I mentioned back in September work had begun on the Stinson Municipal Airport Control Tower. That work continues and I am happy to follow up by saying that the building is now officially out of the ground.
The main body of the tower (designed by AJT Engineering) consists of a series of stacked precast concrete panels. These are cast at a plant east of town, shipped to the site and then hoisted by a crane into place. This type of construction isn't particularly unusual - many "big box" retail stores and warehouses are built with precast panels as well - but the technique is remarkable in that you go from a foundation to something that resembles a building in a remarkably short period of time.
There is still lots of work to go on the project (the "wings" we designed along with Work5hop are just beginning to be fabricated in Arizona) but it's always exciting to see a design starting to become real.
