ACI Tilt-Up Supervisor study guide
ACI Tilt-Up Supervisor · Work through your exam, one topic at a time.
The ACI Tilt-Up Supervisor certification is a professional credential for field supervisors, superintendents, and crew leaders who run tilt-up concrete construction-casting panels on grade, lifting them into place, and bracing them safely. It signals that a supervisor understands the full sequence from site layout and casting-bed preparation through reinforcement and embed placement, concrete placement and curing, rigging and lifting design, erection, bracing, and the inspection and tolerance checks that close out a job. The ACI Tilt-Up Supervisor study guide has 9 sections and about 2,771 words.
01Tilt-Up Planning, Site Preparation, and Layout
Tilt-up planning starts with sequencing the site so that casting beds, crane paths, and panel storage never fight for the same ground. The candidate must understand the relationship between the construction joint plan, the crane location plan, and the panel casting layout: panels are cast as close to their final position as practical, and the crane must be able to reach each pick radius without repositioning mid-lift.
357 words, about 2 min02Foundations, Slabs-on-Grade, and Panel Casting Beds
This domain covers the ground and concrete surfaces that support both the finished building and the casting operation. Candidates must distinguish foundation elements (footings, grade beams, slab thickening under panels) from the casting bed itself, which may be the building slab, a temporary separate bed, or a combination.
315 words, about 2 min03Formwork, Edge Forms, and Panel Geometry
Edge forms define panel dimensions, reveal and rustication profiles, and the joint geometry between adjacent panels. Candidates must understand that tilt-up panels are typically cast in stacks or side by side, so edge forms serve double duty as separators and as the visible joint face.
317 words, about 2 min04Reinforcement, Embeds, Inserts, and Connection Hardware
Tilt-up panels carry reinforcement for structural capacity, shrinkage and temperature control, and lifting and bracing loads. Candidates must understand the difference between designed structural steel and the reinforcement added specifically for lifting inserts and brace anchors, and why the two must be coordinated.
308 words, about 2 min05Concrete Materials, Placement, Finishing, and Curing
Tilt-up concrete must meet strength requirements at the time of lifting, not just at 28 days. Candidates must understand mix design parameters - water-cementitious ratio, aggregate size, admixtures, and early-age strength gain - and how they interact with placement, finishing, and curing.
305 words, about 2 min06Lifting and Bracing Design, Rigging, and Hardware
This domain addresses the engineered side of lifting: insert design, rigging geometry, brace design, and hardware selection. Candidates must understand that lift inserts are designed for a specific load and load angle, and that rigging geometry changes the load in the insert and sling.
312 words, about 2 min07Panel Erection, Lifting Operations, and Bracing Installation
Erection is the highest-risk phase of tilt-up construction. Candidates must understand the sequence: lift planning, crane setup and verification, pick and set, temporary bracing installation, and release of the crane only after braces are secured.
296 words, about 1 min08Safety, Job Hazard Analysis, and Lift Planning
Safety in tilt-up is dominated by three hazards: struck-by and crushed-by during lifting, panel instability during erection, and falls during bracing and connection work. Candidates must understand the job hazard analysis process - identifying tasks, hazards, controls, and responsible parties - and how it feeds the lift plan.
294 words, about 1 min09Inspection, Tolerances, and Quality Assurance
Quality assurance in tilt-up spans pre-placement, placement, and post-erection inspection. Candidates must understand the inspection points: subgrade and bed preparation, form dimensions and squareness, reinforcement and embed location, concrete placement and curing, lift strength verification, and post-erection alignment.
