Unit-cost benchmark · Flood wall / dike / revetment, cost per linear meter (flood control structure)

₱122,024 per linear m= 0.8x the Region II median (n=146)

Contract cost ₱96,398,940 ÷ 790 linear m read from the DPWH title (“Sta. 0+000-Sta. 0+790”; station range length (Sta. a+b to c+d)). National percentile: 50. Higher unit cost can have legitimate causes (terrain, design, scope not stated in the title); this is a comparison, not a finding. Methodology
