Quarrying a new site entrance

Gallagher Ltd is Kent’s premier building, civil engineering, quarrying and property business, with a reputation for doing things professionally and getting the job done. The Gallagher Group started in 1973 and is based in Kent, England. The business started out as a grounds work contractor and has since established into a main contractor and principle contractor, offering the best in civil engineering, property development, design and build contracting and quarrying.

Gallagher与Leica Geosystems Ltd建立了长期的合作伙伴关系，自TPS1100型号范围以来，已经成功使用了Leica机器人解决方案。2015年6月，当Leica Geosystems推出了新的Caintivate系列时，Gallagher渴望投资于这项新技术的所有优势。迄今为止，加拉格尔（Gallagher）现在配备了17个吸引人的套件和一个GNSS单元，表现出对Leica Geosystems品牌的忠诚和信任。他们渴望将它们使用。

Gallagher was approached by their customer J and J Franks Ltd to work on the Mercers South Quarry on the Old Reigate Road in Betchworth, Surrey. They were awarded the contract for the construction of a new site entrance to the quarry and works were undertaken over a two month period. A diversion was set up to allow pedestrians and motorists to access the villages either side of the access way. The new access way was fundamental to J & J Franks, allowing it to continue operating its quarry activities and providing continued employment for its skilled workforce.

Leica Captivate software was used for the project to help reduce any unnecessary costs and delays associated with complex projects and were fundamental to the setting out of the project.

该项目的初始阶段是Gallagher构建切割和盖隧道，以形成现场入口。为此，首先有必要检查现有的法定服务（BT，UKPN –LV + HV和天然气），例如水，天然气和电话线，这增加了工作的挑战。为了检查现场的深度，必须制定试验孔，以确保站点的入口足够深，可以放入钟声（现场入口）。使用Leica Caintivate解决方案意味着更好的测量精度，即快速，轻松地提供最小的细节。使用Leica Geosystemsbob综合app下载的产品和解决方案，以便按时完成该项目。

在此项目中介绍时，位置准确性至关重要，至关重要的是要准确了解新作品可能与任何法定服务发生冲突，以免引起任何不必要的破坏。为此选择了Leica Viva TS16和Leica Viva GS14，在项目开始时，Leica Viva GS14也用于基本切割和填充操作。Leica Viva GS14非常适合这种情况，因为它是针对苛刻的环境（例如网站入口）制造的，并且在极端温度和天气条件下提供了真正的耐力。强大而轻巧，可以轻松在采石场附近运输。简单，准确且易于使用，Leica Viva GS14与新的CS35平板电脑合作，该平板电脑运行了Caintivate软件，并连接到SmartNet，以进行准确的GNSS RTK校正。

The Leica Viva TS16 ‘self learning’ one person total station was chosen because of its versatility to adapt to any environmental condition, boding well for a quarry site. Running the Leica Captivate onboard software, the most comprehensive onboard capability available, the exact conditions of the quarry site could be surveyed and recorded. This provided an understanding of any potential clashes or pinch points with the utilities. The Leica Captivate software allows for a really great user experience.

使用Captivate的此调查数据，生产了该站点的3D模型，并确定了新工作的设计。调查数据帮助加拉格（Gallager）决定了道路的最佳对齐，确保遵循该田野的现有轮廓。然后，使用新的设计和服务，将数据加载到Leica CS35平板电脑上，并在Captivate内的3D环境中在现场提供。该网站的所有元素都可以通过“实时”了解与公用事业的任何潜在冲突或捏点的“实时了解”。

在Mercers South Quarry完成这样一个复杂的建筑项目并非没有挑战。确保现有的法定服务足够深，不要损坏该项目。Leica Geosystems的Caintivate套件确保这些服务的设置和分配很容易。如果没有Leica Geosystems的测量设备，并且如果服务以任何方式损坏，它可能会使该项目返回六个月或更长时间。其他障碍包括一条行走路，这是一条路线，需要去除。树木和灌木丛也需要在采石场周围砍伐，最少对当地行人和居民造成。该合同在紧迫的时间限制内完成，以最大程度地减少对当地行人和驾驶者的破坏。

该项目始于2015年7月，道路的第一部分于2016年1月完成。一旦采石场充满了沙子和垃圾填埋场，Gallagher将返回采石场，以完成通往永久采石场区域的通道。然后，它将成为一个全新的工作采石场，并拥有新的通道和新入口地点。新功能的采石场将使整个社区受益，并为该地区提供重要的新机会。

The Leica CS35 tablets offer them so much more than a conventional total station controller, being a full Windows 8.1 Computer, the capabilities it offers for onsite use are almost limitless. Gallagher has already installed AutoCad and their regular IT services onboard. The Leica CS35 tablets can be used for everything from setting out and surveying, to filling in check sheets, documenting and photographing as-builts, exchanging important data and doing email.

"We wouldn’t have been able to complete this construction project for J and J Franks without the excellent kit and solutions from Leica Geosystems”, remarks Ken Maillinson, Technical Contracts Manager at Gallagher. “We always choose Leica Geosystems solutions for our surveying jobs as we can rely on the high quality of the instrument and the accuracy of the measurements. Furthermore the support and excellent after care received from their Technical Support and Technical Service teams are second to none”.
