使用GNSS无纸化计划导航网站

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, developed网站计划- 世界上第一个针对土木工程的合作导航和测量应用程序。Siteplan创始人认为有必要通过土木工程的数字协作平台提高建筑工地的生产率，并创建了一个应用程序，该应用程序允许建筑团队使用自己的移动设备来浏览施工计划。

“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.

GG04 Plus是使用RTK和精确点定位（PPP）的坚固，灵活且易于使用的GNSS智能天线移动数据连接。在iOS，Android和Windows平台上运行的Leica Zeno Connect应用程序允许配置更正源，并将高智能位置提供给第三方软件应用程序。

“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.

“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，”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 stands for quality. Quality is a must when it comes to responsible activities such as staking out points,”said Beiganz.“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

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.

“在建造所有人孔和房屋连接时，我们注意到生产率的提高大幅提高，因为无需在挖掘工作之前确保滞留点或张紧施工链路进行测量。多亏了基于GPS的照片文档，现场拍摄的所有照片都会自动位于蓝图上。

“我确切地知道在某个时间的某个地方以及在那里建造的是什么。尤其是在提供建筑会计证据时，这有很大的帮助。此外，培训人们的时间很少。使用GG04 Plus和站点计划非常易于使用，”said Simon Wohlmutheder, site manager of PORR AG.”

“网站计划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.

“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 with more than twenty-five years of experience.

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.
