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 24FK0047 and 23FK0089 have near-identical descriptions about 74 m apart (funding years 2023, 2024; ₱49.50M, ₱28.64M). Worth checking whether they cover the same works. It is possible that the second project is a continuation or extension of the first, but this is not labeled in the titles.

Satellite comparison for public reference — not proof of completion or non-completion.

Imagery may not show small or linear works; no visible change is not evidence of wrongdoing.

How this was checked

publish · confidence 0.95

Model: gpt-4.1

Prompt: v4.1

Checked: October 22, 2026

The two projects have near-identical titles with no distinguishing markers (no phase, package, section, or different place names), are located only 74 meters apart, and are funded in consecutive years. This fits the rule's criteria for a potentially duplicate or overlapping project. All necessary records and URLs are present for public checking.
