The company made its presence further known within the Western and Central Mindanao region in the field of subsurface soil investigation when in September 1999, the company was commissioned to conduct subsurface soil investigation on the President's SALAM Bridge Project for the Autonomous Region for Muslim Mindanao (ARMM).
The bridge sites covered the provinces of Tawi-tawi, Maguindanao, Lanao, Cotabato, and Sultan Kudarat. Consequently, the Department of Local Government (DILG) engaged the company's services for the various local government bridge projects located from as far as La Union Province in Northern Luzon to Panay Province in the West, to the Bicol Region in the East, and back to mainland Mindanao.
