Gewerke

Gewerke is a term used in the construction industry, particularly in German-speaking countries, to refer to the trades or work packages that make up a building project. A Gewerke represents a defined scope of work that is typically carried out by a specialized contractor or team of craftsmen. The concept helps organize procurement, scheduling, budgeting, and quality control by dividing the project into manageable, interface-controlled segments.

Typical examples of Gewerke include structural works (Rohbau), interior finishing and partitioning (Ausbau), electrical installations (Elektro), sanitary and heating systems (Sanitär/Heizung), ventilation and air conditioning (HLK/Klima), roofing (Dachdecker), windows and façade elements, carpentry (Tischlerei/Schreiner), plastering and painting, tiling, and metalwork. The exact list depends on the project type, country, and contractual form.

In practice, each Gewerke is defined in the project documentation and may be contracted separately (Gewerkvertrag) or as part of a general contractor’s scope. Prices and schedules are established for each Gewerke in the Leistungsverzeichnis or Leistungsbeschreibung, outlining the required performance and interfaces with other trades. Coordination is essential to manage interfaces between Gewerke, prevent clashes, and ensure timely handover to subsequent trades.

The Gewerke concept supports risk management and accountability by clarifying responsibilities, costs, and deadlines. It is widely used in Germany, Austria, and Switzerland, and is compatible with modern methods such as BIM, which enhances cross-trade coordination and planning across Gewerke.
