The city of São Paulo is literally under construction. Through the Municipal Department of Urban Infrastructure (Siurb), the City of São Paulo carries out the largest program for the recovery and maintenance of bridges and viaducts in the history of the city. In 2023 alone, the interventions have an approved contribution of 650 million reais and the expectation is to complete 300 works by the end of 2024. This volume is unprecedented in the city and is part of the Special Works of Art Maintenance Management Program ( OAE), created in 2018.
IEME Brasil
IEME Brasil has participated in the program since 2020, providing inspection, testing and structural analysis services. The contract covers the Domingos de Moraes, João Beiçola, Olavo Fontoura, 31 de Março, Carlos de Campos and Orlando Murgel viaducts, as well as the Anhembi, Estaiada Governador Orestes Quercia, Arujá, Senador José Ermírio de Moraes and Aurélio Batista Road Complex bridges.
A significant portion of these OAEs, identified as priorities, are currently undergoing rehabilitation and IEME remains involved with some of them, which demonstrated the need for reinforcements and more in-depth studies, with a view to adapting structures to increased traffic or due to problems of maintenance. Complementary reinforcement projects are currently under development and will be made available to the City Hall in the coming weeks.
Recently, IEME Brasil signed a new contract with Siurb, in a consortium with Alphageos, to carry out a series of special inspections, tests and structural verifications. Among the structures to be examined are the Milton Leão, Júlio de Mesquita Filho 2, Itinguçu, Pedroso (Bispo Tid Hernandes), Mie Ken, Shuei Uetsuka and Jaceguai viaducts.

About the Program
São Paulo has hundreds of bridges, viaducts and footbridges, most of them under the responsibility of the City Hall, which is responsible for maintaining and conserving them. With the aim of establishing a permanent culture of routine inspections and preventive maintenance, promoting integrity and extending the useful life of structures, Siurb published Ordinance No. 40/2018, creating the Special Works of Art Maintenance Management Group.
Linked directly to the Secretary’s Office, the Group is responsible for establishing a program of routine and periodic inspections to subsidize the planning, design and actions of repairs, renovations and reinforcements of the OAE, and must verify, among other pertinent aspects, the situation pavement, sidewalk, vegetation, infiltrations, overhaul of structures (infra, meso and superstructure), undermining, support equipment, expansion joints, guardrails, drainage and cleaning.
Thus began the Maintenance Management Program for Special Engineering Works in the City of São Paulo, which follows the guidelines of the ABNT NBR 9452 standard, with annual visual inspections, special inspections every five or eight years and emergency inspections. if there is an emergency demand. The program allows available resources to be used more efficiently, hierarchizing and prioritizing maintenance needs.
