A Quantitative Study of the Relationship between Project Performance and BIM Use on Commercial Construction Projects in the USA

This article reports the findings of a quantitative study on the relationship between various project performance outcomes and the use of Building Information Modeling (BIM), within the commercial construction industry. The literature review identified inconsistent results among prior qualitative and quantitative work concerning the relationships of key project performance measures and BIM use. Data on 13 variables from 93 completed construction projects were collected and examined through a causal comparative research design. Projects that used BIM (in design or construction) were not found to experience significant performance outcomes when controlling for the contribution of other independent variables and covariates at the 95% confidence level (CL). At the lower 90% CL, however, projects using BIM in construction experienced significantly higher levels of schedule growth than projects that did not use BIM in construction. Recommendations are made for training of construction management staff as a step to avoid unwanted schedule growth associated with BIM use during construction. This study is one of a very small group of rigorous quantitative analyses of BIM project performance outcomes conducted to date; additionally, it is the only study that has analyzed BIM in a multivariate context that controlled for the contribution of other project variables not directly related to BIM use.     

Extending BIM interoperability to preconstruction operations using geospatial analyses and semantic web services

Since the early 2000s, building information modeling (BIM) has been used through the entire project life cycle to facilitate effective project collaboration and integration of data to support project activities. Despite the successful applications of BIM in the design and construction stages, the use of BIM for preconstruction planning has not gained wide acceptance as in other project phases. The integration of BIM and geospatial analyses can offer substantial benefits to manage the planning process during the design and preconstruction stages. However, this integration suffers from a lack of interoperability across the geospatial and BIM domains. Semantic web technology is used in this study to convey meaning, which is interpretable by both construction project participants as well as BIM and geographic information systems (GIS) applications processing the transferred data. To achieve this, we first translate building's elements and GIS data into a semantic web data format. Then we use a set of standardized ontologies for construction operations to integrate and query the heterogeneous spatial and temporal data. Finally, we use a query language to access and acquire the data in semantic web format. Through two scenario examples, the potential usefulness of the proposed methodology is validated.     

The project benefits of Building Information Modelling (BIM)

Theoretical developments in Building Information Modelling (BIM) suggest that not only is it useful for geometric modelling of a building's performance but also that it can assist in the management of construction projects. The purpose of this paper is to explore the extent to which the use of BIM has resulted in reported benefits on a cross-section of construction projects. This exploration is done by collecting secondary data from 35 construction projects that utilised BIM. A set of project success criteria were generated and content analysis was used to establish the extent to which each individual project met a criterion. The most frequently reported benefit related to the cost reduction and control through the project life cycle. Significant time savings were also reported. Negative benefits were mainly focused on the use of BIM software. Cost/benefit analysis, awareness raising and education and training are important activities to address the challenges of BIM usage.

Impact of organization size and project type on BIM adoption in the Chinese construction market

Building Information Modelling (BIM) is perceived as an effective tool for improving the delivery and coordination of construction projects. The Chinese construction sector has demonstrated significant interest in implementing the 3-dimensional modelling-based process. BIM adoption is influenced by several factors which can either be operational or strategic related. Factors which can have a significant impact include the size of the construction organization and the type of projects that the organization has to deliver (i.e. building vs infrastructure projects). This study aims to evaluate the effect of project type and size on BIM adoption in the Chinese market, via an adoption model which analyses factors impacting the adoption decision. The study examines 200 samples collected from the Chinese construction industry, split equally between infrastructure and building construction data groups, as well as SMEs and large organizations. The collected data are first analyzed by principal component analysis and then through a Structural Equation Modelling-based multiple group analysis. Results demonstrate that essential factors such as operational risks are considered by small organization, whereas large organizations focus on implementation challenges. Implementation benefits and challenges are significant on the adoption decision in infrastructure organizations, but not in building organizations. In addition, the study reveals that “technical support” is an important factor when it comes to BIM adoption among all types of organizations, regardless of the organization’s size and project type delivered.     

Component based engineering of a mobile BIM-based augmented reality system

Over the last decade, building information models (BIM) have become increasingly popular. Yet their use on construction sites where the digital materializes, is limited. A technology that can bridge the gap between the digital and the real world is augmented reality (AR). We analyze this gap and the AR potential and present how the component based software engineering method can be used to efficiently implement a BIM-based AR system for construction. An architecture of the software system is proposed and verified by a prototype which was tested in a real construction project. We found out that the use of AR can significantly narrow the semantic gap between the digital model and the real world; that components for creating a BIM-based AR systems exist but currently do not scale well to large models; and that the use in AR applications creates additional requirements the for BIM models and tools, particularly related to the BIM's 4th dimension.

The advantages of information management through building information modelling

As building information modelling (BIM) is positioned by governments and construction professionals as a solution to the problems in the construction industry, research is needed into the benefits BIM actually confers. The focus here is on the effectiveness of BIM as a medium for communicating information within a construction team. A case study of an offsite precast concrete fabrication facility was conducted. At the time of the study, the facility was supplying precast units for four public sector projects, and using four information management systems: e-mail, a construction project extranet tool, an Enterprise Resource Planning system and a new BIM-based system. The flow of information through the four media was measured and visualized as the projects progressed. This quantitative measurement of information flow was combined with qualitative data from interviews with facility staff. It was found that the introduction of the BIM-based system diverted information flow through the building model and away from the extranet system. The use of e-mail was largely unaffected. BIM allowed considerably more accurate, on-time and appropriate exchange of information. It is concluded it is possible to quantify some of the benefits of BIM to information management. This research paves the way for future research into the management of more construction project information linked more closely to building models.

BIM-based integrated approach for detailed construction scheduling under resource constraints

Building information modeling (BIM) has been recognized as an information technology with the potential to markedly change the Architecture, Engineering, and Construction (AEC) industry, and has drawn attention from numerous scholars within the construction domain. Despite the reported advancements pertaining to BIM in previous studies, the extended use of BIM has not yet reached its full potential. This paper thus presents a BIM-based integrated scheduling approach which facilitates the automatic generation of optimized activity-level construction schedules for building projects under resource constraints, by achieving an in-depth integration of BIM product models with work package information, process simulations, and optimization algorithms. A developed prototype system for panelized building construction as an add-on tool for Autodesk Revit is described. A case study is subsequently presented to demonstrate the methodology. Building on the existing body of research in this field, the key contribution of the proposed research is the in-depth integration of BIM product model with work package information, process simulations, and an optimization model, which provides solutions addressing the challenges of the existing practice with respect to detailed construction scheduling under resource constraints.
