Automotive plant expansion

Client: Pallér Csarnok Kft.

Size: 1780 m2

Location: Nyíregyháza

Completion: 2023

Architect: Csaba Livják

We were commissioned to prepare the general design for a global tyre manufacturer company’s planned 2023 factory expansion in Nyíregyháza. The BIM model was delivered with ISO 19650 document management and LOD 400. The bilingual project was fundamentally determined by the complexity of design & build and the need to meet strict client requirements.

The project

The client wanted to expand their existing hall with a new building due to a technology change. The architectural appearance and massing of the new part of the property were designed to match the existing building in terms of materials and height, in the colors of the client’s international brand, based on the approved tender design.

The project included the construction of a new single-bay hall and two annexes (rest block and storage room, switch room), together with the necessary building services and electrical installations.

BIM Execution Plan (BEP)

The investor’s BIM protocol precisely defined the requirements for the project, for which our solution was proposed in the BEP. Accordingly, the building model was made suitable for other simulations of the building’s operation, for on-site BIM-based construction coordination and was prepared to be further developed into a realization model. The central model was designed to be classified up to level 3 according to the uniform classification scheme.

The digital ecosystem is designed to be a flexible system, combining the principles of open BIM and closed BIM, so that it can integrate additional project participants at any time. Software used in this project:

  • static: Allplan, Tekla
  • architecture, mechanical and electrical engineering: Revit
  • fire protection, road and pavement: AutoCAD
  • BIM coordination: Navisworks
  • CDE: Dalux

Common Data Environment (CDE)

An important feature of a well-functioning BIM methodology is that

  • all data comes from the same source
  • data is regularly updated
  • their visibility to stakeholders must be ensured through rules.

For these reasons, Dalux was also used as the Common Data Environment for this project, because the transparency, easy accessibility, and manageability provided by the software make the implementation of the undertakings very smooth.

Document management and approval process

The aim was to give participants access to the information they needed without the use of special (e.g. discipline-specific) software. To get the stakeholders up to speed with Dalux, we have organized training. As a result, all stakeholders can easily access the current plans from anywhere (office, on the move, on the ground), and can comment or manage changes from their smartphone or tablet.

In Dalux, the approval process is set up for the six levels of the project organisation (Client – Project Manager – Technical Inspector – Contractor – General Designer – Branch Designers). We have also defined the storage location of files in different statuses (work, shared, accepted, delivered), the identity and order of approvers, and change management rules, which allowed us to avoid misunderstandings from time-consuming phone calls and emails.

We used bilingual (English, Hungarian) settings in the interface so that project participants with limited or no language skills could filter and view documents easily.

Scan to BIM

At the start of the project, we carried out a point cloud survey of the existing property, detailing and showing in a CDE environment the exact location of the fire protection, mechanical and electrical equipment to be relocated on the front wall of the existing hall. We then built a 3D, detailed BIM model of the new part of the plant in LOD400.

We shared the current plans on the Dalux interface so that the parts to be demolished, moved, or replaced were visible and identifiable.

For example, the shutter gates and escape doors in the old hall were used in the new extension for cost-efficiency reasons (red: to be demolished, blue: to be incorporated).

With the information shared and a consistent approval process, decisions could be made clearly and transparently for all phases, so the implementation was smooth and without any disruption.
