Paving the way

'I like work: it fascinates me. I can sit and look at it for hours.'
Jerome K. Jerome

A reasonably fascinating, and certainly photogenic bit of work that was going on as I was walking past on my lunch break - of course I didn't walk past but instead crossed the road for a closer look and then used the heras fencing as a kind of improvised tripod to get a clear shot or two.
