Plant 3D design

The model, the clash report, the isometrics and the steel detailing — produced by the firm that also checks whether the design works.

Most plant design offices model geometry. Ours sits alongside an analysis practice led by a NAFEMS PSE Assessor, so a layout question with a stress or flow implication gets answered rather than assumed.

Why this exists

For most of IDAC's history, clients brought us a design and asked whether it worked. Plant 3D design is the other half of that: we produce the design too, and hold the model to the same review standard as the calculation.

The practical benefit is a shorter loop. When a clash resolution moves a line and changes a support load, or a layout change affects thermal growth, the check happens internally instead of going back to a separate consultant. Fewer handovers, fewer assumptions crossing an organisational boundary.

Anchored in process and CBG plant. India's mandatory biogas blending obligations have created a design pipeline larger than the country's available plant-design capacity. IDAC has already delivered EPC support for a 10 TPD compressed biogas plant through a project-based ODC.

What the practice delivers

3D plant modelling

Equipment, piping, structures and access modelled in a single coordinated environment, from plot plan through to a model that can be reviewed, clashed and issued.

Clash detection and coordination

Systematic clash testing across disciplines, with a resolved clash report rather than a raw list — including the design decisions taken to clear each one.

Structural steel detailing

Pipe racks, platforms, access steel and skid frames detailed to fabrication, coordinated with the piping and equipment model.

Drawing and document production

Isometrics, general arrangements, plot plans and material take-offs extracted from the model, with consistent annotation and revision control.

How a project runs

  1. 01

    Setup and standards

    Project environment, specification library, layer and naming conventions, drawing numbering and ISO configuration established before modelling starts — the stage that determines whether the rest of the project runs cleanly.

  2. 02

    Layout development

    Plot plan, equipment arrangement and primary routing, reviewed with you before detail modelling begins.

  3. 03

    Detail modelling

    Piping, supports and structure modelled to the agreed specification, with progressive internal review rather than a single check at the end.

  4. 04

    Clash and review

    Coordinated clash testing and model review sessions, with resolutions documented.

  5. 05

    Issue

    Isometrics, GAs and take-offs extracted, checked and issued under revision control.

The team

The practice is built around a lead engineer who owns the project environment — specifications, catalogues and drawing configuration — supported by design and graduate engineers. That structure is deliberate: in plant design, most quality problems trace back to an environment that was set up in a hurry.
