Introduction

It is well known that projects are customized, but quality must be standardized. That said, how can we ensure that particularities do not affect the quality of the final product?

Therefore, the answer to this question lies in diligence. This service consists of specialized technical supervision, which aims to ensure that a project is executed in accordance with technical requirements and regulatory standards, within the specific needs of the client. In addition, diligence encompasses a set of actions that provide the project with the necessary quality standards for safe construction and operation, as well as adequate planning that generates productivity and on-time delivery. Figure 1 presents a typical flowchart for ensuring the quality of a project through diligence.

Certainly, large projects with large investments require detailed planning. In addition, diligence can also be a tool used to control the progress of the planning stages, through Project Quality Certification (PQC), manufacturer certification, manufacturing inspection, and monitoring of assembly execution.

How does Kot work in due diligence?

Currently, Kot's involvement in the process can range from the beginning of the project to final delivery. Some of these services will be discussed below.

Due diligence at project stage

Basic engineering and project certification:

First, the process begins in the basic engineering phase, where the fundamental concepts of the project are defined. At this stage, engineers perform preliminary analyses to determine the technical feasibility of the project. It is crucial to understand the project requirements and constraints, identifying performance objectives and safety criteria. During this stage, technical specifications, material compatibility, expected loads, and other essential variables are evaluated. Thus, this stage involves reviewing every aspect to ensure that the basic design is solid and well-founded.

Above all, quality certification plays a key role in any industry, ensuring that products, processes, and services meet predefined standards and comply with specific requirements. In the field of mechanical and civil engineering, quality certification of designs is essential to ensure the safety, efficiency, and functionality of structures and mechanical systems.

Audit by computer simulations:

In this context, computer simulation is a valuable tool in project development. It allows the structural behavior of the project to be analyzed under various conditions, extreme loads to be simulated, different operating scenarios to be tested, and areas for improvement to be identified. For example, in structural projects, simulations using the finite element method can reveal areas with stress concentration, excessive vibrations, unacceptable deformations, etc. Auditing using computational methods enables the early detection of problems, before actual construction, saving time and resources and mitigating risks.

Evaluation of the assembly sequence and proposal of improvements and reinforcements:

One aspect that is often overlooked is the assessment of the assembly sequence. The way in which components are assembled and connected can influence the stability and safety of the structure. In project due diligence, evaluating the assembly sequence makes it possible to anticipate potential difficulties or risks associated with the construction. In addition, opportunities for improvement can arise during this process. Using the knowledge accumulated during assembly analysis, engineers can propose design changes to facilitate construction, reduce costs or increase efficiency. Standards also stipulate that the combinations and loads on a structure must be verified during construction.

Due diligence in the manufacturing phase

Supplier qualification:

Supplier qualification is an essential step in project diligence, as it ensures that the manufacturing company has the technical capabilities and resources necessary to meet project requirements. This involves careful evaluation of the supplier's experience, production capacity, quality systems, delivery history, and compliance with applicable industry standards. On the other hand, selecting unsuitable suppliers can result in delays, poor-quality products, and even safety risks.

Raw material validation:

Secondly, raw material validation is another critical step in the manufacturing phase. Quality materials are essential to ensure the integrity and durability of the structure. At this stage, the storage locations and methods are checked for suitability, and tests and analyses are carried out to verify that the materials supplied meet the required technical specifications and standards. This includes testing chemical composition, mechanical properties, and microstructural analysis. Raw material validation is essential to prevent premature failure due to inadequate materials, from the primary structure to the specific type of coating.

On-site monitoring of production with Non-Destructive Testing (NDT):

On-site production monitoring is a stage in which engineers and/or inspectors are present at the manufacturing site to closely monitor the process. This physical presence allows for real-time assessment of operations, identifying possible deviations and problems that may arise during production. In addition, non-destructive testing (NDT) is used to verify product quality without damaging them. This includes techniques such as ultrasound, magnetic particles, and penetrating liquids for metals, and ultrasound, tomography, pacometry, and GPR for concrete structures. Thus, NDTs help detect internal or surface defects, certifying that products are free of imperfections that could compromise their Structural Integrity.

Diligence in the assembly phase

Finally, in the assembly phase, when the project takes physical shape, diligence plays an indispensable role in ensuring that construction proceeds accurately and safely.

Engineering support during assembly:

Engineering support is a central element in the process of setting up mechanical and civil projects. It involves providing technical guidance and assistance to the professionals involved in the construction. This can include the creation of detailed assembly manuals, component positioning diagrams, welding instructions and more. Engineering support validates that assembly is carried out in accordance with project specifications and established quality standards. It also helps to avoid errors that could lead to rework, delays, additional costs or even accidents.

Monitoring assembly and lifting:

Similarly, monitoring assembly is an activity that involves the presence of engineers, inspectors, or specialized professionals at the construction site. The goal is to ensure that assembly is carried out properly, safely, and in accordance with the design. During this phase, visual checks are performed, as well as dimensional checks, monitoring of compliance with the previously defined procedure, among other deviations from the original design. In addition, in the case of hoisting heavy or complex components, monitoring becomes even more critical. Ensuring that hoisting procedures comply with safety standards and that the equipment used is adequate are key points in preventing accidents and ensuring the integrity of the structure.

The importance of due diligence for mechanical and civil engineering

Safety: Mechanical and civil engineering often deals with high-risk situations, where mistakes can result in serious accidents, damage to property or even loss of life. Due diligence aims to identify and mitigate these risks, whether through simulations, inspections, tests or supervision of critical processes. By making sure that all aspects of the project are in line with safety standards, due diligence contributes to preventing incidents and protecting the health and well-being of everyone involved.

Durability: Engineering projects are designed to last for many years. Certifications and inspections ensure that products adhere to specifications and are suitable for the operating conditions of the asset or structures.

Compliance with standards: Technical standards and regulations are established to provide quality and uniformity in industry. In the field of engineering, quality and compliance are crucial to avoid failures, rework and financial losses. Due diligence validates that all aspects of the project, from the selection of materials to the execution of the construction or production processes, comply with standards and technical specifications. This involves checking the quality of materials, the correct application of construction and manufacturing methods, and carrying out tests to ensure that the end result meets the established standards.

Efficiency: Due diligence is not just about quality and safety; it also plays an important role in optimizing processes and reducing costs. By identifying inefficiencies or problem areas during the different phases of the project, due diligence allows for the implementation of improvements that can save time and resources. This is particularly relevant in engineering projects, where small changes can lead to big gains in efficiency and savings.

Meeting deadlines: Engineering projects often have tight deadlines that must be met to avoid delays and negative impacts on schedules. Due diligence helps monitor the physical progress of the project and identify potential obstacles that could affect deadlines. By anticipating problems and proactively resolving challenges, due diligence contributes to on-time project delivery.

Reputation and trust: Companies that obtain manufacturer certifications demonstrate a commitment to quality and excellence. This helps build a solid reputation and establishes the trust of customers and partners.

Conclusion

In conclusion, diligence is an indispensable practice in mechanical and civil engineering, offering a set of strategies and processes that ensure quality, safety, and efficiency at all stages of a project.
