  • Work with Prefabrication Shop Leads to optimize assembly layouts, build sequencing, and packaging for efficient delivery and installation.
  • Perform self‑checks and participate in peer reviews prior to releasing design packages for production.
  • Ensure all prefabrication designs meet company standards, NEC requirements, and field constructability expectations.
• Lighting Controls Detailing
  • Develop prefabrication build sheets, riser diagrams, and layouts for lighting control systems, including occupancy sensors, dimming systems, relay panels, and smart lighting devices.
  • Translate design intent from project documents into detailed, constructible prefabrication packages for lighting controls.
  • Coordinate with Procurement to verify material selections, substitutions, and lead times for lighting control components.
  • Ensure all lighting control documentation complies with NEC and project specifications.
  • Collaborate with other designers to ensure lighting control systems integrate seamlessly with related assemblies such as wall rough and power distribution.
• Collaboration, Quality, and Continuous Improvement
  • Collaborate with VDC to incorporate redlines, as‑built updates, and digital coordination models into prefabrication packages.
  • Gather and document field feedback and lessons learned to drive continuous improvement in prefabrication design quality and constructability.
  • Partner with Quality Coordinators and Lead Designers to align advanced prefabrication packages with company standards.
  • Contribute to the development and standardization of prefabrication assemblies and catalog items for reuse across projects and regions.
  • Provide technical guidance and mentorship to field, shop, and design personnel on prefabrication standards, tools, and best practices.
  • Identify and develop new prefabrication opportunities that enhance safety, reduce labor hours, or improve installation efficiency.
• Make decisions in an attentive and safe manner to ensure the safety and health of self and others.
• Utilize LEAN concepts or other continuous improvement methodologies to ensure the most efficient operations, processes, and activities.
• Promote and model the Company mission, vision and values through exercising sound and ethical business practices, championing all elements of diversity, equity, and inclusion (DEI) and providing high quality services and programs as they relate to clients, subcontractors, co‑workers, suppliers, and the public.
