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. It is possible that one project built new slope protection while the other repaired or upgraded an existing section nearby.

How this was checked

publish · confidence 0.85

Model: gpt-4.1

Prompt: v4.1

Checked: October 22, 2026

The titles are near-identical, both referring to slope protection along Ermitaño Creek in San Juan City, with no distinguishing markers such as phase, section, or different locations. The only difference is 'Rehabilitation' vs 'Construction', which could indicate either a continuation, upgrade, or possible overlap. The projects are about 1 km apart, which is not enough to clearly distinguish them as separate works along a long creek, especially since both are in the same city and refer to the same creek. The evidence is complete and meets the rule's thresholds.
