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 22OE0028 and 24OE0180 have near-identical descriptions about 640 m apart (funding years 2022, 2024; ₱47.48M, ₱96.22M). Worth checking whether they cover the same works. It is possible that the second project is a continuation or expansion of the first, or addresses additional needs in the same area.

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 both refer to 'Zone 1-12, Tondo, Manila City' without any distinguishing markers such as phase, package, or different locations. The projects are about 640 meters apart and funded in different years, which fits the rule's criteria for a potentially duplicated or overlapping scope. All necessary records and URLs are present.
