Piping and ducts in an operating drying area, with walkways and supporting steel structures

Service · Engineering

Engineering for every discipline in a single 3D model, from conceptual study to detailed engineering

ProHolz engineers new industrial plants and leads the engineering of expansions, modernizations and upgrades of plants in operation. Procurement and construction stay with the client.

How we work

One model coordinates the disciplines, and the construction drawings come from it

All disciplines work in a single 3D model, and it produces the 2D deliverables used on site: plan drawings, isometric drawings, bills of materials, and fabrication and erection drawings.

The model coordinates the interfaces between disciplines and with equipment suppliers. Every document has a controlled number, revision and history, from the first issue for comment to the as-built issue, so that the client, the suppliers and the site always work from the same version.

In the Sudati MDF 2 project, a single BIM model covers the layout, press, dryer, evaporator and dust extraction.

ProHolz engineers and manages; procurement and construction stay with the client.

Phases

Five phases, from conceptual study to start-up

  1. 01

    Conceptual study

    Master plan, general arrangement and internal plant logistics.

  2. 02

    Basic engineering

    Process flow diagrams, mass and energy balances, and process specifications.

  3. 03

    Detailed engineering

    Plan drawings, isometric drawings, bills of materials, and fabrication and erection drawings.

  4. 04

    Construction monitoring

    Design revisions controlled through to as-built. Construction supervision is part of project management.

  5. 05

    Start-up

    Support for commissioning, start-up and training, also under project management.

Disciplines

Eight disciplines in the same model

Process
Process flow diagrams, piping and instrumentation diagrams, mass and energy balances, and process specifications.
Layout and master plan
Master plan, general arrangement and internal plant logistics.
Civil and architecture
Earthworks, foundations, and industrial and administrative buildings.
Steel structures
Process buildings, pipe racks and supports, with wind and seismic loading, plus the fabrication and erection drawings.
Mechanical and piping
Industrial piping with isometric drawings, bills of materials and stress analysis, plus utilities, ducts and pneumatic conveying.
Electrical and automation
Medium and low voltage, substations, retrofit and control.
Fire protection
Hydrant and sprinkler systems.
3D model and point cloud
A single coordinated model of all disciplines and, in existing plants, laser scanning.

Operating plants

In an existing plant, the design starts from what was built

When the plant already exists, the starting point is a laser scan of what has been built. The point cloud gives the design the actual geometry and allows the tie-ins to be planned to fit within the shutdown window.

Equipment from different suppliers, including imported and refurbished units, is integrated into the local engineering. The scope also covers the analysis of the electrical and thermal efficiency of production and the identification of operational bottlenecks.

This was the case at Louisiana Pacific OSB, with a refurbished multi-opening press, and at Chilepanel OSB, the expansion of a plant in operation.
