Philippine Institute of Volcanology and Seismology (PHIVOLCS) Director Renato Solidum disclosed that the project site of the proposed P736 billion New Manila International Airport in Bulacan showed some indications of flooding and other geohazard concerns.
During the virtual hearing of the Committee on Public Services on the franchise of San Miguel Aerocity Inc., Solidum underscored that “the multi-billion airport project is sitting on soft ground and the location is prone to frequent flooding.”
The PHIVOLCS official added that the area is mainly underlain by sand and the water table is very shallow, requiring special engineering interventions to make buildings and infrastructure resilient to hazards due to earthquake events or weather-related activities like heavy rainfall.
“The area chosen for the project stands on tender ground susceptible to shaking, and liquefaction and the flooding remains a big concern because the project site is a part of Bulacan known to easily submerge in water during heavy rains,” warned Solidum.
He also stressed that the project requires disaster risk reduction and business continuity protocols alongside the construction of a proper drainage system.
In response, San Miguel Holdings Corporation Operations Head Edgar Doña said that the concerns and issues raised by the PHIVOLCS director had been factored into the detailed engineering design which is being finalized by the company’s safety experts.
SMC’s Government Relations Head Melissa Encanto-Tagarda added that the company tapped foreign partners who are experts in airport construction and safety designs.
