At 3SC Group Scaffolding Ltd, we were commissioned to provide a safe and practical access solution beneath the corded gantry of a port linkspan at Portland Port. The purpose of the scaffold was to enable the Port Authority maintenance team to install and maintain electrical cable racking in a confined, operational maritime environment.
This was a specialist project that required careful planning from the outset. The working area sat directly beneath live port infrastructure, so the scaffold needed to provide full safe access while allowing normal port activity to continue without interruption.
We delivered a bespoke low-clearance birdcage scaffold designed specifically to suit the restricted headroom and high-traffic surroundings.
Client Profile
The client for this project was the Port Authority Maintenance Team, responsible for ongoing infrastructure upkeep within the port.
Their key requirements included:
- Safe and secure access beneath a live gantry structure.
- Minimal disruption to vessel movements and port traffic.
- Full compliance with health and safety regulations in a busy industrial environment.
From our initial consultation, it was clear that the solution needed to be compact, robust, and carefully sequenced to fit around operational constraints.
Scope of Work
We designed and erected a custom birdcage scaffold directly beneath the corded gantry to provide stable working access for electrical installation works.
Scaffolding solution
- Bespoke birdcage scaffold positioned beneath the linkspan gantry.
- Approximate footprint of 3m x 3m.
- Low working height of around 1 metre to match linkspan clearance.
- Full working platform to support electrical maintenance tasks.
Specialist elements
- Low-clearance birdcage design tailored to the restricted overhead space.
- Non-slip scaffold decking installed to improve operative safety.
- Secure baseplates are used to ensure full stability on the working surface.
- Sectional assembly method to reduce obstruction during installation.
Because the work took place within live port infrastructure, port approval and a full risk assessment were required prior to commencement. Our team handled all necessary planning documentation to ensure a smooth sign-off.
Timeline & Team
This project was delivered efficiently within a tightly controlled operational window.
- Project duration: 1 day.
- Team size: 2 scaffolders and 2 labourers.
- Scheduling: Carefully coordinated around vessel movements and port activity.
By planning the sequence in advance, we completed the installation quickly while maintaining strict safety standards throughout.
Key Challenges
Working beneath a live port gantry presented several technical and logistical challenges that required a measured, experienced approach.
Limited overhead clearance
The restricted headroom beneath the corded gantry meant a standard scaffold would not have been suitable. We addressed this by designing a purpose-built low-profile birdcage system that maximised safe working space within the available clearance.
Live port environment
The scaffold was erected in an active industrial setting with ongoing vehicle and vessel traffic. Our team worked closely with port control to ensure the build was carried out safely and without interfering with operations.
Confined assembly space
Space for materials and erection was tight. We used a sectional assembly method, allowing the structure to be built progressively while keeping the surrounding area clear and controlled.
Our Solution
To meet the client’s requirements, we implemented a carefully engineered birdcage scaffold designed specifically for the linkspan environment.
Our approach included:
- Designing a compact birdcage to suit low-clearance conditions.
- Installing non-slip decking for improved footing.
- Using secure baseplates to maintain structural stability.
- Building the scaffold in controlled sections to minimise disruption.
- Coordinating closely with port management throughout the works.
- Preparing full RAMS documentation for safe working under the live gantry.
This method allowed the electrical team to begin work immediately once the scaffold was handed over.
Health & Safety
Safety was central to every stage of this project.
We ensured:
- Non-slip scaffold boards were fitted across the working platform.
- Baseplates were properly seated and checked for stability.
- Full RAMS (Risk Assessments and Method Statements) were prepared and approved.
- Work was carried out in line with TG20:13 guidance.
- SG4:15 safe working practices were followed throughout.
- Continuous communication was maintained with port control.
Our experienced team is well accustomed to working in high-risk industrial environments, and this project was delivered with zero safety incidents.
The Outcome
The completed birdcage scaffold provided the Port Authority maintenance team with safe, reliable access to the electrical cable racking beneath the linkspan gantry.
Key results included:
- Safe and efficient access for electrical installation and maintenance.
- Project completed on schedule.
- No disruption to port operations or vessel movements.
- Early completion helped avoid potential downtime costs.
- Zero accidents or safety concerns reported.
The bespoke design ensured the client could carry out essential infrastructure work without impacting the wider port environment.
Client Testimonial
“The scaffold team designed a solution that allowed our electricians to work safely under the gantry, with zero disruption to port activity. Their professionalism and attention to safety were excellent.”
