Research on Integration of BIM and MEP Monitoring Information
Tian Peilong, Li Zhe, Hu Zhenzhong, Zou Dong
2015, 7(1): 8-13.
[Abstract](1220) [FullText HTML] (511) [PDF 2447KB](13)
Abstract:
Management of machine, electric and plumbing (MEP) plays an important role during operation and maintenance management of a building. At present, building automation system (BAS) is the primary means of MEP management, but the monitoring information of BAS cannot be effectively shared or used by other systems. Data sharing within building lifecycle can be achieved by adopting building information modeling (BIM) technology while most BIM researches and applications for MEP focus on establishing a product model that contains a wealth of information to improve the management efficiency by information inquiries. Few researches in the integration of BIM and MEP monitoring information are reported. By studying the integrated approach of BIM and MEP monitoring information, an extended model of MEP monitoring information can be established based on BIM. The model can provide data to support the operation and maintenance management of MEP, maximizing the value of MEP monitoring information.

Liu Xinye
2015, 7(1): 53-59.
[Abstract](1175) [FullText HTML] (531) [PDF 3566KB](14)
Abstract:
Green building development has stepped into the "deep green" phase, which means that the so-called green building of new building materials and new technologies can neither meet the requirements of the market nor be in line with the national policies. More importantly, although the effectiveness of green building is usually considered at the operation phase, the design phase has always been the most crucial phase for the building to start with a good green foundation. The first key step for a green building is to work out good green building strategy in design and to use suitable building technologies. The article analyzes the important role of digital simulation technology in fine design. With its high reliability, low cost, short project life circle and flexibility, digital simulation technology has become a reliable tool for working out green building planning and predict the future results of all kinds of green technologies.
An Affordance-based Approach for Architectural Design Knowledge Modeling
Zhang Xiaoni
2015, 7(1): 60-64.
[Abstract](1093) [FullText HTML] (805) [PDF 1941KB](10)
Abstract:
In architectural design, designers often need to consider a variety of factors in the full life cycle. As these factors are usually hidden in the final results of the detailed design (architectural design drawings, etc.), it brings greater difficulties for the reuse of the architectural design knowledge. This paper presents a new concept "Affordance" based on the design methodology to solve the problem in modeling and application of the tacit design knowledge in architectural design. Firstly, this paper will explore the concept "Affordance"which is mainly used in the conceptual design at present and aplly to the detailed design stage of architectural design. Secondly, the information model based on Form-Behavior-Affordance (FBA) is built so that designers can model the whole hidden factors in the final results of the full life cycle. Thirdly, the Genetic-Programming technology is used to model the architectural knowledge. At last, a case of expanding a school building is used to present the feasibility of the method proposed in this article.

DEVELOPMENT OF GLOBAL INDUSTRY
Status of BIM Adoption and the BIM Experience of Cost Consultants in Australia
2015, 7(1): 103-110.
[Abstract](1104) [FullText HTML] (584) [PDF 1461KB](18)
Abstract:
There is anecdotal evidence that the adoption of building information modeling (BIM) is on the increase. However, the extent to which quantity surveyors (QS) (also referred to as cost consultants or cost engineers) are now using BIM features is not clear. The research reported in this paper was aimed at understanding the BIM experience of QS firms and cost consultants in Australia as well as to understand the progress they have made towards the use of BIM features. Data collection was a web-based survey of 180 QS firms with 40 responses and two in-depth interviews. Findings from the study show that BIM features are not readily used by QS firms owing to uncertainties concerning the integrity of three-dimensional (3D) models issued by designers, incomplete information in models, lack of knowledge concerning new business processes to drive the use of BIM use, lack of demand by clients, cost of implementing BIM features within the existing practice and learning time required to adopt BIM features. It appears that most of the firms have experience in computer aided take-off with twodimensional (2D) drawing in the project's front end tasks such as cost planning and bill of quantities. Most of them have little experience with automated extraction of quantities using 3D models. Only one experience the use of BIM features in contract administration duties. 3D computer-aided drawing (CAD) drawings are used only for visualization. In many BIM-based projects reported, cost consultants were not issued the 3D BIM developed by designers; instead, 2D drawings were issued to the QS for quantity take-off and cost estimation. In cases where automatic quantity extraction was performed using 3D models, there seems to be lack of clarity concerning the time savings achieved because the QS spent more time checking the accuracy of the 3D model prior to quantity extraction as well as sorting, and splitting take-off items. In the absence of trust in the integrity of 3D models, QS would prefer to use the manual on screen take-off using 2D drawings and 3D for visualization. Also, in the absence of industry-wide standard for classifying, and coding construction works, QS would have no incentive to switch to five-dimensional (5D) BIM estimating. Ways of increasing the use of BIM features by QS are highlighted.
Measuring BIM's Disruption: Understanding Value Networks of BIM/VDC
Wang Na
2015, 7(1): 111-115.
[Abstract](1151) [FullText HTML] (858) [PDF 1922KB](18)
Abstract:
This article helps us to fully understand the value network of BIM/VDC through measuring BIM's disruption. First of all, the author makes a comparison between two kinds of innovation with Clayton Christensen's ideas of "sustaining innovation" and "disruptive innovation." Secondly, he points out that disruptive innovations occur in two ways: "low-end' disruption and "new-market" disruption. And then, the value network theory explains why the author regards BIM as a disruptive innovation: BIM has introduced new capabilities, spawned new markets, attracted new customers, and will finally establish its new value network. In the end, the author points out that to successfully navigate BIM/VDC's future value network for the AEC industry, we should be open-minded, embrace the strange and ready to explore the opportunity for disruptive innovations.

Wang Na
2015, 7(1): 116-118.
[Abstract](1385) [FullText HTML] (792) [PDF 1330KB](19)
Abstract:
This article reviews the British government's BIM strategy since 1970s, namely construction operations building information exchange (COBie). Although the British government did not directly use this generic term BIM, the BIM technology is more and more widely used, such as London Heathrow's fifth terminal project. The British Government has taken a series of initiatives to promote BIM technology in the UK construction industry, such as the central government (Whitehall) pointed out the importance of BIM applications in government procurement, and all of the buildings and infrastructure, regardless of new or refurbished, should take advantage of BIM technology in the management; the National Institute of Building Sciences has also developed a BIM national libraries; a series of BIM-related education and training activities have been carried out. Therefore, the author concluded that the whole life cycle of BIM application will sooner or later be adopted by building owners, this should be no doubt.
