I don't know if they're happy with kayaks getting that close to the work site, but it looks like that's a great way to get an up close view.

Anyone hear anything yet about crane installation timeline?

That's probably still a ways off. We will have sheeting and excavation next. May had to wait a month or two for a crane.

Muddy water - more pressure to keep the walls from caving in down below where the sleeve reaches.


Making sure it goes in just right


The chains will hold the cage while the concrete is poured, and set.

Case is wrapping up - sheet pile is arriving. (as BVic noted)

I assume they will be using basically the same technique to build the river wall and river walk as they did for WPW? So we can probaly go back and look at those photos to see what we have to look forward to for this guy?

Sept 1



Some assembly required




Striking water




All done - the gravel fill allows the caisson sleeve to be pulled and the area graded over for the next phase.

Can someone elaborate on the last picture above? Has concrete been poured already for that caisson location, why are they back filling it?

LouisVanDerWright Sep 5, 2017 3:03 PM

The metal tube you see is a temporary liner that is reusable. They sink that liner into the ground, lower in a permanent galvanized spiral tube shell, then lower in a rebar cage and pour the concrete. After that's done, they fill the top of the cage with gravel and pull the temporary liner that you see. The reason they fill it with gravel is to temporarily bury the cage so equipment can drive over that spot again once the temp liner is out. I think it also probably fills in the gap between the temporary liner and the permanent shell so that there is less risk of settlement once the liner is out. You don't want your foundation tipping out of plumb when you pull that liner out.

Yes the caisson is already poured - many feet of rebar sticking out from the top of the concrete. Generally the pour stops at the level of the mat or sleeper that the column will attach to. Looking at the sheet piles wer are talking 6' minimum digging.

Thank you for the education, and making it easily understandable for a simpleton like me. So essentially the mat is going to be poured several feet below the top of the temp. liner after all caisson work is completed?

Thanks again for the pics!

Yes, they dig the tops of the cages back out after they are all done with the foundations and tie them together with the mat.
