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.

预计数以百万计的旅行者将飞入NAICM，每天将有成千上万的机场人员上下班，并且数百家企业将居住或依靠机场商务区。所有这些机场用户都取决于提供有效解决方案的运输基础设施。

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.

应对全球标准

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.

For this project, Consorcio IUYET uses a variety of Leica Geosystems solutions to capture, model and analyse the data, such as total stations, theSiTrack:One铁路维护和翻新解决方案，GNSS接收器，数字水平和施工激光器以及Leica GeoSystems测量软件。

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Leica 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.

“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。

“The SiTrack:One and its integrated 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.

The 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.

该公司还使用了Leica 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

Mexico City has an opportunity to enhance the development of the airport region, to ensure the airport’s support to the local and national economy is increased.

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.

Ortiz说：“墨西哥城新国际机场和城市间Toluca-Mexico City Train系列将是墨西哥创新的演讲。”“被称为'未来机场'，它将是世界上最大的机场之一，将彻底改变机场设计。”
