Tekla Structures in Practice: Sutter Medical Center
BIM-based IPD is an innovative healthcare project of Sutter Medical Center (also known as SMCCV and Eden) situated in Castro Valley, USA. The center is scheduled to be delivered 30% faster than other comparable healthcare projects in California which requires implementation of lean construction principles and technologies like BIM.
During the project, the Integrated Project Delivery (IPD) team used to meet regularly to compare modeled building information. For example, in the detailed design coordination phase, the coordination process involved reviewing all the individual disciplinary models floor by floor.
All the firms involved in the project, used the solutions in which they have the best expertise. The models were being developed together so that the MEP engineer and detailer were working in sync on the same model and so are the architects and contractors. So that the building information in the models is reliable and the team can accurately extract automated quantity takeoffs whenever they are needed.
Tekla Structures is a tool that enables reinforced steel to be part of this process. Tekla structures give us the ability to quickly and accurately reveal and communicate conflicts with design, constructability issues and clashes with other trades. The ability to have experienced and successful people from different disciplines come together builds trust, develops innovation and brings to realization the value added to every project willing to focus on the customer’s expectations and goals.
BIM technology saves time and money
By creating customized wall layout drawings using Tekla Structures, the general contractor was able to see a 10% increase in productivity during wall and embed layout. For exterior skin, over 25% of the wall penetrations required for the precast system were moved or removed due to conflicts with congested rebar areas. These changes were accomplished without a schedule delay due to model coordination with the reinforcing bars using Tekla.
Sutter Medical Center Castro Valley is the first completed IPD and BIM project. Working in a collaborative environment utilizing lean construction principles and having powerful tools such as Tekla Structures promotes a successful project that is higher in quality and lower in cost."
Tekla structures software was utilized to the maximum, investing resources in the development of the electronic model approval interface and training the structural designers to use the interface. But it was worth as the investment paid tremendous dividends in terms of cost savings for all the stakeholders, and in terms of accuracy, interdisciplinary model coordination and on-time delivery.
Development extend to future projects
The Tekla model was very helpful with respect to the exterior skin coordination. It also helped them to identify constructability issues, gaps in design, and issues with skin trade interfaces. The modeling in Tekla has profoundly affected the future processes of our skin subs as well as our rebar subcontractor.
