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 24NE0025 and 23NE0028 have near-identical descriptions about 381 m apart (funding years 2023, 2024; ₱57.19M, ₱9.79M). Worth checking whether they cover the same works. One project may be a continuation or expansion 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 and refer to the same bridge/area (Tag-iho Bridge I, Tag-abaca, Basilisa, Dinagat Islands), with only minor wording differences (Bridge/Br., Barangay). There are no phase, package, or section markers, and the only differences are generic or spelling/abbreviation variants. The projects are about 381 meters apart, which is above the strict 100m threshold, but the high title similarity and matching location names make this a plausible case of possible double funding or continuation without clear labelling. Innocent explanation is possible (e.g., one is a continuation or expansion), but the indicator is worth showing.
