The 10 most common quality control failures in construction and infrastructure projects

Content in collaboration with Vi-Soft

Construction and infrastructure companies in Israel are facing significant losses as a result of malfunctions and defects, which stem, among other things, from failure to meet quality goals and operational failures. In the first quarter of 2024, approximately 30% of the construction companies in the Tel Aviv Construction Index recorded a loss – an increase compared to an average of 20% in the previous three years, with project delays and defects being among the main reasons for this. In 2023 alone, 470 construction and infrastructure companies found themselves in cash flow distress, and estimates indicate that an additional 680 contractors are expected to find themselves in a similar situation due to various malfunctions, delays, and poor project management. Beyond direct losses, significant construction defects sometimes also lead to compensation estimated at hundreds of thousands and even millions of shekels per project, for depreciation and significant infrastructure repairs. In this challenging reality, the responsibility of quality control and quality assurance personnel becomes especially critical as the gatekeepers of each project. Quality control and assurance personnel are required to identify root causes in a timely manner, establish standards It is imperative to instill a professional culture and ensure that each step is carried out optimally and without compromise.

Quality control and quality assurance are a cornerstone of any serious construction or infrastructure project. However, even in projects that are considered meticulous and uncompromising, similar failures repeatedly emerge, causing delays, unnecessary financial costs, a decrease in product quality, and in the worst cases, even real safety hazards. Here are the ten most common failures in the field:

1. Lack of quality planning already in the initial design

Quality starts long before you arrive on site: it is imperative to define quality goals, clear criteria, and regulated work procedures right from the planning stage. When these aspects are postponed to later stages, the price comes in the form of expensive repairs, delivery delays, difficulty tracking performance, and failure to meet customer requirements.

2. Quality checks by an unqualified party

Often, field inspections are left to inexperienced teams, hoping that they will “do the best they can.” In practice, these inspections often end up confirming defects. When defects are discovered at a later stage, all that remains is to destroy or dismantle expensive materials, and the repair adds cost and time.

3. Lack of organized documentation of the tests

Every inspection, no matter how small or routine, must be documented – including results, certificates, photos, signatures and dates. Without professional documentation, it is impossible to prove compliance with requirements, resolve disputes or learn lessons for future projects. Systematic documentation is essential as it provides a high-quality “safety net” and allows for relevant professional accountability where a dispute arises.

4. Relying on final tests only

This is a critical mistake: You need to differentiate between in-process testing – which allows you to identify problems and address them immediately – and final testing – which actually comes too late. To avoid costly surprises and frequent delays, it is imperative to plan quality control points (Quality Gates) in advance, and perform measurements in stages, according to key milestones.

5. Lack of training and direction for implementation teams

Sometimes it turns out that construction teams don’t really understand the requirements of the standard or the subtleties of implementation. In this situation, the risk of errors and multiple defects increases. Professional training, document summaries, information sessions, and daily digital support dramatically improve the level of execution and compliance with standards.

6. Insufficient learning from previous projects

Recycling errors is a symptom of systemic failure. Organized reporting, documentation of failures and implementation principles, and knowledge transfer – all of these prevent the repetition of errors, reduce failures, and raise the bar for project professionalism.

7. Improper selection of suppliers and raw materials

Hasty or uncontrolled selection of suppliers/materials often leads to defects, malfunctions, and loss of customer trust. A rigorous testing system must be carried out, accurate bills of quantities must be drawn up, approvals must be checked in advance, and raw materials and suppliers must be monitored regularly.

8. Dependence on a single person – risk of losing knowledge

When the critical knowledge and history of quality resides with only one person, any departure of such a role holder or change in their role definition results in the loss of valuable information and the painful learning process starting all over again. Digital data collection that is centralized in one place, accessible and transparent to everyone, is an invaluable factor.

9. Lack of use of advanced digital tools

Manual quality management based on notebooks or scattered Excel files is no longer suitable for the world of large-scale infrastructure projects. The use of digital tools is essential. Such tools centralize all the details, create immediate accessibility, produce smart reports in real time, and prevent errors caused by a lack of synchronization.

10. Failure to correctly identify the critical path in the project

The critical path is the chain of tasks that, if not completed on time, will delay the entire project. Failure to identify them in advance will cause a “domino effect” and disrupt schedules. Only advanced software can graph this path and automatically alert you when something goes wrong.

Indeed, multiple failures in construction and infrastructure projects are a common phenomenon that takes a heavy toll on the project budget, the developers, and the executing companies alike. Any quality failure – whether it is a design flaw, a lack of documentation, or the use of unsuitable materials – can lead to delays, budget overruns, damage to customer trust, and even a real safety hazard. Beyond these immediate consequences, the accumulation of defects establishes a negative image in the entire industry and harms the stability of companies, their ability to win future tenders, and their long-term profitability.

The challenge is clear and comprehensive. Most of the problems stem not from neglect but from a lack of proper infrastructure. The good news is that there is a digital tool that provides a solution to all the weaknesses mentioned, and an advanced and comprehensive version of the old Vi-Soft software was recently launched.

For those who don’t know yet, Vi-Soft is a dedicated digital management system that allows you to define quality already in planning, easily perform and document tests, and maintain continuity of professional knowledge even when teams change or when the project becomes complex.

Vi-Soft generates reports and alerts, enables control with suppliers, manages approvals, documents raw material ordering and usage, and consolidates test history. The software essentially connects all stakeholders – project managers, contractors, quality controllers, quality assurance managers, consultants, engineers, and more – into one clear and transparent screen for all parties.

Setting clear goals and recording documents and procedures is easy with Vi-Soft. The software enables systematic and orderly documentation management, including uploading images and digital documentation from the field. It assists in producing quality reports with an easy-to-use interface and focused accessibility for all teams, ultimately providing active, rather than reactive, control.

In conclusion, in a complex and highly competitive era, effective quality management is not a luxury, but a basic requirement. Choose the control and management tool that will allow you to manage quality, documentation and professional production processes in the best possible way. This way you will ensure that your next construction project will not only be efficient, but also safe, documented and appreciated by clients and professionals alike.
