Sustainable Performance Evaluation of a Remediated Oil Field Using Envision™

摘要

This paper summarizes a study piloted by the Port of Long Beach (Port) that investigated the Envision™ 2.0 rating system to understand how it applies to port infrastructure projects. The study evaluated the sustainable performance of a past project, completed in 2009, in which an active oil field facility underwent site remediation before Envision became available. After review of all pertinent and available project documentation, a team of Envision Sustainability Professionals rated the project in accordance with the Envision 2.0 guidance manual. The project was evaluated in two ways: the first evaluated the as-built condition, and the second was a hypothetical evaluation that assumed the project team was able to use Envision at the planning stages of the project. Several simple yet high-impact actions were identified that could have improved the project's sustainable performance as indicated by the Envision rating. The Port used the study to evaluate available rating systems, including the Port's own sustainable infrastructure guidelines, to objectively support and demonstrate commitment to sustainable development and operations. Guided by its Green Port Policy that showcases sustainability as one of five guiding principles, the Port's Bureau of Engineering is incorporating principles of sustainable development into its routine project delivery procedures. An appropriate rating system can demonstrate and provide an objective measure of progress against this stated goal. Lessons learned are provided to help the project manager develop more sustainable projects using the Envision guidance manual.
