Panama Subway L3<\/span><\/b><\/span><\/p>\n

<\/span><\/b><\/span><\/p>\n

Panama Metro Line 3<\/strong> is one of the most technically complex railway infrastructure projects currently under development in Central America and represents the largest expansion of the Panama Metro network. The project has been conceived to connect Panama City with Panama Oeste Province<\/strong>, crossing the Panama Canal via a new railway bridge and providing a high-capacity public transport solution for one of the country’s fastest-growing metropolitan corridors. The line extends approximately 24.5 km<\/strong>, comprises 14 stations<\/strong>, and has been designed as a straddle-type monorail system<\/strong>, selected for its high passenger capacity, operational reliability and adaptability to the challenging urban and geotechnical conditions along the alignment<\/span><\/p>\n

Virtually the entire alignment is supported on elevated reinforced concrete viaducts<\/strong>, forming a highly repetitive structural system consisting of deep foundations, large-diameter bored piles, reinforced concrete columns, precast pier caps, portal beams and bridge deck structures. The industrialization of these structural elements proved essential for maintaining the demanding production rates required across multiple simultaneous construction fronts. The project also incorporates innovative engineering solutions such as Glass Fibre Reinforced Polymer (GFRP) reinforcement<\/strong> in selected structural components, improving durability and long-term performance in aggressive environmental conditions<\/p>\n

From the perspective of fabricated reinforcing steel, Line 3 represents one of ERSIGROUP<\/span><\/b><\/span>‘s<\/strong> largest international projects. The company has undertaken the industrialized fabrication of reinforcement for bored piles, columns, pier caps, portal beams and other major structural components, implementing a prefabrication strategy that industrialized approximately 86% of the structural works<\/strong>. The high level of standardization enabled reinforcement optimization, efficient bar scheduling and advanced logistics planning, ensuring a continuous supply of reinforcement fully synchronized with the simultaneous progress of multiple construction fronts<\/p>\n

ERSIGROUP<\/span><\/b><\/span><\/strong>\u00a0is responsible for the cutting, bending, fabrication, prefabrication and installation of approximately 70,000 tonnes of reinforcing steel<\/strong>, together with the production of 21,000 tonnes of precast bored piles<\/strong> and 17,000 tonnes of precast pier caps, columns, corbels and portal beams<\/strong>. Among the project’s most significant structural elements are precast bored piles up to 2.35 m in diameter and weighing as much as 44 tonnes<\/strong>, whose fabrication, transportation and installation required dedicated engineering and logistics solutions. Through the implementation of highly industrialized production methods, ERSIGROUP<\/span><\/b><\/span>\u00a0achieved production rates of four reinforcement cages and columns, four pier caps and four portal beams per day<\/strong>, ensuring outstanding productivity, dimensional accuracy, full material traceability and rigorous quality control throughout the project<\/p>\n

The combination of detailed engineering, industrialized reinforcement fabrication, large-scale prefabrication and highly specialized logistics has consolidated ERSIGROUP<\/span><\/b><\/span>‘s<\/strong> participation in one of Latin America’s most significant railway infrastructure projects, demonstrating the company’s capability to deliver comprehensive fabricated reinforcing steel solutions for large-scale transportation infrastructure through highly industrialized construction processes<\/p>\n
