Augmented Reality Model for Underground Construction of Electricity System and the Evaluation of Model Adoption Using FUZZY AHP

Abstract

Augmented Reality (AR) modeling is recognized as a promising analysis tool and visualization technology of extended reality application in many practices including infrastructure planning and management. Adopting AR technology for underground construction of electrical system not only offers an engineering model development to potentially reduce the economics losses from accidents and work zone delay but also provides strategic response to support the eco-friendly development and livability in compliance with smart city concept in the National Strategy (2018-2037) and Provincial Electricity Authority (PEA) strategics plan. This research aims to develop AR model for underground construction of electrical system and to evaluated AR model adoption by Fuzzy Analytical Hierarchy Process (Fuzzy AHP). According to the development of AR model and its application of PEA construction project using Horizontal Directional Drilling (HDD) technique in Phetchaburi province, it is envisioned that this research presents AR model for underground construction in pre-construction, construction, and post-construction stages by taking account of the PEA requirements, and relevant guidelines. AR model can support all construction stages and can visualize complex workplace situations in both construction and training paradigm. In order to evaluate AR model adoption, this research applied Fuzzy AHP to prioritize influencing factors and alternatives of model adoptions by analyzed survey data of 30 correspondents from PEA, Department of Highway, Department of Rural Road, National Telecom Public Company Limited, Provincial Waterworks Authority, Provincial Administrative Organization. As a result, the influencing factors affecting model adoption are hardware and software limitations, organizational factors, Implementation, and caliber or worker performances, respectively. The model integration of 3D and AR is the influential model for underground construction of electrical system with the highest priority of model deployment followed by 2D model, and the integrated 2D and 3D model, and AR model, respectively. It is challenging to balance the level of AR development and the accuracy of model and alignment. Sharing and integrating national infrastructure network and database can help increase the efficiency of model and technology adoption.
