Founded by Engr. Rynor G. Jamandre, a topnotcher in the Civil Engineering board exam and one of the few Filipinos certified by the London-based Royal Institution of Chartered Surveyors (RICS), and Engr. Timothy E. Cleveland, a US Military Engineer based in Washington, QSI was established to serve both local and international projects. Our forward-thinking approach, which includes anticipating future needs and understanding project costs and profitability before they commence, has been a key advantage that has propelled QSI to its current position in the market.
