The HHT Basic Engineering Packages define the purpose, content and structure of the process and overall design specifications. It emphasizes the importance of maintaining the project’s technical direction as defined in the Basic Design Phase and it also provides definitive direction and sufficient details to ensure the progression of subsequent phases. During this phase the following key components take place:

  • Project kick-off meeting
  • Flow sheet, material and energy balance development
  • Equipment specification preliminary listing
  • Pipe class reference schedule
  • Valve reference schedule
  • P&ID preliminary diagrams
  • Building layout drawings
  • Layout and piping studies
  • Tie-in schedule
  • Electrical area classification development
  • Instrument schedule created
  • Preliminary I/O schedule
  • Process control system definition
  • Safety concept developed
  • Risk assessment
  • Project procurement plan
  • Initiate procurement process for long delivery equipment
  • Monthly Project Progress Report
  • Conduct Basic Design Review
  • Class A estimate (+/- 10% accuracy)
