Working on infrastructure projects can sometimes lead to unexpected historical discoveries, as happened during the construction of Line 6's metro project. Our team encountered an ancient tomb belonging to a Qing Dynasty landlord while operating the tunnel boring machine, which halted progress and called for immediate archaeological consideration. In such cases, collaboration between engineers and archaeologists is essential to preserve cultural heritage while continuing construction work. The decision to re-bury the tomb respectfully demonstrates the balance between modernization and respect for history. From personal experience, unexpected finds during construction add a unique dimension to project management. They often require quick adjustments in planning and close communication with cultural heritage experts. Moreover, these discoveries can increase public interest and awareness of local history, fostering a deeper connection between a community and its past. This encounter serves as a reminder that beneath the surface of modern cities lie stories from centuries ago, waiting to be uncovered, respected, and preserved.
