Abstract
The project duration can be shortened by overlapping construction activities. However, the continuous changing of the environment tends to cause problems such as rework and the failure of the overlapping plan. In order to solve these problems, communication strategies for the overlapping of dependent activities are first introduced and optimized from a revenue perspective. We first consider the different maturities of upstream activity before and after the overlapping, the downstream sensitivity which is decided by involving communication strategies, and the learning and error‐correcting ability of workers. Then, the overlap and communication strategies are decided by calculating the maximum revenue using Monte Carlo simulation and MATLAB based on overlap cost, communication cost, rework cost, and reward amount. Finally, the algorithm and BIM are combined to provide a visual overlap plan and dynamic control platform framework. This research is valuable for practitioners as it provides a dynamic overlap plan which can maximize the revenue in changing the environment and ensure the duration of the project. This research also provides researchers a new insight into combining overlap problems and BIM technology.
Highlights
Compressing project duration, one of the most important ways to optimize project schedule and obtain the investment benefits [1,2,3], has been intensively investigated
If applying overlapping strategy between two activities in an unappropriated time, for example, the upstream activity information is incomplete, the resources are in a shortage, or the working surface is insufficient, it is likely to increase the risk of rework [2, 7, 8], cost [9], and the failure of schedule plan [2, 7]
If two activities are interdependent (Figure 1(c)), can the changes in upstream activity bring the rework risk of downstream activity, and the changes in downstream will cause the delay of upstream activity; that is, the iterative influence. erefore, for the activities which can influence each other, namely, the latter two types, controlling the amount of change or reducing the impact of them is a critical factor for project success
Summary
Compressing project duration, one of the most important ways to optimize project schedule and obtain the investment benefits [1,2,3], has been intensively investigated. If applying overlapping strategy between two activities in an unappropriated time, for example, the upstream activity information is incomplete, the resources are in a shortage, or the working surface is insufficient, it is likely to increase the risk of rework [2, 7, 8], cost [9], and the failure of schedule plan [2, 7]. It will reduce the potential revenue of the project entering the market. The article ends with conclusions, contributions, limitations, and future research
