Verified vs OSHA sources · 2026-10-05

29 CFR 1926.703

29 CFR 1926.703 governs formwork and shoring for cast-in-place concrete: formwork must be designed, fabricated, erected, supported, braced, and maintained so it can support without failure all vertical and lateral loads anticipated during the pour, with the drawings available at the jobsite and shoring erected and removed under a competent person's supervision.

What 29 CFR 1926.703 requires (plain English)

29 CFR 1926.703 governs the formwork, shoring, and reshoring used to hold cast-in-place concrete until it can support itself. Because a formwork failure during a pour drops tons of wet concrete and the workers on it, the standard requires the formwork system to be engineered for the loads it will actually carry.

Formwork must be designed, fabricated, erected, supported, braced, and maintained so it can support without failure all vertical and lateral loads that may reasonably be anticipated. Drawings or plans, including any revisions, for the jack layout, formwork, shoring, and reshoring must be available at the jobsite. Shoring and reshoring must be erected, supported, braced, and maintained under the supervision of a competent person, and not removed until the concrete has gained sufficient strength, confirmed under 1926.701, to support its own weight and any superimposed loads.

1926.703 works hand in hand with the general concrete standard (1926.701), which prohibits loading a structure before a qualified person confirms it can support the loads. Formwork and shoring are the temporary structure that carries the permanent one into existence, and their failure is among the most catastrophic events in concrete construction.

The regulatory text

“Formwork shall be designed, fabricated, erected, supported, braced and maintained so that it will be capable of supporting without failure all vertical and lateral loads that may reasonably be anticipated to be applied to the formwork.”

Common Formwork & Shoring violations

Deficiencies OSHA cites under 29 CFR 1926.703 include the ones below, in no particular order. Distinct deficiencies can be cited as separate items, and each serious item carries up to $16,550 (2026). Broader per-instance stacking exists but is a discretionary, case-by-case OSHA enforcement policy, not an automatic multiplier.

Formwork or shoring not capable of supporting the anticipated loads (1926.703(a)(1)).
No formwork, shoring, or reshoring drawings available at the jobsite (1926.703(a)(2)).
Shoring not erected or braced under a competent person's supervision (1926.703(b)).
Shoring removed before the concrete could support itself: 1926.703(e) / 1926.701(a).
Inadequate lateral bracing of the formwork system (1926.703(a)(1)).

Shoring must carry the full wet-concrete pour load, not just the cured slab

A fatal misconception is designing or judging shoring against the weight of the finished slab. During the pour, the shoring must carry the full weight of the wet concrete, the formwork, the workers, the equipment, and the lateral loads from placing and vibration: far more than the eventual self-supporting slab. 1926.703(a)(1) requires the formwork to support without failure all loads that may reasonably be anticipated, which is why it must be engineered, built to the drawings, braced, and overseen by a competent person, and why shoring stays in place until 1926.701's strength determination is met. Under-bracing or premature stripping is what causes formwork collapses.

What OSHA inspectors look for

A compliance officer looks for formwork and shoring drawings on site, checks that shoring is plumb, braced, and adequate for the load, that reshoring is not removed until the concrete can support itself, and that a competent person supervises the formwork and shoring. Missing drawings and inadequate bracing are classic findings.

Example: how a violation is cited

A crew pours an elevated slab on shoring that was under-braced and not built to the drawings; the formwork fails and the fresh concrete and workers fall. OSHA cites 1926.703(a)(1) because formwork must support all anticipated loads without failure, with willful classifications reaching $165,514.

Formwork & Shoring compliance checklist

Use this to evaluate your compliance with 29 CFR 1926.703. Each item is a key requirement OSHA may verify during an inspection.

Design formwork and shoring for the full anticipated vertical and lateral pour loads.
Keep the formwork, shoring, and reshoring drawings (with revisions) available on site.
Erect, brace, and maintain shoring under the supervision of a competent person.
Do not remove shoring until a qualified person confirms the concrete can support the loads (1926.701).
Inspect the formwork and shoring before and during the pour for movement or distress.
Coordinate reshoring so upper-level pours do not overload lower, still-curing slabs.

2026 penalties for 29 CFR 1926.703

Maximums set by 29 CFR 1903.15(d). 2026 amounts unchanged from 2025 (no CPI adjustment; OMB M-26-11). Not an increase. The 2025 OSHA penalty levels remain in effect for 2026; OSHA made no inflation adjustment for 2026. 29 CFR 1903.15 identifies January 15, 2025 as the effective reference for these amounts, while OSHA's public penalties page currently references penalties assessed after Jan. 15, 2026.

Violation type	Minimum	Maximum	When it applies
Serious	$1,085	$16,550	Substantial probability of death or serious physical harm.
Other-Than-Serious	$0	$16,550	Relates to safety/health but unlikely to cause death or serious harm.
Willful	$11,823	$165,514	Intentional, knowing, or voluntary disregard of the requirement.
Repeated	$4,256	$165,514	A substantially similar violation cited within the last 5 years.
Failure to Abate	None	$16,550/day	up to $16,550 per day; total capped at 30x the daily amount (FOM Ch.6)

Formwork citations follow shoring collapses and are high-gravity. Serious violations reach $16,550 and willful or repeat violations $165,514; inadequate bracing and missing drawings are the usual findings.

Maximums and the willful minimum are set by 29 CFR 1903.15(d); the serious and repeated minimums are OSHA policy floors from its annual penalty adjustment memo. OSHA applies gravity-based and size, good-faith and history reductions (FOM CPL 02-00-164 Ch.6). Estimates only, not legal advice.

The business case for Formwork & Shoring compliance

Formwork failure during a pour is one of the deadliest concrete-construction events: tons of wet concrete and the workers on it fall together in seconds. Designing the formwork and shoring to carry the full pour load, building it to the drawings, and having a competent person oversee it are what prevent these collapses.

Frequently asked questions about 29 CFR 1926.703

What does 1926.703 require for concrete formwork?

Under 1926.703(a)(1), formwork must be designed, fabricated, erected, supported, braced, and maintained so it can support without failure all vertical and lateral loads that may reasonably be anticipated during the pour. The formwork, shoring, and reshoring drawings must be available on site, and shoring must be erected and removed under a competent person's supervision.

When can concrete shoring be removed?

Only after the concrete has gained enough strength to support its own weight and any superimposed loads. Under 1926.703 and 1926.701(a), shoring may not be removed until the employer determines, based on a qualified person's information, that the structure can support the loads. Removing shoring too early is a leading cause of concrete collapses.

Why must formwork be designed for more than the finished slab weight?

Because during the pour the formwork and shoring carry far more than the eventual slab: the full weight of the wet concrete, the formwork itself, workers, equipment, and the lateral loads from placing and vibrating the concrete. 1926.703(a)(1) requires the system to support all anticipated loads without failure, so it must be engineered for the pour condition, not the cured structure.

Do formwork drawings have to be on the jobsite?

Yes. Under 1926.703(a)(2), drawings or plans, including all revisions, for the jack layout, formwork, shoring, and reshoring must be available at the jobsite. This lets the crew build the system as engineered and lets a competent person and OSHA verify that what was erected matches the design that was calculated to carry the loads.

Regulatory history of 29 CFR 1926.703

1926.703 is part of Part 1926 Subpart Q (concrete and masonry construction), substantially issued in 1988 after formwork-collapse disasters such as the 1973 Skyline Plaza and 1981 Harbour Cay collapses drove the need for engineered formwork and competent-person oversight. Its design-for-anticipated-loads requirement is the core defense against catastrophic shoring failures.
