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 23BG0075 and 24BG0070 have near-identical descriptions about 517 m apart (funding years 2023, 2024; ₱52.83M, ₱96.49M). Worth checking whether they cover the same works. These may be consecutive phases or extensions of the same flood control project funded in different years.

How this was checked

publish · confidence 0.95

Model: gpt-4.1

Prompt: v4.1

Checked: October 22, 2026

The two project titles are near-identical, with only the word 'at' differing, and both refer to the same barangay and municipality. There are no distinguishing markers such as phase, package, section, or different place names. The projects are about 517 meters apart, which is above the 100m threshold, but the titles do not specify different locations within the barangay. The funding years are consecutive, which could indicate a continuation or expansion, but this is not explicitly stated in the titles. The evidence is complete and sufficient for public review.
