Why and here is how some get provide lower quote for tensile membrane structures:

• Lower Grade Fabric: This can have significant drawbacks:
  • Reduced Strength: The fabric might not be able to withstand the intended loads, leading to potential collapse.
  • Fire Resistance: Lower fire resistance ratings pose a safety hazard in case of fire.
  • UV Resistance: Degradation under UV exposure can shorten the lifespan of the structure and compromise its appearance.
• Thinner Cables and Steel Structure: This can compromise the structural integrity of the entire system:
  • Deflection: The structure might sag excessively under its own weight or external loads.
  • Collapse: In extreme cases, thinner elements can lead to catastrophic failure under heavy wind or snow loads.
• Reduced Wind Speed in Design: This is a major safety concern, as it underestimates the actual wind forces the structure might experience. It could lead to:
  • Structural Damage: The structure might not be strong enough to handle actual wind loads, potentially leading to damage or collapse.
  • Safety Risk: A structure designed for lower wind speeds and lower safety factor could pose a danger to occupants and surrounding areas during strong winds.

• Simplifying Design with no creativity: While some simplification is possible for optimization, excessive simplification can lead to:
  • Inefficiency: The structure might use more material than necessary, increasing costs in the long run.
  • Structural Issues: An overly simplified design might lack the necessary strength or stability for the intended purpose.
• Junior Engineer Running FEA Software: Finite Element Analysis (FEA) is a complex tool. Inexperienced engineers might:
  • Miss Crucial Factors: Omit important details from the analysis, leading to an inaccurate prediction of the structure’s behavior.
  • Misinterpret Results: Misinterpret the FEA results, potentially leading to design flaws and safety hazards.
• Nesting Pattern in All Directions: While efficient fabric use is important, nesting in all directions can lead to uneven stress distribution.
• Manual Plotting and Cutting Fabric: While manual methods can be used, they have limitations:
  • Increased Risk of Errors: Manual plotting and cutting are more prone to human error compared to computer-controlled cutting systems.
  • Inaccuracy: Manual methods might not achieve the same level of precision as computer-controlled cutting, potentially compromising the final form of the structure.
