CRIMINAL syndicates known as the construction mafia have brought South Africa’s infrastructure sector to its knees, hijacking over 180 projects and causing an estimated R63-billion in economic damage, according to National Treasury.
These groups, often operating under the guise of community forums, use threats, extortion, and violence to force their way into government tenders and construction contracts.
While law enforcement has begun to respond, 745 extortion cases have been reported, and 240 arrests have been made since November 2024. Public Works and Infrastructure Minister Dean Macpherson admits that this is only the beginning.
“We are turning the tide,” he said recently, but warned that corruption remains deeply entrenched in procurement systems and local government supply chains.
Against this backdrop, experts at WWISE (Worldwide Industrial and Systems Engineers) are calling for the widespread adoption of ISO 37001, a tool they believe could play a critical role in fortifying the sector from within.
“This may be South Africa’s last line of defence if we want to build infrastructure without bribery or intimidation,” says Muhammad Ali, MD at WWISE.
“ISO 37001 helps organisations embed ethical conduct into every stage of a project, from procurement to execution, making it harder for criminal networks to manipulate the system.”
ISO 37001 is not just a policy; it’s a globally recognised standard, or in other words, a formalised, best-practice framework developed by international experts to help organisations detect and prevent bribery. As a standard, ISO 37001 establishes a uniform, auditable benchmark for anti-bribery management across industries, enabling companies and governments to foster transparency, demonstrate accountability, and safeguard their reputations.
“The standard requires top-level leadership commitment, risk assessments, strict financial controls, and confidential reporting systems,” explains Ali. “It doesn’t just help companies avoid corruption, it actively reshapes their culture.”
Corruption in the construction industry not only inflates costs but also endangers lives. Ali notes that criminal infiltration has led to shutdowns, missed milestones, and Service Level Agreement (SLA) penalties. “We’ve seen cases where construction mafia threats delayed entire projects, with local authorities often turning a blind eye, or worse, getting a cut,” he says.
ISO 37001 offers practical safeguards. It ensures that tender documents are traceable and auditable. It enforces ethical vetting of suppliers and enshrines whistleblower protection through encrypted systems. “You can’t bribe your way into a tender process governed by ISO 37001,” says Ali.
Yet adoption of the standard remains frustratingly limited. “Most construction companies in South Africa haven’t implemented it,” Krause says. “The only time we see ISO 37001 considered is when international investors require it,” Ali adds that public sector resistance is particularly troubling. “The fear is that ISO 37001 will expose misconduct,” he says. “But that’s the point. The excuses, ‘too complex’, ‘too bureaucratic’, don’t hold water. This standard can be adapted to any organisation.”
He points to a compelling case in Iraq, where a security company under attack from corrupt government officials used ISO 37001 to clear its name. “The audits exposed the wrongdoing, and the officials were jailed. That’s the power of a strong, standardised anti-bribery framework.”
For smaller contractors, who are often the most vulnerable to extortion, ISO 37001 can provide an essential shield if supported by law enforcement. “The problem may not be with the company,” Ali warns, “but when it needs support, the authorities often fall short.”
