A lot of progress was made between Wednesday and Friday this week, with some long hours put in. We are getting ready to pour our concrete foundations, with high hopes that it can happen Monday morning. Obviously there were a few snags in the process, like pieces of prefabricated steel rebar not fitting exactly right, or digging up utilities. The students have been assured that these are both very normal setbacks for any project. The rebar we laid will be inspected by both the City of Boulder and the concrete company, and if we did it right then we can pour concrete.
The product of Wednesday’s work. We got most of the space for the foundation dug out.
We checked on the hole for concrete bench. At 40″ below grade it was filled with groundwater, which means that we need to rethink how this can be accomplished. But it also proves that groundwater can keep the lake at its current levels!
Setting up formwork for the concrete. It is basically a frame. The concrete is poured in, hardens, then the forms are taken off.
Laying rebar. It provides structure for the concrete that will be poured over and around it.
A rebar grid that will be underneath a concrete pad leading from the sidewalk to the deck.
