Abstract
In construction, schedule mistakes causing delays beyond substantial completion dates cost contractors expensive liquidated damages. Hence, several industry guidelines, such as the DCMA's 14 point assessment, define schedule quality and offer systematic methods for ensuring it. These guidelines list “logic” as an essential control metric, and they require planners to ensure their schedules are free of missing or wrong logical dependencies. Checking the logic requires extensive construction domain knowledge, and planners perform it entirely manually as there are no available software solutions that support it. This paper offers a novel machine learning-based solution that learns construction scheduling domain knowledge from existing records completely automatically and applies it to validate the logic in input schedules achieving an F1 score of 88.3%. Furthermore, we tailor our method to use the learned knowledge to schedule a list of unordered activities. The details of the method, experimental results, benefits, and limitations are discussed.
