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

₱182,005 per linear m= 0.8x the National Capital Region median (n=45)

Contract cost ₱27,300,819 ÷ 150 linear m read from the DPWH title (“STA. 0+300 TO STA. 0+450”; station range length (Sta. a+b to c+d)). National percentile: 70. Higher unit cost can have legitimate causes (terrain, design, scope not stated in the title); this is a comparison, not a finding. Methodology
