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 23CF0031 and 25CF0004 have near-identical descriptions about 299 m apart (funding years 2023, 2025; ₱72.37M, ₱34.13M). Worth checking whether they cover the same works. The second project may be a continuation or expansion of the first, or may cover additional works not specified in the first title.

How this was checked

publish · confidence 0.80

Model: gpt-4.1

Prompt: v4.1

Checked: October 22, 2026

The two project titles are nearly identical and refer to the same barangay and river, with one title specifying a station range (Sta. 25+760.00-Sta. 26+048.40) and the other omitting it. According to the rule, if one title has a phase/station marker and the other does not, this is a classic 'unlabelled twin' case and should be published. The projects are about 299 meters apart, which is within a plausible range for overlapping or repeated works. All required records and URLs are present.
