Towards Project Portfolio Management for Sustainable Outcomes in the Construction Industry

It is imperative that organisations improve their sustainability and there is a global push to reduce the environmental impact from project activities. This is especially true in construction, yet there is no ex1stmg framework to guide decision making and project portfolio management (PPM) for sustainable construction. This paper discusses the application of project portfolio management to the area of sustainable development in the construction industry. Using the understanding gained from existing PPM practices in a range of industries and the current approaches to risk and sustainability management in the construction industry, we propose a new maturity model for PPM. The maturity model aims to guide the introduction of sustainability factors into multi-project resource scheduling and risk analysis in the coustruction industry, and can be used to make the contribution to sustainability from an overall portfolio more sustainable than the sum of the contribution from individual projects, 1
