Magne Ganz, BIM Specialist at Multiconsult, gave a great demonstration at BILT Europe 2024 in Riga on May 9. He explained what it took to understand the client’s BIM plan on Oslo’s Fornebubanen job.
The Fornebu Line is the latest inclusion to Oslo’s rail network. When completed in 2029, it will be a 7.7-kilometer-long underwater line with six channels.
For the design initiative, Multiconsult and COWI collaborated. The 500-strong, 12-discipline style group includes professionals, managers, devices, and BIM supervisors. It collaborates across five Western nations.
The employer’s vision and BIM method
The buyer, Etat Fornebubanen, is a partnership between Oslo and Akerhus communities. Their guiding principle for the job is that “innovative partnership creates the train of the future.”
The steps involved in achieving that perspective are described in the BIM plan:
- The customer wants to use BIM and other scientific tools to improve processes and contribute to the development of the industry from a modern perspective.
- Designs are required to be used as much as feasible for all job stages and assent bodies.
- To facilitate visible communication with stakeholders and buildability analyses of the design phase, a link between the building schedule and the design will be made.
The professional execution
Magne’s demonstration clarified the wide range of modern, administrative, and managerial automation that must be mastered to total the client’s vision.
The pattern team work on a Common Data Environment, but it’s not a solitary shared area. It comprises eight systems: Teams/Sharepoint, BIM 360 Docs, BIM 360 Collaborate, Trimble Novapoint Quadri, File site, BIMCollab Cloud, dRofus Asset DB, and Omega365.
One BIM may not respond to all requirements, either. Until 2024, Navisworks and Solibri were the principal tools. Scandinavian Novorender is used from 2024 until it is older because it is more compatible with all devices. On the building site, companies use some other BIM audiences.
The job provided screens that can be used to display crucial details about the numerous models and their statuses.
The BIM technology
The project’s BIM technology lineup includes several different ones.
- ArcGIS + FME for chart data and existing properties
- Revit for train style (architect, fundamental, MEP, fireplace &, health )
- Network and rail design using Novapoint / Civil 3D.
- Tekla for pipe institutions.
All the concepts were geolocated using Euref 89 – NTM 10 and NN 2000 systems.
Magne utilized pitcher documents and Windows Task Scheduler for model coordination, immediately running design updates immediately. He likewise mentioned how Grasshopper, Dynamo, and Python were used for various design technology tasks.
4D and 5D Vo
Magne shared insights on how to use 4D (time ) and 5D ( cost ) BIM successfully. He pointed out that it is important to use business classifications, label the elements according to the price breakdown structure, and try to tear down the models as they are constructed.
With the same Work Breakdown Structure script, type parts were matched with tasks and techniques in the plan for 4D.
The cost calculation actions included BIM modeling, production to IFC / OpenBIM, and using ISY Calcus for price and CO2 computations.
In a strange coincidence, ISY Calcus ‘ unit prices were subsequently incorporated into Revit to allow designers to calculate actual costs as they altered or revised the model.
Takeaways
In this description, I touched on only some technical elements of the display.
Magne emphasized that a designer’s and contractor’s BIM requirements must be clearly defined, as well as having the appropriate degree of technical maturity. For the property ‘ lifecycle needs, complete as-built documents is also required.
Fornebubanen demonstrates how attentive professionals like Magne and visionary clients are transforming our business.
