吉尔伯特·阿什（Gilbert-Ash）在英国外国和英联邦办公室的Mayhew剧院

吉尔伯特·阿什是一家屡获殊荣的英国建筑公司，已完成高调和享有声望的建筑项目，从酒店和办公室到外国大使馆和领事馆，在30年中，在40个国家 /地区。在伦敦和贝尔法斯特的办事处，由于其专业知识和高质量的建设，他们经常被英国外国和英联邦办公室签约。他们最近构建了Diplomatic Teaching Academyin the Foreign & Commonwealth Office in London,威廉王子正式开放.

外交教学学院，正式被称为Mayhew Theatre之后，英国的第一位女性外交官Cecily Mayhew是抛物线玻璃，钢和木结构，必须在伦敦英国外国和英联邦办公室的庭院中建造。这意味着，钢制上层建筑需要由起重机将其提升到距离道路通道90米的庭院，任何一侧只有5米的间隙，这是一个非常微妙的操作。

For this project, Gilbert-Ash needed to operate within tight and sensitive spaces. They also had to complete an intricate and highly modern building with very strict geometrical design specifications. Fortunately, they invested in theLeica BLK360imaging laser scanner, a crucial piece of technology that helped them achieve success with the Mayhew Theatre, which won a2019 Construction Excellence Award.

复杂，备受瞩目的建筑所需的先进技术

吉尔伯特·阿什, as indicated by their successful record, has always been up to the challenges of high-profile construction work. However, the Mayhew Theatre design and construction process required advanced technology due to the complex challenges noted above.

“建筑物的上层建筑是一个悬臂双曲抛物面顶部环横梁带有锌屋顶 - 由于其形状而被称为pringle-在建筑物内，您有一个椭圆形的抛物面雪松板板天花板。对于非架构，高度几何语言表明这是一个复杂的结构。

是的，Pringles是双曲线抛物面形的薯片。为了了解“双曲线抛物面”的复杂性，《纽约时报》发表了一篇文章关于超级计算机和提到的Pringles，特别是它们是如何设计的：“ Procter＆Gamble甚至使用超级计算机来确保pringles不破裂而进入罐头。”

显然，Mayhew剧院是一个复杂的结构，在设计和构造的每个阶段都需要无可挑剔的精度，而双曲线抛物面锌屋顶，与适合罐子的pring脚无不同，不需要适合庭院，而不会损害外国和联邦政府。办公室，列出的1年级遗产大楼。如果Pringles要求超级计算机适合罐头，那么Gilbert-Ash肯定需要BLK360才能成功建造Mayhew剧院。

Gilbert-Ash在Leica BLK360上投资以创建3D模型

At the start of the project, McGeachy and Graeme Gourley, Senior Estimator, realized that they needed to have extremely precise measurements of their construction plans for the theatre. They had already had some experience with digital construction and reality capture tools, but McGeachy came across the BLK360 and thought it might be the right fit for their portfolio of technology.

“I was at a digital construction fair, checking out the different stalls, and I came across the Leica stand. A spokesman talked me through it and gave me a demonstration,” said McGeachy. “At that point, it was easy to identify that this would be a good addition to our digital construction tools.”

However, because of the space constraints of the job site, the complicated design, and work with subcontractors, it wasn’t possible to simply start work there and adapt the design as work progresses. Instead, Gilbert-Ash decided to start building the steel superstructure off-site in order to determine on-site dimensions.

“必须通过使用数字构造方法对所有情况进行精心思考，”
said Gourley. “We pre-erected the theatre to determine the size of the glass before it was manufactured and sent to site.”

McGeachy说：“对于我们来说，在现场设定维度，我们可以看到的唯一方法就是以3D捕获它。”然后，他们使用BLK360扫描上层建筑并确定精确的尺寸，然后可以将其用于订购其他材料，例如玻璃和木材组件。BLK360捕获的准确点云数据使Gourley的团队能够精确地开始他们的整个设计过程，从而有助于确保在施工的每一步中的准确性。

“We’re one of the first people in Northern Ireland to invest in the Leica BLK360. We use that to capture our 3D point cloud data,” said McGeachy. “With the 3D models we had developed, we could easily identify clashes between all three disciplines and hold workshops with sub-contractors to develop methods for changes to the design.”

捕获上层建筑后，McGeachy使用了几个工作流来处理数据并使用Autodesk Revit，Recap Pro＆Mobile以及NavisWorks创建3D模型。然后，他能够开发现有的Revit模型和尺寸的AutoCAD图纸，钢铁分包商能够使用Tekla结构软件成功设计钢结构，框架和连接。

McGeachy说：“您拥有这些非常复杂的几何形状，并且在这种设计中依靠和互动时，它使其变得更加复杂。”由于剧院设计中的材料和形状各不相同，吉尔伯特·阿什（Gilbert-Ash）依靠BLK360的基本数据来告知确保成功完成Mayhew剧院所需的所有3D建模。

“The Leica BLK360 has basically transformed the way we complete our projects, and it’s made a huge difference to us, especially with the coordination of subcontractors,” said Gourley. “Design clashes can be identified earlier, and the client can get a better sense of what they’re getting earlier on in the project."

由于如此复杂的结构是为如此突出的地点，目的和客户而建造的，因此BLK360帮助吉尔伯特·阿什（Gilbert-Ash）继续与英国外国和英联邦办公室的成功关系和屡获殊荣的工作。我们期待看到Gilbert-Ash如何将3D激光扫描纳入他们的未来项目。
