30 Oct The Resurgence of Prefabricated Buildings
The future of construction may have its roots in the past. Once an emergency measure, prefabricated buildings may be our best hope for a sustainable industry. The concept of assembling a building from pre-made parts is far from new. Over 4 000 years ago, the builders of Mesopotamia saw this as a valuable time-saving option. Later, the Romans adopted the same technique to construct their forts, and some are still standing and remain functional. Among the more recent examples of prefabricated constructions were the wooden sheds built in England and shipped to California to house prospectors and miners during the gold rush in the 1840s. In 1851, the iconic Crystal Palace was built for Britain’s Great Exhibition and later dismantled and relocated. Thirty-six years later, the Eiffel Tower was erected using accurately precast metal beams. However, perhaps the first large-scale construction of prefabricated buildings or prefabs, as they became known, was to provide temporary accommodation for Britains left homeless following World War II. In practice, many are still occupied today, indicating a future for prefabrication in the construction industry. Prefabricated Buildings Reduce Dependence on Concrete Today, the construction industry’s biggest problem is its widespread reliance on concrete and its contribution to the...
