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

₱96,161 per linear m= 0.9x the Region XIII median (n=38)

Contract cost ₱46,541,858 ÷ 484 linear m read from the DPWH title (“STA.0+056.96 - STA.0+220.96; STA.0+000 - STA.0+160.00; STA.0+000 - STA.0+160.00”; station range length (Sta. a+b to c+d)). National percentile: 37. Higher unit cost can have legitimate causes (terrain, design, scope not stated in the title); this is a comparison, not a finding. Methodology
