Basic Engineering

The choice of variants for the technical plant execution of a plan will be prepared by GID within the framework of basic engineering. Thereby, the customer’s desired options and degree of flexibility is taken into consideration.

 

The planning documentation puts the customer in the position to confidently estimate the investment costs and to commission the execution planning for the next planning phase.

 

Process engineering is the lead engineering discipline in this planning phase. While the general and 2D project planning is defined clearly as a technical scheme with flow diagrams, specifications and lists, the 3D installation planning creates the first detailed visualisation of the buildings, apparatus, infrastructure and load-bearing structures.

 

Key steps and documentation are:

 

Project Management and Controlling

  • Kick-off meeting
  • Regular project meetings
  • Progress reports regarding documentation and planning status
  • As-is analysis
    • With the support of engineering disciplines as required
  • Time scheduling for Basic Engineering within the framework of the complete scheme

 

Process Engineering

  • Process simulation
  • Material and heat balance
    • Material data
    • Main material flow
    • Supporting materials
    • Energies
  • Process flow diagrams up to final release
  • Piping classes and piping class selection
  • Hydraulic calculations
  • Piping and instrumentation diagrams
    • At least in the first version
  • Piping lists
  • Integration point list
  • Measurement statement piping (80%)
  • Technical safety inspection
    • Such as safety meetings, audits, HAZOP etc
  • Process data sheets for electrical, instrumentation and control tasks
  • General plant descriptions
    • Process descriptions
    • Constraints in connection with the plant
  • Identification of the applicable laws, regulations, guidelines and technical rules and standards
  • Relevant authority documentation
    • Process flags
    • Data for application forms

 

Mechanical (apparatus and machines)

  • Specification of apparatus and machine execution in the operations unit
    • Up to inquiry specification
    • Merging of package units
  • Apparatus lists

  • Static calculations under design load for
    • Footing and foundation
    • Load-bearing structure dimension
  • Construction descriptions

    • Cement construction
    • Steel construction
    • Infrastructure (streets, paths, drainage etc)

 

Electrical, Measurement and Control Technology

  • Electrical supply concept
    • Distribution
    • Transformation
    • Installation concept for switch plants
  • Consumption list
  • Single line diagram
  • Specification based on available apparatus and machines
    • Up to inquiry specification
    • Transformers
    • Motors
  • Measurement and Control Technology / Process Control
    • Plant process control
    • Instrumentation
    • Supporting materials and energy to control and regulate
  • Measurement point lists
  • Flow diagram presentation for measurement and regulation functions

 

 

 

 

Investment cost estimations

Within the framework of basic engineering, GID produces investment cost estimations which reflect the scope of information at this decisive point in the project:

  • Mainly by price investigation based on inquiries for:
    • Apparatus
    • Machines
    • Assembly
  • And where necessary, price investigation based on reference projects or by estimation

The generally available information for the technical scope at that point in time allows a confidence interval of up to 10%. From case to case, based on particularly good or particularly volatile input information, the fluctuation of individual prices can be better or worse.

 

GID can also produce these cost estimations according to the UNIDO guidelines.
