應用三維空間套圖在科技廠房機電工程施工之研究

Abstract

近年來電子產業規模日趨龐大，且工程的時效性、複雜度及專業性的要求不斷增加。又原物料的上漲及同業競爭下，工程單價面臨嚴格的考驗，現今的工程施工僅能靠有效的管理才能創造獲利。機電系統由於其種類複雜、施工多樣與工期限制之關係，在施工階段常常因為缺乏事前完整之空間整合，以致施工程序紊亂造成變更設計及工期延宕，使整體工期與品質受到影響。 常見2D機電施工圖還是存在相當多的視覺死角，所以國外軟體廠商為改善此種情形，也積極開發3D製圖軟體，除製作各式機電常用的圖塊，也在學習便利性做指令上的精簡。所以本研究將探討應用3D製圖在機電工程施工整合之方式，經由專家訪談及工地調查，透過人力計算方式做比較，並以一實際之案例做驗證，進行機電系統人力及成本分析。在過去的觀念裡。機電業承包商常會以過去傳統人力社會的觀念，以前能做為什麼要多花費成本去製作3D施工圖，在獲利降低的情形下，就拒絕新產品的引入。 這就是為什麼隨著數位化科技時代的來臨，電腦化已普及深入各階層領域，但是3D製圖確只能存在設計單位或甲方，作初步的規劃及美觀的運用。確無法發揮對實際施工最大的功效，讓人甚感婉惜。

Recently, the scale of electronic-industry factories is getting larger. Also, the timeliness of completing projects, the complexity of projects, and the demands of related professional knowledge increase. Meanwhile, construction companies face stringent circumstances, due to rise of raw-materials and increasing of competition among same traders. Therefore, the resulting-profit for construction projects comes from effective management presently. Because of the restriction of diverse in species, complicated in construction, and limitation of constructing-time, the constructing quality and overall construction time of electromechanical systems are highly affected if lack of comprehensive spatial conformity complete in advance. There are many shortcomings of common used 2D drawing system in mechanical and electrical construction drawings as lack of ability for representing the complicated spatial relationship among various components. Advanced 3D drawing system has been energetically developed and applied in many fields nowadays. The aim of this work is to investigate and utilize 3D drawing system in 3D mapping integration of mechanical and electrical construction projects. A real electromechanical project is employed as studying case herein and required man-hours are compared between use of 2D and 3D systems. The simulated results reveal that 3D drawing system is feasible for complicated electromechanical systems in constructing level. Also, some constructing conflicts can be detect and solve in advance.
