Simplified input
Length, DN, country and condition are the only public inputs. All other values resolve server-side from governed protected defaults. The public client cannot submit arbitrary PACE parameters.
Condition mapping
- Favourable / straightforward: Flat or straight working corridor with stable cohesive ground. Terrain: Flat / straight corridor Ground: Dense Cohesive Soil
- Typical: Rolling terrain with the protected ordinary-soil assumptions. Terrain: Rolling terrain Ground: Ordinary Soil
- Constrained: Constrained terrain with loose or saturated ground assumptions. Terrain: Norwegian hydropower default Ground: Loose / Saturated Soil
- Difficult: Complex alignment using the protected shored-excavation assumptions. Terrain: Complex mountainous alignment Ground: Shored Excavation
Regional cost basis
- Netherlands: Uses the governed France regional cost profile as the current continental European screening proxy.
- France: Uses the governed France regional cost profile.
- Norway: Uses the governed Norway regional cost profile.
- Canada: Uses the governed Canada regional cost profile.
- GCC: Uses the governed GCC regional cost profile.
Commercial presentation
The protected PACE result is calculated first. HAPI Lite then caps only the publicly displayed saving at 20% and adjusts the displayed HydroFoamer indication consistently. Full HAPI calculations are not changed.
Engineering exclusions
This screen does not establish alignment, sections, pressure, material, logistics, geotechnical conditions, specification or an Accepted Pipeline Basis. Those require Full HAPI review.
