These professionals play a crucial role in designing, documenting, and supporting the installation of E&I systems in industrial, or residential projects.
Job Specific:
Primary
This scope of work entails updating drawings to reflect simple modification tasks. A simple modification refers to changes authorized by the engineering team to be executed by on-site personnel or the team overseeing the facilities. Upon completion of such modifications, all relevant drawings and documents must be updated to accurately represent the changes, ensuring alignment with the as-built drawings. This process is critical to maintaining accurate and up-to-date records of the facility.
Secondary
- Develop detailed 2D and 3D CAD drawings for electrical wiring, instrumentation layouts, and control systems.
- Create schematics, single-line diagrams (SLDs), panel layouts, and termination drawings.
- Design cable tray layouts, routing plans, and wiring interconnections.
- Work closely with electrical and instrumentation engineers to ensure designs align with project specifications.
- Interpret and convert engineering notes, sketches, and specifications into technical drawings.
- Draft P&ID (Piping and Instrumentation Diagrams) for process control systems.
- Design layouts for field instruments, control panels, junction boxes, and PLC/DCS systems.
- Ensure drawings adhere to industry standards such as IEC, NEC, or IEEE.
- Comply with safety regulations and quality control requirements.
- Maintain and update project documentation, including revisions and as-built drawings.
- Ensure proper version control of all technical documents.
- Update drawings to reflect site modifications or changes in project scope.
- Prepare material take-off (MTO) lists for cables, conduits, and E&I components.
- Coordinate with procurement teams for material selection and compatibility.
