Two nearby news items – a shooting and a TBM (the T stands for tunnel)

July 9th, 2014 by Mike

Two press released arrived this afternoon. One is on a shooting nearby in Victory Heights. The other is the launch of Brenda – the Tunnel Boring Machine heading for the University District.

From Seattle Police:

Police are investigating after a man was wounded in a shooting in the Victory Heights neighborhood Wednesday afternoon following a dispute over an apparent drug debt.

Police responded to the 1700 block of Northeast 103rd Street, where they found the victim, who had been shot in the foot. Medics transported the man to Harborview Medical Center with non-life-threatening injuries.

At the scene, witnesses told officers two men had fled the scene in a black Lincoln Town Car. Police are now searching for the two men, described as a white male, 5’8, wearing a black tank top, and a white male, 6’0, wearing a blue dress shirt.

From Sound Transit:

The first of two tunnel boring machines that will dig new twin light rail tunnels from the Northgate neighborhood in Seattle to the University of Washington began mining today.

That would be Brenda. You can read more here.

Why's that lane closed by the freeway? (hint: Brenda's coming)

May 7th, 2014 by Mike

Contractors for Sound Transit this morning closed a lane near the popular Interstate 5 entrance off Northeast 80 Street to install monitoring equipment to check on Brenda as she tunnels her way south from the Maple Leaf Portal.

“As early as Wednesday, May 7, Sound Transit’s contractor will install equipment along the Northgate Link tunnel alignment to monitor vertical movement of utility pipes (water and sewer lines) for the Northgate Link Extension,” according to a release from Sound Transit.

The monitors, called Utility Settlement Points, are glued to the top of a utility pipe inside a cast iron cover and inserted below the surface of the road and will be in place throughout construction of the Northgate Link Extension. This work will be done throughout the month of May and will take 1 to 3 days to complete at each location.

• Installation of the monitors requires drilling into the concrete, removing ground material with a vacuum truck and attaching the monitor to the utility.

• The contractor will perform this work between 8 a.m. and 4 p.m. weekdays. No high impact work will occur until after 8 a.m. A vacuum truck makes a noise similar to a diesel engine running at high rpms.

There are five work locations:  [Read more →]

Welcome (and soon goodbye to) Brenda, our own Tunnel Boring Machine

April 28th, 2014 by Mike

Update: There is now a Sound Transit press release about this event here.

Brenda, the Tunnel Boring Machine that already bored a segment of the light rail tunnel from downtown to the University of Washington, is being given a send off this afternoon at the Maple Leaf Portal.

With speakers, ceremony and a smashed cider bottle, Brenda is on her way again from the portal across First Avenue Northeast from Silver Platters and SAS Shoes.

Two light rail tunnels will be drilled from this location to Sound Transit’s Roosevelt Station, on 12th Avenue Northeast near Northeast 65th Street.

Crow's eye view of the Maple Leaf Portal dig

March 14th, 2014 by Mike

A reader sent us this link to a construction cam atop the Maple Leaf Portal work site.

(Sometimes we can get it to work. Sometimes we can’t. Go figure.)

He also says First Avenue  Northeast at the site, which is currently one-way southbound, may not reopen in both directions as scheduled at the end of this month.

“The contractor just requested that they keep it one lane through May. (Sound Transit) hasn’t decided yet if they’re going to grant that yet, and part of that decision will be up to SDOT.”

A different reader, who clearly knows a lot more about the light rail project than we do, emailed the below last week.

Glossary (by editor):

TBM =  Tunnel Boring Machine (we think).

ST = Sound Transit.

Brenda = TBM named after a project manager’s wife, according to comments on an earlier post. Brenda is not Bertha, the whopping big TBM stuck on its way under downtown.

North Link = light rail that will run from Husky Stadium to Roosevelt Station to Northgate. It should reach Northgate in 2021.

Togo and Balto: From the same comments: “The two TBMs that are digging from UW to Capitol Hill were named Togo and Balto after famous Huskies – the four-legged kind.”

The fact sheet regarding tunneling in the North Link document archive notes that one TBM will be launched from Maple Leaf toward Roosevelt, where it will be trucked back to Maple Leaf for re-launch. Two TBMs will be launched from Roosevelt toward UW.

Brenda’s remnants are definitely at Maple Leaf, ST noted that in an earlier press release. Probably fitted with a new shield assembly and cutter head. I believe the original shield was left in place in the tunnel near the Paramount. I’m guessing Togo and Balto will likely be reused on the Roosevelt to UW segment, as that would be a cost effective move for the contractor and probably figured into their bid. Maybe rename them Brendaborg, Togoborg and Baltoborg. 🙂

Looking forward to this group trying to beat the ULINK bar for cost and schedule, but we shall see, hopefully no immovable objects stand in their way.
