Document background
The Certificate of Partial Completion is a critical document in Swiss construction projects, used when a definable portion of the contracted works has been completed but the entire project is still ongoing. This certificate, regulated under Swiss law and particularly the Swiss Code of Obligations and SIA Norm 118, serves multiple purposes: it triggers payment milestones, initiates warranty periods for completed works, and provides formal documentation of project progress. The document is typically issued following thorough inspections and agreement between the contractor and client/employer, often with involvement from architects or engineers. It must clearly define the scope of completed works, their compliance with specifications, and any outstanding items or defects to be addressed. The Certificate of Partial Completion is particularly important in large-scale projects where work is completed in phases or where different contractors are involved in different aspects of the construction.
