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 24JE0032 and 23JE0075 have near-identical descriptions about 43 m apart (funding years 2023, 2024; ₱29.37M, ₱78.40M). Worth checking whether they cover the same works. It is possible that the second project is an expansion or continuation that added an access road to the original river control structure.

How this was checked

publish · confidence 0.93

Model: gpt-4.1

Prompt: v4.1

Checked: October 22, 2026

The two project titles are near-identical, both referring to the construction of a river control structure along Lenienza Creek in Barangay/Brgy. Tiguma, Pagadian City, Zamboanga del Sur. The only differences are the inclusion of 'with Access Road' in the second title and minor wording variations ('Barangay' vs 'Brgy.'). There are no phase, package, section, or other distinguishing markers, and both are at nearly the same coordinates (43 meters apart). This fits the rule's criteria for a potentially duplicate or overlapping project, especially as one title simply adds an access road to the other, which could mean the same or overlapping works. Innocent explanations (such as a legitimate continuation or expansion) are possible but do not block publication.
