we need to adjust the heavy structure after erected on 12 one inch foundation bolts as spirit level is not OK?

Use a floating point, or gimbaled hydralic plates to adjust as needed. this is also a known Earthquake Resistant design.

find a shop, those things are bolted in pretty damn good, and require some pretty heavy duty tools to remove and install

I would go to a pro, so if it does mess up,  maybe it will be covered. But it sounds like you're not adjusting everything properly.

once you pick the correct arbor for the caliber and insert it into the muzzle attach the culminator to the arbor\nmake sure it is leveled AND AWAY YOU GO\ni am not aware of any height adjustment

Well, you didn't say whether you're building a building, a bridge, a trestle, a tower, or other structure.  But you could start with some general articles, like this Wikipedia article, which has links to specific sites which give some specifications.\n\nThe other link gets properties for different I-beam sizes--I presume you understand the terminology well enough to read the resulting tables.

My advice to you is to get a 'solid footing'  Don't 'pour' too much of your own ideas into the 'mix' Keep it on the 'level' and for heavens sake, don't 'gravel' they won't take you seriously.

need to know the mechanics of the lift you are proposing. Otherwise the answer is just 826 N.\n\nAre you worrying about compresive load? Tensile Load?  Which Joint?

I wouldn't attempt it unless you can level the ground. Trying to put blocks under the legs is a recipe for disaster.

it is weaker the higher you go

It sounds like a Civil Engineering problem, maybe for steel structures? Well, regardless, I suggest going to the ASCE (Am. Society of Civil Engineers) web site. They should have some good examples including some mesh - free finite element method solutions. Should give strengths, buckling info, etc.

Have you turned it over? If so try a piece of plywood underneath.  That should stop the sagging...it might be a little more firm though.  Otherwise...replace it!

I saw the first answer and i concur but you can also put Large Eye hooks in the walls and wire the rack to the wall. If an earthquake comes it won't fall over. Same with any upright furniture you have such as tall cabinets, etc....buy strong wire. Eye hooks are circled steel with a screw running out of it just in case you may not know. Good luck!

the needed papers/license to build something like that.\n\nThe construction should be checked also before building (strong enough etc)

Check with some local contractors or place your add with the local newspaper.  Good Luck!

Among the possibilities, the foundation could be affected by compression from the damp and unyielding surrounding soil.  Extra drainage gravel around entire foundation may minimize foundation pressure fissures/cracking/collapse.\n\nHigh water table may require continuous or nearly continuous pumping to prevent flooding of basement or lowest level of structure.\n\nSlab construction, if possible, would eliminate below grade issues.
