5 Worst Building Fails
Tower of Pisa – Pisa
Probably one of the most famous architectural fails in the written history of the world, the Tower of Pisa took 177 years to complete. The tower started to lean 5 years after the initial construction began. The reason? A combination of the thin foundation that supports the tower and the unstable soil upon which it was built. Throughout the 177 years it took to complete the structure, architects and builders tried to compensate the sinking side of the tower by building tilted floors. Before the massive restoration efforts began in the 20th century, the tower stood at a 5.5-degree angle. Today, the tower leans at less than 4 degrees.
Ronan Point Apartment Building – London
In the mid 1900s, the Ronan Point Apartment Building was part of the wave of cheap towers created from pre-fabricated concrete panels. Due to the size of the project, builders and architects skipped some of the quality control tests that should have ensured the building’s safety. As a result, in 1968, the whole building collapsed due to an explosion in an apartment situated on the 18th floor of the total of 22 floors. 4 people were killed and another 17 were injured in the collapse. Later studies showed that the water-damaged bolts and joints had been filled with newspaper instead of concrete.
Hyatt Regency walkway collapse– Kansas City
One of the deadliest structural failures in the history of the world, the two walkways that collapsed in the Hyatt Regency killed 114 people and injured another 216. The numerous setbacks and delays didn’t eventually prevent the hotel from being opened in the early 1980s. One year after its inauguration, during a tea ceremony held in the massive atrium of the hotel, the two suspended walkways collapsed onto the atrium floor. Because the original plans for the walkways weren’t followed, the walkway on the 4th floor was flawed by design. The added weight of the hotel patrons who were gathered to watch the tea ceremony led to the collapse. The upper walkway collapsed onto the lower walkway, both collapsing further onto the atrium floor.
Centre Point – London
Initially one of the tallest office buildings in London, the Centre Point tower is also one of the most notorious structures. Erected in the center of West End, the tower was completely unused for more than a decade after its inauguration. Although initially built for commercial purposes, the owner of the tower refused to rent out single floors for business owners. It was all or nothing. Eventually, over the span of almost half a decade, the building was refurbished on multiple occasions, acting as commercial and office building for most of the time. Professional after builders cleaners were hired before and after each refurbish process. The building is currently being refurbished into luxury flats.
The Lotus Riverside – Shanghai
The Lotus Riverside is a residential apartment complex consisting of 11 symmetrical buildings, each 13-floors high. In 2009, Block 7 of the apartment complex collapsed onto its side, almost completely intact. The culprit was later found the collapse of the riverbanks of the nearby river. During the construction of the underground parking lot of the building, water infiltrated the foundation of the building, eventually leading to its collapse.
