BIM semantic-enrichment for built heritage representation
In the built heritage context, BIM has shown difficulties in representing and managing the large and complex knowledge related to non-geometrical aspects of the heritage. Within this scope, this paper focuses on a domain-specific semantic-enrichment of BIM methodology, aimed at fulfilling semantic representation requirements of built heritage through Semantic Web technologies. To develop this semantic-enriched BIM approach, this research relies on the integration of a BIM environment with a knowledge base created through information ontologies. The result is knowledge base system - and a prototypal platform - that enhances semantic representation capabilities of BIM application to architectural heritage processes. It solves the issue of knowledge formalization in cultural heritage informative models, favouring a deeper comprehension and interpretation of all the building aspects. Its open structure allows future research to customize, scale and adapt the knowledge base different typologies of artefacts and heritage activities
Building information modelling project decision support framework
Building Information Modelling (BIM) is an information technology [IT] enabled approach to managing design data in the AEC/FM (Architecture, Engineering and Construction/ Facilities Management) industry. BIM enables improved interdisciplinary collaboration across distributed teams, intelligent documentation and information retrieval, greater consistency in building data, better conflict detection and enhanced facilities management. Despite the apparent benefits the adoption of BIM in practice has been slow. Workshops with industry focus groups were conducted to identify the industry needs, concerns and expectations from participants who had implemented BIM or were BIM “ready”. Factors inhibiting BIM adoption include lack of training, low business incentives, perception of lack of rewards, technological concerns, industry fragmentation related to uneven ICT adoption practices, contractual matters and resistance to changing current work practice. Successful BIM usage depends on collective adoption of BIM across the different disciplines and support by the client. The relationship of current work practices to future BIM scenarios was identified as an important strategy as the participants believed that BIM cannot be efficiently used with traditional practices and methods. The key to successful implementation is to explore the extent to which current work practices must change. Currently there is a perception that all work practices and processes must adopt and change for effective usage of BIM. It is acknowledged that new roles and responsibilities are emerging and that different parties will lead BIM on different projects. A contingency based approach to the problem of implementation was taken which relies upon integration of BIM project champion, procurement strategy, team capability analysis, commercial software availability/applicability and phase decision making and event analysis. Organizations need to understand: (a) their own work processes and requirements; (b) the range of BIM applications available in the market and their capabilities (c) the potential benefits of different BIM applications and their roles in different phases of the project lifecycle, and (d) collective supply chain adoption capabilities. A framework is proposed to support organizations selection of BIM usage strategies that meet their project requirements. Case studies are being conducted to develop the framework. The results of the preliminary design management case study is presented for contractor led BIM specific to the design and construct procurement strategy

Case study based approach to integration of sustainable design analysis, performance and building information modelling
This paper presents a case study based research of both the method and technology for integration of sustainable design analysis (SDA) and building information modelling (BIM) within smart built environments (SBE). Level 3 BIM federation and integration challenges are recognised and improvements suggested, including issues with combining geometry and managing attribute data. The research defines SDA as rapid and quantifiable analysis of diverse sustainable alternatives and ‘what if’ scenarios posed by a design team and client during the early stages of the project, where the benefits of correct decisions can significantly exceed the actual investment required. The SDA concept and BIM integration findings are explained through a convergence from conceptualisation to calculation stages, emphasising the importance of an iterative over a linear approach. The approach allowed for a multitude of “what if” scenarios to be analysed, leading to more informed sustainable solutions at the right stages of the project development, with a generally lower level of detail (LOD) and computational/modelling effort required. In addition, the final stage of Building Regulations Part L compliance calculations was reached with a lot greater level of certainty, in terms of its requirements. Finally, a strategy for long term performance monitoring and evaluation of the building design in terms of its environmental sustainability is presented, via integration between BIM and SBE (Smart Built Environment) technologies
Controlling Slab Flatness Automatically Using Laser Scanning and BIM
Developments of Terrestrial Laser Scanning (TLS) and Building Information Modeling (BIM) offer great opportunities to achieve a leap forward in the efficiency and completeness of dimensional control operations. This paper presents an approach that demonstrates the value of this integration for slab flatness control. The approach first employs the Scan-vs-BIM principle of [5] to segment TLS point clouds and match each point to the corresponding object in the BIM model. It then automatically applies the Straightedge technique to the TLS points associated with each floor slab, and concludes with regard to their compliance with given tolerances. The approach is tested using data from two real concrete slabs. Results validate the performance of the proposed system when compared with traditional measurements methods. A novel straightedge generation method is also proposed and demonstrated that enables more complete and homogeneous analysis of surface flatness for insignificant additional processing times
Conceptual design of fuzzy TOPSIS DSS for building information modeling (BIM)
Building Information Modeling (BIM) is playing a significant role in the development of Construction industry.Evaluation of BIM software selection is one of the key roles in successfully BIM adoption.Currently, there is limited study on BIM software selection. With a great potential for integration of MADM and the current Web 2.0
technology, the development of Web DSS based on TOPSIS is desired to solve this problem. In order to develop an effective DSS, the development of subsystem which is TOPSIS would be integrated with fuzzy element.The proposed of this integration is to deal with the vagueness of decision makers in order to evaluate and rating the software and attributes of BIM software selection.Inteads of use crips value, the decision maker will asked to weight and rating through linguistics.For example Very Low (VL), Low (L), Medium Low (ML), Medium (M), Medium High (MH), High (H) and Very High
(VH) will used for wighting asessement in BIM software selection.In order to demostrade this proposed DSS, a real construction project which UTHM Multipurpose hall will be deploy
Evaluating and identifying optimal BIM communication patterns within design and construction projects
The shift from paper based communication to exchange of electronic copies of documents and drawings has made project participants overloaded with information. Electronically exchanged information could be better supported through BIM and automation of routing information using workflow management technologies to improve information availability for decision making. However, it has been observed that BIM is currently being utilized as a number of disconnected models. The built-in intelligence in BIM allows automated updating and extraction of 2D drawings, documentation and other building information. Extracted documents create extra work to be communicated to project teams. Therefore more tasks and communications are created. Accordingly, this study identifies the impacts of BIM in project team communication. It also critically evaluates electronic communication patterns and people’s activities by data profiling to identify variables and project characteristics that have an impact on electronic communication level
Technology adoption in the BIM implementation for lean architectural practice
Justification for Research: the construction companies are facing barriers and challenges in BIM adoption as there is no clear guidance or best practice studies from which they can learn and build up their capacity for BIM use in order to increase productivity, efficiency, quality, and to attain competitive advantages in the global market and to achieve the targets in environmental sustainability.
Purpose: this paper aims to explain a comprehensive and systemic evaluation and assessment of the relevant BIM technologies as part of the BIM adoption and implementation to demonstrate how efficiency gains have been achieved towards a lean architectural practice.
Design/Methodology/Approach: The research is undertaken through a KTP (Knowledge transfer Partnership) project between the University of Salford and the John McCall Architects based in Liverpool, which is an SME (Small Medium Enterprise). The overall aim of KTP is to develop Lean Design Practice through the BIM adoption and implementation. The overall BIM implementation approach uses a socio-technical view in which it does not only consider the implementation of technology but also considers the socio-cultural environment that provides the context for its implementation. The technology adoption methodology within the BIM implementation approach is the action research oriented qualitative and quantitative research for discovery, comparison, and experimentation as the KTP project with JMA provides an environment for “learning by doing”
Findings: research has proved that BIM technology adoption should be undertaken with a bottom-up approach rather than top-down approach for successful change management and dealing with the resistance to change. As a result of the BIM technology adoption, efficiency gains are achieved through the piloting projects and the design process is improved through the elimination of wastes and value generation.
Originality/Value: successful BIM adoption needs an implementation strategy. However, at operational level, it is imperative that professional guidelines are required as part of the implementation strategy. This paper introduces a systematic approach for BIM technology adoption based on a case study implementation and it demonstrates a guideline at operational level for other SME companies of architectural practices
A technical review of BIM based cost estimating in UK quantity surveying practice, standards and tools
In light of recent technological advancements over the decades especially with Information Technology (IT), the ‘Building Information Modelling’ (BIM) is one of those advancements that have attracted significant attentions in UK construction industry. The UK government has acknowledged this trend and is joining the radical movement of adopting BIM by also making it a prerequisite for all those involved in public sector projects to have BIM ready by 2016. For Quantity Surveying (QS) profession, BIM presents huge challenges and opportunities, particularly in the area of cost estimating and quantity take-off. BIM offers the
capability to automatically generate quantity take-offs and measurement directly from a digital model of a
building, a process that traditionally is very time consuming for quantity surveyors. However, there is little evidence that BIM is systematically introduced in quantity surveying profession in UK largely due to majority of the BIM based cost estimating or take-off tools developed outside UK and adopted the different practice and rules in quantification.
In this paper, we examine the cost estimating practice and procedure in UK and the impact of the use of BIM. A
number of key challenges have been identified in term of information exchange, model quality and UK standards. It also reviews the existing BIM based cost estimating tools in the context of UK quantity surveying practice. A review methodology is developed to evaluate the ability of the existing BIM technology to support the UK QS practices. The methodology is applied to a number of leading BIM based estimating tools. The review assesses the technical and process approach of each tool and their ability of adapting to UK quantity surveying practice, particularly with the New Rules of Measurement (NRM), which is aimed to provide a holistic view of the technologies for the Quantity Surveying professions to make informed decisions
