The is a standardized reference used primarily in mechanical and electrical engineering to calculate the time and cost required for installation tasks. Developed by Swedish engineer Gustav Ende in the 1970s, this system provides "norm times" (standard durations) for installing specific components, measured in minutes per unit or per meter. Key Features of the Gustav Ende Table
Organizations like Techniek Nederland provide updated "Calculatietijdnormen" that have largely replaced the Gustav Ende method for current professional projects. Example Assembly Times (Indicative) Component Type Norm Time (Ploegminuten) Air Heater (up to 100kg) Air Heater (up to 150kg) Air Heater (up to 100kg) Normering van arbeid in de installatiebranche | TVVL tabel montage tijden conform gustav ende full
According to standard industry exports and available datasets: Component Type Size/Specification Norm Time (Minutes per Unit/Meter) ~3.6 min/m Steel Pipe (Insulated) ~5.4 min/m Steel Pipe (Insulated) ~7.2 min/m Air Heater (Luchtverhitter) < 100kg (3m height) Air Heater (Luchtverhitter) < 150kg (3m height) Air Heater (Luchtverhitter) < 400kg (3m height) Practical Application & Calculation The is a standardized reference used primarily in
