Navigating sites with GNSS paperless plans

根据罗兰·伯杰（Roland Berger）的一项研究，建筑工地上有70％的时间用于协调和准备工作，而仅花费30％用于施工。建筑工地的准备工作中涉及的大多数任务都是经常出现的，并且易于自动化或简化。意识到这一点，并希望提高建筑工地Martin Beiganz，Marco Eigletsberger和Christian Obermayr开发的生产率SitePlan– the world's first collaborative navigation and surveying app for civil engineering. SitePlan founders saw the need to increase productivity on construction sites through digital collaborative platforms for civil engineering and created an app that allows construction teams to navigate construction plans with their own mobile devices.

“Our goal is to drive the lagging digitalisation of the civil engineering industry. However, digitalisation is a process that cannot be forced, but must grow of their own accord. That’s why we have to create certain incentives for people onsite, or more specifically, we have to create simple digital tools that relieve them of tedious tasks, such as manual measuring, tensioning a construction twine or orientate yourself in huge paper plans,”said Martin Beiganz, civil engineer and co-founder of SitePlan.

The SitePlan app allows users to quickly and easily convert traditional PDF blueprints, such as channel plans and road plans into GPS maps. By simply connecting a smartphone or tablet to theLeica GG04 plussmart antenna, construction teams can navigate and position on the blueprint with centimetre-accuracy using their tablets and smartphones.

The GG04 plus is a rugged, flexible and easy-to-use GNSS smart antenna that uses RTK and Precise Point Positioning (PPP), making high-accuracy data collection possible in real-time even in the most demanding of locations without the need for a mobile data connection. The Leica Zeno Connect app which runs on iOS, Android and Windows platforms allows for configuration of correction sources and delivers high-accuracy position to third-party software applications.

“我们正在寻找可以与iOS和Android设备配对的GNSS天线，同时确保高精度，可靠性和易用性。天线必须可集成到Siteplan的第三方软件中，”said Marco Eigletsberger, software engineer and co-founder of SitePlan.

因此，蓝图上的物体（例如轴，管道和路边）可以简单而迅速地放置 - PDF蓝图成为施工现场的数字1：1模板。基于GPS云的站点平台还提供了通过实时信息共享（例如基于GPS的照片文档）在构建团队中平稳协作的功能。因此，所有现场拍摄的照片均自动位于蓝图上。

“在开发应用程序的用户界面时，简单和直观的可用性是重中之重，”Siteplan的前端工程师兼联合创始人Christian Obermayr说。

为了确保与Leica GG04 Plus的完全兼容性，Leica Geosystems（Hexagon）与SitePlan进行了软件合作。亚搏苹果app土木工程的协作导航和测量应用程序也依靠HxGN SmartNet, a GNSS correction service built on the world’s largest reference station, to quickly determine precise positions even down to the centimetre.

“Leica Geosystemsstands for quality. Quality is a must when it comes to responsible activities such as staking out points,”贝根兹说。“我们对Leica GG04 Plus感到非常满意，因为它准确地提供了我们正在寻找的东西 - 高精度，可靠性，易用性和高质量。”

Navigating and staking out

欧洲领先的建筑公司之一Porr AG的现场经理和熟练的工人一直在奥地利的各种污水处理建设项目中使用Siteplan和GG04 Plus。工头们在没有任何纸质计划的情况下进行了固定的运河路线，可以在现场建造一个500米的下水道收集器，并在下水道建造新开发的住房庄园的构造中固定的人孔，水管和房屋连接。

“工头和熟练的工人可以轻松快速地固定各种频道管道，水管和房屋入口管，并且没有测量专家或手动测量的帮助。我们所需要的只是常规的PDF蓝图，我们自己的移动设备，SitePlan应用程序和Leica GG04 Plus。

“In the construction of all manholes and house connections, we noticed a considerable increase in productivity because there was no need to insure the staked-out points before the excavation work or to tension a construction twine for measuring. Thanks to the GPS-based photo documentation, all photos taken onsite are automatically located on the blueprints.

"I know exactly what was going on in a certain place at a certain time and what was built there. Especially when it comes to providing evidence for construction accounting, this is of great help. Furthermore, it takes very little time to train people in the use of GG04 plus and SitePlan as it is very easy to use,”Porr AG的网站经理Simon Wohlmutheder说。透明

“SitePlan is the ‘Google Maps’ for the construction site. A look at the smartphone that shows my position on the plan, is done much faster than a look at any paper plan on which I first have to orientate myself. With SitePlan – even with the internal GPS signal of the smartphone - I always know where something has to be built in a very short time and where the underground utilities run, so as not to damage them during excavation work.

“得益于站点计划和Leica GG04 Plus的组合，最终不再需要费力的手动测量工作。工作流程非常快速，流畅。只需通过蓝牙将智能手机连接到Leica GG04 Plus - 打开SitePlan应用程序中的蓝图，然后在GeoreChorefend Plan上显示带有十字准线的蓝图，您的厘米准确的位置显示出您想悬而未决的点 - 完成 - 完成！”Reinhold Schnelzer说，PORR-foreman with more than twenty-five years of experience.

Building on the existing product, the SitePlan team is already developing other innovative features, such as GPS-based task management and GPS-based onsite measurement for accounting. Since SitePlan and the GG04 plus can not only be used in sewer construction work, but in all areas of civil work, various European construction companies will now implement further projects in the areas of roads, railways, dams, water and earthworks with the GG04 plus and SitePlan solution.

“建筑行业的数字化s in its early stages and there is still a lot to do. We are really looking forward to the challenges ahead and it gives us great pleasure to help shape the digitalisation of the civil engineering industry with simple digital tools made for people onsite,”concluded Beiganz.
