To promote industrialization and improve the project's constructability, we implemented the Virtual Design & Construction (VDC) methodology, combined with a system of prefabricated reinforcement cages (PRC) elements in constructing an 870- meter span bridge located in Lima, Peru. The objective was to reduce structural rebars' assembly times, replace the traditional on-site processes of cutting, bending, and assembling steel with an industrial process based on systems of PRC steel elements. As a result, the assembly times of the structural item were reduced by 31%, thanks to the use of PRC elements. In addition, due to the VDC methodology, a 100% buildable design of the PRC elements was achieved. KEYWORDS VDC, BIM, bridges, industrialized construction, prefabricated reinforcement. INTRODUCTION Traditional construction systems can imply unnecessary expenses and loss of resources, either in labor or in materials and tools, which can affect the quality of the final project (Penadés Martí, 2002). Therefore, humans have always sought to improve and optimize every process they perform, eliminating waste. Construction is one such process, which has been subjected to several changes and revolutions (López Flores, 2018). In recent decades, there has been a growing interest in advances in industrial construction. As Qi et al. (2021) explain, industrialized construction integrates design and optimization tools to solve complex challenges in construction projects. The most discussed benefits of industrialized construction are cost reductions, productivity improvement, and the reduction and optimization of construction times. 1 Student, Civil Engineering Department, Universidad de Lima, Lima, Peru, 20171572@aloe.ulima.edu.pe, https://orcid.org/0000-0002-8604-907X 2 Student, Civil Engineering Department, Universidad de Lima, Lima, Peru, 20162640@aloe.ulima.edu.pe, https://orcid.org/0000-0002-2286-8754 3 Full Professor, Civil Engineering Department, Universidad de Lima, Lima, Peru, delsavio@gmail.com, https://orcid.org/0000-0002-6067-6606 4 Project Coordinator, TSC Innovation, Lima, Peru, apalpan@tscinnovation.com 5 Project Coordinator, TSC Innovation, Lima, Peru, evalle@tscinnovation.com 6 General Manager, TSC Innovation, Lima, Peru, fquiroz@tscinnovation.com
