“…More recently, researchers have attempted to include environmental costs in LCCA to consider bridge structure sustainability (Geryasio and da Silva 2008; Kendall et al 2008). LCCA has also been performed on pre-cast composite bridge decks (Hastak et al 2003;Ehlen and Marshall 1996;Ehlen 1999;Meiarashi et al 2002;Nystrom et al 2003;Chandler 2004). Additional work on LCCA was conducted that emphasized inclusion of cost, deterioration, and load uncertainties (Frangopol et al 2001;Thoft-Christensen 2009;Daigle and Lounis 2006;Furuta et al 2006).…”

A life cycle cost analysis (LCCA) was conducted on prestressed concrete bridges using carbon fiber reinforced polymer (CFRP) bars and strands. Traditional reinforcement materials of uncoated steel with cathodic protection and epoxy-coated steel were also considered for comparison. A series of deterministic LCCAs were first conducted to identify a range of expected cost outcomes for different bridge spans and traffic volumes. Then, a probabilistic LCCA was conducted on selected structures that included activity timing and cost random variables. It was found that although more expensive initially, the use of CFRP reinforcement has the potential to achieve significant reductions in life cycle cost, having a 95% probability to be the least expensive alternative beginning at year 23-77 after initial construction, depending on the bridge case considered. In terms of life cycle cost, the most effective use of CFRP reinforcement was found to be for an AASHTO beam bridge in a high traffic volume area.

“…For instance, Ravirala and Grivas looked at determining life cycle costs for highway management and included traditional agency costs, such as construction and traffic control, as well as user delay costscosts incurred by those waiting in construction traffic [29]. Ehlen has conducted several studies that look to expand the definition of life-cycle costing even further by recognizing costs due to environmental effects and those inflicted upon businesses affected by construction [30,31]. While Ehlen notes the importance of such externality costs, his studies do not account for them in calculating life-cycle costs.…”

Guiding the design and application of new materials for enhancing sustainability performance: Framework and infrastructure application

et al. 2005

This paper presents a framework for guiding the design of new materials to enhance the sustainability of systems that utilize these materials throughout their production, use and retirement. Traditionally, materials engineering has focused on the interplay between material microstructure, physical properties, processing, and performance. Environmental impacts related to the system's life cycle are not well integrated into the materials engineering process. To address this shortcoming, a new methodology has been developed that incorporates social, economic, and environmental indicators -the three dimensions of sustainability. The proposed framework accomplishes this task and provides a critical tool for use across a broad class of materials and applications. Material properties strongly shape and control sustainability performance throughout each life cycle stage including materials production, manufacturing, use and end-of-life management. Key material parameters that influence life cycle energy, emissions, and costs are highlighted. The proposed framework is demonstrated in the design of engineered cementitious composites, which are materials being developed for civil infrastructure applications including bridges, roads, pipe and buildings. This research is part of an NSF MUSES

“…Many researchers have developed life-cycle costing methods for roads materials [1] , highways, and infrastructure systems. Ehlen [ 2 ] identitied life-cycle costs for polymer-reinforced concrete bridges that include agency and user costs (driver delay, vehicle operating, and vehicle accident costs) and third party costs. Meng ling and Sun linying [3] conduct LCCA model in the study of energy-efficient buildings and come up with closure mana�ement strategies.…”

With the acceleration of urbanization process and the booms in domestic infrastructure investment, the amount of civil engineering projects and infrastructures increase with years. In this context, how to lower the energy and environmental impacts of proposed project while achieving an optimization of owner's investment capitals has become a research focus with both theoretical and practical significance. Since the traditional decision-making process of construction projects solely focuses on the return of investment, this research aims to formulize a more scientific one by combining the concrete economic costs with quantitative social costs. Specific methods adopted are life cycle costs analysis and hybrid life-cycle assessment. Result shows that the large-scale hydropower project, no matter in the aspect of life-cycle costs or in energy efficiency and environmental impact, are superior to the small-scale one.
