PAST EXPERIENCES

YEAR ORGANIZATION KEY ACCOMPLISHMENTS
2000-2002 PNOC FILOIL DEVELOPMENT & MANAGEMENT CORPORATION Vice President & Chief Operations Officer

Reported to the President and the Board of Directors. Have been seconded from the PNOC Energy Group to turn around the Company.
- Spearheaded the strategic planning to turn around the Company through a short range (1 year), medium range (3 years), and long range (5 years) business plan.
- Reviewed and completed the Master Development Plan of the Business Township concept of development comprising the industrial estate, business/commercial area, institutional, and housing facilities for its 120-hectare property.
- Prepared the Financial Study, the Terms of Reference and the Draft Joint Venture Agreement for the Project.
- Re-engineered the company structure in order to meet its strategic plan.
- Turned around the Company from a non-performing asset to 2nd in term of income within one year.
1996-1988 PNOC PETROCHEMICAL DEVELOPMENT CORPORATION Projects Development Manager

Reported to the President and the Board of Directors. Have been seconded from the PNOC Energy Group to turn around the Company that was handling more than $1 billion petrochemical project.
- Took over the construction management of the Petrochemical Park Project including the loading pier that was already delayed by six months. The schedule was met without effect on the timetable of the Upstream Petrochemical Park Locators.
- Handled the feasibility design of the Naphtha Cracker Plant and the proposed extension of the feedstock pier to accommodate the requirements of the petrochemical complex locators in Bataan.
- Spearheaded the creation of the Safety Committee for the Petrochemical Park operations.
- Prepared the Table of Organization for the Operations Group.
- Handled the coordination and negotiation with the Park Locators and contractors.
1980-2002 PNOC ENERGY DEVELOPMENT CORPORATION - Successfully negotiated in Seoul, Korea the fast tracking of transmission towers fabrication for Leyte A Geothermal Project that was delayed by 3 months.
- Headed the design team to solve the problem of a slope failure due to fault movement threatening the 100Mwe Malitbog Power Plant and a major transmission tower. River was diverted and slope stabilization completed saving the Company approximately $1 million penalty per day of non-operation.
- Solved the problem of plugging the AP-7 geothermal well blowup in Alto Peak, Leyte. Cost was 1/3 that requested by the Consultant of $1.5 million.
- Studied and revised the seismic design parameters for the geothermal projects in the Philippines effecting significant project cost reduction of 15%.
- Spearheaded the study of corrosion effect to concrete due to geothermal environment exposure. This resulted to changing the type of cement specified that reduced the cost of concrete works by 30%.
1977-1980 SAN MIGUEL CORPORATION - Developed a foundation method of avoiding piles for equipment on alluvium soils thus resulting to cost savings and decrease in construction time.
- Made a performance based design that rehabilitated the Ilocos Coca-Cola Plant after it sustained serious damage during the 1980 M=6.8 earthquake.
