Contractor Concentration (Flood Control)

A contractor holds a very large share of flood-control contract value in a district or province.

This is a statistical anomaly or indicator worth examining — not proof of wrongdoing, fraud, or corruption against any person.

Indicator: J G ORANZA CONST received 41.9% (₱825.86M of ₱1.97B) of recorded flood-control contract value in South Cotabato 1st District Engineering Office across 28 contracts and 12 contractors, above the 40% concentration threshold (HHI 0.206). This may be due to the contractor's strong track record or capacity in the area.

Possible Innocent Explanations

  • Dominant local contractor with equipment already in the area
  • Emergency or accelerated procurement after a disaster
  • Small number of qualified flood-control firms in the province
  • This may be due to the contractor's strong track record or capacity in the area.
