Technical audit is a detailed assessment of the conformity of a construction or contracting contract with what was hired. It analyzes the scope, the project, materials, accounting information, attendance to norms and seeks to reduce failures throughout the development of the work.

Unlike a simple survey, this audit has technical and investigative character. Its main objective is to verify that what is being executed really follows the version of the project agreed between the parties, the technical specifications, the contract and budgets.

Performed by engineers or specialized professionals, the technical audit evaluates not only what was done, but also the construction methods used, the conditions of the site, the proper use of the team and the decisions made during the work.

Main benefits of technical audit in the works

Implementing technical audits contributes directly to the quality control and safe advancement of work in the construction site. Among its main benefits, stand out:

• Prevention of rework : When identifying failures still in execution, it is avoided the need to correct errors later.
• Operating Cost Reduction : Fewer errors mean less waste of material, time and labor.
• Structure Safety : Technical analysis reinforces compliance with the standards and ensures a safer construction.
• Avoid non -compliance with legal compliance : anticipates problems related to ABNT technical standards, environmental legislation and occupational safety.
• Transparency and Governance : Allows managers, investors and customers to access reliable reports on the progress of the work.

When and how to perform a technical audit?

Technical audit can be applied at different phases of the work: before the beginning, during execution and after completion. Each phase has its own goals:

Technical audit before execution (pre-work)

This type of audit analyzes the compatibility of projects (architectural, structural, hydraulic, electric), the viability of execution and whether the companies involved have a technical capacity to perform the service.

The existence of licenses, permits and compliance with ABNT standards in planning is also verified.

Audit during the work (follow -up)

It is the most critical phase of construction, as it involves the constant verification of the following points:

• Public and Private: If rules and contracts are being followed;
• Technicians: compliance with project specifications and constructive techniques;
• Budgetary: If spending is expected;
• Schedule: Compliance with the goals established until the audit.

Periodic audits during execution are fundamental to ensure efficient driving of the responsible team and keep the work in the right direction.

Closing Audit (Post-Obra)

Made with the construction already completed, this audit attests (or not) that everything was performed according to the technical, contractual and regulatory requirements.

It occurs at this stage, for example:

• Pending deliveries;
• Compliance with original projects;
• Structure and facilities;
• Electrical, hydraulic and safety systems;
• Final documentation, such as the conclusion auto.

Tools and methodologies applied in a technical audit

To gain efficiency, many audits have methods and technologies that facilitate data collection and technical analysis.

Digital Systems Monitoring

Specialized software solutions in civil construction allow field records, schedule monitoring, material control and immediate documentation. Among the most used are:

• BIM (Building Information Modeling);
• ERP for construction (cost and material management);
• Inspection mobile applications and technical checklist.

Photographic survey and digital records

During the visits, auditors record each stage of the work through photos, videos, drones and digital notes. These materials help in generating technical reports.

Normative checklists

Checklists based on technical standards (such as NBR 5674 or NR-18) determine objective criteria to evaluate from finishes to electrical installations.

These checklists vary according to the type of work (residential, industrial, infrastructure) and can be adapted to the reality of the project.

ISO 9001 and PBQP-H application

Companies that follow Quality Management Systems based on ISO 9001 or adhere to the Brazilian Habitat Quality and Productivity Program (PBQP-H) also perform technical controls that resemble formal audits.

Main failures and technical risks that the audit detects

The technical audit contributes to the identification of various flaws in works - some subtle and some of high impact. Among the most recurring:

• Incompatibility between projects: disagreements between structural, electrical and hydraulic plant;
• Materials outside specifications: use of products with quality lower than expected;
• Incorrect execution of foundations or masonry;
• Lack of PPE and non -compliance with safety standards;
• Not justified delays in the schedule;
• Irregularities in measurements and payments for unsuccessful services;
• Variations in prices and quantities of services;
• Problems in technical installations, such as electric and HVAC.

By anticipating these problems, it is possible to implement fast corrective actions, avoiding accumulative effects on the advancement of the work.

How can the construction company implement a technical audit routine?

To ensure that audits are effective, it is not enough to do so on time. It is necessary to create an internal management structure that allows recurring monitoring of the technical quality.

Here are some recommended actions:

1. Designate technical responsible for audits, with autonomy to investigate and request corrections.
2. Include in the schedule of the work fixed dates for technical audits , preferably at the end of each relevant step (foundation, structure, finish, etc.).
3. Use digital works control tools , integrating schedules, documents and physical measurements.
4. Invest in the training of the technical team , reinforcing good constructive practices and knowledge of technical standards.
5. Promote the culture of transparency between engineers, managers, workers and contractors.

Technical audit as a tool for more efficient, safe and sustainable works

Technical audit in works is a tool that goes far beyond compliance verification: it represents a strategy for protecting failures, delays and waste that threatens the success of construction enterprises.
