Pre-engineered buildings
Pre-engineered building systems offer real value to their customers without compromising on the durability, seismic and wind resistance, or aesthetic appearance. Cost savings start right at the drawing preparation stage. Systems engineering and fabrication methods help lessen interim financing costs through quicker construction and minimal expense for field erection. Additional benefit on this is earlier occupancy of the facility and a head start on day to day operations by the client. Besides the costs, there is a guarantee of factory built quality and uniformity in design as well as fabrication. These systems are energy efficient as well, include watertight roofing systems, let easy disassembly or future expansion and have the lowest life cycle maintenance costs.
Benefits of Pre-engineered Buildings: ∑ Enhanced speed of construction and fast return on investment ∑ Increased durability and seismic dependability ∑ Simple construction, maintenance and refurbishing ∑ Environment friendly structures ∑ Increased quality of material, design and construction ∑ Great value for money ∑ Quicker delivery and erection saving around 30 to 40% of project time ∑ Sustainability in construction through reuse of most materials ∑ Optimized design of steel lessening weight ∑ Insulated from heat and sound, as per the requirement ∑ Better rainwater harvesting through gutters and down take arrangements
A Commending Future for Pre-Engineered Building Systems ‘Pre-engineered or Pre-fabricated steel building’ is any part of a structure that’s manufactured before it comes on the building site. The concept of the preengineered building (PEB) is one where the fabrication is completed in a controlled environment with the help of latest technology and then subsequent erection is executed. Though, earlier only off the shelf products were available in these configurations helped by the technological development, tailor made solutions are also made using this technology in very short durations.

Currently the total production of steel in the country is about 45 Mn ton against 1280 Mn of world. Per capita steel consumption in India is 42kg while it’s 270kg in China. In the next 5 years, the production of prefabricated steel structure will be doubled and with efforts of some organisations, steel intensive construction might rise up to 22Mn ton. Due to the benefits of PEB.
Advantages of Pre-Engineered Building Systems in detail : Reduction in Construction Time: As a result of the systems approach, the use of high strength steel, use of tapered built up sections which are optimized by the computerized design program and the use of continuous light gage secondary steel section, there’s an overall reduction in steel weight, cost and time relative to conventional steel construction. Pre-engineered buildings are a predetermined inventory of raw materials that over the time has proven to satisfy a wide range of structural and aesthetic requirements. The components are engineered in advance and standardized. Use of these standard components lessens the engineering, production and erection time. Use of customized software for design and drafting enhances the speed of the project.
The production line is highly sophisticated; having multi cutting torches, auto welders’ shear cutting machines, etc., which greatly lessen the time of fabrication of built up components. Roll forming machines for producing Z&C members and sheeting, having standard dimension, enhances the production capacity of secondary members. Using standard accessories highly enhances the speed of production and erection. Typically, buildings are delivered in just a few weeks after the drawings are approved. Anchor bolts and foundation are cast in parallel with manufacture of the building.
Design: Pre-engineered metal and steel buildings are primarily formed of standard sections and connections, the design time is lessened to a great extent. Specialized computer evaluation and design programs optimize material require. Drafting is also computerized using standard details that lessen project custom details. The low weight flexible frames provide higher resistance to seismic forces.
Foundations: Pre-engineered buildings are about 30% lighter than the traditional steel structures. Hence, the foundations are of simple design, simple to construct and lighter weights.
Savings in Cost: As a result of the systems approach, there is an exceptional saving in design, manufacturing as well as the cost of site erection. The structural elements are shaped to follow the stress diagram of the member, thus lessening weight, cost and load to foundations. The secondary members and cladding nest together thus lessening transportation cost. The overall price per square meter might be lessened as much as 30% lower than traditional steel.
Flexibility of Expansion: By adding additional bays, buildings can be easily expanded in length. Also, expansion in width and height is possible by pre-designing for future expansion.
Low Maintenance: Buildings are supplied with high quality paint systems for cladding and steel to suit ambient conditions at site, which results in long durability and low maintenance costs.
Phenomenal Growth Rate for Pre-engineered Steel & Metal Buildings in Future ∑
The increasing popularity of PEB systems in the industrial sector and the development of infrastructure have propelled the Indian pre-engineered steel buildings market to experience robust growth.
∑
Sectors including power, logistics, automotive, pharma, FMCG and capital goods offer huge growth opportunity for PEB in India.
∑
In 2011, the structural steel buildings market in India was around 5 to 5.5 million, of which around 9.5 to 10% accounted for the PEB market in India. It’s expected that the market in terms of volumes will reach 9,00,000 MT by 2016, at CAGR of 11.2%.
∑
By 2030, the commercial building sector in India is estimated to reach a target of 20.44 billion square feet from the current 10 billion square feet. It’s expected that nearly 36% of the 2030 target had already been constructed and about 66% of the building stock is yet to be constructed
∑
In the next 10 years the scope for pre-engineered metal & steel buildings is immense, with the beginning and speedy progress of the Metro rail system.
How PEB Systems are superior over Conventional Construction?
PEB systems are extremely advantageous over the conventional buildings and are really useful in case of the low rise buildings. Pre-engineered buildings are usually low rise buildings; however, the maximum eave heights can go up to 25 to 30 meters. Such buildings are perfect for offices, houses, showrooms, shop fronts etc.

Furthermore, use of pre-engineered metal buildings leads to absolutely no mess of sand and cement, walkable ceilings, power savings, progressive and nonprogressive panel systems for walls. With the help of such structures, one can provide a common man with a house created under strict quality control with a longer life span and with highest level of safety against natural disasters such as cyclones and earthquakes.
