What Does Sustainable Infrastructure Look Like? 百乐博app|PCL 水 Team Has Solid Answers

Earth Day is here, 从国会大厅到美国各地的州和市机构, 有很多百乐博app基础设施支出和可持续性的讨论. 可持续建设和重建基础设施的实际工作, 然而, has seen less attention. Environmentally speaking, 建筑的碳足迹和垃圾填埋都不是小事, 这个话题通常都是围绕已使用建筑的LEED标准展开的. But what about projects like bridges, flood control structures, light rails, and water treatment plants?

In Salt Lake City, 犹他州, 百乐博app|PCL正在重建一个每天4800万加仑的水回收设施(WRF). The five-year, 5.28亿美元的项目旨在为WRF校园获得设想白金,为其新行政大楼获得LEED金.

设想, 一个可持续性评级系统在业内迅速普及, is designed to help project owners, designers, 而承包商则尽可能地创造最可持续、最具弹性的基础设施. In Salt Lake City, 犹他州, 百乐博app and joint-venture partner PCL Construction are rebuilding a 48-million-gallon per day water reclamation facility (WRF) with a verification goal of 设想 Platinum. According to Sr. Project Engineer Jenn Graves and Sr. 项目经理James Atkins表示,实现这一目标的过程需要承诺和协作.

A City with a Vision, a Project with a 目的

In 2017, 当时的市长杰基·比斯库普斯基签署了一项行政命令,呼吁全市在可持续发展方面进行合作, 包括朝向净零建筑和可持续基础设施的发展. The city chose to pilot 设想 for the new WRF, 既要收获可持续的利益,也要看看该框架如何应用于未来的市政项目. 到目前为止,该项目正逐渐成为一个有前途的案例研究.

自11月以来,WRF的土方工作人员已经安置了近1个.500万吨预压材料,解决长期地面沉降. 使用预压桩而不是100%打桩的决定为纳税人节省了大约4000万美元.

作为盐湖城唯一的水处理厂,新的WRF需要做好几件事. 更换一个有55年历史的工厂,使其符合未来EPA法规的要求,这仅仅是个开始. There are 64 possible credits in 设想, 从保护土壤健康到评估长期维护成本, to reducing air pollution, to using recycled materials. 这看起来好像有很多事情需要关注——而且确实如此. But to PCL’s James Atkins, 这归根结底是我们团队的承诺:我们在这里是环境和资源托付给我们的好管家.

All of us—owner, designer and contractor—live and work in these communities, 我们想成为环境最好的管理者. 展望会帮助我们建立新的基础设施. 我们正在减少碳足迹,并在前进的过程中收集所有这些数据和新知识.

Collaboration is a Do-or-Die, not a Nice-to-Have

获得愿景验证要求项目达到所有可应用愿景点的最低百分比.  铂金认知度占总分的50%,说起来容易做起来难. “Part of the challenge is that some credits are builder-only, some fall to the designer, some to the owner, some to the plant staff, and some to all four,” said 百乐博app’s Jenn Graves. 所以,我们真的需要让每个人都达成一致,否则,我们就会错过关键的对话.”

挖掘机操作员将拆除的混凝土从钢筋中分离出来, 留下了像巨大的金属风滚草一样的东西在路边的回收场被回收. From here, 现场破碎允许百乐博app|PCL有效地重新利用整个项目的材料, 避免了把它们拖到垃圾填埋场和拖进新材料来做同样的工作的费用和排放.

Jenn和James都指出,项目交付方法对于早期建立高度协作至关重要. “Using the old-school approach of design-bid-build, 要达到我们所要达到的核查水平将会困难得多,” said James. Since this is a construction manager at risk (CMAR) project, 百乐博app|PCL was involved in the project’s early phases. “As we worked through different design conflicts, 各方的人们已经找到了使事情更可持续发展的方法.”

采用基于团队的方法的另一个原因是,我们的设想计划是一个实时文档. Over the course of a five-year project, things are bound to change, 团队成员有一长串的责任要处理. According to Jenn, 在项目进行的同时调整计划是需要接受的,而且很多已经接受了.

那么多不同的范围、交易和数量都在不断地变化. 您需要整个站点的领导者承担跟踪这些数据的所有权. We already have that kind of culture here. 我们的一个现场主管甚至创建了他自己的二维码系统来跟踪我们的建筑用水量. 这种水平的团队合作——以及由此产生的想法——使我们更加可持续发展.

其中一点类别,将决定百乐博app|PCL的成功实现预想白金是资源分配. In this area, we’ve committed to recycling, reusing and/or salvaging at least 50% of all waste materials. 如下图所示,该项目目前远远高于这一标志.

对Jenn和James来说,这些结果都很惊人,但并不令人惊讶. 它们是项目团队努力使可持续发展真正成为优先事项的结果. “With anything new that comes out in this industry, people tend to think, ‘Why would I want to be involved with that? My job is difficult enough,'” said James. “But with these efforts, which Jenn has really spearheaded, 人们对可持续建设的重要性的态度正在转变. 从长远来看,业主和社区将从中受益.”
