Formwork, Shoring, and Concrete Pour Collapse Claims

Who Is Liable When Formwork or Shoring Collapses During a Concrete Pour?

The property owner and the general contractor, before you get anywhere near the concrete subcontractor.

New York does not treat a shoring collapse as an accident that happened. It treats it as a failure to meet duties that are written down, measured in pounds per square foot, and in some cases required to carry a licensed engineer's seal.

A deck that comes down under wet concrete drops workers and tons of material at once. These are among the most severe injuries in construction and among the most provable, because the Industrial Code specifies what should have been there.

The question in most of these files is not whether a rule was broken. It is which rule, and who signed for it.

What Industrial Code § 23-2.2 Requires of Forms, Shores, and Reshores

Labor Law § 241(6) makes owners and contractors answerable for violations of the Industrial Code, but only where the provision relied on sets a concrete specification rather than a general reminder to be careful. Subpart 23-2.2 is one of the cleanest examples of a concrete specification in the entire code.^[1]

Structural Safety and Bracing

Forms, shores, and reshores must be structurally safe and must be properly braced or tied together so as to maintain position and shape. That is a result the code demands, not an effort it encourages. A deck that moved is a deck that did not maintain position.

Continuous Inspection During the Pour

The code requires designated persons to continuously inspect the stability of all forms, shores, and reshores, including braces and other supports, while concrete is being placed, and to remedy any unsafe condition immediately. This is the provision the defense least wants examined, because the answer is usually a name or the absence of one. Who was the designated person on that pour? What was he doing? Did anyone stop the pour when the deck started to move?

Bracing, Seating, and Mud Sills

Necessary horizontal and diagonal bracing must be provided in both longitudinal and transverse directions to give structural stability to beams, floors, and roofs. Shores and reshores must be properly seated top and bottom and secured in place. Where they rest on the ground, mud sills or other bases are required. Each of those is checkable against photographs taken after a collapse.

The 150 Pounds Per Square Foot Line

Where the sum of the dead and live loads on the forms may exceed 150 pounds per square foot, the design of the forms, including shores, reshores, and bracing, must be as specified by a professional engineer licensed to practice in the State of New York. Those design plans and specifications must be kept on the job site and available for examination, and everything must be constructed and installed in accordance with them.

This is the single most useful sentence in the Subpart. Most structural concrete decks in New York carry loads well past that threshold once the wet concrete, the reinforcing, the equipment, and the crew are counted. So the questions become documentary. Was there an engineered shoring design? Is it on site? Does the shoring as built match the drawing? Was it changed in the field without going back to the engineer?

Stripping and Reshoring

After stripping, forms must be promptly stockpiled or removed from areas where people work or pass, and protruding nails, wire ties, and other form accessories that are not needed for later work must be pulled, cut, or otherwise made safe. Reshoring must be provided where it is necessary to support slabs and beams safely after stripping, or where those members carry superimposed loads from construction on the levels above.

Premature stripping is its own recurring failure mode. A slab that has not cured to strength will not hold the load placed on it from above, and the collapse frequently happens a floor or two below where the work is going on.

Why a Collapse Is Usually Two Claims, Not One

A shoring failure ordinarily supports both statutory claims at once, and they are proved differently.

The § 241(6) Claim

This is the Industrial Code claim described above. It requires identifying the specific provision violated, and the worker's own comparative fault can reduce the recovery. Its strength is that the standard is written down and measurable.

The § 240(1) Claim

Where a worker falls with a collapsing deck, or is struck by material that falls because a shoring system failed, the injury is gravity doing the damage. That puts it inside Labor Law § 240(1), where the owner and general contractor carry an absolute, non-delegable duty and comparative negligence is not a defense at all.

A worker on a deck that drops is not in a close case on this point. Neither is a worker on a lower level struck by falling formwork or concrete. Our page on the Scaffold Law and how § 240(1) works covers the doctrine, and struck-by falling object claims covers the branch that applies to workers below.

Where the Two Come Apart

Not every concrete injury is elevation-related. A laborer hurt by a form panel that tipped over at grade, or cut by a protruding wire tie on stripped formwork stacked in a walkway, has a real § 241(6) claim and a weak § 240(1) one. Pleading both and letting the evidence sort it out is ordinary practice, and it is why the physical evidence matters so much in the first weeks.

How Formwork and Shoring Systems Actually Fail

Collapses repeat in a small number of patterns, and each one points at a different company.

Undershoring and Missing Reshores

Fewer posts than the design called for, posts pulled early to move material through, or reshoring skipped on the floors below an active pour. This is the most common single cause and it usually traces to field decisions rather than to the engineering.

Improper Seating and Eccentric Loading

Shores that are not plumb, that bear on debris or soft fill instead of a mud sill, or that land on a slab edge rather than over a beam line. A post carrying load off-center buckles at a fraction of its rated capacity.

Inadequate Lateral Bracing

Vertical capacity is rarely the failure. Shoring towers come down sideways, and the code specifically requires horizontal and diagonal bracing in both directions for exactly that reason.

Overloading the Deck

Concrete stockpiled in one location rather than spread, a pump truck boom placing load faster than the design assumed, or material and equipment staged on a freshly poured floor.

Premature Stripping

Forms removed before the concrete reached the strength the design required, frequently in cold weather when curing runs slower than the schedule assumes. Cylinder break test results and the concrete supplier's delivery tickets are the evidence.

Damaged and Mismatched Components

Bent frames, worn screw jacks, mixed manufacturers within a single tower, and rental equipment returned to service without inspection. The shoring supplier's inspection and rental records become central here.

The Evidence That Decides a Shoring Collapse Case

A collapse scene is cleared quickly, because the project cannot continue around it and the structure above it may be unstable. What survives is paper and photographs.

• The engineered shoring design. Sealed drawings, load calculations, and the specified layout, which the code requires to be kept on site.
• Pre-pour inspection and sign-off records. Whether anyone confirmed the shoring as built matched the design before concrete started moving.
• The identity of the designated inspector. Required by the code to be watching stability continuously during the placement.
• Concrete delivery tickets and cylinder break results. Volume, timing, mix, and the strength data that decides whether stripping was premature.
• Shoring rental and inspection records. What was supplied, its condition, and whether components were mismatched.
• Daily reports, foreman logs, and photographs. Frequently the only record of what the shoring looked like an hour before it failed.
• Any Department of Buildings or OSHA investigation. Independent findings assembled by people with subpoena power.

OSHA findings are worth a specific caution. A federal citation does not create a private claim in New York and cannot serve as the predicate for a § 241(6) claim, because the OSH Act expressly declines to enlarge or diminish state law rights. It is admissible as evidence of negligence, and that is a different and lesser thing. Our page on OSHA violations compared with the New York Industrial Code explains why the distinction changes case strategy.

Injuries From Deck Collapses and Falling Concrete

These events combine a fall from height with crushing under material, which is why the injury profile sits at the catastrophic end.

• Crush injuries and traumatic amputation. Wet concrete and formwork arrive together and do not move off a trapped limb without heavy equipment.
• Spinal cord injury and paralysis. From the fall, from the load landing on the back, or from both.
• Traumatic brain injury. Impact with formwork, rebar, or the level below.
• Multiple orthopedic trauma. Pelvic, femur, tibia, and calcaneal fractures characteristic of a vertical fall with load.
• Crush syndrome and internal organ injury. A distinct medical emergency in prolonged entrapment, with kidney consequences that outlast the initial trauma.
• Chemical burns. Wet concrete is caustic, and prolonged skin contact during entrapment causes full thickness burns that are frequently missed at the scene.
• Fatal injuries. Deck collapses kill more than one worker at a time more often than almost any other construction event.

What a New York Concrete Collapse Claim Can Recover

New York places no cap on compensatory damages, which matters in a category where injuries are frequently permanent and the future care number is the largest line in the case.

• Past and future medical expenses. Acute care, reconstructive surgery, rehabilitation, prosthetics, home modification, and attendant care projected across a lifetime.
• Lost earnings and lost earning capacity. For union members this includes benefit and pension contributions, not take-home pay alone.
• Pain and suffering. Ordinarily the largest component, and valued in New York against what appellate courts have sustained on comparable injuries rather than against a formula.
• Loss of enjoyment of life. A separate element under New York law.
• Future care, household services, and life care planning. Priced by professionals rather than estimated.
• Loss of consortium. A spouse's independent claim.
• Wrongful death and survival damages. Where the collapse is fatal, the estate can recover the decedent's conscious pain and suffering separately from the family's pecuniary loss.

Our page on the Labor Law claim running alongside workers' compensation covers how the two proceed together.

 

Why Concrete Crews Bring Collapse Cases to Lawsuit Legal

A shoring case is won or lost on whether the engineered design gets compared to what was actually built, and that comparison has to start before the site is rebuilt.

• A New York attorney and a New York office. Don Worley has been admitted in New York since 2005, with more than 20 years in personal injury practice. The firm's office at 305 Broadway sits in the Manhattan courthouse district.
• Verified Scaffold Law experience. New York Labor Law § 240 and § 241 work is a core part of the practice.
• Structural evidence preserved fast. Preservation demands for the shoring components, the sealed design, the pour records, and the cylinder break data.
• Engineers retained early. A collapse is reconstructed from load calculations and photographs, and that work does not wait for the defense to finish its own.
• Recognized trial lawyers. Our attorneys have been recognized by Best Lawyers in America, Super Lawyers, the Million Dollar Advocates Forum, and the National Trial Lawyers.
• A record built across 40,000 cases. Over $100 million recovered, a 98% recovery rate, and no fee unless we win.
