Welcome to the Philippines' foremost infrastructure engineering company. As designers and construction managers, Design Science, Incorporated (DSI) has rendered notable engineering projects of various magnitudes for government and private institutions. Founded in 1981, DSI provides professional technical services in planning, special studies, civil engineering, architecture, surveying, energy management, power audit and project management.

We support our public and private sector clients at every stage, from initial concept, financial feasibility, engineering to project completion and beyond. In simple terms, the world of DSI is the water we drink, the roadways we travel, the buildings we visit, the industries in which we work, and the neighborhoods we call home.

We hope to make a name, too, in renewable energy and energy efficiency systems.
