• Design and specification of:
• HVAC systems
• Heating and cooling systems
• Medical gas systems
• Wastewater and drainage services
• Mechanical pipework and associated services
• Undertake heating and cooling load calculations to establish system requirements.
• Carry out airflow and pressure-loss calculations for HVAC and ventilation systems.
• Undertake pipe sizing and hydraulic calculations for mechanical and medical gas systems.
• Calculate pump flow rates, system duties and pressure requirements.
• Undertake duct sizing and air distribution calculations.
• Develop mechanical system layouts and ensure designs are coordinated with other MEP disciplines.
• Prepare and update MEP drawings, including layouts, schematics, sections and details.
• Produce design documentation, calculations, schedules and technical specifications.
• Coordinate designs with architectural, structural, electrical, process and other engineering disciplines.
• Support the preparation of technical documentation for tender, procurement and construction.
• Provide technical support during construction, installation and commissioning activities.
• Liaise with contractors, vendors, client representatives and project teams to resolve technical queries and design issues.
• Work within a GMP and EHS-focused pharmaceutical environment, ensuring designs consider operational, safety, maintainability and compliance requirements.

Key Skills & Experience
