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 23DD0070 and 22DD0044 have near-identical descriptions about 1121 m apart (funding years 2022, 2023; ₱76.23M, ₱93.61M). Worth checking whether they cover the same works. It is possible that the two contracts cover different sections of the Lawaye River, with one specifically in Barangay Poctol and the other covering a broader or adjacent area.

How this was checked

publish · confidence 0.80

Model: gpt-4.1

Prompt: v4.1

Checked: October 22, 2026

The only distinguishing marker is 'Barangay Poctol' in the first title, while the second title is more general ('San Juan, Batangas'). Since the second title does not specify a different barangay or section, and the first is a subset of the second, this fits the guidance for publishing: one title is the other plus a specific place, which means the works may overlap or be continuations. The distance (1121m) is within the same river stretch and does not clearly indicate separate works. Innocent explanation is plausible but does not block publishing.
