  • Structural Engineer
  • “When I was young, I had the opportunity to witness the construction of a 61-story concrete skyscraper near my house in Bangkok. I was impressed with the slenderness of the building and the efficiency of the construction using slip-formed concrete techniques. I knew then that I had to become a structural engineer.”
