Query: Uncovering the fragility of large-scale engineering project networks   Engineering projects are notoriously hard to complete on-time, with project
delays often theorised to propagate across interdependent activities. Here, we
use a novel dataset consisting of activity networks from 14 diverse,
large-scale engineering projects to uncover network properties that impact
timely project completion. We provide the first empirical evidence of the
infectious nature of activity deviations, where perturbations in the delivery
of a single activity can impact up to 4 activities downstream, leading to large
perturbation cascades. We further show that perturbation clustering
significantly affects project overall delays. Finally, we find that poorly
performing projects have their highest perturbations in high reach nodes, which
can lead to largest cascades, while well performing projects have perturbations
in low reach nodes, resulting in localised cascades. Altogether, these findings
pave the way for a network-science framework that can materially enhance the
delivery of large-scale engineering projects.
