推进墨西哥的运输基础设施

想象一个机场，每年有六个跑道，每年最多可服务1.2亿乘客，距世界上最大的大都市地区之一约25公里。该机场，墨西哥城新国际机场（NAICM），目前是墨西哥最大的基础设施项目，预计将于2020年开放。

数以百万计的旅客将飞到一个d out of NAICM, thousands of airport personnel will commute on a day-to-day basis, and hundreds of businesses will reside within or rely on the airport business district. All these airport users depend on transport infrastructure that provides an effective solution.

Mexico's Federal Secretariat of Communications and Transport (SCT) has developed a plan in which several international and Mexican companies are responsible for the design and construction of the NAICM. Besides the NAICM, a 57.7 km high-speed, modern, efficient and safe railroad is planned for connecting the city of Toluca and Mexico City.

拥有40年经验的墨西哥土木工程服务公司IUYET联盟IUYET积极参与新的国际机场和铁路的建设。

Responding to global standards

城市间列车将为整个墨西哥城地区提供巨大的运输和经济利益，并与NAICM一起为墨西哥经济提供重要的贡献。这个新机场不仅可以促进旅游业，而且还将贸易贸易，它将与墨西哥城广泛联系到世界其他地区。

For this project, Consorcio IUYET uses a variety of Leica Geosystems solutions to capture, model and analyse the data, such as total stations, theSitrack：一rail maintenance and refurbishment solution, GNSS receivers, digital levels and construction lasers combined with Leica Geosystems measurement software.

As part of the works performed by Consorcio IUYET for this project, 2,800 scans to cover 50 square km were captured and unified in a record time of two months, using the Leica ScanStation P40. The point clouds from these scans were cleaned and registered using theLeica Cyclone9.1 software for the most accurate generation of the Digital Terrain Model (DTM) of the zone. These data were used to develop the land and air design of the NAICM.

Consorcio Iuyet首席执行官Guillermo Ortiz说：“ Leica ScanStation P40使我们能够获取研究区域的3D点云，以生成数字地形模型并创建平面图。”“这使我们能够获得可靠的信息和高精度数据，以开发建筑信息建模（BIM）。”

这railroad line will have four stations and two main terminals, including a station in Metepec, close to Toluca International Airport. The train will have a maximum speed of 160 km/h. The project will also involve the construction of a 3.9 km, 30 m deep tunnel to secure environmentally protected zones; this is the most challenging task. Consorcio IUYET is the first company in North America to acquire the Leica SiTrack:One, the mobile mapping platform made especially for railroad documentation, which will be used for the construction of the high speed passenger train Toluca-Mexico City.

Ortiz说：“ Sitrack：One及其集成的P40扫描仪将用于获得铁路环境的高度准确的3D点云，以用于诸如铁路几何计算，平台测量和铁路清关。”“铁路与其他运输方式竞争的能力，尤其是与道路，对于竞争力至关重要。诸如Leica Sitrack之类的新技术：可以提供很多帮助，以帮助现代化铁路并开发更智能，更安全的铁路系统，从而使旅行者和通勤者受益。”

使用最合适的技术

这airport journey experience has a high impact on travellers’ view of the quality of the airport. The route between the destination and airport will be the passengers first and last experience of Mexico.

这railroad project began construction in July 2014 and the new line is expected to open by 2018. It would be operated with a fleet of 15 trainsets giving an end-to-end journey time of 39 minutes. Using technology that allowed for easy access, the project is on track for a timely completion.

Consorcio Iuyet在该项目的不同阶段结合了几种技术。这UAV Systems被用于摄影测量和施工检查Leica Viva GS15GNSS天线帮助建立了测量参考网络，而Leica DNA03数字水平确保了高度测定控制。

这flexibility and simplicity in the collection of the measurements allowed Consorcio IUYET to focus efforts on evaluating and analysing data rather than working out how to collect the required information.

“Thanks to the Leica Geosystems products, our project goals are clear, realistic, feasible and designed to complete the project on schedule wth high quality standards,” said Ortiz.

这firm also used theLeica Nova MS50to integrate 3D point cloud measurements that enabled the collection and visualisation of topographic survey data together with detailed high-precision scans. Ensuring fast and efficient transfer of information from field to finish is vital for this demanding project.

“The precision and compatibility between the Leica Geosystems equipment allows the best use of the resources for our company,” said Ortiz. “The need for accurate measurement is critical for our project; it supports precision and saves money and time. The reliability that our customers recognise in our work is a reflection of the quality of the Leica Geosystems solutions.”

Measurement supports innovation

墨西哥城有机会加强机场地区的发展，以确保机场对当地和国民经济的支持。

For a number of reasons, the terrestrial transport is considered to play a significant role in sustainable airport access. An effective and efficient transport network is one of the most important elements to ensure that the airport is cohesively integrated in Mexico City.

“The Mexico City New International Airport and Interurban Toluca-Mexico City train line will be a presentation for Mexican innovation,” said Ortiz. “Known as the 'Airport of the future,' it will be one of the world’s largest airports and will revolutionise airport design.”
