IDOM IS WORKING IN BIM FOR THE METROLINK PROJECT (FIRST METRO LINE IN DUBLIN), UNDER BIM LEVEL 2 STANDARDS APPLIED STRICTLY, BEING A REAL HANDS-ON EXAMPLE FOR THE APPLICATION OF THIS PROJECT WORKING METHODOLOGY.
In recent years, in spite of the wide extensive use of BIM for architectural and building projects, BIM for infrastructure projects, and mainly in railway infrastructure projects has been quite limited. This limited use is due to a variety of reasons, being the interoperability and the software selection one of the main, but not the only, barriers.
IDOM is working in BIM for the MetroLink project (first metro line in Dublin), under BIM Level 2 standards applied strictly, being a real hands-on example for the application of this project working methodology.
IDOM’s scope for MetroLink project does not only include the delivery of the preliminary design in BIM. IDOM has also created numerous standards and manuals which will be used by Transport Infrastructure Ireland (TII) for BIM implementation within their organization. Since TII has no previous experience working within the BIM environment, the above-mentioned standards will be introduced and applied to all the organization and they will also be used to carry out any future project promoted by TII as well as for the management of any asset generated along the lifecycle of the infrastructure regardless of their stage.
Although the .ifc format is very often considered as the ideal format to export and import BIM models, this is very often a bit further from the reality. Just as an example, IDOM decided to implement and use imodels for the creation of the federated model which included both metro stations and the rest of the metro infrastructure.
For that reason, it was necessary to create a smart system to guarantee that the model developed from the preliminary stages could be used as the base for a model that could be used during all and every phase of the project: Design, construction and, finally, operation & maintenance. At the same time, this system will allow, in the future, to create a digital twin.
