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 23MB0075 and 22MB0023 have near-identical descriptions about 516 m apart (funding years 2022, 2023; ₱86.85M, ₱88.42M). Worth checking whether they cover the same works. It is possible that these are two phases or extensions of the same revetment project funded in consecutive years.

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 refer to the construction of a revetment along the Sinawal River in General Santos City, and there are no distinguishing markers such as phase, package, section, or different locations. The only difference is the word 'Concrete' in one title, which is not a distinguishing marker per the guidelines. The projects are about 516 meters apart, which is above the 100m threshold, but the rule allows for near-identical titles within the same municipality. The evidence is complete and checkable.
