  • Review P&IDs and piping layouts and assess piping interfaces with existing plant and equipment.
  • Support piping material selection, line sizing and hydraulic or pressure-drop calculations where required.
  • Review equipment layouts, general arrangements, mechanical drawings and vendor documentation.
  • Undertake site inspections, equipment assessments and field verification of existing mechanical and piping systems.
  • Assess interfaces with existing equipment, structures, piping, utilities, electrical systems and site operations.
  • Coordinate mechanical and piping requirements with process, electrical, instrumentation, civil and structural disciplines.
  • Review supplier and contractor technical information against project requirements.
  • Participate in design reviews, constructability reviews, risk assessments and technical workshops.
  • Respond to technical queries and requests for information arising during implementation or construction.
  • Provide engineering support for installation, testing, commissioning and handover activities where required.
  • Maintain clear records of engineering calculations, assumptions, decisions and design changes.
  • Apply applicable mechanical and piping standards, Beca quality procedures and site health, safety and environmental requirements.
