Scans, spans and automobiles

作者：克里斯托弗·多拉德（Christopher Dollard）

As part of Northern Ireland’s ‘Building a Better Future’ strategy to make it a better place to ‘live, work, learn and grow’, Amey Roads NI (ARNI) was tasked with building, operating and delivering improvements to a strategic road network across Northern Ireland (DBFO Package 2). But managing such a复杂的基础架构有挑战 - 从昂贵的道路封锁到解释1960年代的手绘。阿尼（Arni）的工作切断了，所以它转向了最新的现实捕获亚博ag真人规律技术,Leica BLK360，创建准确的3D point clouds和项目的图像。

The complexity of road infrastructure management

ARNI is responsible for高速公路和行李箱路540泳道,140个桥梁和ancillary structures. The company employs Amey Consulting to manage the lifecycle risk profile of new and existing highway assets, and tocomplete surveys of the bridges再保险计划必不可少的pair and improvement works, and as part of a regular inspection programme. All while keeping roads open and structures operational at all times – no mean feat. Any road closures would not only cost the company money but also take a lot of lengthy planning, not to mention disrupt traffic flow.

The BLK360 imaging laser scanner was designed to specifically address challenges like this. ARNI acquired a BLK360 and started to调查桥梁，创建参考模型和精确的3D扫描to support remedial work and regular safety inspections. Using the intuitive laser scanner and its iPad software, Recap Pro,调查桥梁成为一个更简单的过程. A single worker can park safely on the hard shoulder of the motorway and, at thepress of a button，扫描桥梁的整个底面，确保详细的360度,HDR spherical imagery and accurate point cloudsin minutes.

扫描提供3D point clouds, images of the bridges and its surroundings, and scan annotations highlight concrete delamination and exposed reinforcement. This helps to快速确定缺陷的确切位置和性质or areas of disrepair, rather than needing to解释站点笔记,sketches和图片. Design teams use the point cloud in Civil 3D to创建表面,elevation和section drawings, and plan repair works - including what parts, materials and resources are required - more efficiently. Once repair works are complete, a repeat scan can generate a complete as-built record for the health and safety file and can be used to substantiate the completion of works and authorise payments.

No turning back

Using the BLK360, ARNI can now carry out timely and accurate surveys and inspections of motorway bridges. For day-to-day use, the BLK360 is extremely portable, and the Recap Pro iPad software is veryuser friendly. Compared to traditional surveying, it produces高度详细和准确的数据within each scan.

Arni认识到BLK360将迅速返回最初支出的大量成本。例如，以前，安排完成完整的桥梁调查所需的总道路，最多可能要花费4,000英镑（4,456欧元）140个桥梁, that soon adds up. Using the BLK360 allows ARNI to quickly capture all essential data accurately, and without the need for costly and disruptive road closures and traffic management. It also makes it safer for surveyors who can now do their job from the hard shoulder or behind the safety barrier, removing the need to stand in the middle of the road.

BLK360捕获的细节深度超过了Arni以前能够捕获的任何东西。扫描传递给设计师，使他们能够立即查看需要在哪里需要补救工作，而不必解释不同的计划，图纸和笔记。“Gone are the days of handwritten notes and zoomed in photographs that no-one can figure what part of the structure we are looking at!”said John Jordan, lifecycle project manager at Amey Roads NI.“ BLK360已经证明自己是我们团队不可或缺的一部分，我们期待继续探索BLK360的可能性，并确定它可以改变我们的工作，创造效率并降低成本的新方法。”

乔丹因其2018年与BLK360的合作而获得了“放置人的第一类”类别的AMEY咨询奖。这个特定类别认可了对整体员工安全和福祉影响最大的个人，团队或项目。“The use of the BLK360 technology helped remove surveyors from harm's way on a number of risky jobs, including the DBFO2 work on the motorway,”said Jordan.
