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 22OI0039 and 23OI0033 have near-identical descriptions about 238 m apart (funding years 2022, 2023; ₱49.00M, ₱49.00M). Worth checking whether they cover the same works. It is possible that the second project is a continuation or expansion of the first, or covers a nearby section not specified in the title.

How this was checked

publish · confidence 0.95

Model: gpt-4.1

Prompt: v4.1

Checked: October 22, 2026

The titles are near-identical, with only the word 'at' differing, and there are no distinguishing markers such as phase, package, section, or different place names. The projects are about 238 meters apart, which is above the strict 100m threshold but still close enough to warrant public attention, especially since both are for the same type of work, at the same river and city, by the same contractor, in consecutive years. Innocent explanations are plausible (e.g., continuation or expansion of works), but the pattern is genuinely unusual and worth public scrutiny.
