Years of experience
I brings over a decade of on-site construction expertise across utility-scale solar PV projects in South Africa, Botswana, Namibia, and Spain - with direct experience working on both EPC and Owner's Engineer (OE) sides. At Sturdee Energy, he served as the Owner's Engineer on a multi-year solar build in Botswana, overseeing full site-based construction delivery on behalf of the client and lenders. His technical scope spans full-cycle solar execution, including piling, tracker installation, HV and MV works, SCADA integration, and commissioning. He has managed piling programs exceeding 35,000 installations under strict survey tolerances and led tracker deployments requiring precise structural alignment. He is well-versed in QA/QC enforcement, risk mitigation, and issue resolution across civil, mechanical, and electrical workstreams. His background also includes transformer and switchgear inspections, CoC management, and high-volume construction team leadership. Technically grounded and commercially aware, he adds value as a disciplined OE-aligned site lead who understands both contractor delivery dynamics and client-side assurance needs.
