In some circumstances, the injured person will be able to recover damages from the construction company, which has a duty to take reasonable steps to keep public sidewalks near its construction site free from bricks and other debris. If the company fails to remove such obstructions and someone trips and falls, the company may be liable. Construction companies should also tell pedestrians they could get injured if they stray from the sidewalk. Posting a sign is usually not enough. If a company fails to place barriers and warning lamps by a building pit, for example, it may be responsible if anyone falls into it and gets injured.
