This is how buildings fail. . . and it’s hidden inside the concrete. #1 — No concrete cover. Steel touching air or soil can rust and weaken the structure. Use proper cover. #2 — Short lap splice. If bars are too short, load transfer breaks. Use the correct lap length. #3 — Wrong spacing. Too wide reduces strength; too tight hurts concrete flow. The most dangerous mistakes are the ones you can’t see until cracks show up. Follow for real construction truths.
