ISG Engineering is proud to announce the successful completion of its largest project to date: the structural steel works for VSL’s new automotive manufacturing facility in the heart of Gqeberha, Eastern Cape. The project marks a significant milestone not only for ISG, which celebrates two decades of engineering excellence, but also for the region’s industrial landscape. With 660 tonnes of fabricated and erected structural steel, a footprint of 9,800 m², and more than 7,000 m² of gantry-crane-supported production space, the new facility sets a benchmark for scale, precision, and efficiency in South African steel engineering.
Delivered over 16 months from conceptual design to final handover, the project demonstrates ISG Engineering’s growing capacity to serve large-scale industrial developments and support the next wave of advanced manufacturing in the Eastern Cape.
Building the Backbone of an Automotive Future
The Eastern Cape has long been recognised as a major automotive production hub, and VSL’s investment in a new manufacturing operation further strengthens this position. For ISG Engineering, being selected as the structural steel partner for a project of such strategic significance came with both honour and responsibility.
The design brief called for a modern industrial facility capable of housing heavy-duty fabrication, assembly, and material-handling systems. The 7,000 m² gantry crane area is critical to VSL’s operational workflow, requiring exceptional design accuracy and robust steel structures engineered to withstand significant dynamic loads.
A 660-Tonne Structural Achievement
The sheer scale of the steel requirements placed this project among the most technically demanding assignments in ISG’s 20-year history. A total of 660 tonnes of structural steel was fabricated at ISG’s workshop and transported to the Port Elizabeth site for assembly.
The steel package included:
- Primary and secondary steel framing for the 9,800 m² warehouse
- Heavy-duty craneways designed for continuous operational loads
- Large-span roof trusses enabling a column-free internal environment
- Support structures for mechanical and electrical services
- Walkways, platforms, and access systems to ensure safe site navigation
Each component was fabricated to stringent quality standards, and the erection schedule required precise phasing to align with civil progress and crane installation milestones.
Design to Completion in 16 Months
One of the project’s defining achievements was the timeline. Completing a facility of this size and complexity within a 16-month window demanded exceptional project coordination, disciplined planning, and technical agility.
The process followed a tightly controlled workflow:
- Conceptual and Structural Design
ISG’s engineering team collaborated on the initial conceptualisation and modelled the structural framework using advanced 3D design software. This allowed quick resolution of geometric challenges, load-path optimisation, and early clash detection with MEP (mechanical, electrical, and plumbing) interfaces.
- Detailed Fabrication Modelling
Once the structural design was finalised, ISG transitioned into detailed workshop drawings. The use of BIM-based detailing ensured that every component, down to the smallest gusset plate, was accurately captured for fabrication.
- Precision Fabrication
At ISG’s fabrication facility, the steelwork was cut, welded, assembled, and quality-checked by a dedicated team of artisans, NDT technicians, and supervisors. Lean manufacturing techniques were used to reduce waste and improve turnaround time.
- On-Site Erection and Integration
Erection was performed in sequenced zones, enabling civil contractors and MEP teams to follow closely behind. The installation of the gantry craneways required high-capacity mobile cranes, precise alignment, and rigorous safety protocols.
- Final Inspection and Handover
Upon completion, the structure underwent a comprehensive inspection process, including load testing of critical crane beams and final quality assurance checks before being handed over to VSL.
The synchronisation of multiple disciplines, design, fabrication, logistics, and site assembly, was key to maintaining momentum throughout the project timeline.
Engineering Challenges and Technical Solutions
Large-scale industrial structures always present unique challenges, and this project was no exception. Some of the key technical hurdles included:
Long-Span Requirements
The facility required wide, column-free spaces to optimise manufacturing flow. ISG engineered custom long-span roof trusses capable of carrying substantial loads while maintaining structural stability across the nearly 10,000 m² footprint.
Gantry Crane Integration
With 7,000 m² dedicated to gantry crane operations, craneways had to be designed with exceptional stiffness and precision. Millimetre-level accuracy was required during installation to ensure smooth crane travel and consistent load distribution.
Wind and Environmental Loads
Located in a coastal region, the structure had to withstand elevated wind loads and corrosion risks. ISG applied enhanced corrosion-protection coatings and specified steel profiles suited for long-term durability.
Tight Site Logistics
Working in the centre of Port Elizabeth meant navigating limited space for laydown areas and prefabrication staging. ISG implemented a just-in-time logistics approach, ensuring steel arrived on site exactly when needed, reducing congestion and maintaining safety.
A Milestone in ISG’s 20-Year Journey
Completing this project during ISG Engineering’s 20th anniversary underscores how far the company has evolved since its early days. From small-scale steel fabrication work to large, complex industrial structures, ISG has expanded its expertise, workforce, and technical capabilities year after year.
This project represents a defining chapter in that journey:
- The largest tonnage of steel ever fabricated and erected by ISG
- The largest physical footprint completed in a single project
- The longest continuous gantry crane installation the company has delivered
- A model of engineering coordination from concept through completion
For ISG’s leadership and project teams, the VSL facility stands as a testament to the company’s commitment to quality, innovation, and the continued growth of South African engineering talent.
Strengthening Industrial Development in the Eastern Cape
Beyond the technical milestones, the project also contributes to broader regional development. VSL’s new automotive facility supports increased manufacturing capacity, job creation, and economic activity in the Eastern Cape, particularly in Port Elizabeth, which has a deep heritage in vehicle production.
ISG Engineering is proud to have played a role in a development that will continue to benefit the community for years to come.
Looking Ahead
With the successful completion of this landmark project, ISG Engineering continues to position itself as a trusted partner for large-scale industrial, commercial, and infrastructural steel projects. The expertise developed, the lessons learned, and the collaborative relationships formed through the VSL project will inform and strengthen future work across South Africa and beyond.
As ISG looks ahead to its next chapter, this achievement stands as a powerful reminder of what the company can accomplish: engineering excellence built on teamwork, precision, and a commitment to delivering structures that shape industries.
