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 23OD0184 and 24OD0265 have near-identical descriptions about 460 m apart (funding years 2023, 2024; ₱24.19M, ₱23.96M). Worth checking whether they cover the same works. It is possible that the second contract is a continuation or extension of the drainage system started in the first contract.

How this was checked

publish · confidence 0.95

Model: gpt-4.1

Prompt: v4.1

Checked: October 22, 2026

The two contracts have identical titles with no distinguishing markers, are located in the same barangay, and are funded in consecutive years. The distance between them (460 m) is above the strict threshold for 'nearby', but the rule is designed to catch possible double funding or continuation of works under near-identical titles. There is enough information for public checking, and the pattern is genuinely unusual.
