Crusell bridge, Finland

WSP Finland Oy

Designed by modeling
Crusell bridge is located in the Ruoholahti section of Helsinki, Finland. It is 175m long and 25m wide. The design was chosen through a competition. The bridge and all accompanying structures on the shore have been designed by modeling. The Tekla model contains all structures. All concrete structures were modeled including reinforcement. WSP Finland Oy, who was in charge of structural modeling, also supervised its design during the competition. Drawings for steel assemblies and concrete structures were produced directly from the model. Analysis for the bridge structures were mainly done by FEM calculation.

Model synchronization
The construction model was published on the WSP server. Its Web Viewer format was used already in the bidding phase and was thus available for construction planning and management. The original structural model of Pylon steel structures was also available during the whole project. Many changes were impelemented in the structure after competitive bidding as suggested by the contractor. During the final structural design phase, a shared model was being synchronized on a web server. Project parties sharing the model were designer, project owner, general contractor and subcontractors.

冰壶-2010上海世博会芬兰馆，中国
(Expo 2010 Finland Pavilion Kirnu, China)

Lemcon Ltd

可拆卸的设计思路
2010年上海世博会芬兰馆命名为“Kirnu”，意为芬兰人喜爱的冰壶运动，它的建筑设计由位于赫尔辛基的JKMM建筑设计所完成，并在2008年进行的芬兰馆方案评选中从104位入围作品中胜出，成为上海世博会上芬兰形象的代表作品，在建造过程中聘请Lemcon（中国）公司作为项目管理公司进行管理。芬兰馆占地约3000平方米，钢结构主体使用约750吨钢材，所有钢框架均由螺栓连接，因此可以被轻松拆卸；如果将来有需要的话，还可以再加楼层。冰壶的外表面覆盖着鳞片状材料，这些鳞片状材料由工业回收的纸和塑料的混合物制成。

使用BIM进行制作和建造管理
BIM是设计芬兰馆的主要思路。使用ArchiCAD软件设计的建筑模型通过IFC格式导入进Tekla Structures，所有钢结构杆件都在Tekla Structures中建模，Lemcon公司使用这个模型来控制现场安装。Tekla Structures Construction Management(建造管理模块)在现场是重要的工具，除了高效的结构设计、预拼装和建造管理之外，Tekla 3D建造信息模型还被用在项目的各种创新方式上：检查最大起吊重量、辅助装饰设计和使用重现技术在将来恢复重建。阅读更多的关于冰壶的信息

Kuokkala church, Finland

Ramboll Finland Oy

Challenge of wood and concrete
The Kuokkala church is located in Jyväskylä, central Finland. All of its structures were modeled with Tekla Structures. The church has a pile foundation and basement, and its first floor is cast-in-place concrete. Other structures are made of wood. Main frames are glue-laminated timber, and the upper chord has been stiffened using plywood. The lower chord was stiffened with steel bracing. The roof and external walls are covered with slates. There is a separate cast-in-place bell-tower 14m tall with a steel tower of 11m on top.

Wide use of BIM
BIM was used quite widely in this project. Because of using Tekla Structures, it was possible to design all, even the most complicated structures. Architectural design was based on 2D drawings and that caused some problems during modeling. All other project parties used modeling tools and the MEP model was combined to the Tekla model. During the engineering phase the Tekla model was transferred to the Staad.Pro analysis and design software.

New York Yankees Stadium, USA

Thornton Tomasetti

Fabrication by modeling
This project, big in scale and stature, is 1,325,000 square feet standing 7 stories made up of cast-in-place concrete, composite steel framing, composite metal deck, and a prestressed-precast seating bowl. It has long-span cantilevered tiered seating with upper levels that cantilever 50’ beyond the support columns for the main seating level. The re-interpretation of the signature Yankee frieze at the canopy is 1465 feet long. Tekla Structures was used by the design team to develop a model for use by the fabricator. Full BIM processing was done using NavisWorks and included models from the architect, engineer, mechanical and erection contractors. There were a total of 12,000 tons of structural steel and 45,000 cubic yards of concrete used to construct this project. The structure took 18 months to design and 32 months for the construction.

BIM was instrumental in early discovery of construction difficulties
Building information modeling was a driving factor for successful completion of design and construction of the New Yankees Stadium. Multiple components of BIMs were initiated by the design team and maintained through the completion of construction by Turner Construction Company and their trade contractors. Individual components of the total BIM were imported into a common format by Turner and then used during extensive design and construction coordination meetings. Thornton Tomasetti started modeling the steel and concrete structures during the design phase, and the Tekla model was then provided to structural steel contractor CANAM, who completed the model through shop drawings and fabrication, as well as continued to update the steel components of the model in Turner’s evolving Navisworks model. The 3D digital representation of the complex interactions of all trades was instrumental in discovering and solving many construction difficulties early, in an electronic model rather than in the field.

Non-Schengen Terminal, Finland

A-Insinöörit Suunnittelu Oy

Important extension to the main airport
An extension to the current international terminal, the new Non-Schengen terminal is located at the main Helsinki-Vantaa airport of Finland. The building includes waiting areas, luggage handling and sorting areas downstairs and security check points. The size of the building is 41,908m2 and its volume 261,750m3. The new terminal is connected to the current T2 terminal by a passenger bridge. The Non-Schengen terminal will open in its entirety before the end of year 2009.

All structures were modeled
BIM was used widely in this project. All structures were modeled with Tekla Structures including reinforcing bars, precast concrete elements, and cast-in-place structures. The model was shared between the project parties using IFC and 3D DWG formats. All machinery and luggage rails were modeled and transferred to Tekla Structures as a reference model. MEP was designed with MagiCAD. The combined model was utilized on site. Construction company Rakennusliike SIERAK Oy used the Tekla Structures Construction Management configuration to create the combined model. In addition, the Tekla Web Viewer was used in many phases of the project. The Tekla model size for the project is 75Mb (db1).

Solaris, USA

Structural Consultants, Inc.

20,000 steel beam penetrations for mechanical systems and a complex roof
Solaris is a mixed use project consisting of 6 stories of condominiums and 3 stories of retail and parking. In addition to 2 stories of restaurant and retail space, amenities include a bowling alley, 3 movie theaters, an enclosed pool and an interior shipping area large enough for truck and trailer combinations. The main structure wraps around a courtyard which will function as a central gathering location for the City of Vail. The courtyard includes an ice skating rink during winter months and a partial grass plaza in summer. Project square footage is approximately 480,000 square feet. The building foundation is a mat foundation. The stair and elevator cores are the main lateral load resisting elements. The first 3 levels are major load transfer areas where column loads are supported over 60' transfer girders to precast bearing walls. The building's super structure consists of a steel frame with composite concrete floors. Cutting edge features of the building design include the use of approximately 20,000 steel beam penetrations for the routing of mechanical systems and a complex roof structure that was fully modeled using Tekla Structures.

Model coordination throughout the project
The Solaris project should be the multi-material category winner because the many innovative ways that themodel was used brought the project to its full potential. Throughout the project, the structural model has been coordinated with the architectural Revit model. This process was fundamental in visualizing and solving the complex geometry of the roof and complicated load transfers through 6 floors of custom condominiums. Ownership of the model was transferred directly from the engineer to the steel detailer and the detailer detailed the model provided by the engineer resulting in time savings. In addition, the 3D geometry of the model was used successfully by the precast detailer and fabricator in understanding the complex steel and precast interfaces at the roof. Owner driven changes to the roof after the model was originally issued to the detailer were modeled by the engineer and the model was transferred back to the detailer resulting in additional time savings. Approximately 20,000 steel beam penetrations were coordinated for the mechanical systems. The model was used for shop drawing review. The roof model was issued as the controlling document for the project, plans were used to cut details´, and the model was used as part of the permit process by the City of Vail.

Vierumäki Resort & Congress Hotel, Finland

Pöyry Civil Oy

An overall service project based on modeling
The resort and congress hotel is located near the Sport Institute of Finland in Vierumäki. All of its structures were modeled with Tekla Structures. The size of the building is 18-200m2 and it will be finished during the spring 2010. The hotel includes 191 rooms, 6 restaurants, a 10-track bowling center, meeting rooms, a fitness center and a central square. The Vierumäki hotel is an overall service project of Pöyry where they deliver everything from architectural design to fabrication including the MEP design and consulting.

Combination model used to achieve quality in construction
BIM was used widely in this project. The architect modeled the hotel, collaborating with structural engineering through IFC-format data exchange between Tekla Structures and ArchiCAD. The MEP and electricity were modeled in MagiCAD, and that information was transferred to Tekla Structures in IFC and 3D DWG format. The combined model was then used to prevent clashes and to achieve better quality for the consruction.
