Public Works Minister Dean Macpherson warns of the sophisticated tactics used by the construction mafia in South Africa, which have disrupted over R63bn in infrastructure projects.

The newly approved Integrated Social Facilitation Framework aims to combat this organised crime and protect vital construction efforts.

He said they were incredibly sophisticated, and often they are politically connected.

"They were learning how to embed themselves, not only through open violence, but through subcontracting arrangements, local participation structures, security contracts, front companies and self-appointed community representatives."

DA MP Dean Macpherson said the launch of the National Built Environment and Construction Safety Framework was an important step towards strengthening safety, accountability and collaboration across the built environment ecosystem.
