A large milestone was completed this week in the construction of the waste water treatment plant (WWTP) building. The last internal slab was poured, bringing much joy to Mark (Junior — see image at bottom of page). The team have the apron at the front of the panel lift door and a small pad outside the rear stairs, and that will be the concreting done for the season. Including the apron in the total, the slabs have consumed 115 x 1800 kg batches of concrete. To make this amount, we needed to add 17,365 L of water heated to 60°C, along with 1.25 L of Visco plasticiser additive and 500 mls of AEA in each batch.
The WWTP has a large amount of equipment to be installed over the next year. To help facilitate the installation and future maintenance, an overhead gantry crane had to be installed. Some of our tradespeople are also qualified as riggers and dogmen — with their expertise the job was done safely and efficiently.
While waiting for the cut in of work on the new heating hot water pipe to happen, the project plumbers have been busying themselves with the installation of the new fuel pipe system. Last week a culvert was dug between the green store and the fuel tank for the vehicle refill point. The crew got the pipe in the culvert and up the wall of the building. Also completed was the fuel pipe in the culvert out the back of the tank house that will eventually hook up to the tarn building (where we make our water) and the new emergency powerhouse (one of the future stages of the WWTP build).
The fit out of the new asbestos demolition works decontamination container continues this week with a sub-floor installation, allowing for plumbing connections and drains to be built. The team will be able to shower on site, which minimises risks of working with asbestos. This gave Ken, our project engineering services supervisor, a chance for a much needed (and wanted!) break from the computer for a while.
