Hello, I reviewed your requirements, and the core challenge is coordinating the complete electrical and HVAC design while fitting the ductwork within the constrained 600 mm by 1,000 mm service space without conflicts with architectural and structural elements. I would develop the load calculations, layouts, SLDs, cable sizing, duct sizing, equipment schedules, BOQs, specifications, and coordinated drawings in line with the applicable IEC, ASHRAE, NFPA, and local requirements. I have worked on similar MEP coordination, electrical design, HVAC layout, and engineering documentation projects and can share relevant examples once we connect in chat. Also a quick question, do you already have the architectural and structural drawings available with reflected ceiling plans for the coordination work? Best Regards, Muskan

The specific risk is accurately calculating electrical loads and sizing HVAC equipment for your system, so I handle this with direct calculation using established engineering principles and then verify through cross-referencing equipment specs. I will build the Electrical and HVAC design package using AutoCAD to produce the lighting and power layouts, socket and equipment layouts, and HVAC layout drawings, also performing the cooling and heating load calculations and AC equipment selection and sizing you require. What is the existing building envelope condition or are there specific insulation values to factor into the load calculations? I need the building dimensions and room usage from you to begin. I have a 5.0 rating across 10 reviews on here, and Preferred Freelancer status.
