A review of innovations in mobile and remote inspection technologies for the construction industry (2020 to 2025)

This paper reviews recent innovations in mobile and remote inspection technologies applied to the construction industry from 2020 to 2025. Using a structured literature review of 673 peer-reviewed studies retrieved from Scopus, the study synthesises trends in Building Information Modelling (BIM), cloud-driven platforms, Internet of Things (IoT), unmanned aerial vehicles (UAVs), robotics, and artificial intelligence (AI) applications. Results indicate that digital and ICT frameworks dominate research output, followed by AI-based defect detection and innovations in construction materials. In contrast, UAV-enabled inspection and IoT integration remain underrepresented although they are highly relevant to safety and accessibility. The analysis highlights benefits such as reduced inspection time, improved accuracy, and enhanced stakeholder communication, while persistent barriers include cost, interoperability, and digital literacy challenges, especially for small and medium-sized enterprises (SMEs). The review identifies a research gap in integrating emerging tools such as digital twins, robotics, and renewable energy linked inspection frameworks. It concludes with recommendations for cost-effective deployment, targeted training, and regulatory support to strengthen the adoption of Construction 4.0 practices.
