2021年6月杂志-古城天幕,世界最大的数字标牌

2021-06-30

Las Vegas’ historic downtown is home to an unbelievably immersive video experience, built around the largest single video screen in the world. Each year, millions of people visit this four-block pedestrian mall to shop, enjoy concerts, ride the zipline – and witness the stunning digital light shows overhead.

拉斯维加斯历史悠久的市中心,拥有令人难以置信的身临其境的视觉体验——古城天幕。这一切都围绕着世界上最大的单个数字标牌构建而成。以后的每年里,成千上万的游客都能在这个由四个街区组成的步行街里购物、欣赏音乐会、乘坐观光索道——然后目睹着头顶上华丽的数字灯光秀而惊叫连连。

Federal Heath was selected to install a total digital canopy upgrade in 2019. The installation required working high above the ground to fit custom-built panels into tight spaces, adjacent to dense pedestrian traffic and ongoing public events.

联邦希思在2019年被选中为费利蒙大街整体进行升级,安装数字标牌天幕。这项安装任务需要在地面之上进行高空作业,将定制的数字标牌面板安装在狭窄的空间中,毗邻下方密集的人流和正在进行中的公共活动。

Highlights

» Installation 90 feet above a pedestrian mall

» Working around visitors, events and a zipline

» 1,000+ custom-fit panels, each 6 x 24 feet

» Total canopy 4 city blocks long

重点

» 人行道上方27m处的安装工作

»协调下方的游客、活动和观光索道

» 整个数字标牌由1000多块定制面板组成,每块尺寸为1.8m*7.3m

» 整个古城天幕覆盖了4个街区

Scope目标

It’s one thing to see flat digital displays in large formats – on scoreboards or even buildings. But imagine such displays replacing the sky above four city blocks. Imagine them configured as a curved barrel vault canopy. Now you have Fremont Street Experience, nearly 3 acres of contiguous digital pixels arching 90 feet above the ground.

在计分板或者建筑物上看到超大尺寸的平面数字标牌是一回事,而费利蒙大街为人们带来的又是另外一种震撼的感觉——想象一下这样的数字标牌:它被定制为弯曲的拱形穹顶天幕,取代了整整四个街区上方的天空。

这就是费利蒙大街的古城天幕:连续的数字影像在离地27m的空中呈拱形,把将近1.2公顷的区域环绕包围。

The original Viva Vision canopy was created in 1995 with incandescent bulbs. Advances in LED technology made upgrades possible in 2004 and again in 2019. Most recently, more than 1,000 panels were custom manufactured by Watchfire Signs and installed by Federal Heath in time to welcome the 2020 New Year.

费利蒙大街早在1995年就开始采用顶篷包围的设计,最初的Viva Vision顶篷采用白炽灯泡制作,古城天幕之称也正是从那时开始出现。在LED技术的不断进步下,分别在2004年和2019年进行相关的升级。最近的这次升级,是Watchfire标识为其定制了1000多块面板,由联邦希思公司适时安装,以迎接2020新年的到来。

Challenges挑战

Fremont Street Experience attracts millions of visitors each year, a bustling business of daily commerce and special events that continued in full swing during our six months of installation. Working during off-peak hours helped, but we were still responsible for maintaining a safe environment for 24/7 pedestrian traffic from move-in to move-out.

古城天幕景观每年能够吸引数百万游客,天幕之下,不论是日常的商业活动还是举办特别活动,都异常的繁忙。在联邦希思长达六个月的安装过程中,整条费利蒙大街更是如火如荼。虽然联邦希思选择在非高峰时间进行工作的计划有所作用,但他们仍然在施工区域的下方维护出一个安全环境,以保障费利蒙大街每天24小时的人员进出。

Just moving equipment, tools or materials between the yard and job site was a big job, one reason we chose to compress the work into four long days each week when possible. The heat was another challenge for crews who were working in direct sunlight far above the ground.

由于费利蒙大街是商业场所,没有充足的停放空间,因此必须在租用的存储场地和工作地点之间来回移动设备、工具和材料,这让安装工作变得非常艰巨,因此联邦希思公司选择在保障工程如期交付的情况下每周将工作时间压缩在四整天。另外,拉斯维加斯炎热的天气对于在高空中直面阳光的工作人员来说,也是一个巨大的挑战。

The space between the canopy and ground was cluttered with obstacles to work around, including a zipline, speakers and the “finger” structures that topped off 16 supporting columns.

不仅是地面的繁忙,在顶篷和地面之间的空间也杂乱无章,为施工增加了难度,包括观光索道、大喇叭和多达16个“手指”结构支撑柱。

Process

过程

The yard. Workdays started about midnight at a yard several blocks from Fremont Street Experience, where equipment, tools, and the massive digital panels were stored. Panel shipments were timed to bring inventory at the right time, in the right order. Each day ended with hauling off old panels and empty crates from the yard shortly before noon.

临时租用的存储场地。安装团队每天的工作开始于距离费利蒙大街数个街区外的场地,哪里存储了设备、工具和庞大的数字标牌面板。由于这个临时场地存储空间比较有限,因此需要按照正确的顺序、正确的时间安排装运,带来库存。每天中午,团队回到场地,以拖走旧面板和空箱子结束工作。

The setup. The caravan of trucks, lifts, crane, trailers, and crews going to and from the job site was quite a sight. At the job site, we began by outfitting heavy equipment with protective boots and marking off the work area from tourists. One of our senior project managers oversaw work progress in person.

配置。往返于存储场地与费利蒙大街工作现场的卡车、升降机、起重机、拖车和团队专乘的大篷车非常引人注目。因此在工作现场,联邦希思首先为重型设备配备防护靴,并从游客通道划出工作区域。为此,联邦希思专门派遣以为高级项目经理亲自监督这些工作的进度。

The basics. Just getting crews into the canopy infrastructure was painstaking – a half hour to ride the lift, climb into position across 3-inch tubes, and tie off for safety. Old panels were unbolted and dropped down by hoist as ground crews prepared new ones to be lifted.

基础工作。不提后面的安装工作,仅仅是让工作人员进入顶篷的结构内就是一件艰苦的工作:首先乘坐半小时电梯,从间隔7.6cm的管道爬到工作位置,然后系好安全绳。这时地勤人员准备着将新面板吊起,旧的面板解除固定螺栓并用电梯运送至地面。

The details. Each panel required its own combination of hoist and sheaves to properly lift it past aerial obstructions and maneuver it into position. One installation crew handled precise fitting around the supportive “finger” structures while another handled the broader canopy work, all subject to daily quality inspections.

Working from one end of the street to the other,

we replaced 1,054 panels one by one.

细节。由于每块面板形状不一,都需要使用独特的升降机和滑轮组合,以帮助其顺利通过半空中的障碍物,然后操纵安装到位。一名经验老道的安装人员处理支撑柱上“手指”结构周围的精确装配,另一名人员处理其他区域的大范围顶篷装配,所有这些工作均需要接受日常质量检查。

从费利蒙大街的一端至另一端,联邦希思一共替换了1054块面板。

Outcome结果

The newest Viva Vision is equipped with

4.9 million LEDs, creating a 16.3 million pixel display that covers 130,000 square feet. The finished product is seven times brighter and four times sharper than the previous version, making it vivid even during daylight hours.

最新的古城天幕总共使用了490万个LED,创造出1630万像素的超清数字标牌,总面积达1.2公顷。新的天幕比之前亮度提高7倍,清晰度提高4倍,即使在白天也能保持鲜艳。

The barrel vault design is unique, covering the sky above the lengthy pedestrian mall with unlimited opportunities for light- enabled experiences that draw visitors from far and wide. Content is controlled by centralized software.

天幕的拱形设计更是别具一格,它完全覆盖了漫长的步行街上方的天空,以近乎无限的方式提供灯光效果,牢牢地抓住来自远方的游客们的注意力。数字标牌的内容由集成式软件统一控制。

The unique scope and nature of this job has given it a special place in the history of Federal Heath – and certainly in the future travels of millions to Fremont Street Experience.

费利蒙大街古城天幕项目的独特目标和性质使得它在联邦希思的项目史中占有特殊的地位,而在未来数以百万计前往拉斯维加斯费利蒙街道的游客的旅行史中,也必将如此。
