Visualising the destruction, creation of an Atlanta landmark

Author:Renata Barradas

团队在Darden & Company自1999年以来，一直在美国佐治亚州亚特兰大市管理LargesCale建设项目。其投资组合包括美国职业足球大联盟亚特兰大联合会的培训设施，Arthur M. Blank家庭办公室大楼和其他几家大型酒店，Condominium，Office，Office，Office和混合用途建筑物。

The biggest project to date was the construction of the Mercedes-Benz Stadium, the associated demolition of the Georgia Dome, and the construction of The Home Depot Backyard. That such an immense project was entrusted to a local firm is a testament to the confidence the Atlanta community has in Darden & Company.

Documenting one of the largest covered stadiums

在亚特兰大的梅赛德斯 - 奔驰体育场结束后，达登＆公司的任务是管理佐治亚州圆顶（有史以来最大的覆盖体体育场之一）的内爆 - 随后建造了娱乐场所。该公司发现，无人机（UAV）图像和映射服务是按计划保持项目并与从上到下与利益相关者进行沟通所需的。

佐治亚圆顶是70,000-seat stadiumin Atlanta. When it was built, it was the largest covered stadium in the world. The Dome was the home of the NFL’s Atlanta Falcons for24 seasons, and in its time, it hosted more than1,400 eventsattended by more than3700万观众。It was demolished in November 2017, after the completion of the Mercedes-Benz Stadium just83 feet(approximately 25 metres) away.

The Home Depot Backyard is a44,515平方米的绿色空间位于前佐治亚圆顶遗址。这是在猎鹰游戏之前尾门，看户外电影或参加社区节的理想场所。

The story of how the Georgia Dome became The Home Depot Backyard is the story of5,000 pounds(about 2,268 kilograms) of explosives, tons of debris, and nearly a year of hard work — and Multivista was there to document all of it.

Data generated included:

• 捕获的33,085张图像
• 70 Aerial flyover videos produced
• 535千兆字节处理的数据量

First challenge – Protecting the neighbours

The Georgia Dome was bordered by the Georgia World Congress Center to the north and the new Mercedes Benz Stadium to the south. One of the major considerations of the demolition was verifying these buildings weren’t damaged by the implosion.

项目管理公司Darden＆Company签订了协调和监督许多有助于拆除佐治亚州圆顶的球员和Home Depot后院的建设。Darden＆Company的团队聘请了Multivista，在拆除之前和之后，就捕获了相邻结构和圆顶本身的详细图像。

“爆炸是精心计划的，以避免损坏，但我们想确保我们有很多世界国会中心和新体育场的图像，以防万一发生任何意外发生的资源。”says Jason Hughes, senior vice president at Darden & Company.

Multivista used ground-based imagery and UAVs to visually document all three buildings just before and immediately following the implosion. Darden & Company shared access to all captured visual documentation with five partner firms for review and verification.

第二个挑战 - 跟踪材料去除

When you destroy a70,000-seat stadium, you get a lot of debris. Removing all that rubble and bringing in new materials for The Home Depot Backyard was a monumental challenge — but Darden & Company, with its unparalleled largescale project management experience, was more than ready.

Darden & Company used Multivista to使用无人机映射记录项目网站。Once a week, Multivista pilots would fly UAVs over the site, collecting visual data. That data was processed through an advanced photogrammetry engine to produce a map that could be accessed from within the Multivista platform. Project stakeholders were able to annotate the map, use it tomeasure distance, volume, area and elevation, and export the captured data tocreate 3D models。

“我们将拍摄上周的航空地图，将其并排与本周的地图进行比较，以便我们可以说出过去一周中删除的内容的数量，大小和规模，”休斯说。

“In the past, we may have said ‘Wow, it doesn’t look like that rubble pile’s moving.’ But that’s a subjective opinion and this was not. We took that out of the equation, which allowed us to be more proactive and knowledgeable about the project.”

Third challenge - Communicating with stakeholders

Multivista’s aerial images and orthomosaic maps were invaluable for communicating with project stakeholders who wanted to keep tabs on progress without having to visit the site. Hughes describes weekly principal’s meetings where project stakeholders would review the latest UAV map and discuss next steps.

“我们能够使用空中数据在内部和外部进行进度。‘是的，我们最重要的是，’“是的，我们正在管理它，”“是的，他们打了约会 - 这就是我们能说的，’”休斯说。

此外，航空影像原来是将最新消息发送给Home Depot的联合创始人，也是亚特兰大猎鹰队的所有者Arthur Blank的好方法。

”空白先生喜欢和o看到照片的天线ur weekly updates,”休斯说。“我们用它们来交流进度，因此他可以提出问题。没有比这些航空图像更好的通信工具。”

Visualisation takes many forms

Darden＆Company使用Multivista在佐治亚州圆顶内爆和家得宝后院以及梅赛德斯 - 奔驰体育场的建设和设施管理上提供了广泛的服务。

这些服务跨越了四年，包括现场调查，内部和外部进度，剪裁前，地下公用事业和MEP Exact-Built®文档，所有者培训视频以及现场流式网络摄像头。可交付的记录这一四年转型的交付物包括：

• UAV images
• UAV flyover videos
• Aerial mapping
• 照片
• 视频
• Live-stream webcam
• 网络摄像头的时间流失

“Originally, we were talking about putting up a webcam for the Falcons to use on the PR [Public Relations] side, just to give fans the latest and greatest,”休斯说。“但是，由于我们正在从事多个项目，因此我们知道我们可以使用多维斯塔来管理日常活动。在前端这是一个非常简单的决定，我们肯定已经从中获得了价值。”

The Home Depot Backyard opened to the public, on time, in September 2018.
