What is the Difference Between PEB and RCC construction?

Pre-Engineered Buildings (PEB), Reinforced Cement Concrete (RCC) buildings, and Concrete Shell structures are three prominent construction approaches widely utilized in the industry for erecting distinct structures. The choice between these methods depends on various factors, including regional climate conditions and the project's specific requirements.

Pre-engineered building construction is often favored in cold regions due to its superior tensile strength compared to RCC. Conversely, RCC construction is better suited for hot regions. The following article will delve into a comprehensive analysis of these PEB and RCC construction methods.

Difference Between Pre-Engineered Buildings (PEB) and Reinforced Cement Concrete (RCC) Constructions

Explore the top difference between pre-engineered buildings and reinforced cement concrete constructions right in the below table. 

Feature	PEB (Pre-engineered Building)	RCC (Reinforced Cement Concrete)
Components	Pre-engineered building structures consist of primary & secondary frames, roof & wall panels, sandwich panels as well as other accessories.	RCC structures consist of beams, staircases, columns, slabs, and foundations.
Dimensions	Accurate measurements are made by using automated machinery.	Potential for significant errors since the construction involves man-made work and labor.
Fabrication	It is done under controlled conditions at production facilities.	It is done on-site under the influence of variables that affect the construction quality.
Casting	Quite costly as Steel needs to be cast in commercial size and needs to be imported.	The fluid nature of concrete makes it easier for it to be cast into any shape and size.
Capacity	Steel has six times more capacity, which makes it an ideal choice to use for PEB structure.	Concrete supports load equal to its own weight.
Strength	Steel works well and behaves in a linear pattern with tension.	Concrete has good compressive properties, but it's weak in terms of tension and breaks easily.
Changes	Pre-engineered building construction is flexible, amendments can be made easily.	Once constructed it's difficult to change to an RCC structure.
Specifications	Material specifications are precise, fixed, and can be controlled under supervision.	Specifications are non-homogeneous and variable; the primary reason for this is the flexible property of concrete to change its properties with the change in the proportion of other materials used for manufacturing.
Availability	Steel isn't available for use and needs to be imported.	Materials required for shell construction are locally and easily available.
Height	Extremely high buildings can be constructed using Pre-engineered buildings construction as steel is lighter material.	Concrete's shorter comparatively, considering the increased value of dead loads with the growth in building height.
Span	The clear span is larger.	The clear span is relatively quite small.

 

Ending Note

When it comes to constructing discrete structures, different methods, such as Pre-Engineered Buildings (PEB) and Reinforced Cement Concrete (RCC) constructions, are available to meet diverse project requirements. While each approach has unique advantages and applications, PEB construction stands out in several ways.

Pre-engineered building construction offers many benefits, including time & cost efficiency, design flexibility, and ease of expansion. With off-site fabrication, Pre-engineered buildings can be assembled on-site, saving valuable construction time and reducing labor and equipment costs. The modular design of PEBs allows for seamless additions or modifications, accommodating future growth or changing needs with minimal disruption.
