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 24CC0421 was awarded at 100.00% of its ABC. Across its 48 recorded contracts, TOPNOTCH CATALYST BUILDERS INC was awarded at ≥99.5% of ABC 45 times (93.8%), versus 70.4% for flood-control contracts overall. This could be due to highly competitive bidding or precise cost estimation.

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 much higher rate of near-ABC awards than the baseline, and all relevant figures and record links are present. Innocent explanations are possible (e.g., competitive bidding or precise cost estimation), but this does not block publication.
