Pre-Engineered Building concept involves the steel building systems which are predesigned and prefabricated. As the name indicates, this concept involves pre-engineering of structural elements using a predetermined registry of building materials and manufacturing techniques that can be proficiently complied with a wide range of structural and aesthetic design requirements.
The basis of the pre-engineered buildings concept lies in providing the section at a location only according to the requirement at that spot. The sections can be varying throughout the length according to the bending moment For today and in future, Steel has become the material of choice in building Construction compared to concrete and timber. Thus steel building designs have become more flexible, durable and adaptable. Thus, Pre-engineered Buildings are ideal for use in Non- residential wide span, Low rise Buildings. Among the advantages of pre-engineered buildings is Low cost, Consistent quality control and fast delivery. Pre-engineered buildings are used for diverse applications such as factories, Warehouses, Offices, Shopping malls, Schools, Hospitals, Community Buildings and Several more.

ADVANTAGES OF PRE-ENGINEERED BUILDINGS

Following are some of the advantages Pre-Engineered Building Structures:

• Buildings are generally constructed in just 4 to 8 weeks after approval of drawings.
• Pre-engineered buildings will thus reduce total construction time of the project by at least 30%. This allows faster occupancy and earlier realization of revenue.
• Because of computer systems approach, considerable saving is achieved in design, manufacturing and erection cost.
• These can be easily expanded in length by adding additional bays. Also expansion in width and height is possible by pre designing for future expansion.
• Buildings can be supplied to around 90m clear spans. This is one of the most important advantages of pre-engineered buildings giving column free space.
• Buildings are manufactured completely in the factory under controlled conditions, and hence the quality can be assured.
• Pre-engineered Buildings have high quality paint systems for cladding and steel to suit ambient conditions at the site, which in turn gives long durability and low maintenance cost.
• Steel members are brought to site in CKD conditions, thereby avoiding cutting and welding at site. As pre- engineered buildings sections are lighter in weight, the small members can be very easily assembled, bolted and raised with the help of cranes. This allows very fast construction and reduces wastage and labour requirements.
