Digitising the construction site from the air

Author:Anne Pitkaenen

The construction industry hasn’t traditionally been considered as the most agile one in adopting new technologies and jumping into digitalisation. However, when it is of importance to the industry – getting a clear understanding of the project’s progression, a matter of cost savings or safety – changes do happen fast. This can be seen for instance in the wide adoption of machine control systems due to the automatisation, traceability and accuracy they bring into any project.

Large construction sites are like huge living organisms - they need a constant flow of current information to run smoothly. Unmanned Aerial Vehicles (UAVs)fit well to feed current data to create a clear view on site progression, adding safety and increasing cost savings.

许多分析师声称建筑是商业无人机增长最大的领域之一在六边形的地理bob体育报道系统部门，我们看到了它的发生。几年前，一些公司表示，为建筑项目创建的正射原模型和3D模型可能一次开放，然后没有使用。如今，访问新鲜数据开始成为建筑专业人员的期望。无人机被称为'democratisation tool'对于地理空间数据，因为它们提供了快速获取信息, are becomingeasier to operate，操作成本是其他数据收集方法的一小部分。

TheLeica Aibot CX无人机solution for construction is Hexagon's Geosystems’ answer to the current and future UAV needs of any construction site. This UAV solution opens opportunities for daily progress documentation, stockpile monitoring, resource tracking, and 2D and 3D site survey to get cost savings and visibility over suppliers.AIBOT CX将建筑工地带入数字时代和将数据变成智能信息to improve decision-making processes.

UAVs can assist construction companies in various ways, from营销图片到3D调查数据从进度报告到网站安全分析. The following three use cases present common ways howUAVs maximise efficiency, add transparency并为任何建筑项目提供即时节省。

调查建筑工地

Through the entire construction project, accurate and up-to-date 3D data and orthophotos of the area are crucial for planning and design. For planning and designing, users need proper as-is information. The more complete the data set, the more efficient the plan will be. UAVs can provide recent and frequently updated data whenever it is needed.

Depending on the construction site, there are several data collection methods already in place, such as:

• Machine control
• GPS
• bob apple
• 激光扫描
• Rotating lasers.

无人机不会也不应替换这些解决方案，而应该可以完成视图并在正确的位置提出其他点。这对UAV workflow to fit into the existing workflows和解决方案。无人机是访问难以访问区域的绝佳解决方案，通过覆盖周围环境并将空中数据与从其他系统收集的数据结合起来，扩大了视野。

Stockpile management

Estimating stockpiles has always been a challenging task. Estimating by guess or by climbing isn’t efficient or always safe. Knowing how much stock you have left, trusting that you have been invoiced correctly by your suppliers, and calculating the right time to reorder are important aspects for saving costs and project transparency.

用无人机执行时，计算库存量成为一项容易的任务compared to traditional surveying methods. With a UAV, it is fast, safe and easy to capture data from large or small areas from the air. This data is used to create a 3D model and make accurate volume calculations.

有了现代无人机解决方案，它是简单地使库存管理具有自动任务的准确过程；using the same flight plan and workflow repeatedly saves time and effortwhile ensuring the only change in the data collection is the amount of stock in the pile.

透明度的进度报告

Having fresh data on every stage of the project as a base for coordinating workforces, machines, suppliers and subcontractors gives an undisputable advantage. Before UAVs, this has been a costly and even dangerous process. In construction sites with strict schedules, one must be able to cost-efficiently compare the as-designed to the actual situation of the site progression.

Flying and capturing data regularly根据预定义的飞行计划，在整个项目生命周期中提供了对现场进步的透明视图，并允许在跟踪资源时记录和比较所构建的状态与规划的状态。This can be done safely from the air without disturbing the construction.

Having a constant flow of data from all phases of the project adds more transparency to the whole construction progress. Progress reporting can serve several different types of needs, such as communication with all stakeholders and planning for next steps. Users can use this data even for marketing.

Better together

Big hype in the market has been putting a lot of focus into UAVs being a “silver bullet” and a solution to all data needs. This has raised several questions whether it can really replace other technologies.Combined with existing traditional data collection methods, UAV technology can form a perfect union for smart construction data capture.

法规的变化，超越视觉线（BVLOS）和人工智能的飞行将为已经知道该过程的用户带来新的机会。我们正处于能够使用将不同技术组合在一起的可能性的起点。
