One investment, multiple employers

In large-scale industrial projects, multiple companies often find themselves working on the same electrical infrastructure at the same time. One company installs the system, another tests it, and a third commissions individual components. Added to this are temporary power supplies, coordinated outages, and early power restorations. Technically, everything is interconnected; however, from an organizational standpoint, each employer remains responsible for its own employees and activities. Centralized project coordination does not eliminate this responsibility.

Interfaces must be capable of making decisions

The situation becomes critical when a decision affects multiple parties. Who oversees a shutdown? Who verifies that the system is de-energized? Who is authorized to restore power to a system? Who notifies the other employers? A responsibility and interface matrix should specifically assign these functions. It is effective when it not only lists names but also describes system boundaries, decision-making authority, information flows, and escalation procedures.

Work Permits and Lockout/Tagout Must Be Aligned

An existing permit system and the use of lockout-tagout procedures provide a good foundation, but they are not an end in themselves. They become effective only when monitoring, verification, restoration of operational status, and the protection of all affected parties have been clearly defined. Joint isolations require particularly thorough handoffs. No one should have to assume that a lock or a form automatically clarifies the organizational interface.

Coordination Does Not Replace an Employer’s Obligations

The Industrial Safety Regulation and occupational safety and health laws impose obligations on the respective employer. Joint project rules can structure collaboration, but they do not generally shift these obligations to a coordinator. Especially when external contractors are involved, it must therefore remain clear which organization qualifies, trains, and assigns its employees, and which joint point of contact applies to the specific facility.

When an Interim CRES Can Help

Within a clearly defined business unit, an external CRES can serve as the technical authority for a limited period of time. In doing so, it does not assume responsibility for all project parties. Rather, it ensures that its own electrical engineering organization functions reliably and that the interfaces with project coordination are technically sound. A sense of proportion is also important when it comes to documentation: qualification and approval information required for the entire project must be available; however, complete personnel files do not generally belong in a shared project repository.

Checkpoints

  • Define System Boundaries
  • Unambiguously Assign Approvals
  • Regulate shared insulation
  • Define “escalation”
  • Keep Records in a Targeted Manner

Conclusion

Multiple companies involved in a single facility do not need vague overall responsibility, but rather clearly defined areas of responsibility and technically functional interfaces. An interim CRES can stabilize its own organization if its authority and scope are clearly defined.
