Large-scale construction projects are currently taking place across Shanghai, drawing on huge numbers of workers who operate in continuous shifts – often across several sites. In an effort to facilitate the organisation of this vast workforce, the designer has produced a series of workers’ uniforms that clearly indicate the person’s identity, skills and level of experience through a graphic system. Each trade is represented by a specific colour, a transparent chest pocket allows the worker’s ID to be immediately visible, and removable stripes and numbers allow the worker to indicate their level of experience and what team they are working with on any given day.
