Indicator C2 — Awards Very Close to the Budget Ceiling

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

Awards Very Close to the Budget Ceiling

Contract cost is at or above 99.5% of ABC from Sumbong.

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

Indicator: contract 23BH0136 was awarded at 99.92% of its ABC. Across its 28 recorded contracts, V B MANUBAY CONST was awarded at ≥99.5% of ABC 28 times (100.0%), versus 70.4% for flood-control contracts overall. It is possible that the contractor consistently bids just below the ABC to maximize their chances of winning while complying with procurement rules.

How this was checked

publish · confidence 0.98

Model: gpt-4.1

Prompt: v4

Checked: October 22, 2026

The contract was awarded at 99.92% of its ABC, which is highly unusual and above the 99.5% threshold. The contractor has a perfect record (28/28) of winning contracts at or above this threshold, which is much higher than the baseline for flood-control contracts (70.4%). All relevant figures and source links are present, and the evidence is sufficient for public review.
