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 23CC0123 and 24CC0140 have near-identical descriptions about 505 m apart (funding years 2023, 2024; ₱77.20M, ₱67.55M). Worth checking whether they cover the same works. It is possible that the second project is a continuation or expansion of the first, or covers a different segment not clearly labeled in the title.

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, both referring to flood mitigation structures at/along Barangay Frances, Calumpit, Bulacan, with no distinguishing phase, package, section, or site markers. The only differences are minor wording ('along' vs 'at', 'structures' vs 'structure', and 'Barangay' vs none), which are not distinguishing per the rule. The projects are about 505 meters apart and funded in consecutive years, which fits the pattern of possible duplicate or overlapping works. All required record details and URLs are present.
