Contemporary Jewish Museum
Located
in downtown San Francisco the Contemporary Jewish Museum is the design of internationally-acclaimed architect, Daniel Libeskind. The intricate design of this building was modeled in 3D by an in-house detailing department using Tekla Structures. With the model clash problems were easily identifiable before the steel was onsite. The new building is an adaptive reuse of the historic Jessie Street Power Substation, which helped restore energy to San Francisco after the 1906 earthquake. The 63,000 SF facility will enable the Contemporary Jewish Museum to expand its mission of engaging audiences and artists in exploring contemporary perspectives on Jewish culture, history, art, and ideas through innovative exhibitions and educational programs.
The structural steel for this project was erected around the 100 year old historic Jessie Street Power Substation in downtown San Francisco. Existing walls and steel had to be surveyed and integrated into the Tekla Structures Model. Eccentric framing in the roof created overhangs and protrusions that required special shoring, custom designed to support the structural framing until final bolting and welding were completed.

Vista Grande High School Football Stands
Using Tekla Structures 13 profile and bolt creation capabilities enabled the creation of a variety of aluminum planks, seats, footboards, fencing materials, handrails, and bolts to match the customer's cross sections, weights, and material grades. With these aluminum profiles and bolts added to the catalog, reports for ordering were generated. The reports list all pieces and bolts from steel wide flanges and angles, to self drilling screws and rivets. This system cut down delivery costs by giving correct quantities of even the most minor pieces, which saved trips to the job site. Tekla Structures 13 allowed attachments of sub-assemblies to stringers to match the customer's preferred piece numbering. Stringers were linked to multi sheets (2S1 on multi sheet 2) while their sub-assemblies had to be copied (L900 on multi sheet 9) to maintain the correct numbers. Since there were several stringer assemblies that had minor differences, Tekla Structures cloning became very useful.
This model stands out in that almost every aspect of what Tekla offers a detailer is used in this model. The firm manipulated sub-assemblies, created aluminum profiles with proper weight, created bolts, used user connections and user details, and cloned several drawings. All the aluminum parts are matched to the actual pieces the fabricator uses everyday. These parts and also the bolts were all created with the idea of producing reports that would eliminate quantity errors made my manually counting. All of these ideas combined with a real life, accurate look in a rendered view.

Art Gallery of Alberta
This Project is an addition/renovation to the Art Gallery of Alberta in Edmonton. The 85,000 SF building will provide 24,000 SF of interior exhibition space, an expanded Education Centre, Restaurant, Gallery Shop, 150 seats Theatre, and 8,400 SF. of office and administration space. The exterior features patinated Zinc on the vertical surfaces, and a twisted ribbon of stainless Steel winding in and out of the 80’-0 high atrium, evoking thoughts of the Aurora Borealis (Northern Lights)
Traditional plans and specifications were able to define the scope of both the renovation work, and the construction of the 152’ long x 57’ wide x70’ high trussed box structure. The straight atrium steel and curved borealis support steel could only be defined using models from the Architect and Engineer. Extensive use of reference models (more than 100 received and 70 sent) allowed managing everything from changes, additions and revisions, to coordination with the exterior stainless steel panels, glazing, concrete, fire sprinkler pipes, and also to review any clashes and clearances.
The sub-assembly feature of Tekla Structures allowed breaking the large complicated assemblies down into simpler pieces for easier shop fabrication along with smaller, cleaner drawings. During shop fabrication and site erection, Total station surveying with the coordinates extracted from the model to check the critical location of brackets and holes for the borealis panels is being utilized. The TS project management tools are being used to track drawing dates, material information (PO numbers, due dates) and site erection progress. Erection sequences, lotting for delivery of trailers to site, crane positioning and lifting studies were all done within Tekla Structures.

Lucas Oil Stadium
Lucas Oil Stadium is a retractable roof multi purpose stadium located in the city of Indianapolis, Indiana. It will serve as the home ground for the Indiana Colts NFL team and have a maximum seating capacity of 70,000. The primary supports for the roof structure are two 'super frames' that span 750 feet with five transverse trusses that support low and high fixed roofs. The retractable roof consists of two panels which sit atop a series of mechanized carriers rolling on rails attached to the five transverse trusses. These two large panels which are each 160 x 600 ft meet at the peak of the stadium roof which runs North and South and open towards the East and West side lines. This is unique in North America as other retractable roofs open towards the ends of the stadium. Another unique feature is the 214 x 88 ft operable window wall located at the North end of the stadium, which provides additional natural light when closed and an 'outdoor' feel when opened. A complex catwalk system with multiple stairs threads itself through the transverse box trusses and below the roof structure to provide access to the various areas under and on top of the roof.
The 14,620 tons of complex structural steel was modeled in a single multi user model with the creation of 20,000 shop assembly and erection drawings and 37,000 fitting sheets. Concrete, precast walls, ducting and mechanical components for the retractable roof were also modeled for interface and interference check with other disciplines. Erection of all the steelwork has been successfully completed and the stadium is due to be opened August 2008.
