| dc.description.abstract | The compressed project schedule for constructing a new plant necessitates the establishment of an electrical and plumbing schedule based on overall progress, indicating that the preference ranking of influencing factors is critical for management. The purpose of this study is to establish the preference ranking for electrical and plumbing engineering projects based on construction phase prioritization using the Analytic Hierarchy Process (AHP). In the literature review, six dimensions and 25 criteria that influence the overall progress of electrical and plumbing engineering, including the sequence of construction activities and decision-making, are outlined. A questionnaire survey using AHP was conducted among 12 experienced professionals, including project designers, civil engineering experts, mechanical and electrical professionals, site supervisors, electrical and plumbing team foremen, and senior electrical and plumbing practitioners, with most of them having over 15 years of work experience. The consistency index (CI) was found to be 0.09, and the consistency ratio (CR) was 0.08, both of which are less than 0.1. The findings show that (1) the preference ranking of factors in the order of Design and Review > Foundation Construction > Structural Construction > Operation and Testing > Decoration Construction; (2) in terms of system stages, CI = 0.08, and the CR = 0.06, both of which less than 0.1. Therefore, the preference ranking results in the following order: Project Condition> Equipment Installation > Electrical System > Water Supply and Drainage System > Fire Protection System > Air Conditioning System. By utilizing AHP analysis and calculating the weights for each activity, the electrical and plumbing schedule control table can be established based on the preference ranking. Project activities remain under control until their completion or until they no longer impact the overall progress. | en_US |
