“…This study found that the industry stakeholders rely on their expert opinions and past experiences to establish the life cycle assessment strategies for the alternatives, which specify the timing of rehabilitation, upgrading and reconstruction. An asset forecast life is a major influence on life cycle analysis (Santos and Ferreira 2013). An error in the forecast may cause a huge difference when predicting the costs for an asset such as highway infrastructure with a 50-60-year life span.…”

Highway construction works have significant bearings on all aspects of sustainability. With the increasing level of public awareness and government regulatory measures, the construction industry is experiencing a cultural shift to recognise, embrace and pursue sustainability. Stakeholders are now keen to identify sustainable alternatives and the financial implications of including them on a life cycle basis. They need tools that can aid the evaluation of investment options. To date, however, there have not been many financial assessments on the sustainability aspects of highway projects. This is because the existing life cycle costing analysis models tend to focus on economic issues alone and are not able to deal with sustainability factors. This paper provides insights into the current practice of life cycle cost analysis, and the identification and quantification of sustainability-related cost components in highway projects through literature review, questionnaire surveys and semi-structured interviews. The results can serve as a platform for highway project stakeholders to develop practical tools to evaluate highway investment decisions and reach an optimum balance between financial viability and sustainability deliverables.

“…The existing studies assumed that the roadway conditions and requirements would not change over the lifetime of a highway project. They were not concerned with the upgrading and end of life costs, which is obviously not reflecting real-world situations (Goh and Yang 2013;Ozcan-Deniz et al 2011;Santos and Ferreira 2013;Zhang et al 2010). …”

“…The multi-alternative orientation, accounting for other costs than only agency costs and sensitivity analyses have further been highlighted as integral parts of LCCA by Ozbay et al (2004). In Santos and Ferreira (2013), different pavement design alternatives were evaluated at project level in order to find an optimal design alternative depending on the road's traffic class. This was further analysed under different scenarios of varying discount rates .…”

In the past decades, many single carriageway roads in Sweden have been converted to collision-free roads as a cost-effective alternative to conventional motorways. Investigations have concluded that the road type has been successful in reducing the number of fatal accidents, despite increased operation and maintenance costs. In recent years, the focus has shifted to converting narrower roads, which are anticipated to further increase pavement rehabilitation cost but also complicate traffic management during road works. This paper first examines the consequences in terms of road agency and road user costs; second, the possibilities to influence future costs by design alternatives. A life cycle cost analysis was employed to study future costs. The analysis indicated significant increase in life cycle cost compared to a single carriageway road. The analysis of design alternatives also indicated that future agency and road user cost can be substantially improved by finding an optimal alternative.

“…It is widely used for industrial analysis such as water supply design, water treatment, and also for the assessment of rainwater control measures (Racoviceanu et al, 2007;Stokes and Horvath, 2009;Santos and Ferreira, 2013;Liao et al, 2014). The LCC calculation for BMP was generally the summation of initial and maintenance costs as figure up from the whole life cycle.…”

Diffuse pollution management in Korea initiated by the Ministry of Environment (MOE) resulted to the construction of pilot facilities termed Best Management Practices (BMPs). Twelve BMPs installed for the diffuse pollution management in the Kyung-An Stream were monitored since 2006. Data on the mass loading, removal efficiency, maintenance activities, etc. were gathered and utilized to conduct the evaluation of long-term performance of BMPs. The financial data such as actual construction, design and maintenance cost were also collected to evaluate the lifecycle cost (LCC) of BMPs. In this study, most of the maintenance activity was focused in the aesthetic maintenance that resulted to the annual maintenance cost of the four BMP types was closely similar ranging from 8,483 $/yr for retention pond to 8,888 $/yr infiltration system. The highest LCC were observed in constructed wetland ($418,324) while vegetated system had the lowest LCC ($210,418). LCC of BMPs was not so high as compared with the conventional treatment facility and sewage treatment plant. On the other hand, the relationship of removal efficiency on unit cost for TSS and TN was significant. This study will be used to design the cost effective BMP for diffuse pollution management and become models for LCC analysis.
