Unit-cost benchmark · Pumping station, cost per station (new construction)

₱23,488,443 per station= 0.6x the National Capital Region median (n=119)

Contract cost ₱23,488,443 ÷ 1 station read from the DPWH title (“PUMPING STATION”; single new pumping station named in title). National percentile: 35. Higher unit cost can have legitimate causes (terrain, design, scope not stated in the title); this is a comparison, not a finding. Methodology

Low flood hazard · NCR, Third District
