All the basic studies required to support a Basic Engineering Design Package (BEDP) containing all data needed by a competent contractor to perform the Detail Engineering. According to the nature of a project, engineering studies will include all or part of the following steps:
- Civil and Building design
- Tower/Vessel./Exchanger Design
- Planning and piping Design
- Heater Design
- Instrument Design
- Electrical Design
- Rotating Design
- Insulation Design
- Transportation Planning
- Construction Planning
Each Design Engineer assigned in each department for the project is responsible for preparation of specifications and drawings, technical requisitions and bid evaluation. Equipment Engineering drawings and Manufacturing Drawings are required to manufacture and assemble the parts to produce an operable piece of equipment. Piping drawings, which represent piping layouts for architectural plans and plant layouts, are also needed not only for the procurement of piping materials but for the construction of the final plant. Details of Instrument/Civil/Electrical design are also worked out on the drawings for the construction in this detailed engineering stage. Requirement for transportation, construction, plant operation and maintenance shall, naturally, be incorporated in the detailed engineering design. The detailed design however, could not be completed without the feedback from various specialists who interface in the matrix network organization. Furthermore, it is sometimes required to have discussions with manufacturers, and if necessary, to change the design in accordance with the information from manufacturers, as well as from Licensors and subcontractors. Since the execution of detailed design is a complex group effort, a project engineer has to grasp the overall process design, and control and manage the Total System Engineering which is a lubricating oil for a smoothly functioning project.
