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 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.

Identifying critical factors that affect the application of information technology in construction management: A case study of China

The new mode for managing construction projects with information technology(IT)has attracted worldwide attention because it can help managers and workers perform tasks and bring potential benefits,such as high-quality products and accident-free production,effectively.However,the application of IT in site have not achieved expected results because it is faced with many constraints caused by internal factors from enterprises and projects and external factors from the government and environment.Although many relevant studies have discussed the constraints of implementing different IT and devices in the construction industry or site,few articles have specifically focused on identifying and analyzing the indicator system.In this work,we took China as the background,scientifically identified 23 influential factors that affect the implementation of IT in construction management through literature review and expert interviews.Subsequently,questionnaires were issued,and Delphi method was used to obtain empirical data that aimed at four different management fields.Then,an efficient and convenient method called DEMATEL was used to deal with these data.Afterward,the factors were divided into four categories,namely,core,diving,independent,and impact factors.Finally,the similarities and differences of the analysis results from the four fields were compared,and the key factors were identified.Results show that the cross-domain talent ability,concept and value cognition,and organization structure are core factors in all management fields that should be managed first along with the IT innovation ability in the enterprise.The formulation of technical standards and related device and training input are also critical in specific fields.Strategic planning plays a role in macro control and promotion.Data management and application,platform construction,solution,and collaboration have direct impacts on information management.The research results provide suggestions not only for the government to formulate effective policies for IT application and promotion in construction industry,but also for enterprises to take measures in improving management efficiency in the construction site and realizing its substantial benefits.

Comparative Study of Information Technology Use by Architects, Engineers and Contractors

The use of information technology （IT） in construction is expanding rapidly. More and more architecture, engineering, and construction companies are adopting new technologies in software design to help accelerate and accurately carry out their functions. Based on a research study carried out in Southern Nevada with a questionnaire survey of 54 construction-related firms, this study aims to compare the types and extent of IT use by architects, engineers, and contractors. It also explores the level of IT skills possessed by professionals working in the industry. The study found that architects mostly used design software whereas engineers and contractors used scheduling and estimating software. All of the respondents believed that IT helped to improve their work productivity. The majority of the respondents thought that IT is useful for Construction Management （CM） students： engineers and architects thought that CM students should take more scheduling and estimating software courses and contractors thought that they should take more scheduling and quantity take-off software courses.

Augmented Reality Applied to Building Assessment with Building Information Model Visualization

AR （augmented reality） is a technology that adds information to the real world adding virtual elements to its visualization in real time. AR used in AECO （architectural, engineering, construction and operations） can contribute in augmenting visualization during design, construction and operation of the buildings. This article presents a study that applies AR to building assessment with BIM （building information） model visualization. The use of AR on existing applications for smart phones and tablets is validated. AR proposed an adaptation of the method of POE （post-occupancy evaluation） subsidized. Traditional POE process model involves three phases： planning, conducting and applying. In order to incorporate AR, it is proposed a total restructuring of the planning phase, developing the research instruments in three steps： 3D modeling, model treatment and AR application development. It was observed that for POE studies, the 3D models are in large scale and need to be detailed for precise comparison. BIM models for facility management, representing building use situation, are of the highest level of detail. A balanced point between simplicity and representativeness was the solution adopted in this experiment for uploading and downloading performance issues. This article presents and discusses findings for the new proposition for the activity of research instruments development for the planning phase of POE with AR as well as initial tests with first results and difficulties faced.

An Empirical Study on Project Management Maturity in Human Resources

The assessment of the Project Management Maturity （PMM） level shows the company how good it is at managing projects. This measurement can be performed in different domains of expertise. In the article, the issue of PMM in the human resources （HR） area is examined. The discussion is based on a world-wide empirical research project conducted in more than 400 companies. The study was mostly focused on the machinery industry as there is a dearth of research on project management topics in this branch of the economy. Therefore, by investigating the PMM level in the HR area, a picture of the state of project management in the machinery industry will be created. For the purposes of comparison, a study was conducted on the construction （CONS） and information technology （IT） industries which, in contradistinction, are very well recognized in the scientific literature related to project management issues. This approach will help to better contextualize and understand the results from the machinery industry. The PMM level measurement was done using the author＇s model which assesses maturity on a scale of one to five, where one is the lowest and five, the highest level of maturity. The results of the study revealed that there were differences among the industries in PMM levels and between Polish and foreign companies.
