The Top 5 Building Demolition Failures

Building Demolitions Don't Always Go According to Plan; In Some Cases, Explosives Fail to Go Off, or a Building Falls in an Unexpected Way

PHILADELPHIA, PA / ACCESSWIRE / March 30, 2018 / Building demolitions usually attract a great deal of attention. There is something spectacular and even awe-inspiring about seeing a large building brought down in a precise, controlled manner. Demolition companies use incredible amounts of explosives to demolish a building in a safe way that doesn't imperil surrounding structures or anyone on the ground.

However, building demolitions don't always go according to plan. In some cases, explosives fail to go off, or a building falls in an unexpected way. These demolition failures demonstrate why any kind of building demolition is a potentially life-threatening event.

The Pontiac Silverdome

Opened in 1975, the Pontiac Silverdome was an engineering marvel when it was first built. By the 1990s, however, the aging structure had become a symbol of the Detroit area's economic decline. Initially closed in 2006, it was later reopened, only to close again in 2013. A planned demolition in 2017 failed when only 10 percent of the explosives inside the building detonated. Demolition experts explained that faulty wiring was responsible for the failed demolition.

Scotland Red Roads High Rises

When Scottish demolition crews attempted to demolish six high rises simultaneously, just four of the buildings imploded. Two high rises collapsed about halfway, and then remained standing upright. Months of investigation revealed that the two buildings left standing had been built with a stronger steel frame than the other buildings - a problem that went undiscovered for five decades due to inconsistencies in the construction records. A report states, "Because of the discovery of discrepancies, the agency that completed the report also explained that the company could have done more to err on the side of caution, especially with regards to pre-weakening the structures."

Demolition Failure in Liuzhou China

In 2009, a failed demolition of a residential tower in Liuzhou, China split the building in two and left one-half tilting precariously to the side. Instead of crumbling to the ground as intended, the other half of the building fell sideways and smacked into the ground on its side. Construction workers were forced to take apart the remaining half of the building with a crane. The Liuzhou building demolition accident is just one in a series of major building demolition failures that have occurred in China in recent years.
