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.

与雷加拉格尔有一个长期合作关系ca Geosystems Ltd, having successfully used Leica Robotic solutions since the TPS1100 model range. In June 2015 when Leica Geosystems launched the new Captivate range, Gallagher was keen to invest in all the advantages of this new technology. To date, Gallagher is now equipped with 17 Captivate one person kits and a GNSS unit, showing their loyalty and trust to the Leica Geosystems brand. They were keen to put them into use.

加拉格尔客户接洽J和JFranks 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 Geosystems亚搏彩票手机版下载的产品和解决方案，以便按预算和准时完成该项目。

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，以免造成任何不必要的破坏。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，因为它是为诸如采石场站点入口的苛刻环境而设计的，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，可以轻松在采石场周围运输。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.

Using this survey data from Captivate, a 3D model was produced of the site and the design was determined for the new work. The survey data helped Gallager to decide on the best alignment of the road, making sure that the existing contours of the field were followed. Then with the new design and services, data was loaded onto the Leica CS35 tablet and available on site in the 3D environment within Captivate. All elements of the site could be staked out with a ‘live’ understanding of any potential clashes or pinch points with the utilities.

Completing a complex construction project like this one at Mercers South Quarry wasn’t without its challenges. Making sure the existing statutory services were deep enough not to be damaged was imperative to the project. The Captivate kit from Leica Geosystems made sure the setting out and allocation of these services was quick and easy. Without the surveying equipment from Leica Geosystems and if the services were damaged in any way, it could have set the project back six months or more. Other obstacles included a footpath which was in the way and needed to be removed. Trees and shrubbery also needed to be cut down surrounding the quarry with minimum disruption to local pedestrians and residents. The contract was completed within tight time constraints to minimise the disruption to local pedestrians and motorists.

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，这将是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”.
