Architectural Technologist – Benchmarks

Benchmark next door to Ben Johnson pub

One of my first jobs in an Architectural practice was to look for the local benchmark for a job I was to spend the next year on, drawing and record keeping. It was the start of a week of surveying an old pub, in a market town and I had to go to the local council office and find the level of a mark on a prominent building, although the map showed the level, it took me a while to find it, clean it up ready to make that all important first back-sight of the whole building complex.

But I bet not many students or even technologists ever look for them these days, but You’ll see them if you look, mostly on prominent buildings, mostly carved in stone. The Wiki site has a reasonable explanation of benckmarks with a picture of a benchmark in what looks like a granite stone wall, the photo, I have used today, today is in the centre of Birmingham, it took ages to find but eventually I managed to locate not just one but several, see my Flickr site for the others.

The CPD here leads from understanding OS maps, through surveying, to stone masonry, and levels within the UK,  other countries also have similar systems, see Wiki site.
