A mechanical engineering consultant is responsible for design, planning, and technical advisory services, ensuring systems are safe, efficient, and compliant.

Key Responsibilities:

• Feasibility studies and load calculations
• Design of HVAC systems, plumbing, firefighting, and gas systems
• Design of industrial mechanical systems (piping, pumps, compressors, boilers, turbines)
• Preparation of drawings, technical specifications, and BOQs
• Energy efficiency and sustainability analysis
• Compliance with codes, standards, and regulations (ASHRAE, NFPA, ISO, etc.)
• Tender evaluation and contractor selection support
• Site supervision and inspection during installation
• Testing, commissioning, and performance verification

👉 The consultant ensures mechanical systems are safe, efficient, reliable, and cost-effective

A mechanical engineering contractor is responsible for procurement, installation, and execution of mechanical systems on-site.

Key Responsibilities:

• Installation of mechanical systems as per approved designs
• Procurement of materials, equipment, and machinery
• Site management of labor, tools, and machinery
• Fabrication and erection of piping, ducting, and mechanical structures
• Implementation of health, safety, and environmental (HSE) measures
• Quality control and inspection during installation
• Testing, commissioning, and handover
• Maintenance support and troubleshooting

👉 The contractor transforms the design into operational systems.

In Design–Build or EPC contracts, one mechanical engineering firm may act as both consultant and contractor, offering:

• Single-point responsibility
• Faster execution
• Reduced coordination issues
• Optimized system performance
