Cross-Source Mismatch (PhilGEPS vs DPWH)

Linked PhilGEPS award amount or awardee disagrees with Sumbong contract row.

This is a statistical anomaly or indicator worth examining — not proof of wrongdoing, fraud, or corruption against any person.

Indicator: PhilGEPS award 22PA0104 lists ₱46.56M to 739 BUILDERS, while DPWH records contract 22PA0104 at ₱49.50M to 739 BUILDERS. The contract amount may have increased after the initial award due to approved variation orders or scope changes.
