Awards Very Close to the Budget Ceiling
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: Negros Occidental 1st District Engineering Office awarded 74 of 78 recorded flood-control contracts (94.9%) at 99.5% or more of their Approved Budget for the Contract, versus 70.4% for flood-control contracts nationwide (24.5 percentage points higher; binomial p = 6.6e-08), across 26 contractors. Source: DPWH / Sumbong sa Pangulo contract records; each contract is listed below. This pattern may result from consistently accurate cost estimates or competitive bidding practices.
Only contractors and government agencies named in public procurement records are shown. Private individuals are not named.
