Unit-cost benchmark · Road, cost per km (preventive maintenance / overlay)

₱78,007,368 per km= 1.7x the Region XI median (n=143)

Contract cost ₱134,874,739 ÷ 1.729 km read from the DPWH title (“K1514+103 - K1515+832”; K-post / station range length). National percentile: 94. Higher unit cost can have legitimate causes (terrain, design, scope not stated in the title); this is a comparison, not a finding. Methodology
