The Premise
The limiting factor for Gulf Giga-Projects (NEOM, Red Sea Global) is not capital; it is Thermodynamics. The human body cannot cool itself via sweating once the "Wet Bulb Globe Temperature" (WBGT) exceeds 31°C. We are approaching a physical ceiling on outdoor labour productivity.
Intelligence Update: The Labour Cliff
The Metric: At WBGT 32°C, safe work/rest ratios mandate 45 minutes of rest for every 15 minutes of work. Productivity effectively hits zero.
The Data: The Gulf region is seeing a 200% increase in "Red Flag" days over the last decade.
The Impact: Construction schedules drafted in London boardrooms (assuming 8-hour shifts) are physically impossible to execute on site.
Field Evidence: The Physiological Limit
Qatar realised early that summer play was impossible. They invented "Dr. Cool" air conditioning technology for open stadiums and shifted the entire tournament to Winter.
The Lesson: You cannot fight physics. You must engineer around it or reschedule it.
Temperatures in Delhi hit 49°C. Outdoor construction and logistics ground to a halt not by law, but by physical collapse.
The Lesson: For projects like The Line (NEOM), reliance on manual labour is a single point of failure.
The Verdict
"Climate Resilience" is usually discussed as flood defence. In the Gulf, it is Automation. The only way to build Giga-Projects on schedule in 2030 is to remove the human from the outdoor loop. Investing in Construction Robotics is not an efficiency play; it is a continuity play.
