Last 2011 Visit to Foresters

This is likely the last visit in 2011 to the Foresters Development in Harpenden, and there was occasional sunshine, but it had rained a good deal over the last few days, so it was extremely muddy.

I spent some time covering the connection being made to heavy duty three-phase electricity cabling immediately below the Site Office Portakabin. I was intrigued by the clever shear bolts used to ensure a sound electrical connection; the studs shear when the intended torque is reached. The individual phases are shrink-sealed with a semiconductor material to ensure there is no crosstalk between the individual phases, and a conducting shield is then wrapped around the joints and bonded at each end by jubilee clips, before being covered by an outer plastic cover that is itself sealed at each end. The cover has two ports into which a mastic is poured that encases the connections completely weather-sealing them.

Nearby another man is grinding several steel reinforcing rods that were protruding from the edges of the pit where the electrical work was being done.

Elsewhere I took shots that finally showed some of the buildings more clearly now that the scaffolding is down, and that interior finishing was going in, and the work that was nearing completion at the back of the site, on the curving pathway.
