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 23BH0059 was awarded at 99.99% of its ABC. Across its 33 recorded contracts, JWU CONST AND SUPPLY was awarded at ≥99.5% of ABC 33 times (100.0%), versus 70.4% for flood-control contracts overall. This pattern may result from consistently competitive bidding or precise cost estimation.

Model: gpt-4.1

Prompt: v4

Checked: October 22, 2026

The contract was awarded at 99.99% of ABC, which is highly unusual and above the 99.5% threshold. The contractor has a perfect record (33/33) of contracts awarded at or above 99.5% of ABC, which is much higher than the baseline for flood-control contracts (70.4%). All relevant figures and source URLs are present, and the evidence is sufficient for public review.
