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: CM TAN CONST received 28.2% (₱1.05B of ₱3.73B) of recorded flood-control contract value in AGUSAN DEL SUR across 43 contracts and 12 contractors, at or above the 25% share threshold (HHI 0.123). This may be due to the contractor's strong track record or specialization in flood-control projects in the area.
