In New York, the slurry wall construction is well underway, and the Hudson Yards casing is almost fully excavated. Unfortunately, the camera there stopped updating, so I can’t provide snapshots of the latest activity. However, the HYCC-3 camera is able to see the project. Some of the first sections of rebar for the shaft walls are being assembled as well.
There’s now going to be Sunday construction activity, which should help accelerate the HYCC-3 project as well, with work on the waterproof lining and concrete formwork expected to occur during the daytime, along with some residual rock excavation.
And with the groundwater stabilization project, the cofferdam is slowly shifting towards the NYC shore, where the next section of ground will be reinforced and stabilized, and another set of barges is being used to remove abandoned piles left in the water.
Amtrak has recently announced that they are beginning preparation work for the activation of the new Portal Bridge. Additional trackage and turnouts are now being constructed which will help make the transition to the new bridge easier. The photos they released below show some new stuff they are currently doing. Looks like there will be tracks under the NJ Turnpike bridge too.
Good to see the progress being made on the Gateway Project.
I follow this Gateway project and applaud and support the great work these folks are doing to improve our infrastructure here in the US of A. However, I closely follow the latest and greatest worldwide regarding our built environment; and it must be said that the USA is lagging behind in all things construction related.
This is just one example of where construction technology is regarding bridge construction: and this is a perfect opportunity to look at the stark comparisons. I have also posted similar comparisons regarding the construction of buildings here in the USA compared to other countries.
I find this type of information helpful; and hope you will find this video enlightening and enjoyable.
A contractor wants to try and temporarily pause bidding for the new NEC viaduct because they want to take part in it and while they were one of the candidates shortlisted, a union representative was not included in the labor agreement. This would delay the start date for the viaduct that connects the NEC to the new tunnels.
The deck for the 3rd piece of Tonnelle Avenue’s bridge is complete. Work is now shifting to building the walls, with the last pieces being the anti-suicide fencing, which comes after the walls are cast.
I have yet to figure out what is going on here but they’re now pouring concrete on what looks like some kind of scaffolding structure. I wouldn’t doubt that this is for the TBMs which are still set to arrive early next year.
