Abstract: At approximately 11:00 a.m. on June 4, 2004, Employee #1 was employed by a construction company contracted to rebuild the seawall at a hotel located on Harbor Drive in San Diego. The Employer designed a serious of cofferdams that would be pulled in tight against the sheet pile sea wall. Once connected to the sea wall, the employees would work in the cofferdams. A 5000-pound aluminum cofferdam was delivered to the employer's yard where it was to be lifted off the flatbed trailer with a link belt crane and set down on dunnage. Two fellow employees attached 20 ft long nylon web slings to welded pad eyes in the obtuse bend of the cofferdam. The pad eyes were below the center-of-gravity. A one and one-half come-along was then attached to a tapered flange located at the top rear backside of the cofferdam. When the cofferdam was lifted by a crane and set down on the dunnage, the end dunnage collapsed. The cofferdam was lifted back up. Employee #1 was underneath the suspended load restacking dunnage when the come-along came loose. The cofferdam tipped and fell backwards, crushing Employee #1's right leg. Employee #1 was hospitalized and his leg amputated.
