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 24OC0088 and 24OC0049 have near-identical descriptions about 442 m apart (funding year 2024; ₱48.25M, ₱96.50M). Worth checking whether they cover the same works. These may be adjacent or sequential works along the same creek, or one could be an extension of the other.

How this was checked

publish · confidence 0.85

Model: gpt-4.1

Prompt: v4.1

Checked: October 22, 2026

The two project titles are near-identical, both refer to the same creek and barangay, and are funded in the same year. The only difference is that one specifies 'near Valley 8', which is not a clear phase/section/segment marker but a local area within the same barangay. There are no phase/package/lot or section markers, and the distinguishingMarkers field is empty. The distance (442m) is above the rule's 100m threshold, but the high title similarity and overlapping location make this worth publishing as a possible duplicate or overlapping scope. Innocent explanation: the projects could cover adjacent or sequential stretches of the same creek, or one is a continuation/extension of the other.
