Quick answer
Process Plant Structures covers designing multi-level process structures, technological platforms and access steel. Done properly, it follows AISC 360, EN 1993, IS 800 and produces lod 400 tekla 3d model that a fabricator or reviewer can use without rework. Structural Engineering Services delivers process plant structures to clients in 40+ countries with a senior-engineer review on every package.
The standards that govern process plant structures
Process Plant Structures is governed by AISC 360, EN 1993, IS 800, AWS D1.1. Which one leads depends on the project location and the owner's specification — a US refinery package and a European commercial building may need the same discipline executed to entirely different rules.
Beyond the headline code, most projects layer client specifications on top: operator standards (Shell DEPs, Saudi Aramco SAES, ADNOC), fabricator preferences and local authority requirements. A good process plant structures partner maps all of them into a compliance matrix at kick-off.
How code compliance is demonstrated
Compliance is shown through documentation, not assertion. Your package should include:
- Design basis / basis-of-design note referencing the governing code and edition.
- Calculation reports with load combinations and acceptance criteria.
- Drawings flagged with the applicable code and material grades.
- A documented checker's review with sign-off.
- Revision-controlled transmittals so the latest code-compliant issue is unambiguous.
Common compliance mistakes
The most frequent compliance failures we see in process plant structures are edition drift (working to a superseded code edition), mixing code systems mid-package, and missing project-specific overlays. Each is avoidable with a kick-off compliance matrix and a senior review gate.
Working across multiple jurisdictions
Global projects often need one package that satisfies several jurisdictions. We deliver process plant structures to AISC 360 and EN 1993 routinely and maintain checklists for each, so multi-code packages are reviewed against every governing standard, not just the primary one.
