SSS.infra Guideline: a new quantitative tool for the performance assessment of civil infrastructure

The function of all infrastructure in organised societies, is to provide for personal security, establish a basis for public health and institutionalise a quality of life equal to the expectations of those it serves. That’s why many accredited rating systems are currently available on the market to assess sustainability of both buildings and infrastructural works. Unfortunately, these protocols are mainly based on a qualitative approach, being difficult to implement in everyday design practice.

Considering this fact, SSS.infra Guideline has been developed to overtake subjectivity, endorsing a rational evaluation of the achieved performance and promoting a holistic and design oriented technical approach. The aim of this paper is to present the Guideline, showing how sustainability goals can be reached through conventional design stages and presenting the findings of a meaningful pilot project, the Tehran-Shomal Freeway).
