Today they poured the concrete for the basement walls. A pump truck was used to get the contrete where it needed to go because our site is so small and there are houses on each side of us. This picture shows the cement truck pouring the concrete into the pump truck. The long arm is the chute coming from the pump truck. Now that the concrete is poured, it takes about two weeks for the concrete to cure before they can lay the Spancrete.
Next week, they will be setting the steel for the columns, working on the under-floor electrical, and the piping for the HVAC (the library will have radiant heat). Then the basement floor will be poured.
On December 3rd and 4th, the spancrete was laid. The site has been partially backfilled. The waterproofing and backfilling should be done this week. (See picture to the left) Today they started laying the forms for the above grade walls. The above grade walls should take about 10 days to form and pour. The above grade walls, like the basement walls will be made of insulated concrete forms or ICF. ICF is a very energy efficient and 
environmentally friendly construction method. The picture to the right shows workers putting the forms together. For more information on ICF, go to www.forms.org
