Which construction technique is preferable for the Bluiding Frame construction, RCC or PEB? is among the most frequently asked questions. However, what is a PEB precisely, and how does it differ from conventional building techniques? We’ll review the advantages and disadvantages of pre-engineered buildings in your upcoming project.
What is a Pre-Engineered Building?
A prefabricated element entirely made of steel, ideally galvanized, is called a PEB. After being manufactured at the factory, the parts are sent to the location and assembled using bolts. To satisfy criteria for space, energy, insulation, and other factors, pre-engineered building producers precisely measure and fabricate the wall panels, roofing systems, and structure. PEBs have become increasingly common over the past few decades because of their superior speed, precision, and reusability. Because of its benefits and versatility, pre-engineered steel buildings are now the go-to option for major sectors worldwide.
PEB projects have advantages over traditional concrete and steel constructions, so they are becoming increasingly popular. While steel constructions impart more ductility and deflections to the structure, which is advantageous in resisting seismic forces, concrete buildings are bulky and impart more earthquake weight and less deflection. Pre-engineered building construction gives lower costs, quicker construction, greater quality control, sustainability, and other benefits by combining the best qualities of concrete and steel.
What is Reinforced Cement Concrete (RCC)?
RCC is a composite material used in building. It is composed of steel reinforcement and structural concrete. It has been the recommended option for permanent structures for a long time. It can be shaped into various forms because it is initially liquid. Sand, gravel, cement, and water combine to form concrete, which dries into a sturdy mass. Concrete has a low tensile strength and is only partially strong. Bending it causes it to break. This issue is resolved when steel reinforcement is used. Steel has a high tensile strength, which allows it to turn. Therefore, the steel takes on most of the burden when a bending force is applied to an RCC structure.
A Comparison Between PEB and RCC
RCCs and PEBs are different. One very noteworthy feature appears from the very beginning. A PEB construction manufacturer handles the whole manufacturing process in the factory, whereas RCCs are made wholly on-site. This suggests that only one activity related to pre-engineered steel buildings occurring on-site is erecting steel structures. Below is a comparative analysis:
|Pre-Engineered Steel Buildings (PEB)
|Reinforced Cement Concrete Buildings (RCC)
|Done in shop-controlled conditions.
|Mostly at site in variable conditions.
|Mostly made in Factories hence onsite labor is incredibly low.
|Highly labor intensive. Many number of people on site for many months.
|Precise and fixed, carefully and accurately controlled under supervision in the production facility.
|Variable, non-homogeneous. The properties of concrete vary widely due to variations in its proportioning and mixing.
|Precise and accurate measurements carried out by automated machines. No lapses in materials.
|Potential for significant errors as most of the work is man made on site. Materials can be compromised and it is not easy to identify.
|Steel may carry up to 6 times its own weight.
|The carried load of concrete is almost equal to its weight
|Earthquakes / Wind Resistance
|Highly resistant to earthquakes and wind
|Less resistant to earthquakes and low wind Resistance
|Lighter, simple design and easy to construct.
|Variable and generally require extensive heavy foundations.
|Easy, fast and efficient. Erection costs and time are accurately forecast based on extensive experience with similar buildings.
|Concrete construction takes more time to complete because it must be poured on site and allowed to cure before proceeding.
|Larger, up to 90 meters without interior columns.
|Smaller Spans in general and the larger the span the heavier the structure.
|Higher . For the same cost. pre-engineered steel buildings give you a better height advantage.
|would depend upon foundation , higher you go the foundation has to be stronger.
|Flexible, tailor-made, changes and revisions can be made easily.
Future expansion is simple, easy and cost-effective. And supplier to coordinate changes.
|It is nearly impossible to modify a concrete building to meet changing future needs.
To expand the structure, the contractor must build a new structure with foundations, columns and most likely must break part of the old structure.
|Multiple options available to choose Fire resistant coatings.
|Best suited for Industrial and Commercial.
|Best suited for Offices and Commercial Establishments, Houses, Villas, and Parliaments
|Overall cost is generally slightly more than RCC structures but is justified from a time advantage perspective . Also the costs accurately defined and forecasted.
|Overall cost could be slightly lower than pre-engineered buildings Structures but is difficult to accurately define and forecast the total costs.
As is evident, in most cases, PEBs have come out on top. The increased demand for steel construction producers can be attributed to this. Large organizations typically delegate Plant and office development to reputable PEB structure manufacturers. As with godowns and warehouses, the capacity to take apart, shift, and rent PEB structures has created opportunities for new enterprises. PEBs are becoming increasingly common in most industrial and public building projects, including factories, godowns, metro stations, bus stops, auditoriums, stadiums, etc. Developers are starting to use PEBs even in the residential market. Likely, pre-engineered buildings will eventually replace conventional constructions as costs and technologies advance.
