Pre-Engineered Metal Buildings: Design, Components, and Cost- Value Engineering Compared to Traditional Portal Frame Buildings

Pre-engineered metal Buildings (PEMBs) have emerged as a game-changer in the ever-evolving construction industry, offering a highly efficient, economically optimized, and environmentally sustainable solution compared to conventional portal frame buildings. For engineering design consultants like Integra Consulting Services, understanding the intricacies of PEMBs is crucial to delivering innovative and efficient solutions to clients.

This blog delves into the design, components, and cost-value engineering of PEMBs, comparing them to traditional portal frame buildings. We will also explore how PEMBs can benefit your next project and why Integra Consulting Services is your ideal partner for engineering design in the Middle East.

What Are Pre-Engineered Metal Buildings (PEMBs)?

Pre-Engineered Metal Buildings are factory-built structures designed and fabricated off-site using standardized components. These structures are subsequently transported to the construction site for systematic assembly and installation. PEMBs are widely used for industrial, commercial, and institutional projects due to their versatility, durability, and cost efficiency.

Key Components of PEMBs

PEMBs consist of several key components, each playing a vital role in the structure’s performance and functionality:

Primary Framing

Rigid Frames: The main structural elements, consisting of columns and rafters, are designed to withstand vertical and lateral loads.
Endwall Frames: Provide support at the building’s ends and accommodate openings for doors and windows.

Secondary Framing

Purlins and Girts: Horizontal members that support the roof and wall panels, respectively.
Eave Struts: Connect the roof and wall systems at the eave level.

Roof and Wall Systems

Roof Panels: Made of metal sheets designed to provide weatherproofing and insulation.
Wall Panels: Offer aesthetic appeal and protection against environmental factors.

Bracing Systems

Rod Bracing: These diagonal members provide stability against wind and seismic loads.
Flange Bracing: Ensures the structural integrity of the primary frames.

Accessories

Doors and Windows: Customizable to meet project requirements.
Insulation: Enhances energy efficiency and thermal performance.
Ventilation Systems: Ensure proper airflow and temperature control.

Design Considerations for PEMBs

Designing a PEMB requires a thorough understanding of project requirements, environmental conditions, and regulatory standards.

Key considerations include:

Load Calculations

Dead Loads: The self weight of the structural components.
Live Loads: Temporary loads such as snow, wind, and occupancy.
Seismic Loads: These are earthquake-induced forces, particularly relevant in the Middle East.

Material Selection

High-Strength Steel: Offers durability and reduces material usage.
Galvanized Steel: Provides corrosion resistance, essential for harsh climates.

Customization

Architectural Flexibility: PEMBs can be tailored to meet aesthetic and functional requirements.
Expandability: The PEMB structure is designed to accommodate future expansions.

Compliance with Standards

International Building Codes (IBC): Ensure safety and performance.
Eurocodes: Widely used in the Middle East for structural design.

Cost-Value Engineering: PEMBs vs. Traditional Portal Frame Buildings

Cost-value engineering is a critical aspect of any construction project. Let’s compare PEMBs and traditional portal frame buildings across key parameters:

Construction Time

PEMBs: Factory fabrication and modular assembly significantly reduce construction time.
Traditional Portal Frames: On-site fabrication and assembly lead to longer project durations.

Material Efficiency

PEMBs: Optimized use of high-strength steel reduces material waste.
Traditional Portal Frames: These pose Higher material consumption due to less efficient designs.

Labor Costs

PEMBs: These involve reduced on-site labour due to pre-fabrication.
Traditional Portal Frames involve higher labour costs due to extensive on-site work.

Maintenance and Durability

PEMBs: Galvanized steel and advanced coatings ensure long-term durability and low maintenance.
Traditional Portal Frames: Require regular maintenance and are more susceptible to corrosion.

Sustainability

PEMBs: Recyclable materials and energy-efficient designs contribute to sustainability.
Traditional Portal Frames Involve a higher carbon footprint due to material waste and longer construction times.

Advantages of PEMBs

Speed of Construction: Faster project completion reduces overall costs.
Cost Efficiency: Lower material and labour costs.
Design Flexibility: Customizable to meet specific project needs.
Durability: Resistant to harsh environmental conditions.
Sustainability: These are designs based on eco-friendly materials and are energy-efficient.
