There are many kinds of scaffold systems corresponding to the structural shape and constructional condition. The design of the scaffold has been done under the safety standard by Ministry of Health, Labor and Welfare (2010) and Temporary Works Forum (2014) as well as the designer ’s knowledge. These standards specify the performance and safety requirements of the scaffold and introduce the general structural design methods of scaffoldings. In the example application, Figure 1 shows the hanging scaffold which is constructed to maintain the pipelines racked on the frames. Many kinds of materials are required to construct the hanging scaffold as shown in Figure 1. In designing the scaffold, the positions, the size and the quantities of all materials must be calculated. The design and the planning of the scaffolding system are quite laborious. Especially, the quantity surveying and cost estimation of the scaffold materials such as jacks, transoms, ledgers, etc, have been laborious. Therefore, these works have been empirically done based on the total volume or the total surface area of the structure. The discrepancy between design and actual quantities of the scaffold materials occurred frequently and brought the incorrect supply, the incorrect schedule and the unsafe condition.  \nIn this paper, the automatic design and drawing methods of scaffold were proposed. The method was presented for the sample hanging scaffold and the applicability for other scaffold system was also presented.  \nFigure 1. Example of hanging scaffold.  \n2 DESIGN PROCEDURE  \n2.1 System Environment  \nThe system is composed of the web server, the file server and the client computer or PDA. The web and the file servers can be placed on the clouding system. The material quantity surveying and cost estimation will be done outside the office and these data will be stored on the storage inside the office for the later use.  \n2.2 Quantity Surveying Method  \nThe quantity surveying method is represented using the example of the hanging scaffold shown in  \nFigure 1. The calculation system is running on the web with PHP program (Cowburn 2018) .  \n2.2.1 Web data input  \nFigure 2 shows the web input page. Firstly, the user should input the geometric conditions of the constructing structure such as the size of pipeline racks. Rack length and rack width are 40m and 10m, respectively. The column distance is 8m. The setting position is 0m. Then, the scaffold design conditions should be defined. The ledger distance is initially defined as 1.8m. The transom arrangement is selected (8th raw in Figure 2) . In this example, 4 transoms are arranged between rack column. The longest steel pipe length is selecte","cbCaipPzvUrkvK68","https://ap.wps.com/l/cbCaipPzvUrkvK68","pdf",531363,"English","# Introduction\n# Design Procedure\n## System Environment\n## Quantity Surveying Method\n## Web data input\n## Origin of the coordinate system in the calculation","[{\"question\":\"How are 3D drawings generated automatically?\",\"answer\":\"After calculating and recording 3D material positions and quantities on a data server, AutoCAD drawings are produced automatically using VBA, based on the previously designed material positions.\"}]","DESIGN AND PLANNING OF SCAFFOLDING SYSTEM - Automatic design and drawing method | PDF",15]
