At 3SC Group Scaffolding Ltd, we were appointed to deliver a specialist access solution inside a ship lift shaft at Portland Port. The project involved providing safe, stable vertical access so maintenance engineers could carry out cable repair and replacement within a confined industrial environment.
From the outset, this was not a standard scaffold build. The restricted shaft space, combined with the operational nature of the maritime facility, meant every stage required careful planning and close coordination with the client’s schedule.
Our team designed and installed a modular birdcage scaffold system that could adapt quickly if site conditions changed — which proved critical as the project progressed.
Scope of Works
The primary objective was to create a safe internal working platform within the lift shaft while maintaining full compliance with current health and safety standards.
The works included:
- Installation of an initial single-lift birdcage scaffold to provide immediate safe access.
- Expansion of the structure to a three-lift configuration when additional defects were identified.
- Installation of edge protection throughout the working platforms.
- Use of non-slip scaffold decking to improve footing in the confined shaft.
- Secure bracing to maintain full structural stability within the vertical space.
- Careful sequencing of assembly due to tight access restrictions.
Because the work took place inside active maritime infrastructure, our approach focused heavily on precision, safety, and flexibility.
Timeline & Team
This was a fast-paced project delivered efficiently by our experienced team.
- Duration: 2 days.
- Team size: 3–4 fully qualified scaffolders.
- Scheduling: Coordinated around live shipyard operations to minimise disruption.
Our ability to mobilise quickly and work within tight operational windows ensured the client’s maintenance programme stayed on track.
Key Challenges
Working inside a lift shaft at Portland Port presented several technical and logistical challenges.
Confined vertical shaft
The limited working area meant traditional scaffold methods would have been impractical. We addressed this by designing a compact modular birdcage system that could be assembled safely within the restricted footprint.
Unexpected broken lift cables
During the project, additional cable damage was identified. Because we had implemented a modular design from the start, we were able to extend the scaffold rapidly from a single lift to three lifts without delay.
Limited space for materials and movement
The tight environment required careful sequencing of components and controlled material handling. Our team followed a precise build sequence to maintain safety at every stage.
Tight access and vertical assembly
Access into the shaft was restricted, so every lift had to be planned in advance. Detailed pre-planning allowed us to maintain steady progress while ensuring full compliance with SG4:15 safe working practices.
Our Solution
We delivered a purpose-built modular birdcage scaffold tailored specifically to the lift shaft environment.
Key elements of our approach included:
- Designing the scaffold to allow rapid vertical expansion if required.
- Using non-slip decking to improve operative safety in the shaft.
- Installing full edge protection on all working lifts.
- Implementing robust bracing to maintain rigidity within the confined structure.
- Sequencing the build carefully to suit the restricted access point.
- Working flexibly around live port operations.
Because of this structured approach, we were able to respond immediately when the scope changed, without causing delays to the client’s programme.
Health & Safety Focus
Safety remained the top priority throughout the project.
Our team ensured:
- Full compliance with TG20:13 guidance.
- Safe working practices in line with SG4:15.
- Continuous stability checks during vertical build.
- Secure access and egress within the shaft.
- Clean and controlled working environment.
- Zero safety incidents from start to finish.
Working in maritime infrastructure environments demands strict attention to detail, and our experienced scaffolders delivered exactly that.
The Outcome
The completed scaffold structure provided the client with safe, reliable access to carry out the required cable repairs inside the ship lift shaft.
Project results included:
- Safe vertical working access achieved.
- Rapid adaptation when additional cable faults were discovered.
- Minimal disruption to ongoing shipyard operations.
- Project delivered within the planned timeframe.
- Zero accidents or safety issues reported.
The modular approach proved especially valuable, allowing the maintenance team to proceed without waiting for redesign or major alterations.
Client Feedback
“The scaffold team adapted brilliantly to unexpected lift cable issues. Their flexible solution kept the project on schedule and ensured safe working conditions throughout.”
Why This Project Matters
This project highlights our ability at 3SC Group Scaffolding Ltd to deliver specialist scaffolding solutions in complex industrial and maritime environments.
Not every scaffold is straightforward. When access is tight, conditions change, and programmes are under pressure, experience and adaptability make the difference.
Whether it is a confined shaft, port infrastructure, or complex industrial setting, we provide safe, compliant access solutions that keep projects moving.
