• Identify any variation request from the standards and codes and alert his/her manager
• Identify, collect and track the requested input data (and review these last ones) in relation with the

coordination team

• Produce / update / optimize / provide support and expertise to the design documentation production related

to the documentation of his specific scope/responsibility.

• Ensure compliance of the design with standards & codes, client requirements, suppliers’ data, taking into

consideration schedule constraints and manager objectives (for instance in terms of budget)

• Until As-built are provided and Final Taking Over (FTO) signed, produce the data requested by the:
  • Coordination department (i.e.: according to updates from civil, architectural, electromechanical, signaling…)
  • suppliers/manufacturer/sub-contractors
  • Procurement department (MTO production, quantities survey, equipment: sizing/ selection/confirmation…)
  • Construction site (providing all the requested design clarifications / clash corrective solutions…)
• Follow-up his/her design until final approval by the client/consultant
• Provide the technical feedback to client/consultant technical comments according to requirements,

standards & codes

• Participate to internal and external meetings to present/defend his/her designed solutions
• Can produce the as-built drawings
• Can participate to the FAT related to the equipment he/she designed
• Actively participate (CRE only) to quality controls under the supervision of the QHSE department;
• Site visits and T&C follow up is such important to designers that the following activities are mandatory;
• Inspect the installation activities: responsible for ensuring that the site activities are implemented according

to the project specification and drawings

• Conduct the required tasks to ensure that the equipment is fulfilling the required properties
• Material Inspection stages:
  • Documents: inspect the supplier documentation to ensure the supplier will provide a material that meets quality standards
  • FAT: check that the factory is suitable to manufacture the required material and follow his documents in terms of quality
  • Material Inspection: perform regular quality assessments on all incoming materials from vendors and outgoing products for shipping
• Test Inspection stages: participle to relevant T&C activities to record the test results
• Produce / update / optimize / provide support and expertise related to:
• Technical specifications: Rectifier Station (RS) and Lighting Power Station (LPS) 20KV switch gear, High
• Voltage Station (HVS) equipment (AC/DC low voltage distribution switchboard, 20KV control command, control monitoring system…)
• Functional specifications and functional analysis: RS, LPS, Workshop, HVS (interlocking; auxiliary), programmable Logic Controller (PLC) Input / Output (I/O) lists…
• Technical files: traction transformers, auxiliaries, 20KV/750V and LV cables, cable trays, low & medium distribution switchboard, HVS equipment…
• Calculation notes: LPS (including Low Voltage (LV) power balance), lighting system, LV and 20KV cable sizing, voltage drop & short circuit), power balances, soil resistivity and earthing…
• Drawings, schematic, single line diagram (rectifiers, RS, LPS, lighting, PLC control cable list…), and diagrams
• Prepare the cable lists and routing for MV, LV and Traction
• Selection of detailed drawings, Shop drawings, nomenclatures, workshop equipment…
• Actively contribute in configuration control (in terms of equipment)
• Analyze/track the client requirements (including tender technical document) and ensure the proposed

design is compliant (propose corrective/innovative solutions if needed)

• When identified, propose innovation
• Report his/her activities (progress, variations, technical issues…) to his/her manager

Alert in case of risk identification (schedule, design, equipment…)
