Week 41, Part 1

So this time we’ll take a concrete pad, a very small one, from beginning to end. Here Owens has carved out the dirt & gravel of our existing ground level, down to where structural gravel should be placed below a concrete pad for a large generator. This will be the emergency generator to run the plant during a power outage-



Using a laser and grade rod they set the gravel to the proper depth-



After it was rolled and tested for compaction, CNI laid out the corners with surveying equipment and built the forms. You can see the Mechanical building in the background. This generator will sit about 60’ north The electricians came in and stubbed-up their conduits which will receive the power lines from the generator. (This is not the finished form & rebar but gives you the general idea) -



Then we ordered 6 yards of concrete and a blue sky with white puffy clouds-



And, viola!- a generator pad, more complicated than you might think for a plain looking rectangle of concrete-



This week in the Mechanical building the taping crew wrapped up work. Here is the final phase in UV, sanding-



And they were sanding in the Belt Filter Press room as well-



The duct bank from Operations to Mechanical has extended over the past couple weeks. Here’s two ways of looking at it. The first looking mostly northeast towards Operations-



And here we’re looking west by southwest towards Mechanical-



More progress has been made lately on AeroMod control details. Much of the system is run on pneumatics so CNI pulled pneumatic lines out to the valves on the walls of the Treatment structure. AeroMod reps will finish the installation later-



This is the south wall of the Treatment structure. On top you see the end of one section of catwalk and a mud valve handle to the left of the railing. Down in the wall are the twin sludge draw-off pipes-



A close up of the sludge draw-off pipes. These will be tied into the “sludge line” and run underground over to the Belt/Filter Press room of the Mechanical building. This line enters through a pre-staged penetration in the foundation of that room. Below the floor there is a 90 degree bend and a pipe coming up through the floor waiting to tie into the Belt/Filter Press which is not installed yet. (Why? Because the taping crew is sanding there this week. There will be a quiz later- I assume you’re taking notes?!)-
