ACI Tilt-Up Technician study guide
ACI Tilt-Up Technician · Work through your exam, one topic at a time.
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 study guide has 5 sections and about 1,538 words.
01Planning, Layout, and Site Preparation
Panel layout starts with the elevation drawings, not the plan. Each panel elevation carries a mark, its length, height, thickness, opening sizes, reveal and chamfer pattern, and the location of every embedded item - lift inserts, brace inserts, weld plates, and bearing angles.
307 words, about 2 min02Forming and Panel Construction
Edge forms and bulkheads set the outline, thickness, and the location of joints and openings. Build them straight, plumb, and square; a panel 1/2 in.
304 words, about 2 min03Reinforcement, Embeds, and Inserts
Reinforcement follows the placing drawings: bar size, spacing, cover, lap lengths, and the added steel around openings, corners, and lift inserts. Chairs and bar supports hold the steel at the correct depth - the cover on the face that becomes the exterior is a durability requirement, not a preference.
278 words, about 1 min04Concrete Placement, Finishing, and Curing
The mix must suit tilt-up work: workable enough to consolidate around dense steel and inserts, while meeting the specified maximum aggregate size, slump, and air content. Place in lifts, consolidate with internal vibration without dragging the vibrator through the steel, and screed to the form elevations.
334 words, about 2 min05Lifting, Rigging, Erection, and Jobsite Safety
Before the crane arrives, confirm panel weight, center of gravity, insert capacity, rigging configuration, crane capacity at the actual working radius, and the brace layout. Match rigging to inserts, use a spreader beam where the geometry requires it, and remember that sling tension climbs steeply as the sling approaches horizontal.
