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 21HE0156 was awarded at 100.00% of its ABC. Across its 32 recorded contracts, QUIRANTE CONST CORP FORMERLY: QUIRANTE CONST was awarded at ≥99.5% of ABC 31 times (96.9%), versus 70.4% for flood-control contracts overall. This may 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 at the legal limit and unusual. The contractor has a very high rate (96.9%) of contracts awarded at or near the ABC, much higher than the baseline for flood-control contracts (70.4%). All relevant figures and source URLs are present, and the indicator can be described neutrally.
