Building Responsibly developed these Principles to serve as the global standard on worker welfare for the engineering and construction industry. They address key areas of worker vulnerability to raise standards and level the playing field so that competitiveness is not at the expense of the worker. Given differing local and national requirements and external guidelines, these Principles establish a common, global baseline for the treatment of workers in the engineering and construction industry. By collectively committing to and promoting these Principles, we can foster a business environment that advances the safety, security, and welfare of all people—especially those working in the construction sector.
