A construction incident occurred on Monday, January 19, 2015 near downtown Cincinnati at approximately 10:30 p.m. when the center and east spans of a ramp bridge being demolished suddenly fell 15-20 feet onto southbound interstate I-75 south freeway, killing a foreman and injuring the excavator operator. At the time of the incident, concrete slab was being removed from the deck of the ramp as a part of the demolition of the Hopple Street Ramp Bridge. The demolition work began a day earlier but had to be stopped due to concerns about some steel girders lifting off their bearings. Work resumed after the remedial measures recommended by the engineers were carried out. Those measures proved inadequate, and the incident occurred.

On November 13, 2014 at approximately 10:30 a.m., a pedestrian bridge under construction at the Wake Technical Community College at the Northern Wake Campus, Raleigh, North Carolina, suddenly collapsed killing a worker. Four employees were injured. At the time of the collapse, concrete was being poured on the metal deck to provide the walking surface. A few hours later, another similar bridge, also under construction, within a block of the first incident, collapsed at approximately 12:30 a.m. in the middle of the following night. No one was injured in the second incident. No construction activities were going on during the second incident.

Suddenly, during the act, the metal apparatus supporting the performers plummeted to the floor. Two of the performers sustained critical injuries. In total, there were injuries to nine employees. This incident occurred because the carabiner used to support the performers failed due to being improperly loaded.

On March 25, 2014, two communication towers owned by Union Pacific Railroad (Railroad) collapsed in Blaine, KS, killing two workers. The project consisted of dismantling an older communication tower with all its appurtenances (e.g., antennas, dishes, coaxial cables, etc.). The older tower was located next to a recently constructed tower. At the time of the incident, a gin pole was being raised on the older tower to lower a 10 ft. diameter dish when the rigging of the gin pole suddenly failed causing the 60 ft. tall gin pole to plummet down, resulting in the collapse of both the towers. One employee was situated approximately 20 ft. below the top on the older 250 ft. high tower and was engaged in disconnecting the 10 ft. diameter dish and another employee was on the same tower approximately 80 ft. from the top. One worker died at the scene and the other was pronounced dead at the hospital. There were two additional employees at the site who were not injured.
