well, steel is fucking out of control expensive right now, so go with concrete block an open web - if open web is the aesthetic you want.

how much is the tilt up - precast that they use for factories???

sounds like you need to do some local research on building systems.

where are you? prices change from place to place, sometimes wildly.

online, you can check with dodge/sweets. they even have a pricing calculator. this is a base test only, not ultimately all that accurate.

try to contact contractors in your area and check out similar jobs.

I'd agree with proto and betadinesutures. Compare the cost of materials and labor in your area for different building systems before making your decision.

Here's something else to bear in mind:
If your construction schedule and labor costs are the tightest part of your budget, a steel-framed building will likely be quicker to erect and enclose than a bearing-wall cmu-block building (of course it depends on the systems of enclosure, too). It may work out that, even if the materials are more expensive up front, you may save enough time and labor cost to justify the initial expense. Just a thought.

weeel... i think the nice thing about using block bearing wall is that it combines transfer of gravity loads, lateral loads and can be finished with a few coats of paint. the same could be said for precast 'sandwich' panels that have the same properites, PLUS its already insulated and theres a reduction in labor and construction time. a crane rental is a big expense, but i think at the end of the day its less expensive than cmu, especially if you're near the factory. open web joists WILL be less expensive then steel sections, and since you already have the rigger onsite, its a fast transition to putting up the roof structure.

sounds like time to call a couple of local contractors for advice....as has been noted, costs can vary widely from locality to locality, and sometimes a contractor has access to a supplier that will influence price for some reason...and climate/labor market can affect your decision also...tilt up used to be limited to texas/arizona/california, but lately I have seen it up here in Denver now more frequently, and it is a cheap, quick way to get a building up and enclosed....but, depending on where you are, the answer could vary on what is the least expensive for your project.

D4 cost Data systems: is a good software to use in developing preliminary cost estimates. It was designed for this purpose. They have in the past offered for use a sample version that you could try for up to three projects. The methode they use is a cost comparing of building types, and their cost. You will get a cost breakdown based on the CSI formatt covering all trdes and materials used on the project. I have fround it to be a good tool.You can find them on the internet.

Have a look at a beam( joist ) and Q-deck assembly. We are using a simple stragy to span a series of beam lines at 8' centers with 3" q-deck with all the insulation etc on the top side and exposed structure below. we are using parralams ( very industrial look, but you could use open web stuff or other. the walls are concrete block but depending on the overall size of the project maybe look at sips panels, precast walls and or tilt up. generally stealing from the light industrial warehouse asetheitc is where you'll get the most economy. Those prebuilt steel buildings are still the cheapest as the guys who build and design the stuff are wizards at reducing the steel content to its absolute min.
