从空中数字化建筑工地

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.

Many analysts claim thatconstruction is one of the biggest areas of growth in commercial UAVand at Hexagon's Geosystems division we see it happening. A couple of years ago some companies said the orthophotos and 3D models created for construction projects were opened maybe once and then left unused. Access to fresh data, nowadays, starts to be an expectation by construction professionals. UAVs have been called the“democratisation tool'for geospatial data since they offerfast access to information, are becoming更容易操作, and the operating cost is a fraction of other data collection methods.

TheLeica Aibot CX UAV建筑的解决方案是Hexagon的地理系统对任何建筑工地的当bob体育报道前和未来无人机需求的回答。这种无人机解决方案为每日进度文档，库存监控，资源跟踪以及2D和3D站点调查开放了机会，以节省成本和对供应商的可见性。Aibot CX brings the construction site into the digital ageandturns data into intelligent informationto improve decision-making processes.

UAVs can assist construction companies in various ways, frommarketing pictures to 3D survey dataand from progress reporting to sitesafety analysis. The following three use cases present common ways howUAVs maximise efficiency, add transparencyand offer immediate savings for any construction project.

Surveying the construction site

通过整个施工项目，该区域的准确和最新的3D数据和正截骨对规划和设计至关重要。为了计划和设计，用户需要适当的信息。数据集越完整，计划的效率就越有效。无人机可以在需要时提供最新的和频繁更新的数据。

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

• Machine control
• GPS
• bob apple
• Laser scanning
• Rotating lasers.

UAVs will not and should not replace these solutions but can complete the view and put additional points in the right place. It is important for theUAV workflow to fit into the existing workflowsand solutions. UAVs are an excellent solution for accessing hard-to-access areas, widening the view by covering the surroundings and combining aerial data with data collected from other systems.

库存管理

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.

Calculating volumes of stockpiles becomes an easy task when executed with a UAVcompared 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.

With a modern UAV solution, it issimple to make stockpile managementan accurate process with automated missions;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.

Progress reporting for transparency

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, according to a pre-defined flight plan, provides a transparent view of the site progression throughout the project lifecycle and allows to document and compare the as-built status with the as-planned while tracking resources.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.

在一起更好

市场上的大型炒作一直将重点放在无人机是“银弹”和解决所有数据需求的方法上。这就提出了几个问题，它是否真的可以取代其他技术。与现有的传统数据收集方法相结合，无人机技术可以成为智能施工数据捕获的理想结合。

监管的变化,除了视觉李飞行ne of sight (BVLOS), and artificial intelligence will bring new opportunities to users who already know the process. We are just at the starting point of being able to use the possibilities of combining different technologies together.
