The Construction Industry Federation C-19 induction programme is designed to protect construction industry members, families and communities whilst allowing them to work safely. Its purpose is to ensure that everyone working on a construction project understand how to prevent the spread of COVID-19 in the workplace. When a member completes the induction, they will receive a digital card, on their phone, confirming that they have successfully completed the programme. They will need this to access a site so will always have to have it ready. Have a look over here for more information.
