Tilt-up construction casts concrete panels flat on site and then lifts them into vertical position as walls, and the person running that sequence - layout, forming, reinforcing, casting, lifting, bracing - carries responsibility for both schedule and safety. ACI lists a Tilt-Up Supervisor/Technician credential within its Construction/Specialist Programs, under the Tilt-Up Concrete Construction heading, among the more than 30 certification programs ACI offers. The ACI Tilt-Up Technician case studies are 5 cases and about 3,258 words.
