Research has identified various beneficial capabilities for augmented reality technologies in the AEC industry such as virtual site visits, comparing as-built and as-planned status of projects, pre-empting schedule disputes, enhancing collaboration opportunities, and planning/training for similar projects. This paper provides an expanded foundation for future research by presenting a statistical review of augmented reality technology in the AEC industry. The review is based on articles found within eight well-known journals in architecture, engineering, construction, and facility management (AEC/FM) until the end of the year 2012. The review further narrows the literature within these journals by considering only those 133 articles found through a key word search for “augmented reality.” The selected journal articles are classified within the following dimensions: improvement focus, industry sector, target audience, project phase, stage of technology maturity, application area, comparison role, and technology. The number of articles within these dimensions are used to identify maturing and emerging trends in the literature as well as to synthesize the current state-of-the-art of augmented reality research in the AEC industry. In summary, the AR literature has increasingly focused on the demonstration of visualization and simulation applications for comparison of as-planned versus as-built statuses of the project during the construction phase to monitor project progress and address issues faced by field workers. In addition, the future trend is toward using web-based mobile augmented systems for field construction monitoring.
KeywordsAugmented reality AEC industry Project phase Construction management Literature review
The complex nature of the architecture, engineering, construction, and facility management (AEC/FM) industry and its high demand for access to information for evaluation, communication and collaboration, increases the industry’s need for information technologies. Recent visualization technologies such as virtual and augmented reality technologies are ideal in this environment.
Overview of augmented reality
Augmented reality gives a view of the real world where elements are superimposed by computer generated files such as graphics, sounds, videos, or digital information. From the first see-through head-mounted AR display developed in the 1960s by Ivan Sutherland at Harvard (Sutherland, 1968), to the enhanced HD4AR and Mobile Augmented Reality System (MARS) developed by Golparvar et al. (Bae et al. 2012), augmented reality technologies have been used in various disciplines and arenas, e.g. engineering, entertainment, aerospace, medicine, military, and automotive industry, as a frontline technology to meet visualization difficulties in their specific domain (Behzadan and Kamat 2011).
The AEC industry is also moving to embrace more AR technologies for improving various stages of construction projects. This advanced computer technology provides significant advantages through simulation and visualization of the construction industry, e.g., allowing the observer to interact with both the actual and the virtual objects and to monitor the construction progress by comparing the as-planned and as-built status of the project (Shin and Dunston 2008). AR technologies can benefit the AEC/FM industry in at least three levels: visualization, information retrieval, and interaction (Dong and Kamat 2013). Various applications of AR have been recommended for the AEC/FM industry by different researchers. Dunston and Wang (2005) proposed AR systems for AEC industry to support all phases of the constructed facility project life cycle. Wang et al. (2007) explore potential AR applications in heavy construction equipment operator training. Golparvar-Fard et al. (2009) developed a 4-dimensional AR model for automating construction progress monitoring, data collection, processing and communication in construction phase of the project. Behzadan et al. (2011) investigate a mobile 3-dimensional AR system for visualizing dynamic site operations during the construction phase. Waugh et al. (2012) developed a web-based augmented panoramic environment to document construction progress. Park et al. (2013) presented a conceptual framework that integrates AR with building information modeling (BIM) to detect construction defects. These applications demonstrate the potential of this technology for future use in this domain.
Although the application of augmented reality technologies in construction projects has tremendously increased in recent years, these technologies are still in the research stage and their full potential is not fully achieved. There are limitations that should be addressed before these technologies will become dominant in the AEC industry such as tracking technologies, and rendering software. Moreover, appropriate application areas for different types of AR will continue to evolve.
Historically, many AR technologies were not applied on construction sites due to tracking and alignment problems, instead they were generally used at the home office for simulation or collaboration during the design phase of a project. However as the technology developed in recent years, the majority of these technologies have been used on construction sites for progress monitoring and defect detection. Moreover, trend analysis shows that web-based and wireless network technologies are becoming more and more popular in recent years, and these types of AR technologies are interesting technologies for further research and application.
A list of various input mechanisms, output mechanisms, and tracking technologies for AR systems can be found in Wang (2009). Portable and mobile AR systems including: radio-frequency based tracking technologies such as GPS, WLAN, indoor GPS; infrastructure-dependent technologies such as fiducial markers; infrastructure-independent tracking technologies such as gyroscopes; and image-based tracking techniques have been studied in many research projects (Bae et al. 2013). Moreover, using cloud computing technologies for web-based and ubiquitous AR systems has been explored in recent years (Wang et al. 2013).
Shin et al. (2008) study various application areas for augmented reality technologies in industrial construction based on technology suitability. The research assesses different work tasks from the human factors perspective and presents a comprehensive map, which identifies eight work tasks including layout, excavation, positioning, inspection, coordination, supervision, commenting, and strategizing out of seventeen classified work tasks which could potentially benefit from AR systems.
Wang (2009) gives a detailed review of AR in the AEC industry, and gives a review of several major research efforts prior to 2009, and categorizes various AR technologies with their advantages and disadvantages.
Wang et al. (2013) reviews 120 articles published between 2005 and 2011 in various journal and conferences databases with a focus on augmented reality technologies in the built environment. The paper classifies all available toolkits for augmented reality prototyping in five categories: 2D marker AR-PC and web-cam based, 2D marker AR-mobile, 3D object recognition-mobile, marker-less tools, GPS-compass based AR. In their research, AR literature is classified in three categories: (1) application area; (2) AR system layers: concept and theory (with four sub-layers including: algorithm and modeling, conceptual framework, evaluation framework, and technology adoption), implementation (with two sub-layers: software and hardware), evaluation (with two sub-layers: effectiveness and usability), and industry adoption; (3) other technical criteria. The paper explores state-of-the-art technologies in each category and proposes future research directions.
Chi et al. (2013) discusses trends in AR applications for the AEC/FM with a specific focus on four AR technologies: localization, natural user interface, cloud computing, and mobile devices. The paper reviews 101 articles and outlines future trends and opportunities for applying AR in the AEC/FM industry in six directions: (a) field exploration based on hybrid localization, (b) in-field gesture or kinesthetic control of AR interface, (c) integration with location-specific information, (d) accessing field information using ubiquitous services, (e) portable AR devices in the field, (f) context-aware augmented reality in AEC/FM fields.
To apply AR technologies in AEC projects efficiently and to achieve their full potential in this domain, it is essential to systematically identify application areas in which AR can be used for better performance. This statistical review seeks to answer to these questions: what are key AR application areas in the AEC industry based on suitability of AR technologies? what are the gaps in this area which can potentially benefit from AR technologies? Based on future trends, predict how AR technologies can be further improved for future applications?
This paper presents an in-depth statistical literature review of augmented reality technologies in construction industry over a fourteen-year period (1999–2012). The goals of this review are (1) to synthesize the current state-of-the-art and trends of augmented reality technologies for construction projects, and (2) to identify key application areas which could significantly affect the construction industry. These goals are accomplished by classifying the literature in categories defined by the authors found in the literature.
The scientific contribution of this review is the presentation of a comprehensive multi-dimensional categorization for specifying AR technology and characteristics in the AEC industry. This literature review gives the researcher a broad view of the stage of AR technology maturity in built environment, which can be used to guide new augmented reality system design as well as to help evaluate existing systems for the construction industry.
This paper offers construction practitioners and researchers an assessment of the application areas of augmented reality technologies including the purposes for which these technologies have been applied in different project phases. The paper qualitatively aggregates the results of 133 research studies of AR technologies in construction projects to show researchers and practitioners how augmented reality models have been applied to address project challenges. Based on the trend analysis that is conducted, past research is studied and future research directions are recommended.
This paper is an extension of our conference paper (Rankouhi and Waugh 2012); the research methodology is similar to the methodology used previously. Five new journals are added to our database: the ASCE Journal of Computing in Civil Engineering (CCE), the Journals of Advanced Engineering Informatics (AEI), the Journal of Computer Aided Civil and Infrastructure Engineering (CACIE), the Emerald Journal of Engineering, Construction and Architectural Management (ECAM), and the Emerald Journal of Construction Innovation Information, Process, Management (CIIPM). These journals cover a wider range of database in civil engineering research domain, and increase the number of selected articles. In addition, five new dimensions (research methodology, improvement focus, industry sector, comparison role, and location) and various new categories are added to our previous defined dimensions.

Categorization of the articles
This section discusses the classification of the current state of AR technology literature in the AEC industry. For all but three sub-sections, the articles are classified based on their principal focus and each article is counted once. The exceptions to their approach are sub-sections 5.1, 5.4, and 5.8; in these sub-sections instead of selecting a single “principal focus,” we identified the categories to which the article “made reference.” In these three sub-sections only we report percentages and do not report counts.
In this section articles are classified based on their research methodology which is divided in five categories: case study, experimental/empirical study, proof of concept (or proof of principle study), questionnaire (survey/interview), and literature review.
A case study is a research method in which detailed consideration is given to the development of a particular case over a period of time. An experimental or empirical study is an empirical scientific method in which an experiment arbitrates between competing models or hypotheses. A proof of concept or a proof of principle study is a research method in which a certain method or model would be recognized to demonstrate its feasibility or to verify that a certain concept, theory, or prototype has the potential of being used. Questionnaires (as well as surveys and interviews) are research techniques in which qualitative and qualitative data analysis could be conducted based on the information gathered from research participants. Literature review (historical and documentary research, trend studies), is a research method which considers the critical points of current knowledge including substantive findings as well as theoretical and methodological contributions to a particular topic (Cohen et al. 2007).

Proof of concept
Articles are classified in four categories based on where the improvement which the article proposes would occur: (1) AEC industry, (2) organization, (3) projects, and (4) individuals. Moreover the organization category is divided into three subcategories of organization type including: (a) facility owner, (b) designer, and (c) contractor.
In the construction industry various project types can benefit from AR technologies including: (1) municipal/infrastructure, e.g., evaluation of dynamic city models and an emission model for transportation (Aschwanden et al. 2012), (2) residential, e.g., virtual and augmented reality for designing and customizing mass housing (Duarte 2005), (3) building/commercial, e.g., visualizing high-rise building construction strategies (Russell et al. 2009), and virtual and augmented reality technologies for maintenance of exterior closures and interior finishes of walls and in the construction of buildings (Sampaio et al. 2012), (4) heavy/highway, e.g., developing virtual reality system for optimized simulation of road design data (Kang L. S. et al. 2010), and segmentation and recognition of highway assets using image-based 3D point clouds and semantic Texton forests (Golparvar-Fard et al. 2012), and (5) industrial, e.g., application areas for augmented reality in industrial construction (Shin and Dunston 2008).
Reference article for industry type dimension
Wang et al. (2012)
Due to the complexity of construction projects and the collaborative nature of the AEC industry, the application of AR systems has a wide range of target audiences. To classify these articles the following audiences were chosen partially based on Muramoto et al. (2008): (1) worker, e.g., machine operators and technicians, (2) design team, e.g., architects, interior and exterior designers, (3) schedule and budget professional, in particular referred to as project manager, (4) building systems engineer, e.g., structural, mechanical, and electrical engineers, (5) inspector, e.g., project safety officers (6) engineering student, (7) project end user, e.g., building occupants, office employees, (8) other stakeholder, e.g., clients, and building owners. If an article proposed a change in, or enhancement of, the work of one of these audiences, it was classified in that category.

Stage of technology maturity
From a stage of technology maturity perspective, the articles are divided into five categories: (1) theory, (2) framework, (3) sub-system technical issues, e.g., investigation of tracking, positioning and orienting issues for AR-based technology for steel column inspection (Shin and Dunston 2010), (4) proposed system development, e.g., development of ARVISCOPE (AR animation scripting language) and ROVER a mobile computing framework for information modeling and simulation of construction operation (Behzadan et al. 2011), and (5) system application demonstration and production, e.g., application of D4AR for construction progress monitoring (Golparvar-Fard et al. 2011a), application of AR Training System for training the operation of heavy construction equipment (Wang et al. 2007).

Sub-system technical issues
Augmented reality technology has many applications in the AEC industry. We classify AR application areas in the AEC industry as follows: (1) visualization or simulation, (2) communication or collaboration, (3) information modeling, (4) information access or evaluation, (5) progress monitoring, (6) education or training, and (7) safety or inspection.

Construction participants use augmented reality technologies to compare different statuses of a project. Articles that “make reference” to the comparison role of AR technologies are divided in two categories; (1) comparison modes: (a) reality versus reality, e.g., comparing two construction site 360 degree panoramas at two different times for virtual reality documentation of Inuvik Super School (Waugh et al. 2012), (b) model versus reality, e.g., integrating sequential as-built and as-planned representation with D4AR tools (Golparvar-Fard et al. 2011a), and (c) model versus model, e.g., the application of Experimental Virtual Environment (EVE) (Savioja et al. 2003); and (2) comparison purpose, e.g., progress monitoring, defect detection, validating the model, updating the model, and evaluating the model.

Reference article for comparison purpose dimension
Augmented reality technology, which typically layers virtual information on a real scene, utilizes different hardware (personal computers (PC), laptops, head mounted displays (HMD), GPS, data gloves, smart boards, etc.) and software (AutoCAD, Photoshop, AC3D, 3D Studio, building information model (BIM), etc.). From a technology perspective articles are classified into three categories: (1) user experience: (a) immersive or (b) non-immersive, i.e., desktop-based; (2) device: (a) mobile, (b) stationary or non-mobile; (3) delivery: (a) web-based, (b) standalone.
Devices such as HMD and data-gloves create immersive AR systems, in which users feel immersed in a virtual environment just as they usually feel in a real environment. Due to the improving performance of handheld devices and recent solutions to technical difficulties such as tracking, there is an opportunity for augmented reality systems to become portable, as well there is a growing interest in the use of mobile AR applications. Web-based augmented reality technologies can deliver project information to remote locations and are very useful to manage virtual projects around the globe. Finally, due to the wide range of AR applications, these technologies can be used both on-site for progress monitoring and in an office (not-on-site) for design control.

Augmented reality technologies can be applied in different locations during a construction project. From a location perspective, AR technologies can be classified in two categories: (a) field, e.g., using robot-aided tunnel inspection and maintenance system on construction site (Victores et al. 2011), (b) home office, e.g., virtual environments for synchronous and remote collaborative design (Germani et al. 2012).
The following results are concluded for the categories defined in this research.
Journals: Automation in construction has the highest overall number of articles among the journals. The maximum number of AR technology articles published in these eight journals in a single year, occurred both in 2011 and 2012. Eighty-three percent of the articles were published in most recent five years.
First authors: USA, with more than half of articles, is the dominant residence of the first authors.
Research methodology: Case studies and experimental studies with 32% and 31% respectively, are the most frequent research method among selected articles.
Improvement focus: The majority of the articles focus on projects rather than on the AEC industry, organization or individual level.
Industry sector: building/commercial with 35% have the highest number of articles, whereas, residential have the least number of articles.
Target audience: The most frequent focus is the workers (e.g., machine operators and technicians), whereas the least focus is on project end users.
Project phase: The most frequent focus is the construction phase with the maintenance phase being next with approximately half as many articles. Twenty-six articles cover two phases (e.g., initiation/design) or all phases. Procurement phase shows a lack of focus in the area of AR systems.
Stage of technology maturity: The most number of articles focus on AR system application rather than system development or sub-system technical issues.
Application areas: Approximately half of the articles had a principal focus on visualization/simulation or communication/collaboration, and just a few articles focus on education/training and safety/inspection.
Comparison role: 47% of the articles made reference to the comparison role of augmented reality technologies for comparing different statuses of projects. More than half of those articles focused on comparing a model with a reality to monitor progress and detect construction defects. Comparing model vs. model captured the least attention in this area. In addition, majority (%60) of the comparison articles focus on field audience (for progress monitoring and defect detection), while less than half of the comparison articles focus on home office audience (for model improvement).
Hardware system: From the user-experience perspective most of the articles discussed non-immersive technologies. From the delivery perspective, most of the articles discussed standalone technologies, and from device perspective, most of the articles focus on non-mobile technologies. A spike in the number of articles focusing on mobile technologies occurred in 2011.
Location: The most frequent focus is AR technologies which can be applied in the field (rather than in the home-office). The field category included almost 80% of those articles which referred to a location.
Total number of articles
AR technologies provide proven benefits especially in the areas of visualization/simulation and communication/collaboration, however these benefits are not yet widely adopted by AEC industry participants nor have they been incorporated into industry-wide workflow processes. As a result, industry participants choose to pilot (i.e., system development and application) AR technologies on a few projects rather than adopting or piloting the technology across their organization.
Building/commercial projects provide a good test bed for visualization and communication of different perspectives of a project, since these projects typically entail more complexity and more need for integration than an infrastructure, heavy/highway, or residential projects. However, the trend in the most recent five years shows that heavy/highway projects are getting an area of focus for new AR technologies. We also predict that use on industrial projects will grow rapidly as technologies are improved and confidence is gained.
We predict expansion of AR technologies from a principal role in the construction and maintenance phases to other phases (especially the design and procurement phases) as the ability to compare virtual models with previous virtual models (and realities with previous realities) to monitor project progress and detect construction defections, rather than the narrow focus of comparing a current construction phase reality with a final design phase model.
The uniform distribution of target audiences among the design team, the project management team, and on-site personnel reflects integration being the essential purpose of AR technologies.
We predict continued growth in the use of internet and web-based devices to enhance integration of perspectives. Collaborative, ubiquitous, and internet-based AR systems enable users to update and synchronize the information from a remote location. Cloud computing technologies could help next generation construction professionals to access massive amount of field information such as BIM rapidly and conveniently (Chi et al. 2013).
We also predict continued growth in the use of mobile and portable multi-user AR devices to display (and capture) models and realities. The next generation mobile technologies are likely to have natural user interface (Wang et al. 2013), which would be controlled by human movement and gestures, and makes it easy for field workers to use AR systems on construction sites. It is also predicted that next generation mobile AR systems would have context-aware and location-aware applications. We also speculate that the cost of immersive hardware is, and will continue to be, an impediment to its widespread use.
A structured methodology was used to identify 133 articles on the topic of augmented reality from eight prominent AEC industry journals. The first article was published in 1999; a significant increase in the number of articles on this topic occurred during the year 2008. In addition to statistics on the counts of articles by year and the first author’s country of residence, ten interpreted dimensions were developed for classification of these articles. Literature show field workers and project managers have high interests in using non-immersive and desk-top standalone (individual) AR technologies during construction phase of a project to compare as-planned versus as-built statuses to monitor progress and defect detection. Whereas, it is predicted that future trend, is more toward using collaborative and internet based mobile AR systems which have applications not only in construction phase, but also in procurement and maintenance phases of a project. Due to various benefits of AR technology for construction industry, the application of AR systems for initiation and procurement phase of a project to compare model vs. model and reality vs. reality is recommended. Moreover, lightweight mobile and immersive AR systems are also recommended for field personnel due to dynamic environment of construction fields.
Based on this review, our recommendation for researchers in the area of AR technology is that the current trial systems should have narrow applications and there is an essential need for more comprehensive systems. There is an opportunity for more research on the application of AR systems during the procurement phase of construction projects, since literature shows a lack of research in these phases of project. In addition, the assessment of success of developed systems should be validated by researcher and practitioner from academy and industry. From a theory and framework perspective, integration of multiple projects (within an organization) and integration of multiple organizations (within the industry) could be a considered for future research in the area of AR systems. Integration might be easier in less complex types of work, i.e., residential projects. Comparisons are fundamental to AR system within the AEC industry to be able to monitor projects and defect detections, therefore, our testing of five comparison purposes (progress monitoring, defect detection, evaluating the model, updating the model, validating the model) need to be further investigated.
We assume that construction industry practitioners would assess an AR system based on the system contents, features, and value. From the content perspective they would seek current (possibly real-time) information as well as a historical record that may be integrated with traditional project information (e.g., BIM). From a feature perspective, they would seek a user friendly interface (possibly internet-based) that can be integrated into their content workflow process and that facilitate the comparison of project statuses over time. From the value perspective, they would seek an affordable cost (initial and ongoing) for which the payback period is short. We assume the benefits of AR contribute to this payback are virtual site visits, defect detection, pre-empting dispute resolution, photographic as-built, and training of personnel. Currently, most of systems found in the literature are trial/demonstration, hence they are developed for specific purposes they do not have all of the above criteria, however some new systems offers some valuable feature and may provide a competitive advantages. As the technology is rapidly evolving, it is recommended to the construction participants to monitor this developing area closely in order to get the latest update.
