? To continue our heat duct tunnel report from February 15th:

The forms were removed after the recent large pour. Workshop participant Cara Pirello and construction crew member Jeff Buderer transport the wood panels from the project site.


? A wider view shows the concrete of the outer wall after form removal and workshop participant Kirsten Lynge assisting with the project.


? The interior walls of the tunnel were painted black with a concrete pigment. This will help to generate heat after the tunnel roof is enclosed with a membrane. Pictured here are Dave Tollas and Cara working to complete the painting.


? Now, the heat duct tunnel interior walls are black. The floor painting is in progress and will be finished in the near future. Another upcoming construction step is to insulate the left wall pictured and backfill to help prevent heat loss.
