Today marks the first anniversary of the privilege speech we delivered before the House of Representatives on 07 October 2025, entitled "Beyond the Bottleneck: Rebuilding Trust in Our Nation's Infrastructure – The Plight of the Mabuhay Underpass." In that speech, we placed on record the concerns surrounding the delayed project and called for accountability, transparency, and concrete technical solutions.
But the work neither began nor ended with that speech.
Even before we formally returned to the House, we had already moved to address the concerns surrounding the project, writing to the Commission on Audit on 02 June 2025 and holding a coordination meeting with DPWH personnel on 28 June 2025.
We also pursued legislative oversight and sustained technical engagement to determine what went wrong and what needed to be done to move the project forward. Our office organized a Project Inspectorate Team, conducted multiple ocular inspections, and consulted engineers, technical experts, and other stakeholders.
We likewise initiated and took part in a series of coordination meetings and dialogues with DPWH officials, the contractor, consultants, SOCOTECO II, and other concerned parties, bringing the issues on the ground to the proper agencies and technical authorities.
These engagements examined the critical challenges encountered during implementation, particularly groundwater seepage, the adequacy of geotechnical investigations, drainage and catchment capacity, design revisions, variation orders, and the resulting delays and additional costs. Among the key technical concerns we raised was the need for a more extensive geotechnical investigation and Electrical Resistivity Tomography (ERT) to better determine subsurface conditions and guide appropriate engineering interventions.
The Mabuhay Underpass was conceived to address one of General Santos City's longstanding traffic bottlenecks, but its implementation ran into significant technical and project-management problems. For us, the issue was never simply about assigning blame. It was about establishing the facts, protecting public funds, demanding accountability, and working toward a solution that would ultimately serve the people of General Santos.
Today, we look back on that journey with gratitude. On 29 July 2026, the Mabuhay Underpass finally opened to traffic, and it now serves motorists, commuters, businesses, and communities across General Santos City.
Its completion underscores an important lesson: proper planning, rigorous technical studies, transparent implementation, and sustained public oversight matter. When government institutions work together, heed technical expertise, confront problems honestly, and stay focused on the public interest, even the most difficult infrastructure projects can be seen through.
From the floor of Congress to the project site, our commitment remains clear: Hindi tayo titigil hangga't hindi natatapos nang maayos ang bawat proyektong para sa GenSan.
