About Dimacha

Independent oversight. Dual discipline. Trade-tested.

Dimacha Holdings (Pty) Ltd is an independent construction quality and compliance consultancy serving South Africa's utility and infrastructure sector. We provide Clerk of Works, quality assurance and contract compliance services on complex electrical, civil and building works — acting as the client's representative on site from first inspection through to closeout.

We report to the client, never the contractor. Findings are recorded exactly as found. Works are verified against Eskom distribution and transmission technical standards. Every inspection produces a defensible, dated written record. From our Free State base, we deploy to sites across South Africa.
