Electrical Infrastructure for a Secure Correctional Environment. Winchester CASU is a correctional facility project requiring highly coordinated electrical infrastructure, fabrication documentation, and multidisciplinary BIM coordination.
Karno Energy was responsible for electrical system modelling, lighting and power layouts, cable tray and conduit coordination, fabrication drawings, and technical support throughout project delivery.
[ Challenges ]
Coordinating Electrical Systems Within a Secure Facility
Electrical systems had to be integrated within a highly controlled environment while maintaining safety, accessibility, and installation efficiency.
- Lighting systems
- Power systems
- Cable infrastructure
- Secure facility requirements
Without proper coordination, this would normally result in:
- System clashes
- Installation delays
- Access conflicts
- Construction rework
Routing Cable Trays & Conduits Through Limited Space
Electrical containment systems had to be coordinated alongside other building services while maintaining installation accessibility and construction feasibility.
- Cable tray routing
- Cable tray routing
- Service zone management
- Clash prevention
This created risks such as:
- Space conflicts
- Installation issues
- Coordination delays
- Reduced installation efficiency
Delivering Accurate Fabrication Documentation
The installation team required highly detailed fabrication drawings to support accurate construction and reduce uncertainty during installation.
- Electrical fabrication drawings
- Lighting layouts
- Containment documentation
- Installation support
Without sufficient detailing, this would normally result in:
- Installation errors
- Site modifications
- Construction delays
- Additional project costs
[ Solutions ]
Electrical Infrastructure Development
Electrical systems were developed to support lighting, power distribution, and containment requirements while maintaining compliance with project standards.
- Core engineering activities included:
Containment Coordination & Routing
Cable trays and conduits were coordinated with architectural, structural, and MEP systems to ensure efficient installation and clash-free routing.
- Coordination activities included:
This ensured smooth installation and reduced construction risks.
MEP Coordination & System Updates
Alongside electrical systems, heating and domestic cold water systems were updated and coordinated to maintain consistency across the project.
- Coordination activities included:
Fabrication Documentation & Delivery
Detailed fabrication drawings were prepared to support construction teams and improve installation efficiency throughout the project.
- Final deliverables included:
The final BIM package improved installation efficiency and reduced uncertainty during construction.
[ Scope of Work ]
The initial project scope included
Working from project information provided by the client, our team developed coordinated electrical systems, fabrication drawings, and multidisciplinary BIM deliverables suitable for construction.

[ Delivery Process ]
Electrical System Planning & Coordination Strategy
The project began with a review of electrical design requirements, lighting layouts, and containment systems to establish a coordinated BIM workflow.
- So we started with the key project requirements:
-
Review electrical system information
-
Define fixture locations
-
Establish coordination workflows
- Following approval, project standards were established:
-
Electrical modelling standards
-
Containment routing rules
-
Documentation requirements
BIM Modelling & MEP Coordination
Electrical systems, cable trays, conduits, heating, and domestic cold water systems were coordinated within the BIM environment to ensure installation feasibility.
- Key efficiencies included:
-
Electrical system modelling
-
Cable tray & conduit routing
-
Navisworks clash detection
This ensured that all systems remained coordinated and ready for fabrication and installation.
Fabrication Documentation & Project Delivery
Detailed fabrication documentation and coordinated BIM deliverables were prepared to support installation teams and project delivery.
-
Electrical fabrication drawings
-
Coordinated BIM models
-
Construction-ready deliverables
The final BIM package provided clear installation guidance and improved overall construction efficiency.
[ Results ]
The project delivered a coordinated electrical BIM environment, fabrication documentation, and multidisciplinary engineering models that improved installation efficiency and construction readiness.
