Detailed Design & Drafting

Many developments we are involved in progress to detailed design, drafting and construction management after we have completed the concept and FEED stages.

GPA provides detailed design across the following disciplines:

  • Mechanical
  • Civil/Structural
  • Instrumentation
  • Electrical, HV, LV, ELV
  • Automation and SCADA
  • Process

Our team of design drafters specialises in using 3D CAD for mechanical/piping, electrical/instrument and civil/structural drafting. GPA also makes extensive use of laser cloud scan and survey data of existing brownfield sites to enhance the accuracy and efficiency of complex 3D drafting/modelling.

GPA develops design packages including fabrication and installation scopes of works, work packs and specifications, supported by detailed construction drawings, piping plans, isometrics, BOMs, detailed E&I and control system drawings, civil and structural detailed drawings.
