SUSTAINABLE DEVELOPMENT GOALS INTEGRATED INTO THE A+B BIDDING METHODS FOR THE ROADWAY PROJECTS

The highway construction industry has a favorable impact on traffic services when road operations and maintenance effectively provide convenience for users and society in terms of environmental life cycle sustainability. The project procurement process that leads to contract launch is an important part of the construction industry. Alternative contracting methods (ACMs) such as A+B bidding are relatively popular in reducing the duration of road projects, with the main purpose of reducing road user costs. To realize the Sustainable Development Goals (SDGs) launched by the United Nations (UN), the addition of SDG components should be recommended as an integrated part of determining the winning tender for roadway construction projects. This paper is the first to offer a theoretical concept to incorporate the relevant SDGs into ACM to regulate the contractor winning the tender for highway construction projects.
