“…The Timber is at the forefront in terms of resistance to weather conditions and chemicals. The service life of timber poles used in telecommunication lines and timber road bridges is 50 years [17]. The life of concrete, steel, and PVC can reach half the life of the Timber.…”

Wood is a natural resource that is renewable, easily recoverable and stores carbon dioxide, making wood constructions a feasible alternative to attaining significant sustainability targets. In the '90s, technological attendees invented the laminated wood beams, and it begins to apply the ingenious truss solved principle to the building structures of laminated and plywood. A new generation hybrid construction method dubbed the Urban Timber (UT) System was designed to support the timber buildings based on the diagnostic vulnerabilities of wooden structures. The system was defined and demonstrated while taking into account structural behavior, architectural value. Everything else is left to the designer's discretion, his sensitivity, and, above all, his ability to leverage technology from the many advantages and many-sided. The research seeks to inform future generations about the predicted sustainable features of wooden structures, which are touchstones of the global construction industry, under the usual circumstances of a new industry. To that end, it has proven why industrialized timber building systems are a fundamental problem in the context of the present environmental, social, and psychological discussion and the utilization of distinct construction approaches using sustainable materials. Timber is seen as the future building material, according to the findings.

“…LCA concentrates on environmental aspects-resource use, ecological consequences and human health-and does not normally address economic or most social aspects (Klöpffer and Grahl, 2009). Rodrigues et al (2017) presented an application to evaluate the environmental friendliness of TCC bridges with respect to traditional solutions. Pang et al (2015), Penadés-Plà et al 2016, and Dabous et al (2017) presented comparative LCA analyses between alternative bridge maintenance scenarios.…”

The present study provides a review of the most diffused technical and non-technical performance indicators adopted worldwide by infrastructure owners. This work, developed within the European COST Action TU 1406-"Quality specifications for roadway bridges, standardization at a European level," aims to summarize the state-of-art maintenance scheduling practices adopted by bridge owners, mainly focusing on the identification and classification of the most diffused performance indicators (PIs). PIs are subdivided in technical and non-technical ones: for this latter subclass, PIs are classified in environmental, social and economic-targeted. The study aims to be a reference for researchers dealing with performance-based assessments and bridge maintenance and management practices.

“…Due to its low environmental impacts, timber is becoming more and more used for the construction of new infrastructure [39][40][41]. However, the durability of unprotected timber structures may have durability issues and requires specific design concepts and treatment to have a long service duration [42,43].…”

Ultra-High-Performance Fibre-Reinforced Cementitious Composite (UHPFRC) has been developed to design lightweight structures and enhance existing designs. As the environmental footprint of the construction industry must be significantly reduced, the potential to lower environmental impacts of structures using UHPFRC needs to be explored. While the greenhouse gas emissions of a volume of UHPFRC are higher than that of the same volume of concrete, UHPFRC enables the reduction in the amount of material required in structural designs and improves the durability of structures. The environmental impacts of structural designs must thus be compared on the cradle-to-grave use cycle of the design at a project scale. In this study, a methodology is proposed to evaluate the ecological burdens of several bridge designs involving various structural elements in UHPFRC. The method proposes an analysis over three time horizons: first, the construction phase, then including the scheduled maintenance, and finally, adding the elimination. A case study of a short-span bridge in Switzerland is used to assess three alternatives of bridge designs: a conventional reinforced-concrete structure, a composite timber–UHPFRC bridge, and a full-UHPFRC solution. The results show that timber–UHPFRC structures can significantly reduce the environmental impacts of bridge designs, showing promising results in terms of sustainable development. The use of the methodology supports bridge owners in assessing the environmental impacts of structural designs.
