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 22OC0135 and 23OC0008 have near-identical descriptions about 314 m apart (funding years 2022, 2023; ₱39.20M, ₱73.74M). Worth checking whether they cover the same works. It is possible that the second contract is a planned continuation or extension of the first project.

The only distinguishing marker is that one title is labeled 'Phase II' while the other is unlabelled. Both projects are for the construction of a revetment wall along Bangkal Creek in Barangay Bangkal, Makati City, funded in consecutive years, and are located only 314 meters apart. According to the rule guidance, if the only difference is a phase marker and the other has none, this should be published as a potential unlabelled twin or continuation.
