  3. 3. Introduction Crusell Bridge Data: Type & Location • Type: cable-stayed bridge • Consist of two asymmetrical cable-stayed spans: measuring 92 m and 51.5 m (the total length is 143.5 m) • Connects the western edge of Jätkasaari with Ruoholahti, FinlandiaPicture: 2/22

  5. 5. Introduction Crusell Bridge Data: Background • The Crusell Bridge becomes the most prominent bridge in Finland to be designed and built using BIM (Building Information Model) • The design is solicited by the owner in a design competition announced in the winter of 2001Picture: 4/22
  6. 6. Introduction Crusell Bridge Data: Background • The competition aimed to find a quality bridge solution that would bring out the characteristics of the area and take into account the requirements of the landscape • Although a British design firm win the competition, the project is awarded to the second place winner: WSP FinlandPicture: 5/22
  7. 7. Introduction Crusell Bridge Data: The Use of BIM • During the design and construction process,the project team implementing both BIM technologies and lean construction principles and toolsPicture: 6/22
  8. 8. Introduction Crusell Bridge Data: The Use of BIM • This case study focuses on the construction stage of the project, highlighting two aspects: 1. The extensive use made of the BIM: - For fabrication of steel girders and concrete reinforcement - For monitoring and management of the supply chain of fabricated components - For formwork and temporary support structure design - For quality control using laser scanning, and - For construction planning using 4D animation; 2. The ways in which BIM supported lean construction practices, such as its support of production management onsite using the Last Planner System™.Picture: 7/22
  9. 9. BIM Learning Experience A Building Model Supports a Wide Variety of Information, Uses of BIM in the Construction Stage • The Crusell Bridge project becomes a BIM learning process for everybody involved, even for those who had previous experience using BIM, because many new solutions and techniques were tried • For the client (City of Helsinki’s public works department), it was first bridge project using comprehensive BIM, including time and management dimensionsPicture: 8/22
  10. 10. BIM Learning Experience A Building Model Supports a Wide Variety of Information, Uses of BIM in the Construction Stage • For the designer (WSP Finland) that had modeled simpler reinforced concrete bridges previously; this bridge with its curved geometry, cable-stays, and composite structural steel and reinforced concrete structure, is significantly more complex than what they had experienced previously • For the contractor (Skanska) this project as well was the first bridge modeling, using Tekla Structures and made a strategic decision to use a model in the construction stage as much as possible, including 4D planning and modeling temporary structures • Due to the pioneering nature of the use of BIM on a highly sophisticated bridge, the main BIM software provider to the project, Tekla Corporation, is also involvedPicture: 9/22

  12. 12. Interoperability Information Exchange through File TransferPicture: 11/22
  13. 13. Model Synchronization Synchronization Procedures • Synchronization required not only a technological solution but also a management protocol, agreed to by all parties, that stated who was allowed to edit what and whenPicture: 12/ 2
  14. 14. BIM Use in the Construction Phase Visualization • The Crusell Bridge is not an extremely large project, but has an interesting design and makes excellent use of BIM for a number of construction purposes • The 3D model of the project helps different parties to better understand the concept and especially the details of the design, forming a common mental picture and understanding far more quickly and effectively than with traditional drawingsPicture: BIM HandBook 13/22
  15. 15. BIM Use in the Construction Phase Design and Planning of Temporary Structures • The site team decided to thoroughly model all the missing temporary structures, including formwork shoring towers and the site tower crane on its tracks, directly in the design building model maintained onsite • This provided a better understanding of the structures, enabled identification of numerous collisions (clashes), extraction of accurate quantities, incorporation of these works into construction schedules, and visualization of their sequencing during 4D planningPicture: 14/ 2
  16. 16. BIM Use in the Construction Phase Clash Detection • Clash detection was done not only at the end of the design phase between steel and concrete parts, but also in the construction phase, incorporating additional systems and the temporary structures and formwork • Many clashes in the bridge structure that might only have arisen during construction were prevented • This BIM functionality save a large amount of money and prevent many problems Example of a clash detected between a cable anchor and formwork ties and its resolutionPicture: BIM HandBook 15/22
  17. 17. BIM Use in the Construction Phase Construction Planning and 4D • The 4D video animations of the schedule were done at the resolution of a single day • Thus the team could generate daily visualizations of the project, which enabled assessment whether the decisions made during the reverse phase scheduling stage of the Last Planner System™ (LPS) meetings were realistic in terms of their use of space • The animations also gave everybody a better understanding of which works they were agreeing to executePicture: BIM HandBook 16/22
  18. 18. BIM Use in the Construction Phase Fabrication and Installation of Structural Steel Components • Ruukki reviewed and edited the components in the model as needed to suit their fabrication constraints, and then sent the updated model back to the structural designers at WSP and to Skanska for approval • WSP then edited the structural steel components in its own model, incorporating Ruukki’s comments, and updated the server model for all other participantsPicture: 17/22
  19. 19. BIM Use in the Construction Phase Rebar Detailing, Fabrication, and Installation • Modeling the bridge reinforcement turn out to be more difficult than was anticipated • Bridges of this type (cable stayed) have a high density of reinforcement and complex deck and abutment shapes, which makes the modeling more difficult and time consuming than for simpler structures • Tekla Structures provides rebar material takeoffs in ASCII, EXCEL, and other file formatsPicture: BIM HandBook 18/22
  20. 20. BIM Use in the Construction Phase Laser Scanning • Skanska employ a surveyor onsite whose task was mainly to control the quality of the work and to assist the trade contractors with positioning • Skanska purchase a machine named Trimble® VX™ Spatial Station for use onsite to capture coordinates, take images, and combine themPicture: BIM HandBook 19/22
  21. 21. BIM Use in the Construction Phase BIM Suport for Last Planner System™ • Skanska had used the Last Planner System™ (LPS) in their projects for three years before the Crusell Bridge project, and have their own specialists who train site crews to use it • LPS has two main focuses: 1. Reliable short-term planning, 2. Creation and development of a social system onsite.Picture: & 20/22
  22. 22. BIM Lessons Learned A Building Model Supports a Wide Variety of Information, Uses of BIM in the Construction Stage • Plan using BIM and LPS from the very beginning of the project • Use the model to complement construction management techniques • Use the model synchronization feature to achieve fast information exchanges • Model temporary structures gives a better understanding • Import laser scanning point clouds into the model to check locations and work quality is highly effective • Use the model for visualization during LPS planning meeting to improve understanding of the product and the process • Involve project partners from outside the site as well as site teams • Ensure participants are commit to upgrade their software tools simultaneouslySource: BIM HandBook 21/22
  23. 23. Summary A Building Model Supports a Wide Variety of Information, Uses of BIM in the Construction Stage • The case clearly illustrates how BIM can be used in a bridge project • The teams’ willingness and openness to using BIM and new management methods (LPS) gave all of the parties the opportunity to experience and learn from their own failures as well as from their successesPicture: 22/22
