This report continues from 09/18/09.
Last week, the construction crew worked on building formwork for the retaining wall on top of the heat duct tunnel roof.
For the concrete pour, a ramp was moved to a higher ledge so that it was leveled with the elevated scaffolding. Wheelbarrows of concrete were dumped directly into the wall.
1 yard of concrete was mixed to fill the wall.
Here we see the formwork taken off, revealing the new wall. While the concrete is left to cure, the construction crew will continue excavation for the footings for the next section of the heat duct tunnel.
We will continue to report as construction progresses.
