According to a study by Roland Berger, 70% of the 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——世界上第一个协同导航和年代urveying 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.

“我们的目标是推动土木工程行业的滞后数字化。但是，数字化是一个不能强迫的过程，但必须自行发展。这就是为什么我们必须为现场的人们创造某些激励措施，或者更具体地说，我们必须创建简单的数字工具，以减轻他们乏味的任务，例如手动测量，张紧施工麻烦或在巨大的纸质计划中定位自己，”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.

“We were looking for a GNSS antenna that can be paired with iOS and Android devices while ensuring high accuracy, reliability and ease of use. The antenna must be integrable into SitePlan’s third-party software,”said Marco Eigletsberger, software engineer and co-founder of SitePlan.

Objects on the blueprints, such as shafts, pipes and road edges can thus be staked out simply and quickly – PDF blueprints become a digital 1:1 template for the construction site. The GPS cloud-based SitePlan platform also provides features for smooth collaboration within the construction team through real-time information sharing, such as GPS-based photo documentation. Thereby all photos taken onsite are automatically located on the blueprints.

“When developing the user interface of our app, simple and intuitive usability was a top priority,”said Christian Obermayr, frontend engineer and co-founder of SitePlan.

To guarantee full compatibility with the Leica GG04 plus, Leica Geosystems, part of Hexagon did software cooperation with SitePlan. The collaborative navigation and surveying app for civil engineering also relies onHXGN 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。”said Beiganz.“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.

“Foremen and skilled workers have staked out various channel pipes, water pipes and house entry pipes easily and quickly with high accuracy and without the help of surveying experts or manual measuring. All we needed was a conventional PDF blueprint, our own mobile devices, the SitePlan app and the 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,”said Simon Wohlmutheder, site manager of PORR AG.”

“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。

“Thanks to the combination of SitePlan and the Leica GG04 plus, the laborious manual measurement work is finally no longer necessary. The workflow is very fast and smooth. Simply connect your smartphone to the Leica GG04 plus via Bluetooth – open the blueprint in the SitePlan app and then your centimetre-accurate position is shown on the georeferenced plan with a crosshair – move to the point you want to stake out – Done!” said Reinhold Schnelzer,Porr Foreman拥有超过25年的经验。

Siteplan团队在现有产品的基础上已经开发了其他创新功能，例如基于GPS的任务管理和基于GPS的现场测量值。由于Siteplan和GG04 Plus不仅可以在下水道建设工作中使用，而且在民用工作的所有领域，因此各种欧洲建筑公司现在将在道路，铁路，水坝，水和土方工程领域实施进一步的项目。和站点平面解决方案。

“建筑行业的数字化处于早期阶段，还有很多事情要做。我们真的很期待未来的挑战，这使我们非常高兴能够通过为人们提供的简单数字工具来帮助塑造土木工程行业的数字化，”concluded Beiganz.
