Technology Integration

Planning and technology selection is usually the most critical step

17. Requires in-depth understanding of technology and design factors 18. Design & Engineering to reduce project cost and implementation risks 19. Optimization of project design for streamlining project implementation 20. Ensures that designer is ultimately responsible for quality performance 21. Higher plant operation efficiency 22. Continued client interaction 23. Least downtime 24. Higher efficiency due to in-depth understanding of assets created 25. Preparation of AMP (asset management plans) for optimizing O&M activities 26. Civil and bought out portion entirely outsourced to dedicated localcontractors 27. Technology Integration involves: 28. Piping 29. electrical 30. Instrumentation 31. Allows to optimize project construction time and quality
