Indicator C5 — Pattern Consistent with Contract Splitting

AI-verified / Na-verify ng AI Data as of October 21, 2026

Pattern Consistent with Contract Splitting

Multiple similar contracts to the same contractor/DEO just under a threshold in a short window.

This is a statistical anomaly or indicator worth examining — not proof of wrongdoing, fraud, or corruption against any person.

Indicator: 6 contracts awarded to CS CONST AND SUPPLY INC FORMERLY: CS CONST AND SUPPLY by the same office started within 91 days, each between ₱42.5M and ₱50M (just under the ₱50M threshold), with 3 in the same municipality. These may be separate flood control projects in different locations within the same area, each requiring its own contract.

Checked: October 22, 2026

This is a textbook C5 case: six contracts, all just under the ₱50M threshold, awarded to the same contractor and DEO, with start dates within 91 days. The titles show different sitios, barangays, and river sections, which is expected for C5 (the rule is designed to catch clusters of near-threshold contracts in one municipality, not duplicate works). The data is complete and the public can verify each contract via the provided URLs.
