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 22CI0057 and 22CI0058 and 22CI0119 have near-identical descriptions at the same coordinates (funding year 2022; ₱23.75M, ₱24.30M, ₱24.28M). Worth checking whether they cover the same works. These may be adjacent or sequential segments of riverwall construction, or a single project split into multiple contracts for implementation reasons.

How this was checked

publish · confidence 0.85

Model: gpt-4.1

Prompt: v4.1

Checked: October 22, 2026

All three contracts are at identical coordinates, funded in the same year, with near-identical titles. The only differences in the titles are the addition of station markers and the mention of an extra barangay (Marcos Village) and riverwall segment in two of the titles. However, one contract (22CI0057) is generic and does not specify a segment or multiple barangays, while the other two (22CI0058, 22CI0119) specify overlapping or adjacent segments and both barangays. There is no clear phase/section/lot marker that would definitively distinguish them as separate works, and the overlap in location and scope is substantial. This fits the guidance for publishing as a possible duplicate or overlapping funding.
