The Georgia Department of Transportation (GDOT) implemented a programmatic agreement as green tape to streamline environmental review and decrease project durations. We investigate the implementation and outcomes associated with this streamlining initiative to examine whether it functions as green tape and investigate whether it improves performance by reducing project durations. We use a mixed-methods approach, using qualitative analysis to explore green tape perceptions of project team members and a quasi-experimental, instrumental variable approach to estimate the time-savings the created for a sample of 397 infrastructure projects. Our results reveal the streamlining initiative operates as green tape and demonstrate the substantial performance gains green tape can yield. These findings suggest that streamlining one project discipline impacts performance across the entire project, creating substantial time savings. Furthermore, they demonstrate how green tape functions in diverse project teams and can be applied in public agencies to create performance gains in infrastructure project delivery.

佐治亚州交通部 (GDOT) 实施了一项计划协议作为绿带，以简化环境审查并缩短项目持续时间。我们调查了与此精简计划相关的实施和结果，以检查它是否起到绿带的作用，并调查它是否通过减少项目持续时间来提高绩效。我们使用混合方法，使用定性分析来探索项目团队成员对绿皮条的看法，并使用准实验、工具变量方法来估计为 397 个基础设施项目样本创建的时间节省。我们的结果表明，精简计划作为绿带运行，并证明绿带可以产生显着的性能提升。这些发现表明，精简一个项目学科会影响整个项目的绩效，从而节省大量时间。此外，他们展示了绿带如何在不同的项目团队中发挥作用，以及如何应用于公共机构以提高基础设施项目交付的绩效。
