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 22HL0039 and 23HL0048 have near-identical descriptions about 44 m apart (funding years 2022, 2023; ₱40.71M, ₱49.00M). Worth checking whether they cover the same works. It is possible that the first project was for rehabilitation of an existing structure, while the second was for new construction in the same area.

How this was checked

publish · confidence 0.85

Model: gpt-4.1

Prompt: v4.1

Checked: October 22, 2026

The two projects are only 44 meters apart, have near-identical titles referring to the same river control structure and upstream location in Bayawan City, and are funded in consecutive years. There are no distinguishing markers such as different phases, sections, or barangays. The only differences are 'Rehabilitation' vs 'Construction' and 'Upstream B' vs 'Upstream', which do not clearly indicate separate works. This fits the rule's criteria for a potentially duplicate or overlapping project.
