This study evaluates rock-socketed pile behavior in weak rock using two bi-directional static load tests in Dubai. Results show that conventional UCS–skin friction correlations can overestimate capacity, while test-based value engineering reduced pile lengths by over 22%. This optimization significantly improves cost, time, and overall foundation performance.
