监视科隆历史中心的遗产酒店

Author: Steven Thurgood

在古城科隆,Dom酒店是one of the oldest Grand Hotels in Europe. It first opened in 1857, underwent its first renovation in the 1800s, another after the Second World War and has been in a process of modernisation since 2014. Germany’s Cultural Heritage Policy ensures the preservation of historic buildings and culturally significant structures, meaning that the 5-star hotel’s original façade and staircase must remain. Construction operations began in 2016 and partial demolition of the internal structure was agreed upon in 2019.

测量工程专家，Vermessungsbüro KDSwas appointed by the project to undertake the structural monitoring of the heritage building during construction. Following the design risk assessments for the demolition, structural moment tolerances were calculated for the deformation and movements of the heritage faç阿德。马丁的vermessungsbüro KDS worked with Leica Geosystems’regional monitoring solutions expert, Heiner Gilleßen，设计一个监视敏感结构的计划。

部署用于灵敏度的解决方案

Leica Geosystemswould usually recommend deploying theLeica Nova TM60andGeoMoS Edge在酒店结构上测量棱镜的解决方案，但是立面上的支撑架及其覆盖物意味着光学系统没有视线。取而代之的是，吉利斯建议使用更广泛的六角形地理系统，莉卡地理系统和第三方投资组合中的解决方案。亚搏苹果app地缘监测解决方案。This suite allows flexibility and speed in understanding and reacting to complex demands in monitoring projects.

With the specification requiring monitoring of the façade, yet no physical access or line of sight for optical devices, Heiner Gilleßen recommended wireless tilt sensors that could be installed quickly and easily while requiring little maintenance. All the data from the sensors could still be managed and visualised fromLeica GeoMoS Now!——一个基于web的应用程序,它提供了简单,但是secure access for authorised personnel to view data. This combination of tools gave the customer the capability to add systems without having to learn or implement a new software suite.

In total, 18 sensors were installed onto various locations on the façade, allowing precise automated monitoring to be completed for the rotation of the façade as demolition of the inner hotel structure was completed. This included 15 two-axis inclination sensors, a gateway and a solar panel. Distance sensors were also used in combination with the basic tilt sensors to measure offsets from the structural walls and ensure the geometry of the structure remained constant. This was particularly relevant as the elevator shaft in the hotel was to remain undisturbed by the construction teams working on the project. Constant offset and inclination readings enabled the safe monitoring of the elevator shaft.

使用自动化生成数据驱动的结果

自2019年9月安装以来，Leica解决方案进行了18 readings every 30 minutes, producing approximately 550,000 data records with an extra 1,000 readings per day. This was available in GeoMoS within 120 seconds of data measurement on-site and made available on the cloud platform of GeoMoS Now!, providing live data around the clock.

When the works programme was extended due to archaeological finds in the basement excavation, the extension of the monitoring scheme’s life was not a problem. The equipment installed is designed to last maintenance-free for years due to 30-minute data acquisition intervals, self-powered internal batteries and IP65 rated enclosures for all-weather working. Gilleßen provided local and remote training for those new to the scheme.

Protecting the heritage of the Dom Hotel

Martin Reck和VermessungsbüroKds更广泛的团队对提供的解决方案非常满意。实际上，他们还利用了整个项目的手动测量工作的测量解决方案，包括Leica Sprinter 150数字水平，Leica DNA03，Leica LS15，Leica Disto，Leica Viva GS12 GNSS,Leica Viva GS16 GNSS，，，，Leica TS15 and TS16 Total StationandLeica Viva CS10 Field Controller。

自动化对于确保立面能够留在Dom Hotel至关重要。Leica Geosystems带着120间客房和套房，可供科隆游客享用，在保护酒店丰富的遗产方面发挥了重要作用。随着城市的发展和结构的发展，诸如地缘监测解决方案andLeica GeoMoS Now!正在确保结构安全和历史保存。
