BUILDING Bull, is that the model can be used for both documentation and building management, creating a powerful interactive window between the physical model and the building information data sets. The door schedule contains information about ﬁre compartmentation, space designations, and functional use of the space. Arup established a direct link between the model and the master door schedule database by attaching the ofﬁcial door number designation in the master door schedule database to the unique identiﬁer tag in the structural model door component. This makes it possible to locate a door number in the external facilities management database and immediately view all information about the wall containing that door, as well as space compartmentation data and all asset and facility management information. This system is bidirectional—it works from the BIM model to the facilities management database and from the facilities management database to the BIM model. Future links will connect directly to facilities management asset management software. The ability of the Bentley products to use VBA to link to Excel spreadsheets and external databases proved extremely important in Arup’s facility management investigations. Currently, the Opera House Facilities Management Group is looking at designing an intranet system that will use the continually growing 3D building model as its backbone. All information held by the Opera House and generated by external consultants and subcontractors will be stored in a central server database. Opera House staff, external consultants, and contractors will be able to access this large composite set of building information. This system will also allow data mining that may reveal seasonal trends and permit earlier identiﬁcation of potential operational problems. With this BIM-based system, the Opera House guardians will be well positioned to modify the building to meet changing needs while preserving the unique characteristics that make it a national and world treasure. Thirty-four years after its completion, the Sydney Opera House remains a pioneer of innovation. Structural Integration Bentley’s Integrated Structural Model acts as a central repository for all of its structural engineering products Greg Corke AEC Magazine A few years back, Bentley had its sights set squarely on the civil engineering, plant design, and architecture sectors—structural engineering never really appeared on its radar. But at the tail end of 2005, this all changed with the acquisitions of RAM International and the STAAD line of software from netGuru. Overnight, Bentley had become a major player in the structural design and analysis software sector, but with some 20 odd products in its MANCHESTER HILTON The WSP Group’s Manchester Hilton is currently the tallest post-tension concrete residential building in the United Kingdom. It is a 49-story structure with 279 rooms for the hotel from levels four to 22, and 219 apartments from levels 25 to the roof. The tower is 155 meters high to the roof parapet and the feature blade structure extends a further 15 meters above the main roof, making the overall structure approximately 170 meters high. Post-tension concrete was selected for the slab design in order to minimize ﬂoor-to-ﬂoor height. It allowed a slab thickness of 225 millimeters in the hotel and 220 millimeters on the residential ﬂoors. Above level 23, the ﬂoor extends four meters beyond the north face of the main ﬂoor to accommodate different functional requirements for residential use. Both post-tension slab and in-situ concrete cantilevered beams extend from the main core walls to support the extended cantilevers. In addition, the column layout changed from the top level to the ground level. Walking columns are used as transferred structural systems for the two short edges of the building. Edge columns walk a distance of several meters in two directions at two different levels. The slab design allows for push-pull effects. The effective and accurate modeling of this tall, slender building provided a challenge to the design team. The ability of Bentley’s RAM and STAAD products to modify input data easily and produce adequate and sensible output permitted the team to make informed decision during various stages of the project. This was critical for late changes requiring rapid decisions. For example, the design of the 22-meter structural steel feature had to be modiﬁed at a late date to suit the lifting capacity of the tower crane. After installation, the blade generated unexpected wind noise effect. Engineers analyzed the dynamic behavior of individual elements — BE Magazine in the blade to develop a remedy.
