The slab pour last week was a great success. For drainage purposes, the two slabs were created to slope down towards the center of the heat duct tunnel floor in order to accommodate water flow.
This week, the volunteers, workshop participants and construction staff have already begun building the formwork for the heat duct tunnel wall. Snap ties were used to hold both sides of the forms together.
Pictures of the pour will be posted on the next report 8/26.
