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: ROSBILL CONST AND SUPPLY received 33.4% (₱403.59M of ₱1.21B) of recorded flood-control contract value in Davao de Oro 2nd District Engineering Office across 17 contracts and 6 contractors, at or above the 25% share threshold (HHI 0.259). This may be due to the contractor's strong track record or specialization in flood-control projects in the area.
