This continues the report from 7/15/09.
The formwork has been completed for a footing for the next section of the heat duct tunnel.
Construction staff, volunteers and workshop participants are mixing concrete for their first pour in this location.
Here we see the initial process of mixing the concrete and using a wheel barrow to transport the liquid material to a chute to be delivered down to the tunnel entrance.
The concrete flowing down the chute was gathered at the bottom into a wheelbarrow to be poured into the formwork.
The liquid material was evenly spread into the form and distributed using rakes and trowels.
Three yards of concrete were mixed in nine batches.
This report continues next week.
