The Problem
Pours proceed with rebar misalignment, wrong mix design or incorrect forms — resulting in costly demolition.
Root Causes
- Rebar spacing not verified against drawings
- Mix design ticket not reviewed at delivery
- Slump / air content not tested per specification
Correct Procedure
- 1Verify rebar size, spacing and cover against drawings before pour
- 2Check mix design ticket for strength, slump, air, admixtures
- 3Perform slump and air content tests per specification
- 4Take cylinders per code (typically 4 per 100 cubic yards)
- 5Verify weather conditions are within spec (temperature, wind, rain)
Prevention Steps
- Superintendent walks the placement before the truck arrives
- Second person verifies critical dimensions at high-risk pours
