Most construction tacit knowledge collected from past projects is not effectively utilized by construction practitioners to keep similar mistakes from recurring. ?Ignorance of acquired knowledge and misunderstanding of accepted knowledge? are two major causes of the reoccurrence of similar construction failures. Historically paper-based documents, illustrated with drawings and photos, have been used to describe lessons learned on construction sites. However, industry practitioners involved in modern construction projects often find it difficult to figure out knowledge of the past by reading paper-based documents. Many construction practitioners strongly agree that if construction failures were documented more effectively, repetitive incidences could be reduced. Humans gain 83% of their knowledge from visual observation. Although text is a more advanced method of expressing abstract knowledge, visual expression facilitates the formation of rich mental models of tacit knowledge. Combining emerging multimedia technologies such as video recordings, voice recognition, location identification, and mobile computing together may help identify an unprecedented way of collecting and disseminating tacit knowledge on construction sites.The objective is to discover if the combination of multimedia technologies could be applied to improving construction tacit knowledge management. The methodology involves identifying 1) available multimedia technologies that could be utilized on construction sites for knowledge acquisition, 2) merits of multimedia recordings in describing lessons learned on construction sites, 3) construction activities that can be described by multimedia recordings, and 4) methods to speed up the process of locating the knowledge needed among numerous multimedia recordings. The project also integrates multimedia recordings with Building Information Models.The intellectual merit of the proposed project relates to discovering the possibility of integrating emerging multimedia technologies and lessons learned on construction sites. The proposed project also provides an opportunity to monitor how younger engineers use multimedia technologies to gain new knowledge. While the proposed project will contribute to scientific understanding, it will also promote broader impacts especially related to teaching construction methods and safety procedures. The multimedia-based knowledge model will provide a semantically rich environment where users can learn lessons gathered from the previous construction projects.

大多数从以往项目中收集的施工隐性知识没有被施工人员有效地利用，以防止类似的错误再次发生。？对所学知识的无知和对已有知识的误解？是导致类似施工事故再次发生的两个主要原因。历史上，以纸张为基础的文件，配以图画和照片，被用来描述在建筑工地学到的教训。然而，参与现代建筑项目的行业从业者往往发现，通过阅读纸质文件很难了解过去的知识。许多建筑从业者强烈同意，如果更有效地记录施工失败，重复事件可以减少。人类83%的知识来自视觉观察。虽然文本是一种更高级的表达抽象知识的方法，但视觉表达有助于形成丰富的隐性知识心智模型。结合新兴的多媒体技术，如录像、语音识别、位置识别和移动计算，可能有助于确定一种在建筑工地收集和传播隐性知识的前所未有的方式。目的是探索多媒体技术的结合是否可以应用于改善建筑隐性知识管理。该方法包括确定1)可用于建筑工地获取知识的可用多媒体技术，2)多媒体记录在描述建筑工地的经验教训方面的优点，3)可以通过多媒体记录描述的建筑活动，以及4)加快在众多多媒体记录中查找所需知识的过程的方法。该项目还将多媒体记录与建筑信息模型集成在一起。建议项目的智力价值在于发现整合新兴多媒体技术和建筑工地经验教训的可能性。拟议中的项目还提供了一个机会，监测年轻工程师如何使用多媒体技术来获取新知识。虽然拟议的项目将有助于科学理解，但它也将促进更广泛的影响，特别是与教学施工方法和安全程序有关的影响。基于多媒体的知识模型将提供语义丰富的环境，用户可以在其中学习从以前的构建项目中收集的经验教训。
