Navigating sites with GNSS paperless plans

据罗兰贝格(Roland Berger)的一项研究,70%的time on construction sites is spent on coordination and preparation and only 30% is spent on construction. Most of the tasks involved in the preparatory work of a construction site are recurrent and easy to automate or streamline. Aware of this and looking to increase productivity on construction sites Martin Beiganz, Marco Eigletsberger and Christian Obermayr, developedSitePlan– 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.

PDF blueprints are usually the interface between planning offices and construction companies. SitePlan creators found a way of making the reading of blueprints more attractive. 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自动位于蓝图上。

“When developing the user interface of our app, simple and intuitive usability was a top priority,”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，Hexagon的Leica Geosystems与SitePlan进行了软件合作。bob体育报道土木工程的协作导航和测量应用也依赖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 Geosystems代表质量。当涉及负责任的活动（例如出现积分）时，质量是必须的。”贝根兹说。“We are very satisfied with the Leica GG04 plus as it delivers exactly what we were looking for - high accuracy, reliability, ease of use and very high quality.”

导航和放下

Site manager, foremen, and skilled workers of PORR AG, one of the leading construction companies in Europe, have been using SitePlan and the GG04 plus in various sewage construction projects in Austria. Foremen have staked canal routes without any paper plans onsite to construct a 500-metre sewer collector, and staked manholes, water lines and house connections in the construction of sewers for newly-developed housing estates.

“工头和熟练的工人可以轻松快速地固定各种通道管，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是建筑工地的“ Google Maps”。查看显示我在计划上的位置的智能手机的完成速度要比我首先要定位自己的任何纸质计划要快得多。使用SitePlan（即使使用智能手机的内部GPS信号），我一直都知道必须在很短的时间内以及地下公用事业运行的地方建造某些东西，以免在挖掘工作中损坏它们。

“得益于站点平面和Leica GG04 Plus的结合，最终不再需要费力的手动测量工作。工作流程非常快，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Georefercted 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拥有超过25年的经验。

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.

“The digitalisation of the construction industry is 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.
