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 23DC0059 and 22DC0092 have near-identical descriptions about 1172 m apart (funding years 2022, 2023; ₱67.55M, ₱39.20M). Worth checking whether they cover the same works. These may be separate flood control works at different points along the Bugaan River or its outfall, funded in different years.

How this was checked

publish · confidence 0.85

Model: gpt-4.1

Prompt: v4.1

Checked: October 22, 2026

The titles are highly similar and refer to flood mitigation works along Bugaan River/Bugaan East in Laurel, Batangas, funded in consecutive years. There are no explicit distinguishing markers such as phase, package, or section numbers, nor do the titles specify clearly different sites (e.g., different barangays or segments). The difference in wording ('River' vs 'East', 'Structure' vs 'Structures (Outfall)') could indicate different parts or types of works, but this is not definitive. The distance (1172 m) is above the 100 m threshold, but the rule is for near-duplicate titles within the same municipality, and the code has already flagged this as a valid case. Innocent explanations are plausible but do not block publishing.
