Concrete and Formwork Accidents on NYC Construction Sites

Concrete work is a major part of construction throughout New York City. From high-rise foundations and apartment towers to sidewalks, parking structures, commercial buildings, and infrastructure projects, workers regularly build forms, install reinforcing steel, pour concrete, remove forms, and perform finishing work.

These jobs can become extremely dangerous when formwork fails, shoring is inadequate, reinforcing steel is left exposed, or workers are struck by concrete equipment and materials. A single structural failure can injure multiple workers at once.

Hill & Moin LLP represents construction workers injured throughout New York City. When a concrete or formwork accident occurs, investigating the design, installation, inspection, and removal of temporary structures can be essential to determining what happened and who may be responsible.

What Are Concrete and Formwork Accidents?

Formwork is a temporary or permanent mold used to hold freshly placed concrete until the material has gained enough strength to support itself and other expected loads.

Workers may install:

• Wall forms
• Column forms
• Slab forms
• Shoring systems
• Reshoring systems
• Vertical slip forms
• Concrete decks
• Reinforcing steel
• Temporary work platforms

These systems often carry tremendous loads.

Wet concrete is heavy. When concrete is poured into a form, the structure must withstand both vertical and lateral forces while workers, equipment, and materials may also be present.

OSHA requires formwork to be designed, fabricated, erected, supported, braced, and maintained so that it can support all reasonably anticipated vertical and lateral loads without failure. Formwork drawings, including revisions involving shoring, working decks, and scaffolds, must also be available at the jobsite.

How Do Formwork Collapses Happen?

Formwork collapses can happen suddenly.

One moment, workers may be standing on or beneath a concrete deck. The next, forms or supporting shores can give way under the weight of freshly placed concrete.

Possible contributing factors include:

• Improper formwork design
• Insufficient bracing
• Damaged shoring equipment
• Weak or unstable support surfaces
• Improperly positioned shores
• Excessive loading
• Concrete being placed too quickly
• Premature removal of forms
• Inadequate reshoring
• Failure to follow engineering drawings
• Alterations made without proper approval

OSHA requires shoring equipment to be inspected before erection. Erected shoring must also be inspected immediately before, during, and immediately after concrete placement. Equipment that has been weakened or damaged enough to reduce its required strength must be reinforced or removed from use as appropriate.

These inspection requirements reflect how quickly conditions can change during a concrete pour.

Why Is Fresh Concrete So Dangerous?

Concrete may look simple, but a large pour can place enormous pressure on temporary forms.

The greater the volume and depth of the concrete, the greater the load that formwork and shoring may need to support.

If one portion of a support system fails, loads can shift onto neighboring components.

That can create a progressive collapse.

Workers can then be:

• Buried under wet concrete
• Crushed by formwork
• Struck by lumber or metal
• Thrown from elevated decks
• Trapped beneath collapsed structures
• Hit by reinforcing steel
• Injured by concrete pumps or hoses

A formwork failure can therefore combine crush, fall, and struck-by hazards in a single incident.

What Safety Measures Apply to Formwork and Shoring?

Concrete construction requires careful planning.

OSHA maintains an entire construction subpart addressing concrete and masonry work, including requirements for equipment, cast-in-place concrete, precast concrete, lift-slab operations, and masonry construction.

Important formwork protections may include:

• Engineering plans
• Proper bracing
• Suitable shoring
• Equipment inspections
• Stable supporting surfaces
• Correct load placement
• Proper communication during concrete pours
• Restricting access to dangerous areas
• Timely reshoring
• Waiting until concrete has sufficient strength before removing forms

OSHA specifically prohibits removal of most forms and shores until an employer determines that the concrete has gained enough strength to support its own weight and other loads. That determination must be based on applicable plans and specifications or appropriate concrete strength testing.

Concrete Hazard	Possible Failure	Potential Injury
Improperly braced formwork	Form collapse	Crushing or fatal injuries
Damaged shores	Structural failure	Multiple traumatic injuries
Early form removal	Concrete or deck collapse	Falls and crush injuries
Exposed reinforcing steel	Impalement	Severe internal injury
Concrete pump equipment	Struck-by accident	Head or orthopedic injury
Elevated work deck	Worker fall	Brain or spinal injury

The specific cause of a concrete accident often requires an engineering and safety investigation.

What Are Shoring and Reshoring Accidents?

Shoring temporarily supports concrete formwork while concrete cures.

Reshoring may be installed as original forms and shores are removed so that the structure continues to receive necessary support.

OSHA requires reshoring when concrete must support loads greater than its capacity after original forms or shores are removed. Reshoring cannot itself be removed until the supported concrete is strong enough to carry its own weight and all other loads placed upon it.

Problems may arise when:

• Shores are removed too early
• Reshores are improperly positioned
• Support systems are overloaded
• Damaged equipment remains in use
• Workers alter supports without authorization
• Loads are added before concrete has cured adequately

On a multi-story NYC building, a failure on one floor may also affect floors below.

You deserve a law firm that prioritizes your safety and recovery. If you were injured during a concrete pour, formwork collapse, or shoring accident, Hill & Moin LLP can investigate how the system was designed and whether required inspections and safety measures were followed.

How Can Reinforcing Steel Cause Serious Injuries?

Reinforcing steel, commonly called rebar, strengthens concrete structures.

Before concrete is placed, vertical reinforcing bars may extend upward from slabs, columns, or walls.

A worker who falls onto exposed rebar can suffer a devastating impalement injury.

OSHA’s concrete construction requirements address reinforcing steel hazards, and OSHA construction guidance specifically identifies unguarded protruding rebar as an impalement danger.

Rebar can also cause injuries when:

• Reinforcing assemblies collapse
• Bundles shift during hoisting
• Workers trip over horizontal steel
• Workers are cut by sharp ends
• Steel cages overturn

OSHA requires reinforcing steel for walls, piers, columns, and similar vertical structures to be adequately supported to prevent overturning or collapse.

What Happens When Formwork Is Removed Too Early?

Concrete needs time to develop sufficient strength.

Removing forms or shores before the concrete can support required loads can result in cracking, partial structural failure, or collapse.

This risk may increase when project schedules are aggressive.

Workers should not be exposed to structural hazards simply because a project is under pressure to move to the next construction phase.

An investigation after a collapse may examine:

• Concrete test results
• Pour dates
• Cure times
• Engineering specifications
• Formwork removal records
• Shoring plans
• Inspection documentation
• Project schedules

Concrete strength records can become particularly important in determining whether removal occurred prematurely.

Can Workers Be Injured During a Concrete Pour Even Without a Collapse?

Yes.

Many concrete accidents involve equipment rather than structural failure.

Workers may be injured by:

• Concrete pump booms
• Pressurized hoses
• Mixer trucks
• Buckets
• Conveyors
• Crane-suspended loads
• Vibrators
• Power screeds

A concrete hose can move violently if pressure changes unexpectedly or a blockage clears.

Workers may also be struck by moving equipment while concentrating on finishing or placing concrete.

On crowded New York City jobsites, coordination between concrete crews, crane operators, truck drivers, laborers, and other trades can be critical.

What Injuries Can Concrete Accidents Cause?

Concrete and formwork accidents can cause catastrophic injuries, including:

• Traumatic brain injuries
• Spinal cord injuries
• Crush injuries
• Broken bones
• Pelvic fractures
• Amputations
• Impalement injuries
• Internal bleeding
• Organ damage
• Nerve injuries
• Severe lacerations
• Chemical burns
• Eye injuries

Wet concrete can also cause skin and chemical injuries.

Workers who remain in contact with wet cement may develop serious burns because cement is alkaline.

A worker may not initially realize how severe the exposure is, making prompt washing and medical evaluation important.

Can New York Labor Law Apply to a Concrete or Formwork Accident?

Potentially.

New York Labor Law can provide important protections to qualifying construction workers injured because of unsafe site conditions or inadequate safety equipment.

Labor Law Section 241(6) may apply when a sufficiently specific New York Industrial Code provision is violated during covered construction, excavation, or demolition work and that violation contributes to an injury.

Labor Law Section 240(1) may also become relevant when the accident involves qualifying elevation-related risks.

For example, a worker may fall from a formwork deck because adequate fall protection was not provided, or a worker below may be struck by material that falls from an elevated location.

Labor Law Section 200 may also arise depending on whether the accident involved an unsafe work condition or work method and the relevant party’s level of control or notice.

These statutes are highly fact-specific, so the accident should be evaluated based on exactly how the injury occurred.

Who May Be Responsible for a Formwork Accident?

Potentially responsible parties may include:

• Property owners
• General contractors
• Construction managers
• Concrete subcontractors
• Formwork contractors
• Engineering companies
• Shoring contractors
• Equipment suppliers
• Equipment manufacturers

Responsibility can depend on who designed the formwork, who erected it, who inspected it, who supervised the pour, and who authorized removal of the forms or shores.

For example, if a damaged shore is discovered but concrete placement continues anyway, investigators may need to determine who knew about the defect and who had authority over the pour.

Don’t wait—your future starts with one phone call. Hill & Moin can investigate the contractors, engineering records, concrete testing, and worksite evidence surrounding a serious formwork accident.

What Evidence Is Important After a Concrete Accident?

A concrete accident scene can change rapidly.

Emergency stabilization may begin immediately after a collapse.

Debris may be removed, shores may be replaced, and damaged components may be discarded.

Potentially important evidence includes:

• Formwork plans
• Engineering drawings
• Shoring and reshoring plans
• Concrete strength test results
• Inspection reports
• Photographs
• Videos
• Surveillance footage
• Daily job logs
• Pour schedules
• Witness statements
• Equipment records
• Contractor agreements
• Safety meeting records
• Accident reports

OSHA requires formwork and shoring plans, including revisions, to be available at the jobsite, which can make those records particularly significant in an investigation.

What Should You Do After a Concrete or Formwork Accident?

Your health should be the immediate priority.

When possible, consider these steps:

1. Seek emergency medical attention.
2. Report the accident promptly.
3. Identify witnesses.
4. Photograph the work area if it is safe to do so.
5. Document the formwork, shores, equipment, and surrounding conditions.
6. Keep medical and employment records.
7. Preserve communications concerning the pour or safety concerns.
8. Write down what happened while your memory is fresh.
9. Speak with a New York construction accident attorney.

Do not enter an unstable collapse area to obtain evidence.

Personal safety must come first.

Can Workers’ Compensation Cover Concrete Construction Injuries?

Many employees injured while performing construction work in New York may qualify for workers’ compensation benefits.

Depending on the injury, benefits may include medical treatment and wage-related payments while the worker is unable to perform the job.

Workers’ compensation may be available regardless of whether a coworker or employer was negligent.

A separate third-party personal injury claim may also be available if another contractor, property owner, equipment company, or other responsible party contributed to the accident.

Because concrete projects involve multiple entities, both types of claims should be evaluated independently.

Frequently Asked Questions About Concrete and Formwork Accidents

What if the formwork suddenly collapsed with no warning?

A sudden collapse does not necessarily mean the cause cannot be determined.

Engineers may examine the design, loading, bracing, shoring, concrete placement rate, equipment condition, and inspection history to identify why the failure happened.

What if another subcontractor built the forms?

That may be important.

Your employer and the formwork contractor may be different companies. Depending on the facts, the contractor responsible for creating or maintaining the dangerous condition may need to be investigated separately.

What if I was injured while removing forms?

Form removal is itself a potentially hazardous stage.

OSHA requires most forms and shores to remain in place until the concrete has developed sufficient strength to support anticipated loads.

Can I have a claim if falling concrete hit me?

Potentially.

Investigators may examine how the material became loose, whether workers below should have been excluded from the area, whether overhead protection was appropriate, and which parties controlled the work.
