Developing a Modular Advanced BIM Course in Construction Management

Due to the rapid adoption of Building Information Modeling (BIM) in the architecture, engineering and construction (AEC) industry, many construction management (CM) programs in the US have introduced BIM in their curriculum. Previous research has revealed that most of the BIM courses offered in CM programs have mainly focused on modeling skills as well as BIM applications in scheduling and estimating. While these topics appear to be important to apply BIM technology, students will not be able to fully understand the BIM process in a construction project without knowing the fundamental workflow of BIM. This paper presents a modular BIM course which was developed to help CM students better understand the BIM workflow and focuses on advanced uses of BIM in construction projects. The course contains three modules: BIM workflow, basic BIM applications, and advanced BIM applications. The BIM workflow module discusses how BIM is addressed in project delivery method, contract, the execution plan, and team building. The basic BIM applications module explains the typical BIM applications in coordination, scheduling, estimating, logistics, visualization, etc. The advanced BIM applications module demonstrates the latest technology advances in the AEC industry that utilizes BIM applications, including laser scanning, virtual reality, and mixed reality. The course objectives and assessment methods ensure that CM students’ understanding of BIM will be considerably improved from as a modeling tools or software program to an efficient process, and their insights into BIM will be significantly broadened beyond the existing 3D, 4D, and 5D applications. The highly positive course evaluation demonstrates the effectiveness of these approaches in meeting course objectives, delivering course materials, as well as raising students’ interest. This paper will serve as a case study of an advanced level BIM course in CM programs.

The construction of platfbnn can realize information query, statistics and analysis and utilization in laboratory, establish personalized experimental learning environment, and achieve the goal of laboratory omnibearing management.

The Contributions of Building Information Modelling to Sustainable Construction

Global concerns toward environmental issues have induced growing demand for new approaches in the construction because of its considerable impact on the environment and use of natural resources. Through using construction sustainability tools, methods and techniques, a greener design can be applied during various building phases. In this connection, it is argued that the analytical and integrated models applied by Building Information Modelling (BIM) may also facilitate this process to be performed more efficiently. BIM and construction sustainability are quite different initiatives, but both have received much attention in recent years in the architecture, engineering and construction (AEC) industry. A rigorous analysis of the interactions between them implies that a synergy exists which, if properly it is understood that can be helpful to reduce the environmental impacts of the AEC industry. A BIM-based design model can contribute to sustainability through its three main dimensions which are environmental, economic and social. In this paper, by reviewing the existing literature on BIM and construction sustainability and using a matrix to analyze construction sustainability dimensions and BIM functionalities a number of interactions have been discussed. It can be concluded that despite there are many improvements in implementation of BIM in environmental and economic aspects of sustainability, its potential impact on social dimension has not been explicitly explored hence further studies need to be undertaken in this area.

智能建管平台下工程总承包项目信息共享激励研究

信息共享是提高工程总承包(engineering-procurement-construction,EPC)项目管理效率的关键因素之一,而以建筑信息模型(BIM)技术为基础,结合云计算、人工智能、物联网等技术,在项目全生命周期内对项目成本、进度、质量、安全等多方面进行有效的数字化管控的智能建管平台的应用可以有效改善EPC项目中信息不对称现象。但是工程实践中存在总承包商信息共享积极性不高的问题。针对这一问题,以业主方主导构建的智能建管平台为特定情境,运用演化博弈理论构建业主方和总承包商之间的博弈模型,分析双方在信息共享激励过程中的策略选择并进行仿真研究,以探讨不同参数对总承包商信息共享行为的影响,以及影响双方策略选择的关键因素。结果发现:业主方的额外收益越大、激励成本越低,其更倾向于采取激励策略;总承包商积极信息共享的潜在收益越大、消极信息共享的机会收益越小,其更倾向于采取积极信息共享策略;总承包商的智能建管平台应用成熟度和对总承包商的补贴对双方的策略都有显著影响。基于此,提出业主方应从物质激励和声誉激励相结合、基于智能建管平台应用的不同时期及时调整激励策略和辅以适当惩罚机制3个维度来制定激励策略,以促进总承包商积极共享信息。
