• Coordinate security design information with EICA, civil, structural, mechanical, process and other engineering disciplines.
• Review drawings, specifications, survey information and technical documentation to ensure design information is accurately represented.
• Identify potential design clashes, missing information and constructability issues, raising technical queries where necessary.
• Incorporate approved design changes, supplier information, site mark-ups and survey data into project drawings.
• Support site surveys and design coordination meetings where required.
• Prepare construction drawings and verified as-built documentation.
• Maintain drawing registers, revisions, document references and associated project information.
• Ensure all drawings and models comply with relevant client requirements, company procedures and project CAD standards.
