Builders are responsible for physically constructing the building. They often manage the entire construction process from excavation to completion. This includes ordering materials and liaising with other contractors such as plumbers, electricians and bricklayers to do specialist work at appropriate times.
During the design process, builders can advise on the most suitable construction techniques and warn clients about potential difficulties. During construction, builders ensure that materials and methods used are according to the approved plans and meet the standards required by the building surveyor.
