Factors Affecting Construction Delay: A Case Study of the Metropolitan Rapid Transit Pink Line (Khae Rai - Min Buri)

Abstract

The Metropolitan Rapid Transit Project is a large construction project with high resource usage in both funding and other resources. The frequent occurring problem is the delays in the construction of the project which cause the project to be completed according to the contract. The objective of this research was to analyze various factors affecting the delay of the train construction project operation as well as finding a way to control the said factors in order to complete the construction as scheduled. The researcher has chosen to study the construction of the Metropolitan Rapid Transit Pink Line Pink Line (Khae Rai - Min Buri) using a questionnaire to explore the factors affecting the duration of the project construction of the contracting company using the Taro Yamane equation with the samples of 82 people. The statistical variables analyzed were frequency, percentage, mean, standard deviation and rank the severity of each factor The analysis shows that the factors affecting the construction delay of the Pink Line Electric Train Project (Khae Rai - Min Buri), the top 5, in descending order as follows: 1. Shop Drawing approval is delayed 2. The delay from the owner in answering questions from the contractor 3. The issuance The order to change the details of the designs used in the construction and schedule details 4. The use of personnel is not suitable for the job and there are not enough personnel 5. The lack of construction labor In terms of the impact on the project Overall is at a medium level. And the frequency of the projects is at a low level Basic prevention guidelines Is to bring modern technology to help in construction in order to reduce work steps The recruitment of personnel should be suitable for the job type, with the personnel very important to succeed as planned.
