Indicator C2 — Bid-Ceiling Hugging

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

Bid-Ceiling Hugging

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 20G00101 was awarded at 100.00% of its ABC. Across its 22 recorded contracts, IBC INTERNATIONAL BUILDERS CORP was awarded at ≥99.5% of ABC 21 times (95.5%), versus 70.4% for flood-control contracts overall. This may result from highly competitive bidding where the winning bid matches the ABC exactly.

How this was checked

publish · confidence 0.98

Model: gpt-4.1

Prompt: v4

Checked: October 22, 2026

The contract was awarded at exactly 100% of the ABC, which is unusual and meets the rule's threshold. The contractor has a very high rate (95.5%) of winning contracts at or above 99.5% of ABC, much higher than the baseline for flood-control contracts (70.4%). All relevant figures and record links are present, and the evidence is sufficient for public review.
