Century Containers deliver on PUMA Project PPE Stores

The PUMA Project required the design, fabrication, and supply of containerised PPE Stores and Rigging Stores to support ongoing site operations within a live industrial and construction environment. The project was commissioned by S&J Synergy, operating within a multi-tier contractor structure involving Bilfinger Construction and Mitsubishi UK. The requirement was for heavy-duty container storage units capable of supporting daily operational use on an active site, while meeting the technical, safety, and quality expectations associated with tier-one infrastructure projects. The solution needed to deliver: Robust shipping container conversions for PPE and rigging storage Practical internal layouts aligned with real site usage Compliance with industrial health and safety requirements Rapid deployment with minimal site integration works Our scope included full container modification, internal fit-out, electrical installation, testing, and coordination through to delivery.

Century Containers deliver on PUMA Project PPE Stores

Challenge:

Technical & Specification Challenges

  • Translating detailed PPE and rigging storage requirements into compact container-based storage units without compromising usability or safety.
  • Ensuring the units were suitable for heavy-duty industrial use, including storage of bulky and high-load rigging equipment.
  • Integrating safe and compliant electrical systems within the shipping containers.

Programme & Delivery Constraints

  • Fixed delivery dates aligned with the wider PUMA Project construction programme.
  • Requirement to fabricate multiple bespoke container units concurrently while maintaining consistent build quality.
  • Navigating layered approval processes across S&J Synergy, Bilfinger Construction, and Mitsubishi UK.

Operational & Site Considerations

  • Units needed to arrive fully operational and ready for immediate use on site.
  • Designs had to reflect real operational behaviour, including frequent access, varied equipment sizes, and durability in harsh site conditions.

Solution:

Design & Engineering Approach

  • Developed bespoke shipping container conversions specifically engineered for PPE and rigging storage applications.
  • Specified and utilised 30ft High Cube containers to create bespoke dimensions beyond standard container formats, allowing:
    • Increased internal volume for bulky PPE and rigging equipment
    • Improved headroom and vertical storage capacity
    • More efficient internal zoning and circulation
  • Optimised internal layouts to:
    • Maximise usable floor and wall space within standard container dimensions
    • The use of quality materials
    • Improve access, circulation, and safe equipment handling
    • Clearly organise PPE and rigging equipment for efficient daily use
  • Integrated CorkSol thermal and anti-condensation coating within the containers to:
    • Reduce internal condensation common in steel containers
    • Improve thermal comfort for operatives accessing the units
    • Protect stored PPE and rigging equipment from moisture-related degradation
    Designed and manufactured bespoke rigging hook systems, tailored to the client’s specific rigging equipment sizes and load requirements, ensuring:
    • Secure and clearly organised storage
    • Improved manual handling and access
    • Long-term durability under repetitive heavy use
  • Selected materials and finishes suited to long-term industrial and construction environments.

  • Associated Side Project: 10ft Tunnel Container Clocking-In Station Alongside the main scope of works, we delivered a bespoke 10ft tunnel container adapted for use as a site clocking-in / access control station.
    • The tunnel configuration allowed through-access, supporting controlled personnel consideration without creating bottlenecks at site entry points.
    • Internal modifications were designed to accommodate:
      • Clocking-in hardware and access control systems
      • Clear pedestrian flow and visibility
      • Robust finishes suitable for high-frequency daily use
    • The compact 10ft footprint enabled flexible placement close to site entrances while maintaining durability and security.
    This side project demonstrated our ability to rapidly adapt container formats for ancillary site infrastructure, complementing the primary PPE and rigging storage assets.

Fabrication & Quality Control

  • All container modifications and fabrication works were completed in-house using a controlled and repeatable production process.
  • Heavy-duty fixings, shelving, and structural elements were installed to safely support rigging loads.
  • Electrical installations were completed, inspected, and tested prior to dispatch.
  • Each container unit underwent final quality checks to ensure compliance with approved specifications.

Stakeholder Coordination

  • Maintained structured communication with S&J Synergy while ensuring alignment with Bilfinger Construction and Mitsubishi UK requirements.
  • Responded efficiently to technical queries and specification clarifications without impacting programme timelines.
  • Managed approvals in parallel with fabrication to maintain delivery certainty.

Outcome:

Outcome

  • Successful delivery of fully compliant containerised PPE Stores and Rigging Stores ready for immediate deployment on site.
  • Units met all functional, durability, and safety expectations set by the client and principal contractors.
  • Fabrication and delivery were completed within the agreed construction programme, supporting uninterrupted site operations.
  • Positive feedback received regarding:
    • Build quality of the container conversions
    • Practicality of the internal storage layouts
    • Overall robustness and suitability for industrial use

Health & Safety Considerations

  • Container designs prioritised safe access, clear internal organisation, and secure storage of PPE and rigging equipment.
  • Electrical systems were installed and tested in accordance with applicable industrial standards.
  • Fabrication processes followed internal health and safety controls to minimise risk during container modification works.
  • Units were delivered as self-contained assets, reducing installation and commissioning risk on site.

Sustainability & Asset Reuse

  • The project utilised shipping containers as the primary structural base, extending the lifecycle of existing assets.
  • Container-based storage solutions reduced the requirement for permanent site buildings.
  • Units are fully relocatable and reusable, supporting future redeployment across multiple sites and reducing environmental impact.

Key Learnings & Continuous Improvement

  • Early engagement with all stakeholders was critical in managing specification complexity on a multi-contractor project.
  • Parallel fabrication and approval workflows improved programme certainty.
  • Lessons learned from this project have been incorporated into future containerised PPE and storage unit designs, improving efficiency and usability.
