fill in the alley using an SDOT approved fill material.
It's basically a standard road/alley reconstruction except instead of replacing 8" of sub-base material they're replacing like 100' of sub-base. It would cost them a bunch in street use permits but I'm sure the cost savings would still create value for both projects.
Anyone else seen a project do something like this?

Or maybe the second job is going with internal bracing. If they're facing a long delay, maybe the extra cost would be worth it?

In any case I wonder if they can phase the shoring so at least a few weeks worth can happen without shoring the alley side. The logistics of shoring part of the site while leaving a bench on the east...workable?

Get the crew from 1200 Stewart on it. We’ll be talking about this in 5 years.

That sounds easy enough, but in Seattle alley's are used extensively to route utilities, this block is no different I assume and would be too difficult/costly to re-route utilities just to make it an easier dig for the adjacent developer.

BB6 chimes in on the new design and brings up some interesting points:

10/4/2019 Update:

  • Clise Twins (2301 7th Ave): Complete Automotive building completely removed, leaving only the foundation and surface lot.
  • Seattle House (2300 6th Ave): No more Antioch University building and the foundations are being ripped up.

I am so intrigued to see how this excavation works.

Onni Connie Block 10/24/19

Activity has ramped up. Joining the lone small yellow thingy from yesterday are more thingies as well as what appears to be the makings of a large blue crane.

Sounds like they are starting as well. I found this letter in their SDCI files today:

Susan and Nancy,
As part of getting our permit issued for 2301 7th Ave we have been tasked with coordinating the interaction with the BB6 project (permit(s) noted above) and our project at the Alley. I understand that resolution of this will be a condition of some sort at our Preconstruction Meetings with SDCI and SDOT on October 8th and I assume it has also been communicated to BB6 that this coordination is required prior to proceeding with Shoring in the Alley.

Currently both projects are tracking a concurrent shoring and excavation and we are working on concepts for a post permit revision to allow for that. Before we expend too much effort we would like to request a Pre-Submittal meeting with Onni, our Shoring Engineer, our Structural Engineer, and our Shoring Subcontractor (Malcolm Drilling) along with the same group from the other project (HB/Concord, Ground Support, JTM, DBM) to discuss the feasibility, technical challenges, review timelines and process implications.

Both project teams have been working together in good faith over the last week to come up with a mutually beneficial solution that complies with our Reciprocal Tie Back agreement and what we believe addresses SDCI and SDOT concerns with each system as well as the active utilities in the alley.

We will be ready to present, in concept, this option with some preliminary engineering feasibility calculations and details the week of October 21st, 2019 with the goal of submitting and processing revisions in tandem prior to the Thanksgiving Holiday.

Please let me know if this Pre-Submittal Meeting can be scheduled so I can get all of the folks involved working toward this goal.

I believe that with true coordination with both parties and in partnership with SDCI and SDOT we can successfully execute on the technical design and construction aspects resulting in satisfactory outcome for all parties.

If you have any questions please feel to contact me directly.

10/28/2019 Update:

  • New construction toys + materials have arrived: a blue crawler crane, a drill and shoring steel.
  • The excavator has dug up the foundation along the Battery St perimeter so drilling can begin.
  • The pedestrian detour on the Battery St side is now protected from vehicle traffic, as my indirect supervisor was displeased with the previous set up (people were mixing with cars on Battery).

Looks like a Seattle Fire Dept rescue at this site today. Looks like someone fell down a shoring pile shaft if I’m reading the photos right.

That's a hell of a way to kick off construction. I'm glad he wasn't badly hurt, and I hope the rest of the project goes more smoothly.
