First update from this afternoon’s West Seattle Bridge Community Task Force meeting is the latest on Topic A – the repair work that’s about to begin. (That wasn’t the only topic discussed, but we’ll get to the others in a later report.) From the slide deck, the announcement that the Maximum Allowable Construction Cost (MACC) contract is almost ready to be signed:
Bridge program director Heather Marx said, “You will see Kraemer North America [repair contractor] crews back on the bridge this month,” first bringing equipment and materials onto the bridge. They’re building work platforms offsite. Much of the current work happens inside the bridge or off the bridge – but she said you will see work crews, trailers, and equipment. Also ahead: Hydroblasting to create lifting points for the work platforms; there are old ones from the stabilization process but they have to create new ones for the “tail spans” – sections of the bridge on which work was not done during the stabilization process.
There will be some “short-term” low bridge, street, and waterway closures for the platform installation, and they’re promising lots of advance notice. Here’s the timeline:
Carbon-reinforced polymer wrapping starts around the first of the year, and low-bridge work – including more of that – also starts in the first quarter.
“As soon as we sign the contract, we’ll be free to talk about when the work is expected to be done,” Marx promised. Asked later if that contract would be viewable post-signing, Marx said it’s a public document, so yes. But she also said the work is “risk-loaded”:
The work also could go “better” than planned, she noted. The activities mentioned in the slide above include a planned “celebration” for the community – but she promised that will not delay the reopening.
Also addressed at today’s meeting – the low bridge, recent West Marginal Way work, and the study for a bridge replacement that’s likely 40 years in the future (more from SDOT Blog here). We’ll get into all those details in a separate report later.
