In this report, an attempt is made to take a look at the use of cast iron, wrought iron and steel in the construction of buildings and civil engineering structures. These materials have been extensively used in construction for a fairly long time and many outstanding and historical buildings have been built with the use of iron and steel. Iron and steel are mostly used as the dominant structural material to provide shape and strength to the frame of the construction. The report takes a look at the Millennium Dome in the United Kingdom and provides its readers with an extensive bibliography for their use.
