Drilling a Shaft

I was doing a visit to one of the construction sites that our team at work is managing currently.  There is a lot of elevated guideway as part of this project and that involves drilling shafts for the elevated structures.  The drilling was not underway at the location we stopped off at so I could see some of the drilling equipment.  Not only was the auger like drill on site but also the cylinders with cutting heads mounted on the edge which are rotated in place by the other tool next to the drill.  The crews can drill these holes at quite a rate when they are going and the result is that the structures are springing up across the project at this point.  Nice to be part of something that will be soon serving the communities in the south part of King County.
