After the Frosts, Concrete Pouring in Harpenden

Thursday was scheduled for the pouring of the concrete for the ground floor at the Jarvis Development in Harpenden, after the hiatus caused by recent unseasonably cold and frosty weather. I made myself known to James Blackie the site Manager and the Project Manager for the sub-contractor.
I arrived too late to catch the first mixer arriving, but not so late as to miss the pouring. There were many more trades on the site this time, and Sean Mooney, the Project Manager for Toureen Mangan (currently the main subcontractor on site) took me to see the extra step he was taking to ensure they could pour with impunity, he had sealed the area beneath with frost blankets and installed Calor gas Space heaters!

It was interesting to see a trident-style mini flame thrower being used to clear some of the snow that had accumulated in some parts of the shuttering, as well as some workmen using magnets to collect stray steel wiring from the same recesses.

The crane was also active transporting beams from their storage area to the next section to be shuttered, and all around were small groups intent on sawing timber, creating new shuttering and vibrating or smoothing out the concrete.

When possible Concrete Mixer lorries were exiting the site as the next was arriving to take its place, but there did seem to be some occasions when traffic delayed their arrival, which was a shame with such a tight schedule due to the cold spell returning soon.
