Steel Detailing Services in South Sudan: AutoCAD & Tekla
Authored by the Zenith Steel detailing team | Last reviewed: 2026-05-19
Our engineers have modelled, fabricated and shipped structural steel into South Sudan for over a decade: warehouses in Juba, school and clinic frames across Greater Equatoria, and oil-field service buildings on the Unity and Upper Nile blocks. The notes below come from our project files.
Steel detailing services in South Sudan have evolved from a technical drafting requirement into a critical project success factor. Accurate detailing ensures that every structural steel component is designed, fabricated, transported, and assembled exactly as intended before construction begins.
At Zenith Steel, we have supported projects across South Sudan through advanced steel detailing, fabrication, and logistics planning. By combining Tekla Structures, AutoCAD, and rigorous quality-control processes, we help contractors, developers, NGOs, and industrial operators reduce risk while improving construction efficiency.
Importance of Steel Detailing in South Sudan Projects
Many construction challenges in South Sudan originate long before materials reach the project site. Two constraints push the workflow toward zero on-site rework. First, the Mombasa-to-Juba haul runs the full Northern Corridor, typically 10 to 14 days through Malaba, Kampala and Nimule. A single missing gusset can pause a build for three weeks. Second, qualified welders, replacement plate stock and calibrated NDT kit are scarce outside Juba, so any joint that cannot be field-bolted with a torque wrench is a programme risk.
A missing connection plate, incorrectly sized beam, or inaccurate bolt schedule may appear minor during design but can halt construction once materials arrive hundreds of kilometres from fabrication facilities.

Unlike mature construction markets where replacement materials and specialized labour are readily available, projects in South Sudan often operate under tighter logistical constraints. Delays caused by re-fabrication, material shortages, or site modifications can significantly impact project timelines.
Professional steel detailing addresses these risks by ensuring:
- Accurate structural modelling before fabrication
- Complete coordination between architectural, structural, and MEP systems
- Precise fabrication drawings
- Efficient material procurement – Material certified through South Sudan National Bureau of Standards (SSNBS)
- Faster erection on site
- Reduced rework and construction waste
The result is a smoother transition from design to fabrication and ultimately to project completion.
How Zenith Steel Uses Tekla and AutoCAD for South Sudan Projects
At Zenith Steel, every steel detailing project follows a structured digital workflow designed using Tekla and AutoCAD to eliminate errors before fabrication begins.
1. Advanced 3D Modelling with Tekla Structures
The process begins with the development of a comprehensive 3D structural model in Tekla Structures.
Every component is digitally represented, including:
- Columns
- Beams
- Bracing systems
- Base plates
- Connection plates
- Stiffeners
- Bolts and fasteners
The model provides a complete visual representation of the structure before manufacturing begins, allowing engineers to identify and resolve potential conflicts early in the project lifecycle.
2. Clash Detection and Design Coordination
One of the most valuable advantages of Tekla Structures is clash detection. Before fabrication drawings are issued, the steel model is coordinated with:
- Architectural designs
- Mechanical systems
- Electrical installations
- Plumbing layouts
This process helps eliminate conflicts that would otherwise require costly modifications during construction.
AutoCAD for Civil and Foundation Coordination
While Tekla manages the structural model, AutoCAD supports detailed coordination with civil and foundation works.
AutoCAD drawings are used for:
- Foundation setting-out plans
- Anchor bolt layouts
- Reinforcement coordination
- Embedment plate positioning
- Site installation references
This combination ensures seamless communication between design teams, fabricators, and construction crews. Key deliverables included in our steel detailing services in South Sudan projects include:
- Detailed Tekla models – Fully coordinated 3D models with all structural elements and connections accurately represented.
- Fabrication drawings – Shop drawings showing dimensions, welds, materials, and manufacturing requirements.
- Assembly and erection drawings – Installation drawings organized according to erection sequence to simplify construction activities on site.
- CNC manufacturing files – NC files generated directly from the model to support precision cutting, drilling, and fabrication.
- Bill of Materials (BOM) – Comprehensive material schedules covering Structural members, Plates, Bolts, Fasteners, and accessories.
- BIM coordination files – IFC exports for integration with broader project BIM environments.
Every South Sudan project receives a complete detailing package designed to support fabrication, transportation, and site installation.
Why Bolt-First Connection Design Works Best in South Sudan
One of the most important lessons learned from delivering projects across South Sudan is that simplicity improves project performance.
Field welding can introduce several risks:
- Limited access to specialized welders
- Power supply challenges
- Variable quality control
- Increased installation time
For this reason, Zenith Steel prioritizes bolted connection strategies wherever structural requirements allow.

End-plate beam-to-column joints are shop-welded and shipped as single members. Splices, brace nodes and purlin cleats are bolt-only. Moment connections, where unavoidable, use bolted extended end-plates with pre-tensioned high-strength bolts to ISO 4017 / EN 14399. The result is a structure a Juba site team can erect with a torque wrench, a man-lift and a competent foreman, with no field welding generator on the truck list.We apply the same bolt-first discipline across our wider structural steelworks programme for commercial, residential and industrial projects.
Corrosion is the other constraint. South Sudan swings from a six-month rainy season (May to October on the Bahr el Ghazal and Upper Nile floodplains) to a long dry season with daytime temperatures over 40 degrees Celsius. Every member ships hot-dip galvanised to ISO 1461 by default, with a zinc-rich epoxy topcoat for prolonged ground-contact exposure such as fuel-bund frames and pipe-rack baseplates on oil-field sites.
This approach offers several advantages:
- Faster installation – Bolted assemblies can be erected quickly using standard tools and trained site personnel.
- Reduced site risk – Fewer welding operations reduce safety hazards and quality-control challenges.
- Improved construction predictability – Pre-engineered bolted connections ensure that components fit together as intended.
- Lower project costs – Reduced labour requirements and shorter installation periods contribute to overall project savings.
Oil-Field Detailing: Bentiu, Paloich and the Upper Nile Blocks
The oil-producing belt, principally Unity State around Bentiu and Upper Nile State around Paloich, accounts for the bulk of national crude. Detailing for this belt differs from a Juba warehouse in one respect: hazardous-area compliance. Process-side service buildings are classified as IECEx hazardous areas, typically Zone 1 or Zone 2 depending on proximity to well-head, separator or storage tank.
Our Tekla model carries those implications through to fabrication. Earthing bosses for lightning protection are detailed and shop-welded. Cable-tray support cleats are pre-drilled so electricians can mount explosion-proof junction boxes without drilling galvanised members on site (which would compromise the coating). Stair stringers and handrails suit anti-static walking surfaces, and every primary member carries a piece-mark the operator’s HSE auditor can read against the as-built drawing.
For donor-funded and civilian work, the discipline is the same. School and clinic frames across Greater Equatoria, market warehouses in Juba and Wau, and the prefabricated bays we ship regionally all run off the same Tekla-first sequence. These builds feed our cluster of posts on water tanks and steel sheds for South Sudan infrastructure, steel church buildings for South Sudan’s growing communities, and prefabricated steel structures for South Sudan.
Logistics Planning: Engineering Beyond the Workshop
Successful steel projects in South Sudan depend on more than accurate detailing. Transportation planning is equally important.
Materials typically travel through the Northern Corridor from Nairobi through Uganda and into South Sudan via Nimule before reaching their final destinations.
To optimize transport efficiency, Zenith Steel incorporates logistics considerations during the detailing phase, including:
- Transport-friendly member lengths; 14 to 18 metre
- Optimized load configurations
- Site assembly strategies
- Phased delivery schedules
- Documentation for customs clearance such as mill certificates, fabrication QA, weld procedure log, dimensional report, HDG film-thickness readings and the piece-mark register
This integrated approach helps minimize transportation costs while reducing project delays.
