The temperature is really cold but our Builder is continuing to move forward. Today the plumber is on site to put in the under slab pipes and the sump pump. The ABS glue needs at least 7 deg C so lots of heat will be needed. Currently large electric heaters are running and propane heaters will be added.

Our Builder is hoping to pour the first floor slab next Monday, which he will confirm later this week. Once the slab has adequately cured he can start building the concrete ceiling forms according to the design that was done by the Structural Engineer.
