Structural Steel

Frames, platforms and pipe racks that carry the plant.

01Overview

Structural steel sets the geometry every other discipline has to live with. If the frame is out, the piping is out, the cable tray is out, and the equipment does not land on its bolts.

Plejad provides steel erection crews for primary and secondary structures, platform and access works, and the modifications that a live plant constantly generates.

02Capabilities

What this discipline covers.

  • 01Erection of primary and secondary structural steel
  • 02Pipe rack and support structure assembly
  • 03Platforms, stairs, ladders and access walkways
  • 04Bolted and welded connections to specification
  • 05Modification and reinforcement of existing structures
  • 06Setting-out, alignment and dimensional checks

03Typical scope

Work packages typically contracted under this discipline.

  • New pipe rack for a process expansion
  • Equipment support structures and skids
  • Access platforms around vessels and columns
  • Structural modifications for a plant retrofit
  • Replacement of corroded secondary steel

Scope is confirmed per project. Capabilities listed here are indicative and adjusted to the specification, permit regime and client procedures of each site.

04Execution approach

How the discipline is planned, staffed and closed out.

  1. 01

    Survey before steel

    Foundations and existing interfaces are surveyed first — steel is not the right place to absorb somebody else's tolerance.

  2. 02

    Lift planning

    Erection sequence, crane positions and exclusion zones are agreed with the site before the first piece leaves the laydown area.

  3. 03

    Connection integrity

    Bolted connections are torqued and recorded; welded connections follow the qualified procedures and the agreed inspection level.

  4. 04

    Handover geometry

    Structures are handed over with dimensional checks completed, so the following disciplines start from a known position.
