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 23IL0040 and 22IL0087 have near-identical descriptions about 147 m apart (funding years 2022, 2023; ₱49.00M, ₱48.94M). Worth checking whether they cover the same works. These may be sequential phases or expansions of the same flood control project funded in different years.

How this was checked

Model: gpt-4.1

Prompt: v4.1

Checked: October 22, 2026

The titles are near-identical and refer to the same general location (Canturing, Maasin City, Southern Leyte) with no distinguishing phase, package, or section markers. The only differences are generic terms ('structures', 'river', 'control'), which do not clearly indicate different works. The projects are about 147 meters apart and funded in consecutive years, which could indicate either a continuation or possible double funding. All required records and fields are present.
