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 22D00086 and 23D00076 have near-identical descriptions about 899 m apart (funding years 2022, 2023; ₱144.75M, ₱96.50M). Worth checking whether they cover the same works. It is possible that the second project is a continuation or expansion of the first, or covers a different segment not clearly labeled in the title.

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 referring to 'Construction of River Protection Structure' at Barangay Maahas, Los Baños, Laguna. The only differences are the spelling out of 'Barangay' and the addition of 'Package A' in the second title, which per rule guidance does not count as a distinguishing marker if the other title has no package/phase marker. The projects are about 899 meters apart, which is above the 100m threshold, but the rule is triggered for near-identical titles within the same municipality. There is no evidence in the packet that these are clearly distinct works (e.g., different sections, phases, or sites named). Innocent explanations such as a continuation or expansion of the same project in a new year are plausible but do not block publishing.
