Injured by a Subcontractor on a Construction Job Site: Can You File a Third-Party Injury Claim?

Illinois and Indiana: Construction Worker Civil Injury Claims After Hurt in Subcontractor Accident

All sorts of construction projects are moving forward in our part of the country right now, employing thousands of workers in various trades. The current construction industries of Illinois and Indiana focus not only upon residential and commercial but are committed to big mixed-use; industrial; and heavy civil undertakings. See, “What are the Different Types of Construction?” written and published by ServPro on August 31, 2026.

For instance, there is the enormous residential construction “megadevelopment” on Chicago’s West Side, known as “The 1901 Project,” and there is the current Meta Lebanon Campus in Indiana heralded as one of the region’s largest industrial and heavy civil construction projects with a budget at $10 Billion to complete. See, “AI is driving a data-center power boom. Here are some of the biggest US projects being built,” written by Tristin Hoffman and published by Business Insider on September 29, 2026. Also see, INDOT Major Projects published online by the Indiana Department of Transportation.

For safety agencies, government regulators, and advocates for work accident victims and their families, the reality of all this construction activity comes with serious concerns about safety and protecting construction workers from harm in one of the most notoriously dangerous industries in the world.

Sadly, people working in construction in Indiana and Illinois are going to be involved in what are usually determined to be preventable accidents, suffering catastrophic bodily injuries or even dying as a result.

See, The 2025 OSHA Top Ten List of Most Frequently Cited Workplace Safety Standards: Warning to Workers.

For these construction worker victims, it is vital to understand that they may well have rights not just to file for workers’ compensation benefits under the policy legally required to be maintained by their employer, but to pursue legal claims for civil damages against various third parties for their redress.

What is a Third-Party Workplace Injury Claim?

Under the state law of Illinois and Indiana, construction workers may be able to file a personal injury lawsuit against either a person or a business that is not their employer, but whose negligent actions or omissions directly caused or contributed to the workplace injury. This is a “third-party claim” or “third party cause of action.”

A third-party claim is a civil personal injury lawsuit filed by the construction worker victim. Under the state laws of Illinois and Indiana, the worker will have the legal burden of proving with admissible evidence both their damages (think medical expenses, etc.) as well as the liability of the parties (how they are liable under the facts of the case).

Third party claims are independent of workers’ compensation claims. They proceed in different arenas. No choice must be made between the two. The third-party claim(s) proceeds in the civil court system. The workers’ compensation claim for benefits follows the statutory guidelines of the state and is overseen by the state’s workers’ compensation administrative system (either the Illinois Workers’ Compensation Commission or the Worker’s Compensation Board of Indiana.)

It is also common in these work accident civil cases for there to be more than one third-party who is sued as a “defendant” by the construction worker victim. The law does not prevent these multi-party claims.

Work Accident Civil Claims for Damages: Construction Subcontractors

Experienced construction workers are well acquainted with the flurry of activity on a project’s jobsite and they understand there are often employees of lots of different subcontractors at work all at the same time. Construction sites, no matter whether industrial, heavy civil, commercial, residential, or mixed-use, are recognized as “multi-employer” sites within industrial standards as well as federal regulations overseen by the Occupational Safety and Health Administration {“OSHA”).

Amidst all this hullabaloo, trades working for various subcontractors overlap not just in workspaces, but in the need to use heavy equipment and machinery; power tools; electrical and other power sources; traffic routes for people as well as vehicles (think forklifts); scaffolds; and more. It is usually crowded and loud.

If anyone working for one subcontractor fails in a duty of safety and care on these jobsites, there can be horrific accidents. Construction workers with paychecks signed by various entities can all be seriously injured in an instant because they were placed in jeopardy by the negligence of that subcontracting worker or due to a failure of something within the possession, custody, or control of that subcontractor.

Examples include:

1. Subcontractors for Demolition & Excavation

General contractors and project managers may rely upon specialized subcontractors to take care of the demolition and excavation that has to be done to clear the space. Duties of care and safety here cover not only doing things like making sure to understand the location of all the underground utilities, but to properly set up any trenches, and handle any explosive or other needs in excavation.

2. Subcontractors for Electrical Needs

Electrical power is needed on every construction site. Some of this is temporarily set up for things like power tools. Other electricity needs involve the planning of placement of permanent electrical sources (think breaker boxes, etc.). Electrical subcontractors have legal duties to protect themselves as well as all those on the site from injury due to things like live wires; bad insulation; etc.

3. Subcontractors Operating Heavy Machinery and Equipment

On many of the complex construction sites here in Illinois and Indiana, massive machinery and equipment will be mandatory. Subcontractors here will have employees who are licensed and adept at doing things like operating tower cranes or earthmovers. If they fail in their duties, think moving through a blind spot, or if the subcontractor fails in repair, inspection, or maintenance of its machinery or equipment, then horrific accidents (think struck-by or crushing) can happen.

4. Subcontractors Responsible for Staging

Subcontractors can also handle the staging of the construction site, doing things within their expertise like setting up scaffolds or platforms, and making sure there are regulatorily required things like guardrails and walk spaces. The failures of these subcontractor involving either their workers or their materials can form the basis of a negligence claim after a serious construction work accident.

Legal Claims for Damages After Construction Subcontractor Accident in Illinois or Indiana

There are an amazing amount of safety laws and regulations, as well as industrial standards, that define and explain in great detail the care and safety precautions that the subcontractors need to do in order to protect against a construction site accident. For more, read Construction Work Accident Injury Claims and OSHA Regulations.

If these regulations, statutes, or standards are not followed and someone gets hurt, then they can be used by the construction worker victim to define how a duty was breached that caused their harm. It is important for the injured and their loved ones to understand that the wrongdoers have no legal responsibility to come forward and admit what has happened. They can know they did wrong and say nothing regarding that civil injury claim, and it is not illegal for them to do so.

It is, instead, the legal duty of the claimant (the worker victim) to prove their personal injury claim with admissible documents, witness statements, etc., by a preponderance of the evidence. This involves investigation of the construction site accident with the help of accident reconstruction experts in construction matters and the legal analysis of the matter by legal advocates researching and applying the appropriate state law.

And there is a deadline placed by law upon the construction worker victim to do so. Any legal claim that is not filed within a set time period will be barred as a matter of law no matter how meritorious. Read, Deadlines for Injury Victims to File Lawsuits: Statutes of Limitations.

Construction workers in Illinois and Indiana have chosen a very dangerous line of work. No matter the size or scope of the construction project, there is a constant risk of being severely hurt. All too often, these injured workers will discover that their harm has been the result of a failure to protect them against a known hazard by a subcontractor on the jobsite.

Construction work is dangerous. Workers that are hurt need to know they can file for worker’s compensation and independently pursue civil personal injury claims under state law, which often involve problems with a site subcontractor over which they had no control. Please be careful out there!
