AI for rebar fabricators, tested on bid sets and placing drawings you already closed.

Estimating and detailing are separate crafts under one roof. CRSI's Manual of Standard Practice, in its 31st edition from 2024, gives estimating reinforcing materials and services one chapter and detailing the next. ACI 315R-18, the Guide to Presenting Reinforcing Steel Design Details, from a joint ACI and CRSI committee, draws a similar line in its definitions: a detailer produces fabrication details and placing drawings, and a fabricator produces the steel cut and bent to them. Both desks do their work on paper, ahead of the shear, which is what lets a test on old documents be fair.

Your closed work is the answer key. Every bid you priced has a quantity sheet behind it, and every placing set you issued has whatever came back from review. Your reviewer can score each draft against those records, member by member or mark by mark, with no live job at risk.

Bends have a published standard, and they stay on the shop floor. CRSI's IPG5.1-2026 covers bend diameters, measuring points and fabrication tolerances for steel reinforcing bars. A bar's shape comes to the test from the work your detailers already did. The draft reads what your drawings say and never tells the shop how to bend.

Public owners want paper with every load. An October 2011 appendix to Iowa DOT's materials instructions has suppliers and fabricators of epoxy coated steel that lack a coating line of their own approved before bidding on its projects, after explaining in writing how they keep heat numbers and inventory straight from arrival through shipment; coating plants holding CRSI's fabrication certification skip that step. Its identification report has columns for size, length, grade, heat number, coating lot, pieces and weight. Georgia's Standard Operating Procedure 26, revised in 2003, wants DOT Form 166 A for epoxy coated bars, with heat numbers, contractor and project number, within five days of shipment. That is why shipment packets sit third on this page.

Plant certification is a different audience. CRSI's Epoxy Bar Fabricator Certification looks at quality control, handling and storage, identification and coating repair, with an independent third party inspecting plants at random at least once a year, and CRSI publishes CG2.1-2026 for epoxy-coated bar fabrication facilities. None of that comes into this test, which reads documents and leaves the yard, the shear and the audit to your people.

One limit covers both jobs. Nothing here touches your detailing, estimating or production system or a live bid or drawing, and nothing decides what a design requires or approves a drawing. An estimator checks every quantity sheet, and your detailer and the engineer of record decide every conflict. Standards and agency rules are named so you can recognize them; nothing on this page is legal or engineering advice.
