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 23OB0098 and 23OB0097 have near-identical descriptions about 99 m apart (funding year 2023; ₱3.72M, ₱13.92M). Worth checking whether they cover the same works. One contract may cover a broader area ('and vicinity'), while the other focuses on a specific section.

How this was checked

publish · confidence 0.95

Model: gpt-4.1

Prompt: v4.1

Checked: October 22, 2026

The two project titles are nearly identical, with the only difference being the addition of 'and vicinity' in one title. There are no phase, package, section, or place markers that distinguish them as separate works. Both are in the same barangay, funded in the same year, by the same contractor, and are only 99 meters apart. This fits the criteria for a potentially duplicate or overlapping project worth public attention.
