Construction worker installing ventilation system in building under construction

A construction worker is standing on a stepladder installing a ceiling in a commercial building. He is wearing a white hard hat, glasses, gray overalls, and work gloves. He is using a wrench to attach the ceiling panels. The building is under construction, with exposed brick and concrete walls. The time of day is daytime. The lighting is bright. The mood is organic. This photo is perfect for projects centered on construction, industry, and commercial buildings.
