Precast and 3D sandwich wall panels represent a recently developed technology that combines structural efficiency, thermal insulation, and rapid construction performance. These panels consist of two concrete layers separated by a lightweight core such as expanded polystyrene foam, which offers significant thermal insulation and load bearing capacity, especially in connection systems subjected to both lateral and vertical loading. The experimental studies reported that ultra-high performance fiber reinforced concrete (UHPFRC) sandwich panels achieved up to 60% of higher flexural strength and improvement in thermal insulation compared with conventional concrete panels, confirming their thermo – mechanical efficiency. Additionally, the fabrication process has been refined to enable faster production, improved reliability, and adaptable modifications to meet diverse architectural requirements. These enhancements contribute to improved energy efficiency, durability, and overall sustainability in building performance. This review focuses on the integration of high-performance concrete (HPC) and fiber-reinforced polymer (FRP) and explores recently developed construction techniques such as precast fabrication, tilt-up methods, and shotcrete applications, along with their structural performance. Moreover, the paper discusses recent studies where advanced numerical tools such as ANSYS and ABAQUS have been utilized to optimize structural design, evaluate seismic and dynamic response, and assess thermal performance. The review also addresses sustainability, cost-effectiveness, and expanding architectural possibilities allowed by these systems. This study highlights the current challenges and future research directions aimed at enhancing the performance and application of these advanced construction components.
