The Gustav Ende (GE) method is designed to provide a highly accurate, granular view of the time required for technical installations. Unlike simpler estimation methods, the GE norms are often composite: Unit-Based Timing
The Gustav Ende table belongs to the family of . Its direct intellectual heirs include:
These times represent the "gross time" (bruto tijd), which includes the labor of all direct and indirect personnel on-site. Component / System Norm Time (min/m or unit) DN-50 Steel Pipe (with insulation) DN-100 Steel Pipe (with insulation) DN-150 Steel Pipe (with insulation) (Ø 50 mm) Standard Toilet (WC) 180 min/unit Built-in Toilet (WC inb.) 240 min/unit 120 min/unit Important Application Factors Total Calculation:
For those uninitiated in the denser corners of technical literature, Gustav Ende is not a household name, but in the niche of industrial assembly and structural planning, his methodology is akin to scripture. This review looks at whether these tables are merely academic exercises or practical tools for the modern site.
