In a previous post, I showed some construction work underway on a project I am involved with.  This involves building a long span concrete bridge and the first steps are drilling the shafts into which the concrete will be poured to form the base for the columns upon which the bridge will ultimately rest.  Watching this from a distance, you don’t quite get the scale of what is involved.  However, when on site, you really get close to the heavy machinery that is necessary for this type of project.  I thought I would share some shots of this serious gear since I was able to get access to it.
