🚀 Role Summary

• This is a highly specialized design execution role focused on the development of Building Information Modeling (BIM) and Extra Low Voltage (ELV) systems, specifically within the demanding context of Data Center environments.

• The core of this position revolves around the meticulous creation and management of detailed AutoCAD and potentially Revit drawings for critical ELV infrastructure.

• This role requires a strong understanding of ELV system components and their integration, ensuring accurate and compliant technical documentation for mission-critical projects.

• Collaboration with multi-disciplinary engineering teams is essential to translate design concepts into precise, high-quality construction drawings that meet stringent project and client specifications.

📝 Enhancement Note: While the title includes "Principal Designer," the core responsibilities and experience level suggest a senior-level technical drafting and design execution role rather than a strategic design leadership position. The focus is on detailed CAD/BIM work for ELV systems in data centers.

📈 Primary Responsibilities

• AutoCAD Drawing Development (CORE RESPONSIBILITY):

  • Prepare and update detailed AutoCAD drawings for various ELV systems, including CCTV (camera layouts, coverage zones), Access Control Systems (door layouts, reader locations), Fire Alarm Systems (detector placements, panel connections, loop diagrams), and Public Address/Voice Alarm (PA/VA) systems.
  • Develop comprehensive device layouts, placement drawings, and intricate cable routing and containment layouts.
  • Create clear and accurate schematic diagrams, including single-line diagrams and system-level diagrams.
  • Ensure all drawings adhere strictly to project standards, client requirements, and relevant industry codes.

• ELV System Drafting & Detailing:

  • Translate high-level design inputs and concepts into detailed, constructible drawings.
  • Prepare essential documentation such as riser diagrams, zoning layouts (defining security and access levels), and detailed equipment room layouts for ELV and control centers.
  • Maintain and enforce consistent layer standards, block libraries, legends, and drawing templates to ensure uniformity and efficiency.

• Coordination with Design Team:

  • Actively participate in design coordination meetings with multi-disciplinary teams (e.g., electrical, structural, mechanical).
  • Ensure seamless integration of ELV system designs with other project disciplines by resolving clashes and design conflicts early in the process.
  • Support design engineers by providing accurate and timely drawing deliverables, facilitating design progression.

• BIM/Revit Integration (Preferred):

  • Contribute to BIM models by developing and integrating ELV system components and layouts within a Revit environment.
  • Ensure consistency between 2D AutoCAD drawings and 3D BIM models where applicable.
  • Leverage BIM for clash detection and visualization of ELV systems within the overall data center design.

• Standards and Compliance:

  • Familiarize with and apply relevant industry standards for data centers, such as TIA-942, and fire/safety standards like NFPA, as well as local building codes (NBC).

  • Ensure all drafted designs comply with these standards and best practices for reliability and safety in mission-critical environments.
