Indicator C3 — Duplicate or Near-Duplicate Projects

AI-verified / Na-verify ng AI Data as of October 21, 2026

Duplicate or Near-Duplicate Projects

Very similar descriptions within ~100m or identical coordinates across contracts/years.

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

Indicator: contracts 24GN0015 and 22GN0063 have near-identical descriptions about 107 m apart (funding years 2022, 2024; ₱70.17M, ₱49.00M). Worth checking whether they cover the same works. It is possible that these are sequential or complementary works addressing different aspects of the same seawall.

How this was checked

publish · confidence 0.85

Model: gpt-4.1

Prompt: v4.1

Checked: October 22, 2026

The titles are near-identical, both referring to construction along the Valladolid Seawall in the same municipality, with no distinguishing phase, package, or location markers. The only difference is 'Flood Mitigation' vs 'Bank Protection', which are often used interchangeably in DPWH project naming and do not clearly indicate different works. The projects are about 107 meters apart, within the threshold for possible overlap or duplicate funding. All necessary records and URLs are present.
