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: CARTESIAN BUILDERS CORP FORMERLY: CARTESIAN BUILDERS received 47.5% (₱242.67M of ₱510.86M) of recorded flood-control contract value in DINAGAT ISLANDS across 15 contracts and 9 contractors, at or above the 25% share threshold (HHI 0.291). This may be due to the contractor's strong track record or specialization in flood-control projects in the area.
Only contractors and government agencies named in public procurement records are shown. Private individuals are not named.
