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 22AJ0011 and 23AJ0044 have near-identical descriptions about 1 m apart (funding years 2022, 2023; ₱49.00M, ₱47.57M). Worth checking whether they cover the same works. It is possible that the second project is a continuation or extension of the first, or that additional funding was allocated for further works at the same site.

How this was checked

publish · confidence 0.98

Model: gpt-4.1

Prompt: v4.1

Checked: October 22, 2026

The two project titles are near-identical, differing only in the use of 'Brgy.' versus 'Barangay', which is not a distinguishing marker per the rule. Both projects are at the same coordinates (1 meter apart), in the same barangay, and describe the same type of work along the same river. The only difference is the funding year and contractors. There are no phase, package, section, or other location markers that would distinguish them as separate works. The evidence is complete and meets the rule's criteria for publishing.
