The unique architecture buildings in the worlds

In the worlds, there are various building with unique architecture concept require advance design and construction skills. Belows are some typical famous buildings in the worlds

1. Centre Pompidou Metz - France 

Centre Pompidou-Metz is the first decentralisation of a national cultural establishment in France. It was developed in collaboration with the great urban community - Communauté d’Agglomération de Metz Métropole. It is a public establishment for cultural cooperation whose founding members are the French State, the Centre Pompidou, the Lorraine Region, the Communauté d'Agglomération de Metz Métropole and the City of Metz.

The Centre Pompidou-Metz is an art centre dedicated to modern and contemporary art. Its cultural project comprises temporary exhibitions as well as live performances, films and talks within its spaces. Ongoing workshops for kids and teens provide insight into artistic movements and highlight the potential for creativity.

2. Soho Galaxy - Beijing, China

Galaxy Soho, Beijing by Zaha Hadid Architects has been shortlisted for this year’s Lubetkin Prize by the Royal Institute of British Architects. Named in honour of Berthold Lubetkin who established the influential Tecton Group in London during the 1930’s, the Lubetkin Prize is awarded to the architect of the year’s best RIBA International Award winning building.

3. Kunsthaus Graz Museum - Australia 

The Kunsthaus Graz, Grazer Kunsthaus, or Graz Art Museum was built as part of the European Capital of Culture celebrations in 2003 and has since become an architectural landmark in Graz, Austria. Its exhibition program specializes in contemporary art of the last four decades.
Its unusual form differs radically from conventional exhibition contexts, many of which maintain the traditions of the modernist "White Cube". The team of architects used an innovative stylistic idiom, known as blob architecture within the historical ambiance of the Murvorstadt. Thus, the gigantic building affectionately called the "Friendly Alien" by its creators Colin Fournier as the Partner-in-Charge together with Peter Cook, in form and material, stands out consciously against the surrounding baroque roof landscape with its red clay roofing tiles but nevertheless integrates the façade of the 1847 iron house. It has an organic shape with a skin made of iridescent blue acrylic panels.

4. Marriott Hotel - Hanoi, Vietnam

This is a 450-room convention center hotel with two convention banquet halls, three restaurants, an executive lounge, a spa and fitness center with indoor swimming pool and parking.
The main idea was to place the building at the edge of a man-made lake, part of the National Convention Center campus, and to recall the coastline of Vietnam. To achieve this, the edge of the lake was modified and expanded to conform to the edge of our building. The building wraps around an elevated central courtyard, embracing the visitors as they approach the main entrance to the hotel. The Convention Center activities (boardrooms) are located under the entry courtyard and are accessed at a lower level entrance. The Convention facilities are directly connected to the restaurants located at the edge of the lake.

5. The Cologne Central Mosque (DITIB-Zentralmoschee Köln) - Germany 

The Cologne Central Mosque with 48,000sqf area, is a building commissioned by German Muslims of the Organization DITIB for a large, representative Zentralmoschee in Cologne, Germany. After some controversy, the project won the approval of Cologne's city council.

The mosque is designed in Ottoman architectural style, with glass walls, two minarets and a dome. The mosque is proposed to have a bazaar as well as other secular areas intended for interfaith interactions. As the mosque will be one of Europe's biggest, it has been criticized for its size, particularly the height of the minarets

6. Wonderworks Pigeon Forge, USA

WonderWorks is an entertainment center focused on science exhibits with five locations in the United States. The company's slogan is "Let Your Imagination Run Wild".

Each WonderWorks location contains interactive, entertainment exhibits on the themes of space, physics, and math. Some locations also offer a dinner magic show. The exhibits are housed in a themed building designed by architect Michael Ussery to look as it were picked up by severe weather and dropped upside down on an existing building.All locations offer laser tag and a multi-story ropes course. The Myrtle Beach location has an outdoor ropes course and zip-line.

The company has locations in Orlando, Florida (March 1998), Pigeon Forge, Tennessee, Panama City Beach, Florida, Myrtle Beach, South Carolina, and Syracuse, New York (2012).The Palisades Climb Adventure opened in 2012 at Palisades Center Mall in West Nyack, New York. 

7. Guggenheim Museum Bilbao, Spain

Larger scaled installations by the contemporary artists and site-specific works of art are housed at the Guggenheim Museum Bilbao. This includes the 100-meter-long Snake, which is approximately 104 meter, by Richard Serra (Wikipedia Article) and displays of work and art by Basque artists. The museum houses a special selection of work that comes from the modern art collection from the Foundation itself.

The museum opened with a 300-piece overview from an artist of Cubism from the twentieth century of new media art, The Guggenheim Museums and the Art of This Century. The majority of the pieces here come from Guggenheim's permanent collection, as well as acquired paintings from Clyfford Still, Mark Rothko, and Willem de Kooning. This also includes newly commissioned works from Richard Serra, Jenny Holzer, Anselm Kiefer, and Francesco Clemente. 

Comparison benefit of using Revit and Archi CAD

As you know, BIM - Building Information Modeling open more great opportunities for software development, even with the long-historical development software like Revit and Archi CAD. They are both advanced and mature BIM software applications. Rather than discussing which one is best overall, you should investigate which one is the best fit for you or your company.
Bellows are some comparisons items between these softwares:

-          huge market capacity, common software standard for communication
-          widely supported (courses, books, tutorials, support) for architecture
-          be able to open with various type of files and widely documented.
-          Does not run on OSX, only partially multi-threaded, so needs fastest CPU, but does not take too much advantage from multiple CPU cores.
-          File size and scaleability issues.
-          Use of many families enlarges the project file considerably
-          almost fully multi-threaded, runs also on OSX, has a friendlier user interface (more visual - not dialog in dialog in dialog) and is oriented clearly towards architects.
-          It has very well developed support for IFC (easy to add custom PropertySets, by any user), good drafting & layout approach, decent rendering.
-          Very flexible and efficient parametric objects (through GDL scripting). GDL objects don't affect file size (only reference & attribute values are stored in a project).

-          custom objects require GDL scripting, which is a no-go for most users (who don't want to program)
-          many old workarounds are never fully solved
-          some extensions are never properly updated (most notably: stair maker), less-used API (C++ with limited documentation and examples).

BIM Casestudy: Shanghai Tower - China

Shanghai Tower owner champions BIM for design and construction of one of the world’s tallest (and greenest) buildings.

Project Summary 
Shanghai skyline is currently the second tallest building in the world and symbol of city’s financial district in China. The development is characterised by two landmark towers with two other iconic structures: Jinmao tower and Shanghai World Financial Center. The 121-storey transparent glass tower twist and taper as its rises, convey feeling of movement and growth.

The massive mixed use facility will include commercial, shopping mall, entertainment and cultural venues, luxury hotel and office building, which are obtain active and modern life Shanghai style. Shanghai Tower with 632-meters area will be the largest skyscraper in China.
The towering skyscraper comprises nine cylindrical buildings stacked on top of one another, all enclosed by a circular inner curtain wall and a triangular facade enveloping the entire structure. Each vertical neighborhood has its own atrium, featuring a public sky garden, together with cafes, restaurants, and retail space. The double-skinned facade creates a thermal buffer zone to minimize heat gain, and the spiraling nature of the outer facade maximizes day lighting and views while reducing wind loads and conserving construction materials. The facility can utilize its own wind farm and geothermal system to save energy. Rainwater recovery and gray water recycling systems also reduce water usage.
The Shanghai Tower is a scalable and massive project with various complex engineering structures and involve with many participants in other countries in the world. If project’s team try to work in a traditional ways, using traditional tools and delivery system, it would be difficult to carry out this project successfully. Therefore, Investor and Project Manager decide to integrate new technology process – Building Information Modeling into whole project life circle.

BIM application for Design Stage
The extended architectural and structural teams— with designers in offices around the world—shared their design models, enabling them to collaborate and contribute insights about the design in the context of the project. In the construction phase, the local project team, working from temporary offices near the construction site, routinely shared its models for project coordination and collaboration. This communication of design data resulted in a natural coordination of the project as it unfolded. In addition, the team used both Revit and Navisworks Manage software for formal clash detection.

Improving Design Communication 
The tower’s iconic twisting shape and dual-skinned facade were extremely difficult to convey using traditional 2D approaches, making model-based design vital for the project’s success. “BIM helped us visualize the tower in 3D and analyze the design for improved decision making,” says Xia. “For example, we used the Revit design model with the reflection analysis features of Ecotect software to analyze the glare from the tower throughout the city. This helped the design team optimize the outer curtain wall—even down to the position and angle of individual pieces of glass—to minimize light pollution.” “During design, BIM was indispensable for coordinating the major design disciplines and producing construction documentation,” reports Chen. Model-based visualizations will also aid in the construction process. “By visualizing a 3D virtual building, we can better monitor construction and gauge our progress against the schedule,” says Xiaoming Yu, deputy chief engineer and design supervision department manager for Shanghai Installation Engineering. “In fact, we require BIM deliverables from all the subcontractors and equipment suppliers. And during construction, it will be much easier for the workers to understand construction drawings that contain a combination of traditional views such as plans and sections, as well as 3D views and visualizations of complicated areas.”

Enhancing Coordination 
The project team used the Revit platform for early coordination of the major design disciplines. In the construction phase, the team is combining the Revit design models and the fabrication models in Navisworks for whole project coordination. “As construction proceeds, BIM is helping us coordinate the subcontractors’ fabrication models, leading to a better quality design and the avoidance of rework costs,” says Chen. “For example, the tower’s basement has already been built, and comprises five stories and 170,000 square meters of space,” says Gu. “During design development, we found only seven clashes. During construction, there were no clashes at all. It would be very difficult if not impossible to get results like that without BIM.” Conserving More Energy A central and attractive feature of the tower’s design is its transparent skin, which creates ventilated atriums that naturally conserve energy by moderating the atrium’s air temperature. “Green building and sustainable design were a common goal for the designers, as well as the property owner,” says Xia. “Model-based design was essential, as many aspects of our performance-based design were realized through simulations and analyses,” adds Peng. For example, during the design phase the project team used the Revit Architecture model for whole-building energy analysis, giving the designers quantitative feedback on building energy performance. “We shared this information with our owners and consultants to better inform our design decisions and trade-offs,” says Peng. Saving Building Materials The building shape itself will produce the largest energy savings in the form of an efficient, costeffective structural frame. “Using Revit Structure, we produced more than 20 design options before settling on a structural system of super-columns, with outrigger trusses supported by an inner concrete tower,” says Zhu. The team kept iterating the design, including the rotation angle of the building’s cam-shaped outer skin, to analyze the structure’s resistance to wind and seismic loads. The result was well worth the effort. Gensler estimates that the building uses 32 percent less material than a conventional tower— saving material costs as well as the energy required to manufacture more steel and concrete.

Improving Construction Efficiency 
Both the tower’s owner and its construction partners are requiring BIM models from all the project’s subcontractors to aid in construction coordination, planning, and digital fabrication. As an additional service, Autodesk Consulting also developed BIM submittal requirements for the owner—including the level of model detail required for coordination and construction planning—which were incorporated into requests for proposals for the Shanghai Tower. “By repurposing the design team’s digital building models for fabrication, and in turn using the subcontractors’ fabrication models for coordination, we are improving construction efficiency and reducing on-site rework and materials waste,” says Yu. “All the materials we use on-site are semifinished and ready for installation. The fabrication has already been done in the factories, which greatly improves our efficiency.”

Extending BIM to Lifecycle Management 
Even after construction is complete, BIM will still play a vital role for the Shanghai Tower. Shanghai Tower Construction & Development plans on using BIM for the facility’s ongoing operations and maintenance, as well as for emergency and property management. At the onset of its engagement, Autodesk Consulting created plans that detailed the as-built information and models that the owner will require for the tower’s lifecycle management. “We plan to extend the value of BIM to help our facility management staff plan efficiently and manage the building scientifically,” reports Gu. The Result With approximately 48 floors of the building’s core completed in 2011, the Shanghai Tower is on schedule for occupancy in 2014. “BIM helped our team produce a high-quality project and avoid many on-site changes, which would waste time, materials, and manpower,”

How do start BIM adoption?

The question “To BIM or not to BIM” is now transferring to the more imperiousness question “To BE or not to BE”. The speed of BIM adoption makes huge innovations for operation, cooperation method, infrastructure, employee recruitment and training activities. There are some big concepts and complex pieces of terminology to understand that leave people many asking: “Where do I start?”
Firstly and foremost, some tips for everybody to be able to already approach to BIM application:
- Understand the basic BIM concept and related terminology
- Have in-depth knowledge about realistic benefits of BIM that can bring to your organization and learn on BIM case studies on every scale.
- Consider your current business assets and information management to prepare necessary resources and create a process efficiently through digital techniques
- Looking for and prepare the necessary investments in software or required short-term / long-term training according to the efficiencies that BIM can bring you.
- Start with pilot project and learn as much as you can
For detailed, with each BIM object who will focus on one or more detailed benefit of BIM and they want to integrate BIM into their projects to advance value of deliverable products or eliminate risks for your projects, bellows are listing some specify important notes.
How do Investors/ Owners/ Clients start for BIM?
You are not working at construction field so it’s not easy to clarify and utilize designed product that you have to pay. If you’re procuring a built asset you shouldn’t have to put up with a poorly designed product that doesn’t support your business outcomes. As fact being, by traditional service, the designed products also don’t support for construction stage. By some BIM technologies now, you can avoid this by:
1. Supply information as much as you can about how your organization functions and operates. BIM can help you easy visualize comprehensive conceptual design at very early stage so they can create a built asset that will support you in getting there.
2. Create a set of “Employer Information Requirements” (EIR). This is important documentation to embrace all of information you need from your project team during the design to handover stage. Teams working without EIRs in place will struggle to ensure that the right information is issued at the right time to support decision making.
How do designers start for BIM?
1. Consider to link non-graphical information and schedules to specific graphical components by create information model
2. Consider common data environment (CDE) to communicate and share that model at different stages with your projects team.
3. You have to change from 2D to 3D environment for better spatial co-ordination. If you haven’t worked in 3D before, it can be very different to a 2D environment required time and
4. BIM for design is the category that’s likely to require the larger investment in terms of software authoring tools. You have to focus on the long terms efficiencies this can bring and establish a business case for your practice and consider about ROI data.
The biggest obstructiveness for BIM application is long established process with risk transfer, competitive tendering, and the focus on capital costs. So you can expect to be engaged on a more collaborative basis much earlier in the project process, some of solutions you can consider includes:
1. How you use information for estimate, schedule and construction, how you interchange information with others. Are they work efficiently on time and cost
2. You also consider software that allows users to open, view, interrogate information model in a common exchange data (CDE). Many software vendors offer tools that do this, that aren’t as expensive as the native authoring software itself.
3. Contractors are responsible in managing the design process have to set out systems and protocols in BEP (BIM Executive Plan) and a guideline for coordinate or Master Information Delivery Plan, hence sharing them with all parties at the outset. You have to manage the CDE and facilitate the process.
How to Consultants/ Project Managers start for BIM?
Depending on the type of consultancy or the specified tasks areas of project managers, you have to clarify BIM services/ technologies you can apply to project to get the highest benefits. Some advices for these objects are:
- Need to become familiar with the requirements of managing the BIM process (EIR, BEP, CDE…)
- Understand the process of linking cost data to 3D model integrated required information to generate estimates

Virtual Reality for BIM objects

The development of Building Information Modeling bring rapidly grow up for various technologies; Virtual Reality (VR) is one of them. VR is technology that BIM designed model can be visualized under the reality view by Virtual Reality (VR) glass technology, you can see on smartphone, gear VR or Oculus Rift. All of elements building like: Wall, interior, MEP… are embed real material, light into and set on scale 1:1 help investors and other peoples who don’t work as engineer still clarify technical design and help them easily decision making.
For detailed, Virtual Reality service brings so many benefits for BIM objects, including:
- For designer and Marketing/Sale: can express conceptual design for clients by the realistic image on the existing condition. It helps attract clients and shorten decision making process
- For contractor: As much as early decision making, improving constructability is an important aspect for time and cost saving in construction. We provide general contractors with a VR glasses with Virtual Mock‐ups(3D models) or mobile devices with 3D models/3D Shop drawings/3D PDFs for critical points complicated area. Then  contractors can easily preview the completed condition of certain rooms with 3D models or check the constructability by viewing 3D shop drawings with these devices. On the contrast of traditional way of thumbing through page by page ofdrawing set, 3D data is helping contractors, sub‐contractors to understand the area where they are about to work, precisely
Specifically, in healthcare, operating room’s layout of all equipment will be followed by surgeon’s specific operating procedures. Since the layout of quipment are dictating where MEP system such as gas pipes, ducts, wires, should be, as well, during installation. Therefore, inspecting the rooms with Virtual mock‐ups and making all related‐decisions in advance is very crucial and became very important process during construction. Early decision making by owners will help narrow down a number of change orders and it will save construction period. 

- Virtual Reality for Maintenance Control and Facility Management 
When construction is completed, it is the right time to compile VR‐panorama picture set. Especially for MEP rooms with all the equipment are installed, VR‐panorama pictures and manuals linked on pictures for each machine became very essential when machine was broken and needed instant inspection and repair. You don’t need any specific software to open the panorama data when it is saved in exe format. All you need is a pc or tablet pc to open the file by tapping with two fingers. Or VR‐panorama can be viewed HTML, Flash and QTVR format. 

Softwares in BIM

Softwares in BIM
Basically, a project life circle often passes into 8 stages.
0-1: project brief
2: Conceptual design
3-4: pre-construction
5: construction
6: Asbuilt  and handover

7: Operation
In the world, there are so many available softwares to use and everyday there are various start-up lauched in BIM software business. You can say BIM software is one of the most boomed industry in now. As you can see, Revit is also a small point in picture of using softwares in BIM process and often use from stage 2 to 4/5. Therefore, BIM is not Revit, Navisworks or any softwares... that is set of so many technologies and softwares can be used together

The differences between scan to BIM and point cloud to BIM

Scan to BIM is a process of using 3D laser to scan existing condition before construction or completed building to capture detailed information about elements in physical space. This process agrees on laser scan specification, include level of detailing and work scope. Scan to BIM service help:
- For survey stage: Ensure that have no barriers around building can be effected by the construction process
- For asbuilt stage: Support to do as-built documentation
Point cloud to BIM is a platform of technology and software to create 3D model with precise and accurate information from pointcloud for data usage. This is a latest technology used in the AEC industry to capture As-built conditions of a building by exporting point data on CAD or BIM software platforms like Revit.
Scan to BIM vs poin cloud to BIM

We have to create BIM model (3D model with detailed information that required for using) from pointcloud which scanned by laser scan. Hence, they can be used for coordination, prefabrication, estimation and scheduling.
Point cloud to BIM is the platform and scan to BIM is the process that has to be done in AS-BUILT condition.
Work Methodology:
Import the Scan file into Revit and set the co-ordinates as clients’ requirements.
All of building elements will be modeled in the listed deliverable scope of work
Model was timely submitted so as to keep a check on the project progress. Some of the elements which were completely not visible in the scans were develop using the photographs provided by the client.

BIM consultant: for the first time of 3D coordination integrating?

#1. General contract need a guideline for subcontractor in the first time integrating 3D BIM coordination into project.

Building Information Modeling is not new content but there are so many people don't throughout that what exactly it is? As fact being, when we provide 3D coordinate service to coordinate trades MEP, check clashes avoidance, resolve conflicts and export the shopdrawing for construction. Our product delivery is MEP trades shopdrawing documentation which was coordinated with other disciplines and resolved all of clashes. Although this can be directly utilized for construction, sub-contractor still re-exports to 2D CAD for construction as traditionally. It will be no problem if our shopdrawing can be edited by AutoCad. But it will be break lines when importing into Auto Cad, so architects have to use photoshop tool to re-draw each lines. This waste so many time and eliminate means of this service.

Revit drawing

#2. Prepare a meeting before handling service

3D coordinate service is to help all of project' s participants check out conflicts, errors, CLR of design drawing each of discipline (MEP, Architecture, Structure) and between of them. Therefore, all of involvers have to clarify responsible and process of performing and cooperation. Committing that all of required documentations must be sent and collected on time to ensure the contract’s schedule and everybody has to know what roles they are, why and how will they have to do that and what will they receive?

#3. A Common Data Environment (CDE)
The big letter make BIM different from traditional way is I – Information and CDE is solution for this. For traditionally, we communicate via email, Drive, Skype… information doesn’t update and need to look for so many files to get a file you want. Project participants don’t be connected together, not ensure transparency and clearances. CDE is where collected all of project’s information and have so many benefit, including:
- Archive all of information on Cloud so ensure absolutely security.
- Allow users search information as easily as Google
- Information can be updated but still saved the previous version. That allow users compare, realize and adjust easily all of works had happened
- Online file review: allow users review almost popular types of file in construction (doc, pdf, dwg…) that don’t have to set so many softwares into computer
- Coordinate, Review and stamp
Users can check anytime, anywhere within internet connection. Popular CDE platform that we can use is FTP, Dropbox, Google Drive… In short, CDE is the most important in BIM coordination. But in fact, there are so many people still hesitate to work on CDE, because of some reason can be talked in bellow:
- Internet platform isn’t enough strong to access and connect
- Be not easy and useful like Email, don’t understand its functions
- Fear to change communication behavior although it’s unsuitable now.

Navisworks and Revit for 3D BIM coordination

All of below contents oriented from opinions of experienced technicians in over the world.

Revit and Navisworks are built for each other, Autocad MEP 3D is a serious attempt at BIM, but is built onto a platform that wasn't intended for modeling.
Cut sheets and shop drawings remain a 2D Autocad production, which is one of the issues with incorperating BIM throught ALL trades.

Revit is more useful on the Engineering side and Navisworks is more useful at the construction manager level working with contractors developing specific installation drawings, aka shop drawings…

Revit does not do as the type of design and Navisworks is not used to create construction documents

Revit can hydraulically calculate a fire sprinkler system and generate a fabrication stocklist of that piping system and generate a cost report and handle warehouse inventory based on the stocklist, generate weld diagrams automatically for the fabricator, tag the shop drawing automatically so those fabricate pieces can be located in the shipment of piping and installed in the field. Revit allow users to do it but the system wasn't built to do this very quickly. It isn't a tool created primarily to look each item up, calculate material cost and installation cost, then add that amount to the "Cost" field for each item

The issue with Revit is that it is more for MEP engineering and design than Shop drawing production. While in the future it may indeed do those things so that everyone can use it seamlessly. Which brings me to my point that Revit is not a good tool at the construction manager level for coordination between trades and that Navisworks is much better suited as it can read files from each trade.

Construction managers try to force everyone to be "seamless" and use a program that cannot adequately do what we need it to do.  And the real reason I see them wanting it is because they want a smoother project and they see that utilizing 3D design in the coordination process is the way to go about it.  But they don't seem to see the difference between Revit and Navisworks.

Navisworks is not used to create construction documents. Rather to overlay various designs from individual contractors into one 3D model.  Naviswork is better than Revit reviewing their model and looking for interferences.

You are modeling HVAC and plumbing in Revit for a Mechanical contractor, while there are other models being created, .dwg format, for the different displines of the project. The GC is using Navisworks on the jobsite for 3d coordination and to run clash detection.

That is 3d coordination/clash detection with .dwg models and .rvt models is near impossible to do with just Revit and AutoCAD. The firms creating the .dwg models have to export to .ifc files for me to be able to manipulate them in Revit and run clash detection correctly but when importing .ifc files into Revit MEP the software kicks back 100s of errors causing the deletion and disconnect of may elements. Having Navisworks fort the overall clash detection so far seems to be the way to go.
All in all, different softwares, different file types, seems like anyway you go, you will lose information in translation which defeats the purpose of 3d models and coordination.

In many experiences, conduit in AutoCAD made them dislike conduit in Revit. However, as they continued to use Revit, they quickly learned new tricks for Revit conduit. Additionally since Revit is a model authoring program, all the other features about it make it a much better choice for general management of the project.

Revit is very useful and very much more than "just a design and engineering" software and Navisworks coordinate with Revit for 3D BIM coordination

For electrical contractors, pre-fab is different than it is for ductwork and piping. We currently don't do any pre-fab. I can understand the other comments regarding the differences between FAB software and engineering software. But for electrical, we can field bend conduit and certain types of cable tray, so we don't really need to be able to create a schedule of every fitting used in the project. For our purposes Revit is very useful and very much more than "just a design and engineering" software.
