Photo Update #9 - Level 2 Construction
Editor's note: To document construction of the Bullitt Center, the Bullitt Foundation has enlisted the help of John Stamets as project photographer. In addition to a keen eye, John brings a sharp wit, art for storytelling and attention to minute detail, all of which he will combine into regular project updates that will be posted in this blog. Read more about John's background here.
I don't have another green story ready for you, so meanwhile here are some photos of the 2nd floor construction in the first two weeks of 2012 - before it started snowing on January 15.
As shown in the top photos, the floor was poured in a light rain on Jan 4. I'm told that the extra water from the sky does not affect the concrete mix itself, but it does result in a rough textured surface of the final product, as shown in the third photo taken Jan. 10.
This is not a problem at the Bullitt Center, because later - after the building has been enclosed - a radiant heating floor will be built on top of this slab. That will consist of a thermal insulating layer first, followed by the radiant heating loops. All of this will then be covered with a concrete topping layer with a smooth finish.
Meanwhile back in January, the next three photos show aspects of the formwork construction for the reinforced concrete walls.
The remaining photos emphasize the formwork for the columns.
