The implementation of OPEN BIM has been instrumental in advancing the large-scale mixed-use Tripla complex in Helsinki, Finland.
The Tripla complex features a bold design comprising three interconnected buildings, bridging the east and west sides of the Pasila district, which was previously separated by an abandoned railway station. This comprehensive development includes office spaces, shopping centers, conference facilities, residential units, hotels, multifunctional sports venues, and public transportation hubs.
The project’s goal is to foster sustainable growth in Helsinki’s city center while establishing a new, diverse urban lifestyle pattern.
BIM Application Provides a Strong Foundation for the Tripla Project
At the project’s outset, the owner mandated that all designers adhere to the “General BIM Requirements” – Level 3, as published by BuildingsMART Finland. To ensure compliance with these universal BIM standards and clarify the required level of detail within the models, the project’s BIM coordinator developed a comprehensive BIM implementation plan.
ARCHICAD Collaboration and OPEN BIM Enable Overcoming Technical Challenges
Architect Kalle Soini explained, “Given the project’s scale, we had to carefully manage file sizes during the initial design phase. To maintain smooth operation, we divided the complex into three main models. Most floor plans are stored in separate files, which include only the relevant floor plans and PMK files generated from these models.”
The project team extends beyond architects to include structural engineers, mechanical specialists, and numerous other professionals and consultants. To streamline workflow management across this vast project, an independent company handles overall BIM coordination. The exchange of IFC documents has been crucial for sharing cost estimation data.
The client utilizes Solibri Model Checker and Tekla Structures to organize the construction schedule. Architects integrate IFC and DWG files into their ARCHICAD models. According to Kalle Soini, “ARCHICAD offers great flexibility, allowing us to split information into smaller fragments, with most data stored across multiple model files.” The IFC files are generated directly from ARCHICAD.
Design departments consolidate all IFC files every one to two weeks and feed them into the Solibri Model Checker. This combined model primarily supports daily quality control and helps resolve design issues during project meetings. Using ARCHICAD simplifies and streamlines the process for clients and various design teams to access and unify information within the IFC files.
