Riyadh Metro is one of the region’s most ambitious mobility programs, representing a total investment of 22 billion dollars, built to ease congestion and improve access across the capital.

The six-line, 176 km network requires power systems that run reliably in tunnels, stations, depots and control facilities.

alfanar was selected to manufacture and supply low-voltage panels, package substations and MV/LV cables, engineered for safe distribution in a multi-contract environment with strict standards and complex interfaces.

Keeping production moving amid shifting designs

As the project follows a fast-track design-and-build approach, production and drawing issuance progressed in parallel with ongoing design revisions, requiring continuous coordination to align with the latest updates.


Frequent revisions risked material waste, factory downtime, and missed FAT slots. Deliveries still had to align with site needs and meet ADA, SEC and IEC requirements, with zero tolerance for lapses during energisation and testing.

Modular manufacturing with live design control

A dedicated design interface team tracked SLD changes and pushed approved updates straight into manufacturing drawings. Modular build processes let factories adapt with minimal scrap. A clear technical clarification flow resolved ambiguities with EPCs before fabrication.

QA/QC, planning and engineering re-sequenced FAT in parallel with drawing updates, while digital document control kept current BOMs and drawings visible to every department.


Local manufacturing shortened lead times; site teams coordinated delivery, SAT and handover with training and technical support.
