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: RITCHE-NATHALIE BUILDERS & GEN MERCHANDISE received 34.1% (₱178.62M of ₱523.87M) of recorded flood-control contract value in Misamis Occidental 1st District Engineering Office across 14 contracts and 9 contractors, at or above the 25% share threshold (HHI 0.194). This may simply reflect that the contractor is particularly active or competitive in this district.
Only contractors and government agencies named in public procurement records are shown. Private individuals are not named.
