Abstract

Construction lift planning is a key factor for successful project completion in tall building construction. It is because too few hoists can cause productivity losses by failing to hoist resources in a timely fashion, and too many hoists can incur unnecessary costs when hoists are idle. Planning for construction lift arrangement usually performed by simple formulas, which is only used to calculate the adequate number of lift. And, scheduling for operated durations of lifts has no systematic method. So, a significant amount of decision making in construction lift planning depends on the intuition and rule of thumb experience of the planner. Consequently, this method carries the risk of making inappropriate decisions which potentially cause problems such as cost increases and duration delays. Therefore, the purpose of this paper is to propose construction lift planning model using discrete-event simulation technique for supporting planners to create an optimal plan based on the objective assessment for tall building construction. To verify the applicability of the proposed model, it was applied to an actual tall building construction project in Korea. In the result, the proposed model showed a more optimal arrangement of lift that offered reduced cost than that of the simple formula, and reasonable durations for each lift operation
