Most of the big distribution buildings- amazon, walmart, truck freight docks, etc. are tilt ups. The panels can be so much bigger when tilt up vs what they can haul. The only advantage to hauling is if they are pouring in a heated building in cold climates= year round work.

The large tilt up buildings it isn't unusual to see 150-200,000lbs panels. Lots of snatch blocks and bars. And you hope the imbeds are good.

Here's one we did a year ago, which is a fairly typical type of build. The largest panels went around 15tonne plus rigging. They go up first, then a large toe footing is poured at the bottom of the panels, then structural steel. Props come down, floor grade is prepped as the roof is going on, then by the time they pour the slab the building is covered and you can pour in any weather.

There can be some variations to this, but this is pretty typical for an industrial type building.

Generally the only times you see tilt up now are on dairy factories for the drier towers, and some small jobs.

The only reason it was done on the job I posted yesterday was that it was cheaper overall, but it's also taken significantly longerIMG_20210526_132819578_HDR.jpg IMG_20210525_103456059_HDR.jpg

The inventor of this building method was a engineer named David Lovel Smith, a delightful bloke who thought out side the square. His earlier invention was slip form concrete curbing. I had a little bit to do with him professionally in what seems a lifetime ago.

Million sq ft buildings are cheaper to cast on sight

Around here small buildings are 150 thousand sq ft at the moment there is not enough precast capacity in the southwest to keep up with Phoenix alone precast is to busy doing parking garages going up everywhere
