Who can be held liable for construction accident injuries

Well, in a construction accident scenario, there could be potentially multiple liable parties. You could have the owner of the construction site. You could have one of the contractors. You could have another person there working. It really all depends on who performed the conduct that was negligent, or unreasonable under the circumstances.
It could also be the property owner, because they didn’t keep their property in a reasonably safe condition, so really the important thing is you get to an attorney. The attorney can sort out who was responsible for the harm that you sustained because of some negligent conduct, or because of something wrong with the property, that caused your injury.
