Visualising the destruction, creation of an Atlanta landmark

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。

迄今为止，最大的项目是建造梅赛德斯 - 奔驰体育场，佐治亚圆顶的相关拆除以及Home Depot后院的建设。这样的巨大项目被委托给当地公司，这证明了亚特兰大社区对达登公司的信心。

记录最大覆盖的体育场之一

After the completion of Mercedes-Benz Stadium in Atlanta, Darden & Company was tasked with managing the implosion of the Georgia Dome — one of the largest covered stadiums ever built — and the subsequent construction of the recreation space that took its place. The firm discovered that Unmanned Aerial Vehicle (UAV) imagery and mapping services were just what was needed to keep the project on schedule and communicate with stakeholders from top to bottom.

The Georgia Dome was a70,000-seat stadium在亚特兰大。建造时，它是最大的

世界上有覆盖的体育场。圆顶是NFL亚特兰大猎鹰的家24 seasons, and in its time, it hosted more than1,400 eventsattended by more than37 million spectators。It was demolished in November 2017, after the completion of the Mercedes-Benz Stadium just83 feet（约25米）远。

The Home Depot Backyard is a44,515-square metre greenspace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。

佐治亚圆顶如何成为家得宝后院的故事是5,000 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 Gigabytes amount of data processed

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。

“The implosion was meticulously planned to avoid damage, but we wanted to make sure we had a lot of images of the World Congress Center and the new stadium to use as a resource in case anything unexpected happened,”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，您会得到很多碎片。删除所有瓦砾并为家得宝后院带来新材料是一个巨大的挑战 - 但Darden＆Company凭借其无与伦比的LargesCale项目管理经验，远远超出了准备。

Darden & Company used Multivista to文档使用U项目网站AV mapping。每周一次，多维斯塔飞行员将在网站上飞行无人机，收集视觉数据。该数据是通过高级摄影测量引擎处理的，以生成可以从多维斯塔平台内访问的地图。项目利益相关者能够注释地图，将其用于测量距离，体积，面积和高程，并将捕获的数据导出到create 3D models。

“We’d take last week’s aerial map, compare it side-by-side to this week’s map so we could tell the volume, size and scale of what had been removed in the past week,”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的航空图像和正摩萨图对于与希望在不必访问该网站的情况下保持进度的项目利益相关者的沟通非常宝贵。休斯描述了每周的校长会议，项目利益相关者将审查最新的无人机地图并讨论下一步。

“We were able to communicate progress internally and externally using aerial data. ‘Yes, we’re on top of it,’ ‘Yes we’re managing it,’ ‘Yes, they hit their dates - and here is how we can tell,’”said Hughes.

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。

“Mr. Blank loved seeing the aerial pictures with our 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 used Multivista for a wide range of services on the Georgia Dome implosion and The Home Depot Backyard, as well as the construction and facilities management of Mercedes-Benz Stadium.

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
• Video
• 实时流网络摄像头
• 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。“But because we were working on multiple projects, we knew we could use Multivista to manage the day-to-day activities. It was a pretty easy decision on the front end and we’ve definitely gotten our value out of it.”
