Supply Chain Digital Twins for Modular Timber Construction: Monitoring Durability and Circular Reuse

The shift towards sustainable and circular building systems has placed modular timber systems in the limelight as an alternative with lower carbon footprints. Nevertheless, the durability of the used material and the efficiency of the reuse cycle are factors that are now significantly impacted by digitalization. In the investigation described in this article, the influence of overall Supply Chain Digital Twin maturity and overall Supply Chain Responsiveness on Timber Durability and the overall Reuse Potential of Timber in the emerging modular timber buildings in Jordan was investigated. In the research design adopted for the quantitative approach, using Python software for the analysis of the results of the survey conducted using the questionnaire administered to 131 respondents in the industry. The results showed that DTM had a remarkably positive effect on TD (β = 0.43, p < 0.001) and CRP (β = 0.57, p < 0.001), accounting for 35% and 49% variance, respectively. SCR partially mediated the relation between DTM and CRP (indirect effect = 0.07, p = 0.002), suggesting that the agility of the supply chain magnifies the effectiveness of DTM. Monte Carlo analyses validated the robustness of the findings, with DTM and SCR cumulatively accounting for more than 75% variance in the sensitivity of reuse performance. This study concludes that upgrading digital maturity and responsiveness is a strategy for achieving long-lasting modular timber construction on a circular basis. This study provides novel empirical insights into the relation of digital transformation to the aims of a circular economy.
