The Forge

1178 kVA Connected Electrical Load
780 kW Diversified System Load
61% Diversity Optimised Load Factor
400 V System Three-Phase Distribution

Electrical Services Design.

The Forge is a commercial development in Woking, Surrey, involving the major refurbishment of an existing building to deliver a flexible, multi-tenant-ready environment. The project required a robust and coordinated electrical infrastructure to support specialist systems, ensure compliance, and enable efficient power distribution across the building.

Salvis provided full electrical services design, including electrical distribution, general and emergency lighting, coordination of specialist systems, and 3D Revit modelling to support design integration and delivery.

The Challenge:

→
A large connected load (1178 kVA) required careful system sizing and load management.
→
A multi-tenant distribution strategy needed to align with a BNO-fed network.
→
The original rising busbar approach was not viable, requiring a redesign of the distribution strategy.
→
Coordination was required across lighting design, security systems, and mechanical power supplies.
→
Electrical containment routes had to be fully integrated with the architectural layout and other building services.

The Solution:

→
Designed a three-phase 400 V electrical distribution system to serve the entire building.
→
Applied ~61% diversity to reduce demand and optimise system sizing.
→
Implemented a submain distribution with Ryefield panels to suit the BNO network.
→
Developed coordinated layouts for containment, power distribution, and lighting systems.
→
Delivered general and emergency lighting design in line with project requirements.
→
Integrated specialist systems and controls into the overall electrical infrastructure.
→
Utilised 3D Revit modelling to coordinate services and minimise clashes.
→
Produced clear, structured design drawings and documentation for client approval.

Frequently Asked Questions

  • Electrical load diversity accounts for the fact that not all systems operate at full capacity at the same time. By applying diversity, engineers can reduce overall system demand, optimise equipment sizing, and avoid overspecifying infrastructure, resulting in a more efficient and cost-effective electrical design. 

  • A Building Network Operator (BNO) network distributes power to multiple tenants within a development. It requires specific infrastructure, such as submain distribution and Ryefield panels, to ensure each tenant has a safe, compliant, and independently metered power supply, influencing how the overall distribution system is designed. 

  • 3D Revit modelling enables designers to coordinate electrical systems with architectural and mechanical services in a shared environment. This helps identify clashes early, improves spatial planning for containment routes, and reduces site issues, leading to smoother installation and better project outcomes.
