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: Nueva Vizcaya District Engineering Office awarded 60 of 64 recorded flood-control contracts (93.8%) at 99.5% or more of their Approved Budget for the Contract, versus 70.4% for flood-control contracts nationwide (23.3 percentage points higher; binomial p = 4.1e-06), across 19 contractors. Source: DPWH / Sumbong sa Pangulo contract records; each contract is listed below. This pattern may result from consistently competitive bidding or careful cost estimation in the district.
Only contractors and government agencies named in public procurement records are shown. Private individuals are not named.
