Cascading Risk–constraint Dynamics in Public Construction Projects; a Systems-based Model Integrating Financial, Operational, Strategic and Legal Risk
This study introduces and empirically validates the Cascading Risk–Constraint Management Model (CRCM) using data from 292 public construction projects in Kenya, demonstrating that risks dynamically cascade from strategic governance failures through financial and operational constraints to legal outcomes, with operational risk identified as the strongest predictor of project performance.

Public construction projects are the backbone of modern society, the roads, schools, and hospitals that allow economies to grow and communities to function. Yet, these massive undertakings frequently stumble, plagued by budgets that spiral out of control, schedules that slip endlessly, and contracts that end in court. For decades, experts have tried to manage these failures by treating risks as separate items on a checklist, assuming that a financial problem is just a money issue and a legal dispute is just a paperwork problem. However, a new perspective suggests that this isolated view misses the true nature of the problem. Instead of isolated incidents, risks in construction behave like a connected system where a failure in one area triggers a chain reaction in others. This idea draws on the understanding that complex systems, from ecosystems to organizations, rely on the interaction of their parts, and that the most effective management must account for how a small disturbance can ripple through an entire structure.
In a recent study focused on public construction projects in Nakuru County, Kenya, researchers set out to test this idea of interconnected risk. They examined 292 specific projects, ranging from road infrastructure to health facilities and market buildings, to see how different types of danger actually interact. The team proposed a new way of looking at these projects, suggesting that risks do not happen in a vacuum but rather cascade down a hierarchy. They hypothesized that high-level problems in governance and strategy would first create financial constraints, which would then disrupt the day-to-day operations of the construction site, and finally, these accumulated operational failures would erupt into legal battles. By surveying project managers, engineers, and accountants involved in these works, the researchers gathered enough data to map these relationships and see which factors truly drove project success or failure.
The findings revealed a clear and predictable path of failure. The study confirmed that when strategic planning is weak or governance is poor, it directly leads to financial trouble, such as delayed funding or budget mismanagement. These financial issues, in turn, act as a bottleneck that strangles the physical work on the ground. When money is late or scarce, procurement slows down, contractors cannot mobilize, and the daily rhythm of construction breaks. This operational breakdown is the most powerful predictor of a project's poor performance, meaning that the actual execution phase is where the damage becomes visible. Finally, when these operational problems pile up beyond a certain point, they trigger legal risks. These legal issues, such as contract disputes or regulatory violations, often lie dormant until the operational failures reach a critical mass, at which point they activate rapidly and can bring a project to a complete halt.
The researchers found that while all four areas—strategy, finance, operations, and law—play a role, they are not equal in their immediate impact. Operational risk was identified as the strongest direct cause of poor project performance. This suggests that the moment a project starts to struggle with its daily tasks, the likelihood of failure skyrockets. Financial risk acts as a critical constraint that intensifies these downstream challenges; even a modest funding gap can destabilize the entire operation. Strategic risk shapes the environment in which the project exists, setting the stage for potential issues, while legal risk emerges as a latent outcome. It is important to note that legal risk often appears less significant in statistical averages because it remains inactive in many projects. However, the study indicates that when it does activate, it is a catastrophic event that can undo years of work, making it a severe tail risk that is difficult to contain once triggered.
This research challenges the traditional method of managing construction projects, which often treats risks as independent variables to be checked off one by one. The evidence from Nakuru County shows that risks are deeply coupled, meaning a problem in one domain inevitably transmits pressure to the next. The study supports a model where project managers must view their work as a dynamic system. To prevent a total collapse, they need to monitor the early warning signs of operational disruption, which often stem from earlier financial or strategic weaknesses. By understanding that a governance failure can eventually lead to a lawsuit, or that a budget delay can stop a school from being built, public sector organizations can shift from reacting to crises to proactively managing the flow of risk through the entire system. This approach offers a more realistic path to delivering the infrastructure that communities rely on, moving beyond simple checklists to a deeper understanding of how complex projects truly function.
