I’m a custom home builder in Colorado and I always ignore the note on my structural drawings either brace the concrete foundation walls or install the floor framing prior to backfilling. As does every other builder I have ever seen here since installing the floor framing prior to backfilling would be challenging and framing crews would likely reject those conditions. I’ve looked at using tilt-up concrete braces but they are extremely expensive, about $500 each for a 5′ – 8′ brace. I’m thinking of using some steel “L” brackets to temporarily install some 2 X 10’s with 45’s cut on each end. 

Does anyone brace their walls before backfilling? If so, how?

Thanks.
