Managing cost implications for highway infrastructure sustainability
Goh, K.C. & Yang, J.
Abstract
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.
