The implementation of non-unit-based scheduling method in a housing project

Abstract

Abstract Of the various types of construction projects, contractors often encounter repetitive projects. Many methods have been used for scheduling repetitive projects, but most repetitive scheduling methods have the basis that they are composed of many identical production units. Scheduling repetitive projects using unit-based methods has several constraints such as modeling and applying them to construction projects requiring simplification of repetitive activities to have a single duration and in a fixed production sequence. Therefore, a non-unit-based scheduling method is developed. In this analysis, the project data was obtained from a housing project. Based on the data, an analysis was conducted to look for the effect of changes in the factors used in the non- unit-based scheduling method on the final duration of the project. From the analysis it was found that the factors used in the non-unit-based scheduling method such as duration, priority order of activities, number of resource groups, and relationships between activities greatly influenced the final duration of the project.
