​

Technical Drawing Production

• Produce accurate, fully dimensioned engineering drawings using CAD software (AutoCAD, SolidWorks, or equivalent in use) including: general arrangement (GA) drawings, detailed component drawings, assembly drawings, fabrication drawings, and installation drawings.
• Produce and maintain Piping and Instrumentation Diagrams (P&IDs) for refrigeration systems, IT and Electrical lines, drainage systems, and compressed air systems in collaboration with the relevant engineers.
• Produce electrical schematics, single-line diagrams, panel layout drawings, and cable routing plans in collaboration with the Electrical Engineer.
• Develop workshops, depot, and facility layout drawings including equipment positions, access routes, drainage, and safety zone markings.

Drawing Revision Control & Document Management

• Maintain a comprehensive, version-controlled drawing register covering all engineering assets — ensuring every drawing has a unique number, current revision status, issue date, and authorization record.
• Implement and enforce the organization’s drawing revision control procedure: no drawing is re-issued without a formal revision cloud, revision index update, and superseded-copy withdrawal.
• Administer the drawing archive (electronic and hard copy where required), ensuring drawings are filed, searchable, and backed up in accordance with document retention policies.
• Collect and incorporate as-built mark-ups from site engineers and contractors following installation or modification works, updating the record drawings to reflect actual installed conditions.
• Periodically audit the drawing archive to identify obsolete, missing, or unapproved drawings and take corrective action to maintain archive integrity.

Site Surveys & As-Built Documentation

• Conduct site surveys and physical measurements of plant, equipment, and workshop facilities to produce accurate as-built drawings where original documentation is unavailable or outdated.
• Use appropriate measurement tools — tape measures, laser distance meters, vernier callipers — to capture precise dimensions for drawing production.
• Photograph and document existing installations to support drawing production and asset documentation programmes.

Technical Standards & Drawing Quality

• Apply and enforce engineering drawing standards across all produced drawings — including ISO 128 (technical drawings), ISO 3511 (P&ID symbols), IEC 60617 (electrical symbols), and any company-specific drafting standards.
• Check all drawings prior to issue for accuracy of dimensions, tolerances, material specifications, surface finishes, weld symbols, and title block information.
• Develop and maintain drawing templates, title block standards, symbol libraries, and CAD layer conventions to ensure consistency across all engineering documentation.

Project & Maintenance Support

• Provide drawing support for planned maintenance shutdowns, plant modification projects, and capital engineering works — producing drawing packages on time to support project schedules.
• Participate in engineering design reviews, providing draughting input and flagging any constructability or drawing-standard issues before drawings are issued for construction or fabrication.
• Support the preparation of maintenance procedure documentation, SOPs, and work instruction diagrams that aid technicians in carrying out complex maintenance tasks safely and correctly.
• Assist in the preparation of equipment specifications, Bills of Quantities (BOQs), and parts lists derived from engineering drawings for use by procurement and stores.

Knowledge Transfer

• Provide guidance and on-the-job coaching to technicians in CAD tools, drawing standards, and document management practices where applicable.
• Conduct periodic drawing quality reviews and provide constructive feedback to improve the standard of technical documentation across the maintenance team
