Sustainable Infrastructure

O’Brien & Company is one of the Pacific Northwest’s only sustainability firms specializing in civil infrastructure projects, sustainability program development for infrastructure agencies, and community-wide sustainable infrastructure planning.We recognize that the planning, design, construction and operations of public infrastructure can significantly impact the sustainability of a region. Whether the project is a wastewater treatment plant, a light rail extension, or green stormwater infrastructure, an new level of collaboration with stakeholders; an understanding of the political and financial landscape shaping infrastructure investments; and a willingness to explore new approaches and strategies that are redefining our approach to infrastructure is required.


O’Brien & Company works closely with infrastructure project teams and owners to navigate the many decisions that will impact project performance and sustainability through all project phases. We apply our integrative process to infrastructure projects when possible to help teams keep sustainability embedded rather than layered on the increasingly complex range of goals and requirements that projects face. We bring knowledge of different infrastructure standards and frameworks to set performance goals, select appropriate strategies, and then help teams track against them. We also work with teams to develop custom performance frameworks and tracking systems at both project and agency/enterprise scales.
