The concrete support pillar and footing formwork is ready to take some concrete

I have designed the formwork so that I can do it all in one pour, ie filling the footing space first, through those two side access holes in the cover board, then after blocking these access holes, fill the formatube (resulting in a sturdy monolithic one piece support pier) Then finally, press the anchor bolts into the wet cement, sighting on my true south stake, positioned accurately in the distance

I used this same approach back in 2014 for my last telescope pier and that worked a treat
