ความสำคัญของคอนสเตรนท์ที่ใช้ในการวางแผนโครงการก่อสร้างอาคารสูง

Abstract

High-rise building construction is a complicated process, subjecting to numerous and variety of constraints. These constraints must be accounted for in the planning process. This research aims at identification and classification of various types of constraint normally encountered in the construction of high-rise buildings. Questionnaires were distributed to construction planers asking for their opinions about the degree of importance and degree of relaxation of these constraints. The results indicate that the top five most significant constraints are : 1) start and finish time. 2) precedence of work . 3) Delivery to construction area.  4) Start and finish date of main activities and 5) construction project cash flow respectively. In addition this research also suggests that all constraints can be structured into six groups. Some guidance have been proposed in order to plan for high-rise building construction project follow the constraints in each group. Realization of grouping can be useful to planners for comprehending project constraints, resulting in a more realistic plan.
