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 24DL0015 and 23DL0083 have near-identical descriptions about 86 m apart (funding years 2023, 2024; ₱19.60M, ₱24.50M). Worth checking whether they cover the same works. It is possible that the second contract is a continuation or extension of the first project, but this is not labeled in the titles.

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 with no distinguishing markers or place names that would indicate different works. The locations are only 86 meters apart, and both are for 'Construction of Breakwater' in Alabat, Quezon, funded in consecutive years with the same contractor. This fits the rule's criteria for a potentially duplicate or overlapping project.
