The Metz (Schneiders site redevelopment)

[Darc]

Some one said slow….   With absolutely no idea what has actually happened up to this point in time.  There is two levels of parking on this site.   Roughly an 170,000sq per level.  And as of today there has been over 30,000 cubic meters of concrete placed. and yes this winter has been a little rough.

it’s been a tough winter.   

Slow ...

They are working flat-out 5 days a week, with all 3 cranes going. It is a big site. I suppose that the snow and cold have slowed things down a bit, but I wouldn't call it slow. They started in a huge, deep hole, and now they are rising above the hoardings. It is difficult to show the progress over the whole site in pictures now that things are above ground. Projects around the region that have risen faster are much smaller in footprint.

Nice photos, @Darc!

This also had some different geotechnical considerations compared to most projects in KW so it takes longer. The vast majority of projects in KW follow a process that generally goes shoring, excavate, raft slab, build up. This one for various reasons required additional work, so you had shoring, excavate, some sections had additional works after excavation (HCM came back and did more work), raft slab, build up. So it had a longer underground process than most buildings ontop of a massive floor plate.

In areas where bad soil is common (some areas of Hamilton for example) you tend to see longer underground processes like this where you have additional works after excavation. This can be to install caissons to transfer load to more competent soils instead of having incredibly expensive and deep excavations. You'll also sometimes see wick drains installed to speed up consolidation settlement, most structures are designed to have 25mm of settlement, however soil conditions (especially silts and clays) may not allow for that, it may be significantly worse. A wick drain allows for a shorter path for pore water to escape allowing for quicker consolidation of those soils.

KW is generally lucky enough to avoid having those types of situations but sometimes it still happens, in this case it was one of them.

Are those drone shots?

Are you the operator of the crane ?  Cool perspective if so ...
