The global construction industry is projected to reach $17.5 trillion by 2030 (14.7% of global GDP), yet design errors remain a major challenge, costing $85 billion annually. These design mistakes account for 40% of construction issues, with total direct and indirect costs reaching $865 billion worldwide.

Causes and Impacts of Typical Errors
Typical errors include inaccurate site assumptions, incorrect material choices, and oversight in foundations, structural redundancy, and construction sequencing. Common causes are tight schedules, limited budgets, poor communication, last-minute changes, and insufficient technical expertise.

Cost Implications of Design Mistakes
Late detection increases expenses through redesigns, rework, or demolition. Additional costs include:
• Correction Costs: Redesign or repair
• Construction Delays: Extra labor and equipment
• Safety Risk Costs: Redesign and safety measures
• Quality Control Costs: Inspections and adjustments
• Project Reassessment Costs
• Operational & Maintenance Costs
• Legal & Contractual Costs

Early planning and review prevent typical errors, saving time, money, and resources.
