Who is Mark Allan Arevalo?
Mark Allan Arevalo emerged publicly as Wawao Builders’ top executive after the company’s rise in government flood-control contracts. According to press reporting presented at the Senate inquiry, Wawao Builders expanded aggressively between 2019 and 2025, taking on dozens of contracts—many of them linked to flood control work in Bulacan and nearby provinces. The firm has become a focus of scrutiny amid broader investigations into anomalous projects and potential irregularities within DPWH flood-control procurements.
Company background: Wawao Builders in brief
Wawao Builders reportedly began as a small entity that later secured multiple DPWH contracts. Media summaries and committee briefings say the firm handled dozens of flood-control assignments—numbers reported in different outlets range from dozens of completed projects to scores of contracts in Bulacan alone. This contracting activity became a red flag when public audits and citizen complaints suggested that some projects were “ghosts” — recorded and paid for on paper but not actually constructed or not meeting specifications. Officials have flagged this pattern for further investigation.
The Senate hearing — what happened
During the Senate Blue Ribbon Committee session convened to investigate irregularities in flood-control spending, senators asked Arevalo directly whether Wawao Builders had been involved in any “ghost” projects in Bulacan. Rather than answering those questions, Arevalo invoked his constitutional right against self-incrimination and said his lawyers advised him not to speak because the Senate report might recommend filing charges. That invocation drew visible irritation from senators and media coverage, and has become the focal point of discussions about accountability and transparency in government contracting.
Allegations, reported contract values and the DPWH response
Media and government records presented at hearings and in government complaint platforms list dozens of flood-control contracts tied to Wawao Builders. Some public summaries report figures such as 58 projects totaling about PHP 4.2 billion (completed) and other counts mentioning roughly 85 projects in Bulacan worth around PHP 5 billion, though those numbers vary among sources and remain subject to verification by investigators. DPWH officials have acknowledged suspicious entries and said they will pursue appropriate legal steps if wrongdoing is confirmed.
Why this matters — scale and public impact
The flood-control program at issue is meant to protect communities from damaging floods. If projects were recorded but not executed properly, the consequences include wasted public funds, inadequate protection for flood-prone areas, and possible damage to public trust. Lawmakers say the pattern—if proven—could amount to large-scale anomalous spending and urged rapid audits and legal action where necessary. Officials from the DPWH and other agencies have signaled investigations are ongoing.
Public reaction and media coverage
Arevalo’s silence at the hearing has generated significant public conversation and social media reaction, including memes and opinion pieces—reflecting both public frustration and the viral nature of the hearings. Several outlets covered not only the facts presented but also the mood in the committee room as senators pressed contractors for clearer answers.
