Patio Workshop Branch Tunnel | Lima, Peru
Lima Metro-Line 2
The Patio Workshop Branch Tunnel for the new Lima Metro – Line 2 is part of one of the most important Lima Metro Tunnel Project segments built in Lima, Peru. This stretch is the second Metro route under construction. When complete, the tunnel will run east to west 82' (25?m) below the city for 16.8 miles (27?km) and contain 27 stations. Development of the project began in early 2016, with an estimated completion date of December 2025. This project will benefit 2.5 million residents from 13 districts of Lima and neighboring Callao. It will have a capacity of 600,000 passengers a day. It will also reduce the length of the journey between Ate Vitarte and Callao from 2 hours and 30 minutes to just 45 minutes.
Partnerships
The construction of the project was awarded to Consorcio Linea 2 Metro Lima, composed of a group of various highly prestigious construction companies in Spain, Italy, and Peru. These companies are FCC – Global Operator of Infrastructures and Services, Dragados S.A., Iridium Concesiones de Infraestructuras, Ansaldo STS, Ansaldo Breda, Salino Impregilo, and Cosapi S.A. With more than 50 years of experience, Cosapi S.A. is considered one of the most prestigious Peruvian companies in the industry. Over the years, EFCO and Cosapi have developed various projects in the country, namely, Centro Commercial Real Plaza Pucallpa, Planta de Tratamiento San Jeronimo in the Province of Cusco, remodeling of the National Stadium of Lima, Highway Interchange Sanchez Cerro in Piura, gables of Quellaveco Tunnel in Moquegua, etc.
"Several problems were faced during the construction process, but with the help of EFCO's Field Service and EFCO's Engineering Department, they were successfully solved and kept us moving forward productively."- Edwar Cuba, Production Engineer
First Stage of Project
The project consists of an open pit tunnel with both straight and curved areas and will be built in two stages. The first stage is the construction of the gable walls, which have a total length of 1,640' (500?m). For the 13' (4?m) tall gable walls, EFCO provided PLATE GIRDERS? to do the straight sections and REDI-RADIUS? to do the curved areas. The formwork assembly included all-steel face sheets, support brackets, anchors, and a wheel system to move the 21'-8" (6.60?m) formwork module. The straight part consisted of 20'?(6?m) long castings, while the bend of the portal was 17'-9" (5.40?m) long.
Second Stage of Project
The second stage uses 3,660?yd3 (2,800?m3) of concrete to create the 492' (150?m) long crown. A traveler supports and moves the REDI-RADIUS forms, which consist of 20 SUPER STUD? frames secured together with PLATE GIRDERS. The PLATE GIRDERS create a beam that allows the 16.5-ton (15-tonne) traveler to be supported and moved on rollers.
