Unit-cost benchmark · School building, cost per classroom (new school building)

₱2,430,811 per classroom= 1.1x the Region IV-A median (n=665)

Contract cost ₱19,446,487 ÷ 8 classroom read from the DPWH title (“8 CLASSROOM”; classroom count in title). National percentile: 78. Higher unit cost can have legitimate causes (terrain, design, scope not stated in the title); this is a comparison, not a finding. Methodology
