You generally have a construction accident case if a third party did something negligent, and their negligence caused you harm. Negligence is typically not an intentional act, but an act that a reasonable person would not engage in. The California Labor Code notes several measures that parties can take to avoid construction accidents. While many of these measures pertain to employers, they may also apply to third parties that may be defendants in lawsuits. We will compare the events that led to your accident to “reasonable” standards. If someone put you in harm’s way because they acted negligently (or failed to take precautionary measures), you can sue them for the damages you’ve suffered.
