@habtamudagne: Changing rebar using only an equivalent steel area calculation is not enough. ⚠️ Equivalent formulas match the steel area (As), but they do not automatically guarantee proper spacing, crack control, lap length, development length, constructability, or code compliance. Always get approval from the Structural Engineer before changing any reinforcement on site. 🏗️ Build Safe. Build Smart. #ByHabtamuDagne #Construction #Rebar #Reinforcement #StructuralEngineering
