More than 25 years assembling, running and repairing tunnel boring machines across Singapore, Malaysia and Dubai.
Jasim Uddin has spent over 25 years keeping tunnel boring machines alive — assembling them in launch shafts, running them at the face, and fixing them when the ground fights back. He began as a mechanic and welder on Samsung, Taisei and Sembawang tunnel contracts, mastering TBM assembly, dismantling and troubleshooting from the workshop floor up.
As mechanical superintendent, he supervises the mechanics and welders who maintain, repair and assemble TBMs; distributes and evaluates work assignments; plans machine and operator schedules for entire tunnel teams; and drills crews on safety procedures and the proper handling of tools and equipment.
His superintendent career runs through the industry's most respected names — Obayashi, MMC-Gamuda's Klang Valley MRT (where he helped commission the world's first variable-density TBM fleet), Penta-Ocean, and Yu Sin Engineering, where he continues to lead TBM operations on Singapore's newest lines.
35 tunnel boring machines across 13 contracts in 4 countries.
