  • History Lessons
    Historians contend their subject matter’s utility helps us understand ourselves and the societies in which we live. To borrow an idea from civil engineering—we must understand the foundation before we build upon it. Looking beyond the literal interpretations, in the tunnelling industry without history one cannot appreciate the (comparative) ease, comfort and safety of today’s work environment and modern equipment.
