Undertake hydraulic transient and surge analysis using specialist software (HAMMER, or equivalent); recommend and specify appropriate surge suppression equipment and protection strategies.
Coordinate mechanical design interfaces with civil/structural, electrical, instrumentation, and SCADA disciplines, support authority submissions, and client technical review meetings.
Provide construction-stage technical support, including review of contractor submittals, shop drawings, and O&M documentation, and attend site visits for the major mechanical plant.
