My favorite shows to watch on television are home renovation programs. You know the shows where a young family buys the worst house on the block and the entire episode features them turning this house into their dream home? Most of these episodes are highly dramatic. The couples is in the middle of renovating and find out that they don’t have the proper permits or they start opening the walls and find surprises like bad wiring, leaking plumbing, or asbestos. Because of these issues they are now overbudget, delayed, and now must live in their parent’s basement for another couple of months!

I think one of the reasons why I enjoy watching these types of shows is that they mirror (on a much smaller scale), what can happen on a transportation construction project without proper planning related to environmental compliance. Maintaining environmental compliance during transportation construction projects hinges greatly on a consultant’s knowledge of an expansive number of items such as the contracting mechanisms used, permitting and related impacts to stormwater and natural resources, and handling surprises like hazardous materials.

传统设计/出价/构建与替代交付

在评估与运输项目建设有关的环境规范风险时，采用的收缩方法的类型在评估与建设相关的环境依从性风险时起到重要因素。在传统的设计/出价/构建方案中，项目所有者的目标是概述并指定项目的所有环境要求，以获得最具竞争力的竞标情况。从环境的角度来看，这些项目是公正的规范性的，项目所有者通常负责实现该项目的环境遵从性，减少承包商的风险。在这种类型的交付方法中，由于承包商可以在规范中没有具体概述的环境合规问题要求赔偿赔偿，因此在项目所有者的最佳兴趣。

In an alternative delivery scenario, such as design/build, environmental compliance is almost entirely borne by the design/build contracting team (i.e., the contractor). Within the request for proposal documents, the project owner merely provides an outline of the project’s environmental requirements and allows the design/build team to find innovative ways to mitigate environmental impacts. This can be done either by modifying the overall design via the alternative technical concepts (ATC) process, such as building a bridge over a wetland versus constructing a road. Also, construction practices can be altered to mitigate environmental impacts such as using cranes on barges for river bridge erection rather than building a causeway. When environmental experts are an integral part of the design/build team, project costs and risks are reduced benefitting both the owner and the design/build contractor.

雨水污染预防允许和实践

与任何建设项目一样，雨水污染预防实践(SWPPP或SWP3)成为关键在ea的发病rthwork activities. For transportation projects, erosion and sediment control can be challenging often due to the linear nature and sheer scale of the project. For example, reconstruction of a roadway through a densely populated urban area often doesn’t allow room for temporary sediment control basins. When a heavy rainfall results in a wet, messy grade or small swimming pools in utility trenches, it can be tempting to directly pump the water into the adjacent storm sewer resulting in something resembling chocolate milk entering into the closest water body. This is a finable offense under National Pollution Discharge Elimination System (NPDES) permit requirements. Not to mention that this would definitely be frowned upon by the multiple soil and water conversation districts and public MS4 entities that are watching this project. A more creative and environmentally compliant solution can include the use of large weir tanks, that “follow” earthwork activities, to store accumulated rainwater and allow for treatment using flocculant, so that turbid-free water can be discharged directly in the storm sewer network.

自然资源

除了雨水之外，建造运输项目时还有许多自然资源考虑因素。最值得注意的考虑之一，因为它通常是交通工程，特别是桥梁项目，正在努力和毗邻水体。水上和周围的建筑需要额外的允许，并且必须确保水不会影响溢出，从桥梁拆除，混凝土冲洗和疏浚的碎片。

有害物质

Another less commonly understood environmental compliance issue what to do when hazardous materials are unearthed during construction. This is a particular issue on transportation projects that travel through urban areas where adjacent property uses (like gas stations, dry cleaners, industrial facilities) have impacted the underlying soil and groundwater and migrates into the project area. Encountering surprises like stinky soils, groundwater with a rainbow sheen, asbestos containing materials, or debris may represent significant handling and disposal costs that will almost always adversely impact schedule and project cost. A properly completedPhase IEnvironmental Site Assessment (ESA) and第二阶段ESA可以帮助施工之前识别潜在的惊喜，以便可以制定和实施补救和应急计划。
