Abstract
Building projects can be divided into residence, office and factory according to their functionalities. Construction teams are organized to complete the two major tasks of the projects: civil work and HVAC. These two tasks are finished by the general contractors and their subcontractors. Since the teams involved in the projects are numerous, the interface problem between the contractors of civil work and HVAC becomes a critical issue in the construction phase and affects the progress of the project. Due to the uniqueness of each project in design and construction methods, there are no standard scheduling rules or processes to be followed. In current practice, the quality of scheduling is based on engineers’ experiences. If the experience cannot be delivered from project to project, a mis-order work schedule might happen and result to progress delay. In addition, HVAC activities are embedded in the civil activities in most cases. Appropriate management mechanism is desirable to handle the interference problems..
The objective of this research is trying to reduce the probability of mis-order scheduling. Elevator construction is taken as a case study to develop the civil and HVAC scheduling guidelines. Through literature review, interview with practitioners, and site investigation, the necessary activities for civil and HVAC scheduling are identified respectively and an ideal schedule is suggested. Then a 4D model is developed based on the ideal schedule to check if this schedule is really “appropriate”.
The ideal activities of civil work and HVAC identified for elevator construction and the guidelines for simultaneous civil and HVAC scheduling can contribute to the engineers with little scheduling experience. Following the steps, the efficiency of civil and HVAC scheduling and the quality of the project management can be improved.
