QUEZON CITY, Jan. 17 (PIA) – A ranking public works official on Wednesday said their agency will fortify this year several bridges and elevated highways in the National Capital Region in preparation for destructive earthquakes.

Speaking from the sidelines of the Philippine Earthquake Model Atlas launch held at the Philippine Institute of Volcanology and Seismology (PhiVolcs) in U.P. Diliman, Department of Public Works and Highways (DPWH) Undersecretary for Planning and PPP Maria Catalina Cabral said at least 25 bridges and three major overpasses are due for repairs in 2018 to ensure structural integrity in case a 7.2-magnitude quake devastates the capital. 

"Under our 2018 budget, we are funding and we are going to retrofit and strengthen 25 bridges and three flyovers in Metro Manila that will cost us one billion pesos… These are already funded," Cabral said. 

The official said among these bridges and passageways, top priority would fall on the 114-linear meter Guadalupe Bridge on EDSA and 98-linear meter Lambingan Bridge in Sta. Ana, Manila.

"Under Metro Manila Priority Bridge Seismic Improvement Project we are going to rehabilitate the outermost part of the Guadalupe Bridge first and whether we encounter traffic we have to do that because that bridge is over 50 years old," she emphasized.

She said the DPWH has been assessing public infrastructures with a goal to make these structures more resilient and durable against strong seismic movements in the future. 

"We've done vulnerability risk assessment of public buildings. We've finished inspecting some 4,900 plus structures, of which, majority of that are school buildings and hospitals," she said. 

"It is important to safeguard the safety of all buildings as well as important lifeline infrastructures such as bridges that make both economic and social life of the people," she added. 

Cabral joined Department of Science and Technology Secretary Fortunato de la Peña and DOST-PhiVolcs OIC and Undersecretary for Disaster Risk Reduction and Climate Change Dr. Renato Solidum Jr. in launching the Philippine Earthquake Model Atlas, which aims to help engineers in designing earthquake resilient buildings. 

The atlas is a handbook of probabilistic seismic hazard maps that will aid engineers in designing earthquake resilient buildings and structures. It can also be used as a tool for land use, urban planning, and disaster risk management plans of local government units, government agencies, and other stakeholders. 

"We will also make the Philippine Earthquake Model Atlas available today in the agency website (phivolcs.dost.gov.ph) for public reference," Solidum said. 

These maps were generated through the collaborative expertise of seismologists, geologists, engineers, and researchers from DOST-Phivolcs, in consultation with various concerned agencies, such as the Metropolitan Manila Development Authority, the Office of Civil Defense, Metro Manila LGUs, and the DPWH, among others.
