3D Browsing Solution for Windows System - Autodesk Navisworks The Windows client-side provides a 3D construction Fig. 3 Guanyinyan 3D BIM Construction System simulation scheme，simulation solution for 3D construction. Through photorealistic real-time Solution 3D simulation effect, designers and construction Data exchange - Autodesk BIM 360 operators can fully understand the structure and Autodesk BIM 360 provides a proprietary arrangement of the hydropower station in advance, engineering data transmission channel, by which and grasp the overall layout before the construction the design intents can be transmitted promptly, of each system. This allows them to better Fig. 2 Dam and Power House of Guanyinyan Hydropower effectively and accurately. Traditional design coordinate the construction progress and processes Station changes are performed by sending notices of design so as to ensure high quality and efficiency in the change to the construction sites via fax or Internet, construction of the hydropower station. Project Background and then notifying the other party through phone Users on the Client side can rotate, look around, Construction of a hydropower project is complex calls or emails, or sometimes by providing newly zoom in/out, section, measure and query the system engineering. It features include: large new modified drawings. This type of process leads attributes of the BIM models. These functions numbers of participants, deployment of an entire to a certain delay of information transmission. The can compensate for paper drawings, which lack complex project hub, extensive space and a tight construction drawings sent to the construction the ability of full display, and can also be used construction schedule. In particular, construction sites are for specific regions, i.e., there is a lack of to rapidly search for the required engineering of the main power house involves a large amount connection between different regions or professional information where the drawings are not clear. of concrete casting, coordination among different drawings), and construction operators need to look disciplines and complex working procedures... all up and check different drawings before construction, is one of the keys to controlling the construction thereby increasing the difficulty of construction. quality and progress of the entire hydropower Moreover, human error is not uncommon among station. field construction operators who have to deal with large numbers of drawings and notices of change. In the hydropower industry, 3D design technology It is difficult to update engineering information has been comprehensively applied to the design promptly and wrong versions of drawings are of construction documentation by KHIDI. The sometimes used. All this severely affects the progress Fig. 5 Picture of the Latest Field Construction power of 3D design has improved documentation and quality of construction.

3D BIM Construction System equipped with Autodesk BIM software plays an active role for all The 3D BIM Construction System parties involved in engineering construction. equipped with Autodesk BIM Using this system, designers can express their software takes huge advantage design intent accurately, promptly and effectively, of 3D design. The design intent allowing them to provide high-quality design results to the owners and construction and supervisory of engineers can be expressed parties. more explicitly, visually and quickly, and conflicts among As for construction and supervision parties, past engineering experience shows that during the different professionals in the field construction of a power station, ambiguous design construction greatly reduced. information and untimely transmission of design modifications result in construction operators — Liu zhipeng Fig. 11 Picture of the Latest Field Construction misunderstanding the design information. Frequent BIM Designer and Senior Engineer errors, omissions and risk at the construction PowerChina Kunming Engineering Implementation Results and Evaluation site likewise surface. All this has a major impact Corporation Limited 1) The engineering design results are on construction progress and quality. 3D BIM “informationized”. Traditional engineering design Construction System equipped with Autodesk results are delivered to the owners in the form BIM software, allows construction operators of paper drawings, documents, and the like. to view the 3D models on their mobile devices Summary Construction and supervision personnel also use and clearly understand the layout of equipment, By adopting a series of Autodesk software paper documents on site. The 3D BIM Construction pipelines, etc., as well as view the design change products (including the Revit series, Autodesk System equipped with Autodesk BIM software notices, and the parameters and attributes of each Navisworks series, Autodesk 360 series, etc.) and fundamentally changes the traditional approach. By equipment component. This greatly reduces errors, using state-of-the-art cloud service technology, the using handheld system terminals - mobile electronic omissions and risk, while decreasing rework and Guanyinyan 3D BIM Construction System carries devices such as iPad, iPhone, Surface, etc. - users waste. In all, the following objectives are met: out standardization, integration, networking such as owners, constructors, supervisors, field investment savings, on-time completion and quality and virtualization of engineering construction design representatives, etc. can construct with engineering. management. precision, rapidly search for drawings and relevant information, and check the status of equipment Owners using the 3D BIM Construction System Based on the successful implementation in the installations, etc. equipped with Autodesk BIM software can Guanyinyan Hydropower Station, this system effectively control key procedures in construction, can be promoted and used in other hydropower 2) The cloud server is updated in real time. get a prompt understanding of the engineering construction projects. Moreover, through further Traditionally, changes made to design documents construction progress and improve the level of research and development, the system can also be are performed by sending a notice of the change construction management. applied in the operation and maintenance phases by fax, etc. and then notifying the other party of hydropower stations, in order to realize the total by phone or email, resulting in a certain delay in lifecycle management of hydropower projects and the transmission of the information. The 3D BIM build modern digital hydropower stations. Construction System equipped with Autodesk BIM software fundamentally resolves this problem. The BIM Construction System is a dynamically updating system. Clients can connect to a wireless network, such as Wi-Fi, to obtain the latest real-time design results from the iCloud cloud server. The models and drawings of the equipment on site are always the latest versions. Fig. 12 Dynamic Update of 3D BIM Construction System
