Exploring Simultaneous Effects of Delay Factors in Precast Concrete Installation
Delays in the installation process of precast concrete (PC) components significantly impact the project execution. However, traditional scheduling and risk assessment methods fail to consider this process complexity and uncertainty adequately. With a systematic approach, this study analyzed complex delay mechanisms in the PC installation of three component types (columns, beams, and slabs) using 1881 observations across five work steps. Specifically, this study used k-means clustering to divide the observations into groups with certain characteristics. These groups were assessed quantitatively using the delay intensity metric. Based on the assessment, this study revealed six severe delay paths for different component types, which may combine to generate severe combinations of delay factors, considering factors such as the component size, wind conditions, worker availability, and installation location. This research contributed to PC construction management by presenting a systematic analysis of delay factors and by proposing specific severe delay paths during PC installation, offering project managers a basis for schedule optimization and risk management.
