Design And Implementation Of BIM System Based On5D Model

BIM (Building Information Modeling) is widely used in the construction field, involvingstages of building design, construction, sales, maintenance, etc…. The concept of5Dbuilding models is frequently mentioned in recent years.5D building models is addingconcept of time and cost based on the concept of3D. Combind with information of the5Dmodel, Costing software can provide better services for the cost calculation engineers.Meanwhile, it also broadens the scope of application of the accounting software. Costingsoftware is not only widely used in the bidding, budgeting stage, but also used in theconstruction and procurement phases. With using a comprehensive3D file formats andcombined with the embedded database, it helps each of the3D engineering model file tointegrate a large number of cost accounting information, which facilitate the constructionengineers and cost accounting division to control the contruction schedule and cost moreefficiently in each period of the projectThis article is introducing5D management software in BIM domain which is based onthe requirement of construction manager and budget analysts, by using Navisworks softwareas a platform and DWF file plus embedded database as the data format. It also describesSyncfusion WPF controls library and XslIO library, which make the user interface of thesoftware is much easier to use, and artistic, in the meantime achieves costs reduction by usingSyncfusion controls. In the design of framework, it doesn’t apply memory model layer whichis always be used in graphics software, but bind the interface layer to the DataTable directly.This solution will help to reduce developing workload tremendously. The article alsoprovides a detail introduction of the design for the application layer, the database and the APIwhich are the core of the5-dimensional construction management software.The final design and implementation of software is to meet the requirements of the user to take off the amount of2D and3D models automatically and manually. User can identifythe takeoff information which related to the2D and3D model by the color and transparency.The software also provides a viewpoint function for the mark of manual takeoff which canhelp users understand the purpose and point of the manual takeoff. If the design engineerchanges the original drawings, the software can automatically identify the changed takeoffwhich is very convenient for the users. Export to Excel file functions can help users togenerate data files for further processing.The actual testing data indicates that this application can meet the requirement ofbuilding project manager and cost estimating engineer by improving their work quality andwork efficiency and saving the cost of building project.BIM has a bright prospect. In the current era of design software become more maturesand income is increasingly stable, Product management, software, communication softwarebetween the various departments will become a new growth point of the BIM domain. Thisapplication can help project manager and cost estimating engineer finishing the work whichdesign application couldn’t accomplish, it is an indispensable part of building industry.
