um not on purpose. i need the trench to put the power in and data, but i needed a concrete slab over to appease the wife. now as for the pier foundations - you can gauge the size by the hole and hoping wont move. tomorrow the rest of the drainage will be dug leading to the lake

So is that big square hole for the pier?..it looks wide but kinda shallow..? Well probably looks deep enough but really wide..?

Ok here goes my feeble explanation

this means I will have the bearing pressure of roughly 4800 kg or 4.8 t . Looking into a footing suitable I decided on a broad load bearing footing that would repel water with force of mass acting on surrounding base and stabilize with area covered and distributed under the mount. this means that when swinging the mount around it should not produce momentum of the footing with any rocking even in dry periods when the clay shrinks. see here for soil type description

the dome structure to be held is well under a 1000kg so normal footings of 450 by 450 are needed so with wind loading a footing of 450x 600 is what I came up with being a simpleton so there will be three stirrups per side allowing the 200 x 50 x 3000 beams to be spaced at 500 centres. the outer beam structure is 200 x 75 x 3000 and no way connected to the pier.

being right on the swamp I think that it wont dry out so I am looking for stability with consistent mass of the pier

there will be a slight delay - while helping me empty the trailer full of stuff my son decided my hand was to be removed as well while he was shovelling. I still have the hand attached but it is a tad sore. I spend over an hour with it in a bucket of ice water.

was a painful way of removing over a 1100kg of material, council charged me 110.00 for the privilege.

ok put in coms and power cables and subsoil and buried them.

need to set up pier location now

placed drainage and pits now for 2/3rds of yard. then we got 35mm rain in 30min - what a mess.

DA had been approved for shed so that side of the project can now commence

thanks Al, and thanks for having the discussion we did this afternoon.

OK i am having a thought - right out of left field.

due to the presence of snakes, rabid insects and the crappy ground i am on i was thinking something unthinkable - pouring the whole dome slab as an integral pour, being over 6 tons or just on 2.5 cubic metres. the dome just bolts to the concrete? am i nuts?

progress report - have to complete the shed, the drainage, the clothes line path, the path to the shed and then the area near the observatory before i can do the observatory. that is the order dictated by SWMBO. she also doesn't like the backyard being a mess.

So i have buried a keepsake - the ugly birdbath that was in the backyard - sort of a talking point - the body under the slab

so have dug the path (thanks for the help Scott) and the drainage and the rubble pit are now done

Naaa!!! You're thinking of Stockton, capital of HexV Chromium release into the Newcastle community. Around Dave's way it's just a bit o' the old lead and cadmium - no problem!

Looking good Davo.
I can send up a few Greek statues for you to bury too, if you like.
