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

₱158,941 per linear m= 0.9x the Region IV-A median (n=19)

Contract cost ₱67,550,000 ÷ 425 linear m read from the DPWH title (“Sta. 3 + 675 - Sta. 4 + 100”; station range length (Sta. a+b to c+d)). National percentile: 64. Higher unit cost can have legitimate causes (terrain, design, scope not stated in the title); this is a comparison, not a finding. Methodology
