What Aurex Constructors does

Aurex Constructors is a privately held South African industrial construction, turnaround, and maintenance contractor delivering integrated end-to-end solutions to blue-chip customers across all energy sectors. The company operates through four core service lines — Construction (SMEIPP scope: structural, mechanical, electrical, instrumentation, piping and platework), Turnarounds and Shutdown Services, Maintenance, and Fabrication — applied across four primary verticals: oil, gas and chemicals; renewable energy; thermal power; and mining and metallurgy. Its customer roster includes Sasol, Shell, Natref, Astron Energy, ENGIE, Scatec, Pele Green Energy, Mulilo, Mitsubishi Hitachi Power Systems and General Electric, reflecting a 40-year operating lineage that traces back to a 1981 founding as Kentz Engineers and Constructors and a December 2020 management buy-out from SNC-Lavalin that re-established the business as a 100% South African-owned platform with 51% black ownership.

The company's technology stack centres on digital project execution rather than AI: a proprietary People App that maintains a credentialed contractor database and accelerates mobilisation, cloud-based time and attendance systems, barcoding/scanning for stores control, custom reporting dashboards, and a Microsoft 365 E5 security environment supported by Netsurit. Over the 24 months preceding 2025, Aurex stood up an in-house engineering department, enabling it to self-perform utility-scale solar PV EPC rather than rely on third-party engineering. Fabrication capacity is anchored at the Chamdor/Krugersdorp facility for piping, pressure vessels and structural steel, and workforce training is delivered through the Bokhabane Assessment Centre and the Boitjhorisong Welding Training Centre operated in partnership with Sasol and Afrox.

Aurex earns revenue almost exclusively through long-cycle, project-based enterprise contracts negotiated per engagement via competitive tendering (notably REIPPPP bid windows) or direct award with established customers. Revenue streams span one-time EPC and sub-EPC contracts (renewable energy solar PV, processing plant construction, mining SMEIPP), professional services for turnaround and maintenance (3,000–5,500-person mobilisations on petrochemical shutdowns, recurring terminal and refinery maintenance), and fabrication. Contract values are highly lumpy and range from sub-R5 million shutdowns to multi-hundred-million-rand multi-year framework agreements, with the company's go-to-motion being direct enterprise field sales targeting energy sector accounts across Southern Africa with selective expansion into the Middle East.

Core offering

Aurex Constructors delivers end-to-end construction, turnaround/shutdown, and maintenance services across energy sectors including oil & gas, renewables, thermal power, and mining. Core offerings include fully integrated EPC construction services (SMEIPP scope), multi-discipline plant turnarounds, scheduled and breakdown maintenance, and piping/structural/trailer fabrication from its Krugersdorp facility. The company serves as a self-performing contractor with in-house engineering capability for utility-scale solar PV projects, mobilising workforces from 56 to over 5,500 personnel per project.

Product overview

Aurex Constructors is a South African industrial construction, turnaround, and maintenance company offering end-to-end solutions across all energy sectors. The company operates as a unified service provider rather than a platform product, delivering four core services: Construction (SMEIPP services), Turnarounds/Shutdown Services, Maintenance, and Fabrication. These services are delivered across four energy sectors: Oil, Gas & Chemicals; Renewable Energy; Thermal Energy; and Mining & Metallurgy. The company has evolved from a traditional construction contractor to offering integrated EPC solutions, particularly in renewable energy where it now self-performs engineering, procurement, and construction for utility-scale solar PV projects. Notable projects include the Kenhardt Solar Power Stations (540 MW solar + 150 MW battery storage), Grootspruit and Graspan plants (75 MW each), and major petrochemical turnaround work for Sasol and Natref. The company also developed proprietary digital tools including the People App for workforce management.
