The demolition company that imploded the Amway Arena Sunday morning could soon be facing a lawsuit.

During the implosion, a piece of debris struck a nearby spectator.

The only part left standing were the building’s four corners.

“Our goal was to demolish those in the next couple of days to the next couple of weeks," said Richard Zahn.

Zahn is CEO of ZMG Construction, which served as the demolition manager for the implosion.

The four columns are hollowed out concrete that were stairwells while the arena was operational.

During the implosion, they served an even greater purpose by protecting surrounding buildings.

“It became a barrier from a hydrostatic shock standpoint and also from a blast shock perspective," Zahn said.

However, the barrier wasn't enough to shield spectators from flying debris.

Orlando police said an 8-inch piece of steel rebar flew into a crowd of people and hit 33-year-old Eric Eliason in the leg.

Rebar is solid steel that’s normally used on a construction site to reinforce concrete.

“We're all group huddling around trying to figure out how and why that could've happened," Zahn said.

The group was standing about a block west of the arena at Parramore Avenue and Amelia Street.

Police took statements from Eliason and two other witnesses who saw the debris flying at them.

Authorities recovered the rebar from the scene. The president of Dykon Explosive Demolition Corporation confirmed it came from the arena.

Though police said Eliason's injuries were minor, he was taken to the hospital for treatment.

Dykon is paying Eliason's medical bills, but it's unknown if he plans to file suit.

“We setup a safety zone," Zahn said. "We had a great implosion. Everything went as planned and we'll let the insurance companies get involved if that's necessary.”

Meanwhile, crews are sifting through all the debris left over after the implosion.

Officials said it will take eight weeks to clear before the area is fully leveled out.
