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 23OB0108 and 22OB0242 have near-identical descriptions about 1023 m apart (funding years 2022, 2023; ₱59.59M, ₱18.62M). Worth checking whether they cover the same works. These may be different phases or sections of slope protection works along the same creek, or one may be an upgrade of the other.

How this was checked

publish · confidence 0.85

Model: gpt-4.1

Prompt: v4.1

Checked: October 22, 2026

The titles are near-identical except for 'Rehabilitation' vs 'Construction', both refer to slope protection along Ermitaño Creek in San Juan City, and are about 1 km apart. There are no phase, package, section, or place markers distinguishing them further. The only difference is the type of work (rehabilitation vs construction), which could indicate either a continuation, a new section, or a possible overlap. The evidence is complete and meets the rule's criteria.
