Engineered Access at 75 Metres: MOSCO Supports Critical Works on ArcelorMittal BOF Stack
At MOSCO Specialised Contractors, we understand that complex industrial work begins long before the first person reaches the workface. It begins with planning, engineering, collaboration, and a clear commitment to safety.
MOSCO is currently erecting an engineered, purpose-designed scaffold to provide safe access and structural support for works on the ArcelorMittal Basic Oxygen Furnace three-legged stack.
Standing at an impressive height of 75 metres, this scaffold is far more than a temporary access structure. It is a carefully designed support system, developed to meet the demanding requirements of a complex industrial environment where safety, stability, load capacity, and operational coordination are critical.
The scaffold has been engineered and constructed in accordance with the requirements of SANS 10085, ensuring that every stage of the design and erection process is guided by recognised safety and engineering standards. From the ground up, the structure reflects a disciplined approach to scaffold design, load planning, access control, inspection readiness, and safe execution at height.
This project has required an integrated service approach, with MOSCO working in close collaboration with all relevant stakeholders to ensure that the scaffold meets the full operational, engineering, maintenance, and future demolition requirements of the project.
Designed to safely support an approximate load of more than 35 tonnes at height, the scaffold will carry Level 6, the burner assemblies, and the associated working platform. It will also provide secure access for personnel involved in critical inspection, maintenance, and future demolition activities on the BOF stack.
In a project of this nature, access is not simply about getting people to a certain elevation. It is about creating a safe, controlled, engineered environment that allows every trade and every activity to be performed with confidence.
On a structure of this scale, strong scaffold design is not only about height or load capacity. It is about protecting people, supporting the work, and giving every stakeholder confidence that the job can be done safely and correctly.
That principle sits at the centre of MOSCO’s approach.
The scaffold will provide secure working platforms, controlled access routes, and the required structural support throughout the different phases of the project. Each level, platform, tie, brace, and access point forms part of a broader engineered solution designed to support safe productivity in a high-risk industrial environment.
The image captures the scale of the challenge: a 75-metre structure rising around the BOF stack, with multiple elevations, complex geometry, and demanding access requirements. It also captures something equally important — the people behind the work. Every scaffold of this nature is the result of teamwork between engineers, planners, supervisors, safety teams, scaffolders, client representatives, and operational stakeholders.
Projects like this demonstrate the strength of specialist access contracting. They require technical knowledge, disciplined execution, detailed planning, and the ability to adapt to the realities of a live industrial site. They also require leadership — not only in the boardroom or design office, but on the ground, every day, where decisions directly affect the safety and success of the work.
At MOSCO Specialised Contractors, we remain committed to delivering innovative access and support solutions for complex industrial projects. Our focus is to combine technical expertise, engineering excellence, practical site experience, and an unwavering commitment to safety.
This 75-metre BOF stack scaffold is another example of what can be achieved when engineering, teamwork, and leadership come together with a shared purpose: to provide safe access, reliable support, and confidence at every level.
