Applications of Augmented/Mixed Reality Head-Mounted Displays in the Construction Industry
In the last two decades, the construction industry has begun to adopt new technologies to help improve safety and quality and minimize time and costs associated with construction projects. Industries combining the use of virtual and physical data discovered that most mistakes arise due to a disconnect between a user’s view of the real world and what they are comparing it to in 2D sketches or a 3D model. This disconnect is one of the major contributing factors to costly change orders during project execution. The use of optical Head Mounted Displays (HMDs), capable of superimposing holographic images into a real-world space, is being considered by several researchers and practitioners as a possible remedy. HMDs use the augmented/mixed reality concept as a platform for their execution. These advancements are leading us to entirely new ways of thinking and visualizing construction processes. The future of technology in the construction industry points to wearable technologies, though more research is required before HMDs or similar technologies can be readily used. Many of these technologies are currently in the beta-testing stage and require further examination before being implemented on a larger scale. This pilot study identifies applications of HMDs in the construction industry. Microsoft HoloLens is tested as a potential visualization tool to determine its usefulness and limitations in comparison to traditional 2D sketches or 3D models.
Factors Hindering the Incorporation of Virtual Design and Construction Services into Construction Management Firms in the Southeastern United States
Due to the complex and fast-growing nature of the technologies associated with virtual design and construction (VDC), many companies and owners have begun to discuss and establish recommended best practices. However, there is a disparity between the perceived usefulness and value when implementing VDC services. The tools are there but very few companies fully understand or fully embrace what VDC services are capable of, both for their company and the industry as a whole. Consequently, there is a need to discover and analyze the hindrances to the implementation of VDC services. With an online survey, this study sought to identify the hindrances that are troubling the adoption of VDC services within construction management companies in the Southeastern United States. Results from the survey indicate that a large number of the companies have VDC departments and several were able to share common issues that hampered their efforts with using and paying for VDC services. For those companies that did not have VDC services to offer, poignant opinions were recorded that seemed to affirm why technology adoption struggles in the construction industry.
A Market Survey of BIMFM Readiness Among Designers and Builders in the Southeast United States
The use of Building Information Modeling for Facilities Management (BIMFM) uses a data-loaded model as a single repository for O&M information. The BIMFM model can replace the need for referencing multiple documents to obtain comprehensive asset information. Previous research has shown that the implementation of BIMFM by owners is still in its infancy due to a lack of skills, quantitative ROI, and culture; however, based on data collected in this research, many owners are still requiring data-loaded, as-built models. This research analyzes, with a mixed-methods survey, the BIMFM market readiness of designers and builders through the lens of previous experiences with BIMFM, modeling capabilities, and company infrastructure. The survey revealed that 83.3 percent of the respondents have identified, bid on, or won a project that had a BIM Execution Plan/BIM Guidelines required in the contract, with 50 percent of the respondents executing a contract that required a data-loaded, as-built 3D model for BIMFM purposes. Although the frequency of these projects is quite low, the expertise within the majority of the companies relies on 15 percent or less of the managers. The market is willing to execute these contracts with the small percentage of experienced BIM experts, but future growth would require investment to develop more BIMFM experts.
