Electrical Area Classification for a Prominent Energy Company

Industry: Oil & Gas / Gas Processing Infrastructur
Location:  British Columbia, Canada 
Scope : Hazardous area classification, electrical engineering review, CAD updates, authentication, and stamped final drawings
Software: CAD drafting workflows aligned with client’s drafting standards

The Challenge

Turning incomplete classification information into a practical foundation for safe equipment decisions 

The client needed updated electrical area zone classifications for their facility to support safe, standards-aligned decision-making. Without clearly defined hazardous area boundaries, specifying and installing the right field equipment becomes more complex – especially when equipment selection must align with the operating environment. 

The project called for more than drawing edits. It required disciplined engineering review, accurate drafting updates, and authenticated final documentation that the client could rely on for the next phase of execution. 

  • Hazardous area classification drawings needed to be reviewed, updated, and finalized 
  • The scope required engineering authentication and compliant documentation, not just redlines 
  • The final output needed to support downstream equipment procurement and installation decisions 
  • Clear, client-ready drawings were essential for confident execution at the facility 

The Objective

Deliver clear electrical area zone classifications that support safer procurement and installation 

The goal was to produce accurate, authenticated hazardous area classification drawings for the facility so the client could move forward with confidence in equipment planning. By classifying the electrical area zones, Prozus provided the technical basis the client needed to acquire and install radar instruments appropriately for the site conditions. 

  • Review existing hazardous area classification information and update the drawing set 
  • Apply electrical engineering judgment to finalize zone classifications 
  • Provide updated CAD documentation aligned with client standards 
  • Deliver stamped final drawings that could be used to support equipment decisions and field implementation 

Why Prozus

Engineering rigor backed by practical drafting execution 

The client engaged Prozus because the work demanded both technical accountability and efficient delivery. Our team brought together electrical engineering review, drafting updates, and project coordination in one streamlined workflow – helping the client move from uncertainty to actionable documentation without unnecessary delay. 

Rather than treating hazardous area classification as a purely administrative task, Prozus approached it as an operational enabler: documentation that would directly influence what equipment could be selected and where it could be safely installed.

Our Approach

Phase 1: Review, markups, and technical assessment 

Prozus began with a focused assessment of the hazardous area classification scope for the Altares facility. Using the client-provided information, our team reviewed the existing drawings, identified required updates, and established the engineering path to finalize the classification package. 

  • Reviewed the hazardous area classification drawing scope for the facility 
  • Assessed client-provided drawings, photographs, and supporting details 
  • Prepared redlines and markups to reflect required classification updates 
  • Applied a desktop-based engineering study to support classification decisions 

 

 Phase 2: CAD updates, authentication, and final issue 

With the technical review complete, Prozus advanced the work into updated deliverables. The drawing set was refined, authenticated, and prepared as a final package aligned with applicable requirements and the client’s drafting standards. 

  • Completed drafting updates to the hazardous area classification drawings 
  • Performed engineering review and authentication of the revised documents 
  • Prepared final stamped drawings for client use and approval 
  • Maintained communication on progress, changes, and schedule impacts throughout execution 

The Results

Stamped classifications that enabled radar procurement and installation 

Prozus delivered the updated and stamped hazardous area classification drawings the client needed to move the project forward. The final documentation gave the client a dependable electrical area zoning basis for selecting and installing radar equipment at the facility. 

By clarifying the electrical zones and issuing authenticated drawings, Prozus helped reduce uncertainty in the decision-making process and supported safer, more informed equipment deployment. 

  • Electrical area zones classified for the facility 
  • Updated CAD drawings and stamped final documents delivered 
  • Hazardous zone information provided to support radar acquisition decisions 
  • Technical clarity improved for equipment installation planning and execution 

Proven Value, Scaled Forward

Specialized engineering support that unlocks downstream action 

Projects like this show how targeted electrical engineering work can create outsized operational value. When hazardous area classifications are accurate and clearly documented, clients can move faster on instrumentation, procurement, and field planning. That makes area classification more than a compliance task – it becomes a critical enabler of execution.

The Prozus Difference: Why it Matters

Documentation that does more than satisfy requirements 

In industrial facilities, good engineering documentation is not just about completeness – it is about usability. Prozus helps clients turn technical requirements into practical deliverables that guide real decisions in the field. For this client, that meant electrical area classifications that supported the safe selection and installation of radar equipment and moved the project ahead with confidence.
