Guidelines And Standards

The topic of Building Information Modelling (BIM) adoption by public organizations has become a central subject of research, and a significant amount of BIM documents, guidelines, and standards have been created to meet different organizational purposes. Compared to the building industry, the application of BIM tools for tunnel project management is lagging far behind. This paper proposes a methodology for integrating BIM tools for conventional tunnelling. A fundamental distinction is made between the tunnel internal architectural domain and the external structural domain. For the former, BIM methodology can be applied similarly to the building industry. For the latter, it is suggested that a BIM model be built according to the essential information generated during tunnelling excavation. The proposed methodology was put to test for an actual tunneling project. A routine was established where the supervisor on behalf of the owner was responsible for gathering and reporting essential data in tabular form. Via REVIT's Application Programming Interface (API), a code was developed so that a BIM model was built and updated automatic to data insertion. Ultimately, the final BIM model allows managing up-to-date qualitative and quantitative information visually. Thus, human understanding and interpretation are enhanced for future uses, such as maintenance, future renovations and project post-analysis.

Advancements in the computing realm have assisted the Architecture, Engineering, and Construction (AEC) industry to progress significantly by automating several design tasks and activities. Building Information Modelling (BIM) authoring tools have played a significant role in automating design tasks and reducing the efforts required by the designer in redundant, repetitive or production-oriented activities. This paper explores one such approach that, with the help of BIM authoring tool and its Application Programming Interface (API), reduces the efforts expended on formwork design for concrete structures. The paper utilises the concept of using BIM data as input to compute the quantity of formwork, and generate visualisations and schedule of formwork. The developed approach first takes data input from semantic BIM to the API environment for computation and design of formwork systems, which is then placed within the BIM model, to generate visualisation and prepare schedules. The research work utilises a structural concrete wall as an example to demonstrate the presented approach. The approach will be influential in streamlining the formwork design process in the BIM environment and reducing efforts required by the designer and the planning engineer. Since the formwork elements are generated as 3-Dimensional (3D) solids and smart BIM elements, the generated model of formwork can be used for resolving clashes, scheduling, and resource planning.

Building information modelling (BIM) is an information technology that has the ability to change the Architecture, Engineering, and Construction (AEC) industry in terms of enhanced communication and productivity. With the rise of BIM, panelized/off-site construction is gaining momentum within the home building industry. However, BIM has not yet been leveraged to its full capability with regard to construction prefabrication, due in part to the fact that BIM models are only roughly designed by architects and engineers. Furthermore, some construction-centric information, such as drywall and sheathing layouts, which require substantial manual modelling efforts, is not presented explicitly in the BIM model. In this regard, this research exploits a BIMbased automatic approach for designing and modelling drywall and sheathing layouts in order to facilitate building panel production in the prefabrication plant. The prototype system is built on the basis of Autodesk Revit through the use of Application Programming Interface (API). This system, taking architectural BIM information as the input, generates a detailed constructioncentric BIM model in accordance with construction specifications, and further enables users to obtain shop drawings and a thorough quantity take-off and cut list in order to manage the plant production. In addition, the prototype system is capable of optimizing drywall and sheathing layout design with the objective of minimizing material waste and joint length. A case study of a wood-framed residential building is adopted to demonstrate the developed prototype system.

Rule Based Approach

The kingpost was a vertical element that was used to support the structural strut in the deep excavation. The structural kingpost was commonly arranged by experienced engineers who used two-dimensional construction drawings. Thus, it was still time-consuming and error-prone. Currently, an available construction program has been developed to arrange the structural kingpost by identifying the clash problems in the 3D environment. However, they have a limitation for detecting the clash that was unable to visualize the concurrent clashes between kingpost and many underground structures. Then, the engineer cannot see all the clash incidents with each kingpost and move the kingpost to avoid the clashes successfully. Since the kingpost arrangement was still an inefficient practice that was limited in the visualization aspect, this research used engineering knowledge and advanced construction technology to detect and solve the clashes between kingposts and underground structures. The methodology used engineering knowledge of kingpost arrangement to develop the system modules by using a rule-based approach. Then, these modules were developed into the system by using visual programming of Building Information Modelling (BIM). To test the system, an underground structure from building construction was selected as a case study to apply the developed system. Finally, the finding of this study could overcome human judgment by providing less interaction in the kingpost arrangement and visualization improvement of clash occurrences in the 3D model.

PurposeThis study aims to develop a framework for optimizing the spatial requirements of the equipment in a construction site using a geographic information system (GIS).Design/methodology/approachAn ongoing construction project, an existing thermal powerplant in India, is considered to be the case study, and the corresponding construction activities were scheduled. The equipment spaces were defined for the scheduled activities in building information modelling (BIM), which was further imported to GIS to define the topology rules, validate and optimize the spatial requirements. The BIM simulates the indoor environment, which includes the actual structure being constructed, and the GIS helps in modelling the outdoor environment, which includes the existing structures, temporary facilitates, topography of the site, etc.; thus, this study incorporates the knowledge of BIM in a geospatial environment to obtain optimized equipment spaces for various activities.FindingsSpace in construction projects is to be considered as a resource as well as a constraint, which is to be modelled and planned according to the requirements. The integration of BIM and GIS for equipment space planning will enable precise identification of the errors in the equipment spaces defined and also result in fewer errors as possible. The integration has also eased the process of assigning the topology rules and validating the same, which otherwise is a tedious process.Originality/valueThe workspace for each activity will include the space of the equipment. But, in most of the previous works of workspace planning, only the labour space is considered, and the conflicts and congestions occurring due to the equipment were neglected. The planning of equipment spaces cannot be done based only on the indoor environment; it has to be carried out by considering the surroundings and topography of the site, which have not been researched extensively despite its importance.

Conventional Methods

PurposeThe contemporary practice of conventional maintenance for industrialised building system (IBS) constructions suffers from poor service delivery and defect repetition. A key problem impeding the widespread adoption of emerging technologies is the lack of competent contractors to support the effectiveness of the technology implemented in conventional methods and to ensure returns on investment. The shortcomings of conventional methods are assessed from the perspective of IBS buildings. This paper aims to identify the different system approach using Building Information Modelling (BIM) technology that is equipped with decision making processes.Design/methodology/approachThis paper describes the establishment of key problem areas, the elements involved in implementing good practice and the requirements for integrating maintenance management processes and information databases in the maintenance management system.FindingsConventional methods have little emphasis on defect diagnosis tools. They also enhance inadequate strategic decision-making in the analysis of information when attempting to improve the maintenance project outcomes for IBS construction. The characteristics identified in a case study of IBS buildings are presented and analysed.Originality/valueThe conclusions and recommendations drawn from the analysis of the IBS case study are discussed, synthesised and deliberated upon. The approach presented in this paper integrates various aspects of building information modelling technology to facilitate improved execution of IBS maintenance activities.

Microblogging sites have become important data sources for studying network dynamics and information transmission. Both areas of study, however, require accurate counts of indegree, or follower counts; unfortunately, collection of complete time series on follower counts can be limited by application programming interface constraints, system failures, or temporal constraints. In addition, there is almost always a time difference between the point at which follower counts are queried and the time a user posts a tweet. Here, we consider the use of three classes of simple, easily implemented methods for follower imputation: polynomial functions, splines, and generalized linear models. We evaluate the performance of each method via a case study of accounts from 236 health organizations during the 2014 Ebola outbreak. For accurate interpolation and extrapolation, we find that negative binomial regression, modeled separately for each account, using time as an interval variable, accurately recovers missing values while retaining narrow prediction intervals.

Purpose The purpose of this paper is to explore and rank the benefits and barriers (technological and non-technological) of using Building Information Modelling (BIM) in sustainable building design. It also employs the use of a design tool analysis of a case study using BIM compatible tools (Ecotect and Green Building Studio) to determine the environmental performance of a proposed multi-use building at Derby North. Design/methodology/approach The paper explores the benefits and barriers of using BIM through a literature review. Regression and factor analysis were used to rank these benefits and barriers. A questionnaire was distributed to a sample of 120 practitioners with 69 completing the survey. Finally, the paper employs the use of a design tool analysis of a case study using BIM-compatible tools (Ecotect and Green Building Studio) to determine the environmental performance of a proposed multi-use building at Derby North riverside. Findings The key findings of the statistical analysis indicated that professionals ranked the integrated project delivery as the most established benefit, while the lack of interoperability was ranked the greatest technological challenge. Only three of the attributes of non-technological challenges made statistically unique contributions, namely, training costs and software costs, client demand and potential legal issues. It was also discovered that BIM delivers information needed for environmental performance. In a forward-looking approach, the paper attempts to provide some recommendations that would encourage the continuous application of BIM in sustainable building design. Research limitations/implications This paper does not cover all features of BIM functionality, as the scope of BIM is very enormous and the resources of this research were limited. Practical implications The implication of the study is that it will assist in exploring and ranking the benefits and barriers (technological and non-technological) of using BIM while proffering recommendations for future use. This research will be of interest to industry practitioners and academic researchers with an interest in building information modelling. Originality/value This paper contributes with new outlooks aimed at syndicating sustainability with environmental performance and adds to the limited empirical studies on the benefits and barriers of the application of BIM.

This study aimed to develop a microsimulation model for optimizing toll plaza operations in relation to operational cost and level of service for users. A well-calibrated and validated simulation model was developed in PTV Vissim, and several scenarios were simulated to test their efficacy at improving toll plaza operations. Data collected included classified entry traffic volume at the toll plaza, service time for different payment categories, percentage of lane utilization, and travel time while crossing the toll plaza. For modeling lane selection for vehicles, the PTV Vissim component object model application programming interface—which enables dynamic route choice—was used. From the results it was observed that the simulation model accurately represented the current operations at the toll plaza. Scenarios, such as implementing a number plate recognition technology and segregating lanes for different vehicle types to improve the level of service, were evaluated with the simulation model.
