Construction activities worldwide are increasing at a tremendous rate and the costs are also increasing in a day-by-day manner. Pre engineered buildings put forwards an excellent solution to all the complicated problems associated with the conventional steel and other type of buildings. At present in a global manner, pre-engineered building or PEB system is becoming an eminent segment in the construction industry. Pre engineered building is less expensive than conventional construction and can be designed according to the specific requirements. The design and construction of pre engineered building is cost effective and less time consuming. The pre engineered buildings can be disassembled and transported to another location for re-erection if necessitates. The maintenance costs of pre engineered building are low compared to the usual method of construction. These buildings have long life expectancies and the impact of steel on environment is far less than using a non-renewable resource and they keep the impact to the environment minimal. As most of the materials used in the construction of pre engineered buildings are recyclable; it conserves the energy and has minimum impact on ecology and environment. So pre engineered building is the only remedy to the construction industry in the creation of an industrial, commercial, recreational or other type of building units within the stipulated time frame with limited usage of material, energy, manpower and without making much harm to the ecology and environment. Thus pre engineered buildings are the prime contributors for the sustainable development of the nation.
