Visualization And Simulation Approaches In Construction
As robotics and automation technologies are integrated in building construction processes, it is also necessary to visual-ize and simulate the construction work with the help of augmented reality. Model simulation and visualization can help project engineers to estimate construction schedule, workforce necessity, proper utilization of resources and to meet the client"s demand precisely before the beginning of real construction work. Engineers can also monitor detailed construc-tion work during realization and simulate on-site activities with the table-work. This paper is aimed to analyse some pro-jects, identify the common project failures and common reasons behind the failures of those projects. Analysis of re-search papers for some proposed visualization systems for pre-project estimation was done throughout the paper. In addition the author proposes visualization and project monitoring approaches encouraged by indoor navigation systems. Workflow with augmented reality during...

Augmented and Virtual Reality in Construction: Drivers and Limitations for Industry Adoption
Journal of the Construction Division and Management, 2020
Augmented and virtual reality have the potential to provide a step-change in productivity in the construction sector; however, the level of adoption is very low. This paper presents a systematic study of the factors that limit and drive adoption in the construction sectorspecific context. A mixed research method was employed, combining qualitative and quantitative data collection and analysis. Eight focus groups with 54 experts and an online questionnaire were conducted. Forty-two limiting and driving factors were identified and ranked. Principal Component Analysis was conducted to group the identified factors into a smaller number of factors based on correlations. Four types of limiting factors and four types of driving factors were identified. The main limitation of adoption is that AR and VR technologies are regarded as expensive and immature technologies that are not suitable for engineering and construction. The main drivers are that AR and VR enable improvements in project delivery and provision of new and better services. This study provides valuable insights to stakeholders to devise actions that mitigate the limiting factors, and that boosts the driving factors. This is one of the first systematic studies that presents a detailed analysis of the factors that limit and drive adoption of AR and VR in the construction industry. The main contribution to knowledge of this study is that it grouped and characterized a myriad of limiting and driving factors into easily understandable categories; so that, the limiting factors can be effectively mitigated, and the driving factors potentiated. Also, a roadmap with specific short term and medium-term actions for improving adoption has been outlined.
Measuring the potential of augmented reality in civil engineering
Advances in Engineering Software, 2015
Recently building information models have substantially improved the explicit semantic content of design information. Information models are used to integrate the initial phases of project development. On the construction site, however, the designs are still mostly represented as line-based paper drawings or projections on portable displays. A generic technology that can integrate information and situate it in time, place and context is augmented reality. The specific research issues addressed are (1) does augmented reality have a potential use in civil engineering, (2) how big-in comparison to other technologies-is this potential and (3) what are the main barriers to its adoption. The generic research issue was to develop a methodology for evaluation of potentials of technology. A prototype was built. It was tested on a real construction site to evaluate the potential of its use using the action-research method. A set of structured interviews with potential users was then conducted to compare the prototype to conventional presentation methods. Using this methodology it has been found out that augmented reality is expected to be as big a step as the transition from 2D line drawings to photorealistic 3D projections. The main barrier to the adoption is immature core virtual reality technology, conservative nature of construction businesses and size of building information models.
Computer Visualisation as a Communication Tool in the Construction Industry
2001
Coinpiiter visualisation tools offer good visiialisation capabilities that cannot be achieved rising traditional methods, such as 2 -0 drawings. Design details are not always simple arid easy to understand. Builders may spend considerable time on interpreting diflciilt or complex details in a drawing; this could result in buildability problems. Computer visualisai'ion tools have considerable potential to improve this aspect of construction. However, their use is still at present limited and not filly understood. This paper presents an ongoing research project demonstrating the possible rise of computer visualisation as a conimunication tool for desig,? itlforniation and to support collaboration between construction participants (designers and contractors). An industn. survey hus been conducted to investigate the ciirrent use of c<sniputer visualisation in the construction industry. A sunininn of the survey results is presented in this paper orid the outline features of a new visualisation tool is presented.

Most previous Reality Capture Technology (RCT) research in construction focuses on the technical aspects of data collection, processing, and post-processing, while fewer studies have explored stakeholder perceptions about adopting and implementing RCT. This research investigated the perceptions of various construction project stakeholders in the commercial and infrastructure sectors regarding the benefits of, and obstacles hindering, the adoption of RCTs. A survey was distributed to the membership of U.S.-based professional organizations. Exploratory Factor Analysis was implemented to investigate and confirm logical and consistent empirical groupings of the benefits and obstacles listed in the survey. In general, mean comparisons revealed consistency across stakeholder perceptions of the benefits and obstacles of RCTs. However, significantly different perceptions about the increased accuracy of prefabricated elements, RCTs not being a company priority, lack of company budget, and da...
Visualization in 4D Construction Management Software: A Review of Standards and Guidelines
Computing in Civil and Building Engineering (2014), 2014
Visualization of construction schedules has much improved through the development of 4D modeling tools that offer an effective method for schedule planning and management. While increasingly used by the construction industry, existing 4D tools are being continually improved, and many new tools are being developed, especially with the increased adoption of building information modeling (BIM). The ability to observe the animated sequence of the construction process and track the construction status of each building component is just one of many possibilities offered by 4D modeling applications. However, as with the proliferation of any new technology, one of the inherent challenges with 4D modeling tools is a lack of agreed upon visualization standards for representing building elements and tasks. Specifically, each tool typically has its own standards for viewing and navigating the model and schedule. Interviews with AEC professionals and experts provide insights from the end-user perspective of the current visualization methods along with their recommendations. To start addressing some of these challenges, our team reviewed the current status and methods for visualizing construction schedules, building on the research efforts in the domains of information visualization and human-computer interaction. Based on the current experiences and feedback from AEC industry practitioners, a set of visualization guidelines for representing the construction process was developed, which supports future efforts in 4D model use and development.
Visualisation in architecture, engineering and construction (AEC
Automation in Construction, 2005
In the architecture, engineering and construction industries, computer visualization usage can cover the whole lifecycle of a product from presentation of initial concepts to the final stages of production and can also extend to maintenance issues. Threedimensional walkthroughs can be created from hand drawn sketches at the very early stages of the design process. Threedimensional models can be used by design teams to communicate design intent to client and users and to compare and evaluate design options. During more advanced stages of design, three-dimensional representations can be used to check the integrity of services coordination, accessibility and maintainability. During construction, visualization can facilitate the interpretation of design details by site operatives. The concept of visualization is not limited to modeling physical objects but can extend to the representation of abstract data sets of the type obtained from simulation programs used in performance assessment or from Computation Fluid Dynamics (CFD) applications. This paper will review the application of visualization in the process of design and construction and then present findings from three research projects that made use of some of these techniques at various stages of the process: for collaborative working during concept design stage, for design development and marketing in the house building sector, and for the modeling of design details during the construction stage.
