The 70’s – 80’s: Our Inception Era
Originally established in 1975, C. S. Santiago Construction Co. Inc. (CSSCCI) started as a single proprietorship firm with a Small B category from PCAB engaged in the construction of houses, buildings, roads, canals, drainage systems and bridges.

It was organized as a duly registered corporation in 1985 and through the years, the company expanded from purely land based projects to marine construction.
