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 22GA0034 and 23GA0106 have near-identical descriptions at the same coordinates (funding years 2022, 2023; ₱49.00M, ₱49.00M). Worth checking whether they cover the same works. It is possible that the second contract is a continuation or expansion of the previous year's project at the same site.

How this was checked

publish · confidence 0.95

Model: gpt-4.1

Prompt: v4.1

Checked: October 22, 2026

Both project titles refer to the construction of a revetment wall along the Aklan River at Barangay Mobo, Kalibo, Aklan, with identical coordinates and no distinguishing markers such as phase, package, section, or different locations. The only difference is the addition of 'Flood Control' in the second title, which does not specify a different work or location. This fits the rule's criteria for a potentially duplicate or overlapping project.
