"TECHNOLOGICAL METHOD FOR QUALITY CONTROL AND MANAGEMENT IN INFRASTRUCTURE WORKS" TECHNICAL FIELD

[001] This invention patent refers to a technological method for quality control and management in infrastructure works, applied to civil engineering and the management of large-scale linear construction projects. This technological method is innovative in that it integrates a set of operational modules executed by means of a computer program equipped with artificial intelligence, structured in a sequential set of steps that include the data recording stage in the field, validation by the construction inspection, attachment of quality evidence by the construction company, validation of quality by the client, review of measurements by the construction company, final contractual approval by the client, and the generation of outputs and reports. In this way, the method ensures complete end-to-end traceability between the execution of services, quality control, and contractual management of the project. HISTORY OF THE TECHNIQUE

[002] Road infrastructure works demand rigorous technological control of the services performed, in order to ensure compliance with projects, technical specifications, regulatory standards and contractual requirements. The efficiency of data collection is crucial for the final quality of the work, for mitigating technical and financial risks, and for transparency in contract management.

[003] Quality control in infrastructure works in Brazil basically involves the systematic collection of execution data, the performance of standardized technical tests, sequential validation by different agents, and the linking of results to the measurement and invoicing of services.

[004] It turns out that quality control in infrastructure projects in Brazil is predominantly manual, decentralized, and prone to errors, resulting in low approval rates, lack of standardization, lack of traceability of tests, and reduced integration between field teams, laboratories, and managers. This scenario generates rework, increased costs, negative impacts on the schedule and Net Present Value (NPV) of the projects, and prevents data consolidation. Petition 870260011326, dated 05 / 02 / 2026, page 6 / 21 2 / 8 structured for predictive analytics and evidence-based decision making.

[005] The solutions currently available consist mostly of “generic workflows or non-specialized management tools, which do not take into account the technical particularities of soil, pavement, concrete, asphalt and drainage tests, nor do they offer native integration with quality plans, physical-financial measurements and compliance requirements of the road sector.

[006] In this context, document no. US20190139164A1 describes a construction management system focused on collecting vehicle and machinery location data and issuing notifications based on delimited areas, with a focus on logistics, safety, and operational coordination. However, this document does not describe a structured digital workflow for technological control of tests, with sequential validations, document traceability linked to the activities performed, nor the automatic generation of technical reports associated with measurements and contractual values ​​typical of road construction projects.

[007] Similarly, document no. US20200279202A1 describes a device for managing construction projects based on communication between portable devices and the dynamic assignment of tasks on the construction site. However, it does not integrate quality approvals and physical-financial measurements, with automatic blocking of unapproved measurements, as does the present application which encompasses a more in-depth control of the entire chain of operations of the work.

[008] Thus, it is a fact that the documents cited in the paragraphs above, despite belonging to the same field of application, do not present any of the characteristics of the method now improved, thus guaranteeing that it meets the legal requirements for patentability. OBJECTIVES OF THE INVENTION

[009] The objective of the invention is to provide a computer-implemented method, specialized for infrastructure works, which, through a set of steps, is capable of conducting, in an automated and auditable manner, the technological control and quality management chain, integrating field execution records, technical evidence and test results, with sequential validations by distinct profiles, in order to reduce communication failures, increase standardization and enhance traceability and Petition 870260011326, dated 05 / 02 / 2026, page 7 / 21 3 / 8 reliability of technical information.

[010] It is also an objective of the invention to enable robust operation in low-connectivity environments, through offline validation in the mobile application and subsequent synchronization with a central cloud server, maintaining the automatic association of georeferencing and attachment of evidence, as well as ensuring audit logs and update history per test, consequently supporting audits, compliance and technical accountability.

[011] It is also an objective of the invention to technically integrate quality approval into the physical-financial measurement and contract management process, by means of automatic blocking of unapproved measurements and automatic release after technical approval, reducing litigation, rework and costs, as well as enabling automatic generation of consolidated reports and structured exports to external systems, with traceability between execution, quality and billing.

[012] The objective of the invention is to provide real-time management visualization through dynamic dashboards, compliance indices and a map of critical works with urgency indicators derived from rejections and recurrence of rework, allowing evidence-based decision making and measurable improvement in operational efficiency and predictability of contractual performance.

[013] Another objective of the invention is to present a technological method of control and management that includes a mobile application module, intended for filling out and sending field tests, with support for georeferencing and attachment of evidence, such as photographs, reports and measurements. This module allows the direct, real-time recording of soil, pavement, concrete, asphalt, and other tests through dynamic and customizable forms, with automatic georeferencing, image and technical report upload, instant synchronization with a central server, and offline validation, ensuring continuity of operation in regions without internet access.

[014] Another objective of the invention is to present a technological method of control and management that includes an administrative web module, responsible for consolidating the information received, calculating compliance indices and updating dynamic monitoring dashboards. This module centralizes the data sent by Petition 870260011326, dated 05 / 02 / 2026, page 8 / 21 4 / 8 mobile application, allowing input of tests according to the specific needs of the Project and Quality Plan, technical evaluation of results with the possibility of validation by the client, automatic issuance of compliance reports, real-time monitoring of test status (approved, pending or rejected), in addition to providing a management panel with "KPIs (Key Performance Indicators) of quality, cost and deadline, as well as data export to spreadsheets, "Power BI" (Power Business Intelligence) and corporate "ERP" (Enterprise Resource Planning) systems.

[015] Another objective of the invention is to present a technological method of control and management that includes a web-based quality module, configured to enter tests according to the previously established Quality Plan and to approve or reject them based on the results obtained. This module ensures complete traceability, integrity and reliability of information, allowing rigorous control of the adopted technical criteria and a complete history of the evaluations carried out throughout the project.

[016] Finally, the objective of the invention is to present a technological method of control and management that includes a physical-financial management module, which integrates quality approvals with work measurements. This module automatically associates the quality of the services performed with the monthly measurements, ensuring that only technically approved services are considered for payment purposes, reducing potential disputes between the construction company and the concessionaire and enabling more assertive financial projections, including the calculation of the Net Present Value (NPV) of each contract.

[021] The present invention relates to a “TECHNOLOGICAL METHOD FOR CONTROLLING AND QUALITY MANAGEMENT IN INFRASTRUCTURE WORKS”, refers to a technological method (100) applied in infrastructure works (not illustrated) and accessed via mobile application (110) and web platform (not illustrated).

[022] According to the present invention, the aforementioned technological method (100) (see figure 1) is implemented by means of a computer program (PC), executed in a software-as-a-service architecture by a central cloud server (120), allowing simultaneous access by multiple users and different access profiles (PF) of an integrated set of modules (130) that enable the organization, automation and traceability of the digital flow (FD) of the steps of the method (100), the steps being comprised, sequentially and / or in parallel, by registration stage (101), validation (102), technological control (103), quality approval (104) and integration with physical-financial measurement (105), generating automatic outputs (SA) with end-to-end traceability of infrastructure works, all information being stored in a structured way in a database (DB).

[023] The central cloud server (120) of the method (100) hosts application services, business rules and persistence in the automated database (DB) (see figures 2 and 3), with access performed by user profiles (PF) with distinct permissions, comprising at least: field user (A), construction inspector user (B), construction company quality user (C), client quality user (D), construction company measurement user (E) and client contract management user (F) and master user (G) so that each profile has specific levels of insertion, validation, approval and rejection.

[024] The method (100) (see figure 2) is operated by means of a digital flow (DF) of steps implemented from an integrated set of modules (130), Petition 870260011326, dated 05 / 02 / 2026, page 10 / 21 6 / 8 comprising the mobile application module (131), the administrative web module (132), the quality web module (133) and the physical-financial management module (134), which operate in a coordinated manner and in continuous communication with an automated database (DB). These modules are applied sequentially and / or in an integrated manner throughout the stages of the digital flow (DF), as described below: - Registration Stage (101) - The master user (G), through the administrative web module (132), registers the construction company, contractors, projects and users who will have access to the platform; - Information registration stage (102) - Initiated through module (131), executed in the mobile application (110) by the field user (A), comprising the registration (RG) of operational and quantitative data relating to a work front, project or activity performed, including identification of the section or segment, type of service, team, equipment, volumes executed, dates and other attributes necessary for execution control and subsequent measurement. In this stage, the mobile application module (131) automatically associates the georeferencing (GR) to the registration, obtained by device sensors and / or location services, allows the attachment of evidence (AN) and operates with offline validation and subsequent synchronization with the central cloud server (120), preserving the temporal ordering, version control and data consistency. - Validation stage of the work inspection (103) - Executed through the module (131) of the mobile application (110), after data synchronization the registration (RG), georeferencing (GR) and attachments (AN) are analyzed by the inspecting user (B), who verifies the consistency of the information, the conformity of the quantities and the sufficiency of the evidence, issuing a decision of approval (103A) or disapproval (103B). In case of disapproval (103B) (see figure 3), the administrative web module (132) redirects the flow to the previous stage for corrections and additions, maintaining the history of decisions, justifications and responsible parties, and, in case of approval (103A), forwards the flow to the subsequent stage. - Step for attaching quality evidence by the construction company (104) - Performed through the web quality module (133), in which the construction company's quality user (C) receives the data validated by the inspection and attaches the technical documents and the Petition 870260011326, dated 05 / 02 / 2026, page 11 / 21 7 / 8 results of technological control tests, with each test directly linked to a previously recorded activity, ensuring the association between execution and conformity verification. - Customer quality validation stage (105) - Conducted through the web quality module (133), in which the customer quality user (D) technically analyzes the set of documents, evidence and test results presented, and may issue an approval (105A) or rejection (105B) decision according to technical and contractual criteria. In case of rejection (105B) (see figure 3), the web quality module (133) returns the flow to the previous stage (104) for adjustments, additions or resubmission of evidence, preserving the history of the correction cycle and the traceability of information, and, in case of approval (105A), forwards the flow to the following stages. - Measurement review stage by the construction company (106) - Performed through the web quality module (133) and physical-financial management module (134), in which the construction company's measurement user (E) receives the previously approved information for verification and validation of the measurement data, including executed quantities, unit and total values, measurement number and other attributes necessary for invoicing, with such data remaining linked to the execution records and approved tests. - Final contractual approval stage by the client (107) - Performed through the web quality module (133) and physical-financial management module (134), in which the client's contractual management user (F) analyzes the information for final approval, and may issue an approval decision (107A) or rejection (107B). In case of rejection (107B) (see figure 3), the physical-financial management module (134) returns the flow to the measurement review stage (106) for adjustments or corrections, and, in case of approval (107A), the flow is closed with the consolidation of the complete cycle. - Output and report generation stage (108) - Executed at the end of the flow through the administrative web module (132) in conjunction with the physical-financial management module (134), in which the computer program (PC) automatically generates outputs (SA), including the export of measurement spreadsheets and the generation of a consolidated report containing execution data, documents and test results. Petition 870260011326, dated 05 / 02 / 2026, page 12 / 21 8 / 8 associates, ensuring traceability between execution, quality control and invoicing, in order to form a technical-financial dossier suitable for audits, accountability and contractual governance.
