Structural consultants choose pre-engineered or conventional steel buildings, depending on the project requirements. Both have their advantages and disadvantages. Both buildings have different processes and need design, foundation, framing, and finishes.
The structural consultants have a series of discussions with the client to fine-tune the structure based on the project requirements, timelines, and budget before they freeze the type of building.
How do Pre-engineered steel buildings (PEB) and Conventional steel buildings differ?
- Time: The time for design and building is quicker in PEB. The PEB is tailor-made to suit the project requirements, so the building is manufactured from scratch. Structural software helps optimize the structure. In contrast, conventional buildings are fabricated from components available in the market. The scope for optimization is limited. Hence, the cost is relatively more than PEB.
- Speed of delivery: The PEB delivery timeline can be suited to the project timelines. Targeting the delivery of materials by the time the foundation is ready is relatively easy. However, conventional buildings need more time, and the project timelines proportionately increase.
- Efficient and optimized design: The wastage in PEB is minimal as the structure is custom-made. PEB manufacturers use standard plates, so the material usage is optimal. Conventional structures use ready-made hot rolled beams and columns, increasing the weight, wastage, and thus cost.
- Foundations: PEB needs relatively lighter foundations when compared to conventional buildings.
- Quality control: The quality in PEB is consistent and can be controlled. Whereas in conventional buildings, it is not possible.
Conclusion :
To conclude, the selection of the building depends on the project requirements, project timelines, and material availability. Ultimately, the decision lies with the client, architect, and structural consultants, who decide on the type of building.
