Advancing Mexico's transportation infrastructure

Imagine an airport featuring six runways and serving up to 120 million passengers per year, located approximately 25 kilometres from one of the largest metropolitan areas in the world. That airport, the Mexico City New International Airport (NAICM), is currently the largest Mexican infrastructure project and expected to open in 2020.

Millions of travellers are expected to fly into and 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.

墨西哥的联邦通信与运输秘书处（SCT）制定了一项计划，其中几家国际和墨西哥公司负责NAICM的设计和建设。除了NAICM外，还计划连接托卢卡市和墨西哥城的57.7公里高速，现代，高效和安全的铁路。

Consortium IUYET, a leading Mexican civil engineering services company with 40 years of experience, is actively involved in the construction of the new international airport and railroad.

响应全球标准

The Interurban train will provide significant transport and economic benefits for the whole Mexico City region, and, along with NAICM, will be an important contributor to Mexico’s economy. This new airport will not only facilitate tourism but also trade, and it will connect widely Mexico City to the rest of the world.

对于这个项目，Consorcio IUyet使用各种Leica GeoSystems解决方案来捕获，建模和分析数据，例如总站，亚博5分钟快三SiTrack:Onerail maintenance and refurbishment solution, GNSS receivers, digital levels and construction lasers combined with Leica Geosystems measurement software.

作为Consorcio Iuyet为该项目所做的作品的一部分，使用Leica ScanStation P40捕获了2800次扫描以覆盖50平方公里的范围，并在两个月的创纪录时间内统一。这些扫描中的点云已清洗和注册狮子旋风9.1该区域最精确生成数字地形模型（DTM）的软件。这些数据用于开发NAICM的土地和空气设计。

“The Leica ScanStation P40 enabled us to acquire 3D point clouds of the study area to generate a Digital Terrain Model and create planimetric maps,” said Guillermo Ortiz, CEO at Consorcio IUYET. “This allows us to gain reliable information and high precision data for the development of the Building Information Modelling (BIM).”

铁路线将有四个车站和两个主要航站楼，其中包括梅特佩克（Metepec）的一个车站，靠近托卢卡国际机场。火车的最大速度为160 km/h。该项目还将涉及建造3.9公里，30 m的深隧道，以保护受环境保护的区域；这是最具挑战性的任务。Consorcio Iuyet是北美第一家收购Leica Sitrack的公司：One是专门用于铁路文档的移动地图平台，该平台将用于建造高速旅客火车Toluca-Mexico City。

“SiTrack:一个及其集成P40 ScanStation will be used to obtain a highly accurate 3D point cloud of the railroad environment for applications such as rail geometry calculations, platform gauging and rail clearancing,” said Ortiz. “Rail’s ability to compete with other modes of transport, in particular with road, is crucial for its competitiveness. New technology such as the Leica SiTrack:One can offer much to help modernise railways and develop a smarter and safer rail system that will benefit travellers and commuters.”

Using the most suitable technology

The 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.

The 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 combined several technologies in different stages of this project. TheUAV Systemswere used for the photogrammetry and construction inspection while theLeica Viva GS15GNSS antenna helped create the Geodesic Reference Network, and the Leica DNA03 digital level ensured altimetry control.

收集测量值的灵活性和简单性使Consorcio IUyet能够将精力集中在评估和分析数据上，而不是计算如何收集所需信息。

“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.

The 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。

由于多种原因，陆地运输被认为在可持续机场通道中起着重要作用。有效，有效的运输网络是确保机场在墨西哥城内凝结的最重要要素之一。

“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.”
