Fig. 3. Comparison chart between conventional and "smart" methods for structural health monitoring and the measurements they perform.

In Fig 3 is possible to observe a wide range of measurements that can be conducted by both conventional sensors and smart sensors. However, a particularly interesting point is the disparities in the measurements performed by each group. The discovery that smart sensors conduct measurements distinct from those possible with conventional sensors serves as evidence that these devices did not emerge with a proposal to replace previously utilized devices. Instead, they serve as a complement, expanding the scope and precision of structural monitoring with the introduction of new methods and technologies. 5 Conclusions Advancements in studies on smart concrete sensors for Structural Health Monitoring (SHM) of reinforced and prestressed concrete assets mark a significant progress in the field. Traditional methods often rely on labour-intensive on-site testing, face accessibility challenges, and are affected by environmental conditions. Smart concrete sensors offer continuous, high-quality data collection and analysis, enhancing SHM accuracy and reducing labour and repair costs. Early detection of structural issues prolongs asset lifespan and minimizes environmentally impactful interventions. This study emphasizes SHM's role in early anomaly detection, performance evaluation, and maintenance optimization, leading to substantial cost savings and extended structure life. Collaboration among construction professionals, engineers, and researchers is essential for further SHM technology refinement, ensuring structures remain resilient in evolving environments. The integration of smart sensors into SHM systems offers a promising path for safer, more efficient, and sustainable infrastructure management. This study contributed to the in depth understanding of Structural Health Monitoring in construction and its benefits, serving as a basis for future research and practical application. As the field of SHM continues to evolve, it is fundamental that construction professionals, engineers, and researchers continue to collaborate, to improve techniques and promote the safety and sustainability of structures built in changing environments.
