During a risk identification process in a construction project, the lack of space to install air conditioners is raised as a risk with high impact. Which is an example of an early risk trigger?

An early risk trigger is a warning sign or condition indicating that a risk is likely to occur. In this context, the risk is the "lack of space to install air conditioners." The "potential need to share the space with other machinery" is a condition that would be identified during the planning or early design phase. It serves as an early warning that the allocated space may become insufficient, allowing the project team to proactively develop a response before the installation work begins and the risk materializes.

B. Receiving different equipment is a trigger that occurs immediately before installation, not an early warning sign from the planning stage.
C. A time delay is a potential consequence or impact of the risk occurring, not a trigger that warns of the impending lack of space.
D. A quality nonconformance issue is identified during inspection after installation, making it a lagging indicator, not an early trigger.

Section 11.7.2.1, Project Documents Updates: This section discusses updating the risk register with information including "triggers." It defines triggers (or warning signs) as indicators that a risk has occurred or is about to occur. Option A is a classic example of a condition that signals a risk is about to occur.

Section 4.2.2.3, Risk Triggers (p. 31): "Risk triggers, sometimes known as risk symptoms or warning signs, are events or conditions that indicate that a risk is about to occur or has occurred... Identifying potential risk triggers during the risk identification process can improve the ability of the project team to monitor risks." This directly supports identifying a condition like "potential need to share space" as a trigger.

This paper discusses identifying risks from various sources. An early warning sign, such as a constraint on a physical resource (space), is a key input to the risk management process. The potential conflict over space (Option A) is an identifiable condition that acts as such a warning.
