Optimization of the information flow using BIM within the construction supply chain

根据各种研究，建筑业的生产率正在下降，而其他行业的生产率在四十年里翻了一番。此外，供应链中与信息和材料管理不善有关的浪费量约为30%。建筑信息模型（BIM）被宣传为解决这些问题的技术解决方案，但使用BIM成功解决这些问题的证据尚未得到证明。核心问题是其实施缺乏理论和实证基础。根本问题在于信息处理。虽然BIM提供了一个在不同软件之间交换数据的共享平台，但它是一个不完整的解决方案，没有解决工作流程和数据流管理的社会技术方面的问题。**本研究的主要目的是利用BIM或其他技术优化信息处理。具体目标是：(1)为设计过程中的数据产生和交换制定设计规则和相关的应用程序编程接口（API），以实现持续优化；(2)减少这一过程中的信息生产过剩，从制造中获得最佳实践。**这项研究的一个独创性方面是设计了产生和形式化新的实践知识的方法。本研究建立在信息技术和组织科学中开发的新方法的基础上，其中调查和干预之间的循环迭代带来了变化，并形式化了有关信息处理流程化的实践知识。**通过利用本研究的结果，利用BIM的潜力，将有助于提高加拿大建筑业以更有效的方式交付可持续建筑，提高生产力，同时减少施工过程中遇到的资源和材料浪费。目的是以更低的成本为加拿大人提供更好的建筑产品，同时使我们的行业更具竞争力。**********************************************

According to various studies, construction productivity is decreasing while productivity in the other industry has doubled in forty years. Moreover, the amount of waste in the supply chain related to poor management of information and material is around 30%. Building Information Modelling (BIM) was advertised as the technological solution to solve these problems, but proof of their successful resolution using BIM is yet to be demonstrated. The core issue is the lack of theoretical and empirical foundations to its implementation. The root problem is about information processing. While BIM is providing a shared platform to exchange data between different software, it is an incomplete solution, not addressing socio-technical aspects of workflow and dataflow management.**The main objective of this research is to optimize the information processing using BIM or other technologies. Specific objectives are: (1) to develop design rules and related Application Programming Interfaces (API) for data production and exchanges in the design process aiming at continuous optimization; (2) to reduce overproduction of information in this process, deriving best practices from manufacturing.**One original aspect of this research is the methods devised to generate and formalize new practice knowledge. This research builds on new approaches developed in Information Technology and Organisational Science in which a cycle of iterations between investigations and interventions bring changes and formalize practice knowledge regarding streamlining of the information processing. **By leveraging BIM potential using the results of this research, it will contribute to improve Canadian construction industry delivering sustainable buildings in a more efficient way, and increasing the productivity while reducing the amount of waste in resources and material encountered in the construction process. The aim is to offer a better building product at a lower cost to Canadians while making our industry more competitive. **********************************************
