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 24HL0036 and 23HL0053 have near-identical descriptions about 1247 m apart (funding years 2023, 2024; ₱45.08M, ₱49.00M). Worth checking whether they cover the same works. This may be a continuation or extension of the same river control project funded in two phases.

Satellite comparison for public reference — not proof of completion or non-completion.

Imagery may not show small or linear works; no visible change is not evidence of wrongdoing.

How this was checked

publish · confidence 0.95

Model: gpt-4.1

Prompt: v4.1

Checked: October 22, 2026

The titles are completely identical with no distinguishing markers, and the projects are only about 1.2 km apart in the same city, funded in consecutive years. This fits the rule's publish criteria for possible duplicate or overlapping works. Innocent explanations (such as a continuation or extension of the same project) are plausible but do not block publication.
