Foundations

My son was asking about foundations last night, we got on to the subject of big buildings and I told him I'd take a photo to show him what they do.
Which reminded me that I was going to blog some pics of the building site across the road from the office.
Here's a nice view of work going on on the foundations, the blue machine on the right is drilling holes which get filled with concrete, and the reinforcing steel you can see near the back.
