Engineering – Construction

From basic to detailed engineering: the basis is the flow diagram

The basis of every engineering project is the flow diagram (P&ID/R&I). The flow diagram is thus a central document for process engineering plants and contains all details about a plant – simply and clearly. It forms the basis and graphically represents the structure and function of a plant.

Depending on the project status, the P&ID contains all details on the designations of components, nominal sizes and functions of components (electrical as well as mechanical). The finished flow diagram reflects the functionality of their entire plant.
In this case, Wellmann uses Autodesk products so that you have planning security in the future.

Customized plant design

Using the latest 3D solutions, process engineering plants are planned, developed and designed down to the last detail. Wellmann has specialized in the use of Autodesk products and has been working with Plant 3D and Inventor for years. You as a customer do not take any risk, because these software packages are state-of-the-art.

With our specialists we are able to support our customers holistically in all areas of process plant engineering. To ensure quality, Wellmann relies on Pro.File as its PDM system. All your data is stored centrally and monitored by a defined workflow management, so that only what has been approved and checked is manufactured.

The central data handling helps especially in the reduction of lead times. Drawings are always based on as much existing data as possible. Your project can thus be carried out quickly and cost-effectively.

Engineering in 3D model: from concept to on-site implementation

In modern, digital project management, all trades must be integrated into a holistic 3D planning process in order to reduce project lead times.

Together with the customer, the appropriate tool landscape is determined at the start of the project and the standards in the 3D model are defined. Wellmann Engineering therefore relies on the BIM concept (Building Information Modeling) in 3D planning. The BIM model is adapted in the project entirely according to their requirements.

The BIM model can be created based on an existing building by a 3D scan or redrawn from scratch. This allows you to determine in advance how piping runs, staging, tank placement and component placement can be done. Your digital twin is thereby continuously developed until the end of the project.
