Pavement marking
I spotted a couple of guys marking up the pavements around our office today. Presumably the road and pavements are going to be dug up and these guys mark all the subsurface cables and drains. The whole thing looked very cool. As though the pavement had been attacked by mathematically inclined graffiti artists. Apparently the colours represent the type and location of subsurface structures: blue for water, yellow for gas, red for electric. I have no idea what the orange or green are used for.Labels: graffiti, london, pavement marking
