After nearly 30 years, Lima Metro Line 1 is finally complete. Work on Line 1 began in 1986 but was abandoned during the economic crisis of the 1990s. The project remained on hold until 2009, when construction finally resumed. Phase two was awarded in 2011, allowing for the July 2014 completion of Lima's first metro line to connect the city's peripheral districts.
一位法官指出，第1行是“在一个非常密集的城市地区具有很大敏感性的高度复杂的项目”。该项目穿过人口稠密的部门，高速公路，利马历史悠久的地区和里马克河。
该项目在36个月内完成，比合同期限提前三个月，总计8.852亿美元。几种策略，设计和技术可以缩短完成时间，包括在构造过程中，电气，电气，天然气和其他公用事业以及12.4公里的开销高架桥的搬迁。
Precast construction helped speed construction to a completion three months ahead of schedule. The contractor used precast structural elements that could be produced simultaneously during construction. A 45,000-sq-meter precast plant produced more than 2,000 prestressed-concrete beams, 28,000 concrete slabs, 13,000 edges and 141 pier-cap beams for Line 1.
工作必须在里马克河上方和埃维塔梅托高速公路上方进行，这是该市最繁忙的通道之一，每天约37,000辆汽车。为了给公众带来最小的不便，实现这一目标，该团队使用自由局限器方法建造了节段桥，而不是在河上建造脚手架或关闭高速公路，可以实现空中建设。形式的旅行者配备了低级平台，以防止材料下降引起的事故。
Since Peru is located in the so-called Pacific Ring of Fire, a highly seismic area, Line 1's design follows the AASHTO Guide Specifications for LRFD Seismic Bridge Design 2009 standard, making it the first rail line in Peru to be developed under this standard.
Work also included 10 new passenger stations, a maintenance depot yard and the installation of electromechanical systems assembly.
第1行的乘客站作为一个高架高架桥项目，在地面上方，因此必须与利马市协调考虑城市环境。
Line 1 also integrated with some historic monuments, including the Lima City Wall and Presbitero Maestro Cemetery. To help enhance these areas, the project included a 700-m pedestrian walkway, with small squares and gardens; restoration of the portico of a historic building; construction of a site museum; and use of translucent materials for the roofs over both stations and the viaduct parapets between stations.
团队以1500万年时间没有致命的accidents, 35 minor incidents and 14 lost-time incidents, which is a record in Peru, according to the teams. Further, this achievement was made with more than 4,000 workers in various civil and electromechanical roles working both day and night.
The project team consisted of companies and professionals from Peru, Brazil, Ecuador, Venezuela, Chile, Spain, Finland, Germany, Colombia, Argentina, Canada and the United States. To facilitate ongoing communications and coordination, the team used videoconferences, calls and email as well as a remote database that could be accessed from anywhere around the globe.
在第1行的最后一步中，根据承包商的社会和环境义务，工人恢复了在项目建设期间受影响的地区，种植了5,900棵树，恢复了217,700平方米的草丛，并更换了83,800平方米的侧面和公路。目前，34.6公里的第1行每天为450,000人提供服务。
