|Feature||Pre-Engineered Steel Buildings (PEB)||Concrete Buildings (RCC)|
|Fabrication||Done in shop-controlled conditions.||Mostly at site in variable conditions.|
|Material Specifications||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.|
|Dimensions||Precise and accurate measurements carried out by automated machines.||Potential for significant errors as most of the work is man made on site.|
|Capacity||Steel may carry up to 6 times its own weight.||The carried load of concrete is almost equal to its weight|
|Material Foundations||Lighter, simple design and easy to construct.||Variable and generally require extensive heavy foundations.|
|Erection||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.|
|Clear Spans||Larger, up to 90 meters without interior columns.||Smaller and the larger the span the heavier the structure.|
|Changes||Flexible, tailor-made, changes and revisions can be made easily.|
Future expansion is simple, easy and cost-effective. One 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.
|Fire Resistance||Needs more protection (multiple options available).||Good Resistance|
Industrial and Commercial.
|Houses, Villas, and Parliaments|
|Cost||Overall cost is generally less and accurately defined and forecast.||Overall cost could be higher and is difficult to accurately define and forecast.|
