At PT. Rayasurverindo Tirtasarana, I supported civil works quality supervision for the Patimban Port Development Project (II), Package 8. I monitored site works and materials testing against project specifications, regulations, and SNI, JIS, and ASTM standards.
I supervised reclamation works, including Cement Deep Mixing (CDM) and dredging. I also supervised berth structure work, from precast concrete installation and pile driving to slab anchorage and apron installation.
At PT. Masterpancang Pondasi, I prepared heavy-equipment mobilization plans and monitored work against agreed schedules. I also prepared progress reports, billing documentation, cost estimates, and budget plans.
Earlier, as Field Supervisor at CV. Graha Plasterindo, I coordinated two housing construction and renovation projects and helped shorten project duration by increasing daily work-target achievement. At PT. Linde Indonesia, I maintained company gas-cylinder asset records and coordinated asset movement information.
