Key Responsibilities

1. Step-by-Step Design Phase

• Phase 1: Requirements & Analysis – Review project specifications, flow capacities, and regulatory standards to calculate fluid dynamics, pressure drops, and equipment sizing.
• Phase 2: Conceptual & Schematic Design – Develop initial mechanical concepts, process flow diagrams (PFDs), and piping and instrumentation diagrams (P&IDs) for water and waste networks.
• Phase 3: Detailed Engineering & CAD Modeling – Create comprehensive 2D/3D layouts using tools like AutoCAD Plant 3D or similar modeling software for piping, ductwork, and equipment placement.
• Phase 4: Equipment Selection – Select efficient pumps, valves, blowers, screens, and chemical dosing systems tailored to municipal or industrial waste demands.
• Phase 5: Technical Documentation – Prepare bills of materials (BOM), technical datasheets, and design calculation reports for procurement and regulatory compliance.

2. Construction & Site Supervision Phase

• Oversee mechanical installation activities on-site to ensure strict alignment with approved design drawings and contract documents.
• Coordinate with civil, electrical, and plumbing teams to resolve clashes and streamline on-site workflow.
• Review contractor submittals, inspect mechanical equipment delivery, and manage Requests for Information (RFIs).
• Conduct site safety checks and enforce compliance with local and international engineering codes (e.g., ASTM, NFPA).

3. Testing, Commissioning & Handover

• Plan and execute hydrostatic testing, flushing, and mechanical run-tests for pumps and piping networks.
• Troubleshoot system anomalies during plant commissioning and hand over fully operational assets to facility management teams.
