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. It is possible that these are separate flood control projects in different sections or sitios, each requiring its own contract.

How this was checked

publish · confidence 0.98

Model: gpt-4.1

Prompt: v4

Checked: October 22, 2026

This is a C5 indicator, and the code has already confirmed that ≥3 contracts in the cluster are in the same municipality, with all contracts awarded to the same contractor and DEO, started within 91 days, and each just under the ₱50M threshold. The titles refer to different sitios/sections/barangays, which is expected for C5 and does not invalidate the indicator. There is no evidence of a data artifact.
