“…The goodness-of-fit statistics, such as the PLS SEM Algorithm and Q2 values, let us evaluate the model's overall fit and estimate its predictive capability [ 2 , 69 ]. Overall, the SEM method with Smart PLS 4 provided us with a potent instrument for examining the correlations between the components in our model [ 80 ]. We were able to find the relevant routes and evaluate the relative relevance of the various constructs in explaining the variance in the dependent variable by applying this method [ 75 ].…”

The application of metaverse technology in the field of civil engineering has the potential to improve project efficiency and accuracy. Nevertheless, the pervasive adoption and effective integration of metaverses are contingent on a number of crucial factors. This study investigates the critical factors underlying the successful implementation of metaverse technology within a business context. This research employs a comprehensive mixed-method approach comprised of exploratory factor analysis (EFA) and structural equation modelling (SEM) to examine survey responses gathered from seasoned professionals in the architecture, engineering, and construction (AEC) sectors in Bangladesh. In areas such as communication and collaboration, design visualization, and monitoring and maintenance, the construction industry has made extraordinary strides. As imperatives for managerial consideration strategic investment in resources, targeted training initiatives, heightened awareness campaigns, and prudent deployment of cost-effective and efficient metaverse-based solutions emerge, future investigations should include a larger sample size and an evaluation of the lasting effects over extended time periods. The key to unleashing the full potential of the metaverse within the architecture, engineering, and construction industries lies in addressing these identified success determinants, thereby ushering in enhanced project outcomes and enhanced efficiency within the constructed environment. The combination of these initiatives is expected to pave the way for a new era in the AEC landscape.

“…The ultimate aim is to attain objective functions without compromising any of the responses. The desired values, which are between 0 and 1, are what matter in the optimization process for each response, which ranges from 0 to 1 (Waqar et al, 2023b;Khan et al, 2023). Elevating the DJ value enhances the favourability of the outcome, often represented as a percentage.…”

The use of rubber aggregates derived from discarded rubber tyres in concrete is a pioneering approach to replacing natural aggregate (NA) and promoting sustainable building practices. Recycled aggregate in concrete serves the dual purpose of alleviating the accumulation of discarded rubber tyres on the planet and providing a more sustainable alternative to decreasing natural aggregate. Due to fact that the crumb rubber (CR) decreases the strength when used in concrete, incorporating titanium dioxide (TiO2) as a nanomaterial to counteract the decrease in strength of crumb rubber concrete is a potential solution. Response Surface Methodology was developed to generate sixteen RUNs which contains different mix design by providing two input parameters like TiO2 at 1%, 1.5%, and 2% by cement weight and CR at 10%, 20%, and 30% as substitutions for volume of sand. These mixtures underwent testing for 28 days to evaluate their mechanical, deformation, and durability properties. Moreover, the compressive strength, tensile strength, flexural strength and elastic modulus were recorded by 51.40 MPa, 4.47 MPa, 5.91 MPa, and 40.15 GPa when 1.5% TiO2 and 10% CR were added in rubberised concrete after 28 days respectively. Furthermore, the incorporation of TiO2 led to reduced drying shrinkage and sorptivity in rubberized concrete, especially with increased TiO2 content. The study highlights that TiO2 inclusion refines pore size and densifies the interface between cement matrix and aggregate in hardened rubberized concrete. This transformative effect results in rubberized concrete demonstrating a commendable compressive strength comparable to normal concrete.
