Fig. 1

a–c, Survival curves for each analysis type and event (completion of NEPA (a), completion of contract (b) and completion of first activity (c)) along with their 95% confidence interval (shaded regions). Horizontal bar charts depict the descriptive median time to completion (dark shaded region) and the action’s planned duration (light shaded bars), or lifespan, along with the ±1 standard deviation for the descriptive median time to completion. Median probabilities are used to calculate the percentage of time spent on a given task as a proportion of planned lifespan. Median probabilities are 0–4 months longer than descriptive medians. Descriptive summaries of time to completion and lifespan are provided in Supplementary Table 1.
