Our house backs onto a main thoroughfare, and the fence was becoming an eyesore. It was original to the subdivision about 20 years ago and wasn't holding up well. So the town decided that it needed replacing — at the owners' expense, but I will resist getting into the politics and minutia of it all.
I took a few photos of the work in progress. First, they drill the post holes.
After the drilling it takes manual labour to empty the the holes properly.
The posts are lined up and ready to be ... um ... posted? These posts, whatever they're made of, are rock solid and should withstand the elements for a long time.
The cement truck delivers its payload post by post.
And so it goes as the workers fill the holes and place the posts.
