Study of factors affecting delays in delivery of sanitary and fire protection systems for high-rise buildings and extra-large buildings

Abstract

The purpose of this research was to study the factors affecting the delay in the delivery of sanitary and fire protection systems for high-rise buildings and extra-large buildings by using document data collection and interviews with relevant people in the high-rise building project. There are 3 projects of extra-large buildings and the interviewees consist of engineers designers Project Consulting Supervisor project manager Project engineers site engineers draftsman foreman contractors totaling 30 persons. The study of project problems divides the process of installation of sanitation and fire protection systems into 3 steps: 1. Production and preparation process 2. Installation and testing process and 3. Delivery process. Then collect the data from this study, problems found in each step, along with prioritizing the problems according to the time, cost and cost effects that occur, then analyzing the causes and making recommendations. further protection The results of the study found that delay problems that affect the delivery of sanitary and fire protection systems the most in 3 order are 1. Poor control of installation and testing work 2. Coordination between contractors and 3. Making a design to install the wrong job. It has the greatest impact on time, expense and cost in high-rise and extra-large buildings.
