U & Mi Urban Design Group uses BIM to help reduce working time, cost and investment
“By using Civil 3D in generation and analysis of topography, U & Mi has not only reduced the time required for analysis, but has consequently improved productivity. ”
— Seung-beom Gang, CEO, U & Mi Urban Design Group
Building technological skills as a specialized urban planning and design company
U & Mi Urban Design Group was founded in 2011 by experts in urban planning and design with the goal of creating a beautiful city. Its focus was on development and general planning as well as detailed planning and design such as site planning/design, urban design and district planning.
Performing tasks related to development and proposal for development planning, urban regeneration and urban specialization planning, U & Mi consists of two urban planning task force teams made up of experts with strong technological skills. Areas such as architecture and transportation/environment/ civil engineering (unit civil engineering) are carried out in cooperation with specialized companies. The company is currently engaged in tasks such as a Seoul maintenance plan (redevelopment, rebuilding, urban environment), a reorganization promotion plan(change), and district plan(reorganization) change in the public sector. As for the private sector, it is carrying a variety of projects forward such as housing development and district planning of tourism and leisure facilities.
“District planning is a plan of land and buildings, and an architectural plan is made once the location and use of the land and buildings are planned,” said Seung-beom Gang, CEO of U & Mi Urban Design Group. “U & Mi is currently using software for stereoscopic planning of land and buildings.”
Need for efficient spatial data analysis and compatibility Most projects and proposals in the field of urban planning/design are performed with all data computerized, using various files such as numerical maps, CAD, spatial data, images and documents. U & Mi has been using all kinds of software including not only design software for drawings, but also graphic software for proposals and Word processing for reports. In particular, various working files made by GIS and CAD software are used in projects and proposals. Spatial data files are called from GIS software by entering data or analyzing numerical figures, and the CAD software is used to create what is necessary for writing a report by working on drawings and diagrams based on the analyzed data. “There was a problem in this process because we couldn’t modify or analyze the GIS data file directly on CAD, and it was inconvenient since data referencing was not smooth,” said Gang.
“Accordingly, there’s an increasing demand for a GIS solution that offers an integrated management of land attributes and architectural drawings for schematization and analysis of urban planning attribute data.” To resolve this issue of inconvenience, reduce working time and secure compatibility of files, U & Mi reviewed the solutions that can actualize a consistent process of input, editing and analysis as well as visualization based on direct use of spatial data files. As a result, the company decided to impleme implement Infrastructure Design Suite Premium.
Generating and analyzing 3D topography with Civil 3D
U & Mi needed the topographic analysis data of the relevant region to analyze the status of the district system and establish the development plan in the process of performing the project. The company is using Civil 3D in establishing and analyzing topography based on a numerical map. The company has effectively and rapidly performed the tasks that had been dualized by reviewing civil engineering designs in making the plan for civil engineering and using Civil 3D in soil quantity analysis, syncline and slope analysis, and plan verification.
First, U & Mi extracted contour data from the numerical map equivalent to the zone, and used this data to establish the 3D topographic information of the district system. This was used to analyze the height, slope and direction based on 3D topography, and as a result, analytic data required for determining the status of the zone could be produced more quickly and effectively.
Along with the 2D and 3D analytic data, U & Mi automatically extracted the legends for each analysis as well as area tables to be used in the project. Moreover, the topography was drawn up with LandXML and used in building the 3D model for reviewing the zone.
Analyzing regional characteristics with with Map 3D and proposing the project
Previously, AutoCAD and the GIS software had been used simultaneously to analyze the CAD data as well as the data of existing facilities within the zone in the process of establishing the development plan. U & Mi has come to use Map 3D in analyzing spatial data as it has implemented Autodesk Infrastructure Design Suite, thereby reducing working time.
Spatial data shape files such as buildings in the zone could be analyzed in combination with DWG™ data within the Map 3D environment. Moreover, U & Mi verified and reviewed the attribute data of the shape files, and worked on thematic maps in which this data is shown in graphics. Also, the company calculated various thematic map data per building use, region, area, floor, structure and year, and used them as data for proposals. The company reduced working time, cost and investment by editing and analyzing CAD data and spatial data within a single environment.
Visualizing the 3D model with InfraWorks to review the development plan
InfraWorks is a solution that establishes a 3D model based on accurate coordinates, numerical figures and spatial data. Furthermore, it can integrate various data such as CAD, GIS, BIM data, image data and database, and make them three-dimensional. U & Mi used InfraWorks in analyzing and reviewing the district conditions and changes in the development plan.
First, the company integrated aerial photographs and shape data of the relevant region and formed the current context of the zone based on the LandXML data of topography drawn up by Civil 3D. Simple tasks such as using attribute data and entering numerical figures allowed U & Mi to convert 2D data such as shape data to 3D elements. By representing the 2D data with the 3D plan, the status and plan were actually compared and reviewed.
Visualizing the 3D model with InfraWorks to review the development plan
Furthermore, 3D thematic maps were produced based on analyses of topography and attribute data. Also, rights-to-light were analyzed according to date and time within the model, which also enabled analysis of rights-to-light of the newly planned building.
Finally, by applying various predefined animated actions, effective visualization output was produced quickly and easily. “There has recently been increasing emphasis on the consideration of environmental elements in urban planning,” said Gang. “By using InfraWorks, we can easily visualize tasks such as moving a building in the deliberation process, thus increasing usability in reviewing environmental elements such as direction and sunshine analysis.
Securing compatibility among work data
It had been previously difficult to carry out tasks such as entering and analyzing spatial data or schematizing using a single software program. However, the Infrastructure Design Suite line allowed U & Mi to secure compatibility among programs since it is organized in the form of a package in order to enhance compatibility among tasks or files. As a result, U & Mi effectively performed analysis and schematization through a smooth connection between products, and reviewed the applicability of the pilot project. “By using Civil 3D, we could take care of tasks that required multiple software programs such as drawing attribute analysis and schematization all at once,” explained Gang. “Thus, we could optimize hardware performance while also gaining benefits in managing the company.”
Securing data applicability with the integrated solution
Map 3D, Civil 3D, and InfraWorks included in Infrastructure Design Suite Premium and Ultimate allow users to conduct various analyses using spatial data files and create many kinds of proposal data by providing the function to generate visual data. Moreover, users can work on inserting various shapes, sizes and effects based on aerial photographs or screenshot image files using Raster Design, after which they can be reused as various forms of images to be included in reports. In addition, by using InfraWorks, users can easily and effectively create images or videos that are visually friendly and easy to understand.
Improving consistent work processes
By using Infrastructure Design Suite U & Mi was able to perform the tasks in urban planning with only 1 or 2 workers, where it had originally taken 2 or 3. High-quality outputs could be obtained as one worker takes care of the shaping and drawing for one day and visualization for another day.
“Easy editing and various uses of GIS spatial data also resulted in improving the quality of proposals by building 3D models based on spatial data, thereby producing effects such as increasing data compatibility and reducing working time,” said Gang.
Improving project quality and expanding the scope of business
Analyses using spatial data or reports and proposals are important in projects and proposals regarding urban planning/design, complex planning and district planning, and are contents that can be shown as outcomes.
U & Mi plans to resolve the inconvenience issues in data transfer and conversion between CAD and GIS software using Infrastructure Design Suite, and further enhance work efficiency through effective management of spatial data. Moreover, the company expects to produce more high-quality outcomes through integrated management of various data in reports and proposals. U & Mi will also use Infrastructure Design Suite in maintenance through 3D model analysis and visualization based on spatial data of urban planning.
U & Mi expects that this product can be proposed and used in most similar projects such as urban planning and design, and will continue to expand the scope of projects to civil engineering BIM such as complex planning and landscaping.
Promoting use of software to improve technological skills
Massive spatial data are used in the process of working on urban planning projects, but many results are represented by simple expressions. To improve this situation, U & Mi used the analyzed data in planning and will continue to expand the use of Infrastructure Design Suite in establishing better alternatives based on their plans.
In particular, products included in Infrastructure Design Suite can mutually connect data among themselves, thereby increasing data reliability. Moreover, the company plans to improve its performance in conducting projects by making various efforts, such as offering user training programs to enhance competency and efficiency in using the solutions. “It’s important to enhance the ability to use the software in order to increase efficiency and performance of the project,” said Gang. “We’re going to expand the application scope of Infrastructure Design Suite while also reinforcing the level of software application, and ultimately enhance the the technological and business competences of U & Mi.
