Steel pipe rack and process structures at an onshore plant

Structures & Applications

Industrial Structures & Engineering Documentation Applications

Start from the structure you are dealing with. Each one shows which services produce its drawings, models, fabrication information and quantities.

Applications Are a Way In,Not Separate Services

A pipe rack can need a GA drawing, a 3D model, shop and erection drawings and an MTO. Each of those belongs to one service; the paths below show how they connect, so you can scope exactly what you need.

Greenfield Projects

Design documentation, structural arrangement and model development, fabrication and construction detail progression, and initial registers and quantities.

Brownfield Projects

Existing records and verified geometry, approved alterations, interfaces to retained structures, and revised models and record documentation.

Greenfield and brownfield are lifecycle conditions, not separate services. Brownfield Structural Modifications & As-Built Documentation leads existing-plant packages.

Pipe Racks & Pipe Bridges

Pipe rack and pipe bridge packages combine structural framing, equipment and piping interfaces and fabrication documentation. Depending on the project stage, an assignment may involve GA drawings showing bays, levels and framing, a coordinated structural model, engineer-approved connection detailing, assembly and single-part shop drawings, erection plans and material schedules. For an existing rack, verified site information and an approved modification design become critical inputs. Piping stress, pipe routing and rack design calculations are not part of these packages.
