Week 77 (26th course all around)

In construction photos by Michael Tiemann

The focus of the past week has been on building up the inner wythe, which now reaches the 26th course all the way around, one course shy of the top of the 2nd diffusor pattern.  Here’s what it looks like now:


And here’s the side you won’t see:


Construction progress takes a lot of material, and it’s clear that some material was depleted and had to be refilled, like our steel rebar:


Others, like our mortar sand continues to dwindle:


And our ladder wire:


And especially our 12″ RPG blocks (which, with one course to go, will finish without being replenished):


In the coming two weeks we should see the outer wythes catch up (lots of grouting), and the window frames put into place for the final bond beam at the top of the room.  That will be a great accomplishment!
