Tartalmi leírás:
Modular construction is well known for its ability to provide numerous productivity and overall cost benefits over the conventional stick-built method through sophisticated off-site environments. However, although the advantages of modular construction are recognized, it is still considered a secondary means for delivering construction projects in the U.S. Consequently, modular projects often fail to achieve full benefits due to stakeholders’ lack of expertise and experience. Existing studies examined the on- and off-site modular process optimization, whereas module transportation is relatively unconsidered. Among the modular benefits, the expedition of construction project schedules is paramount as it directly impacts the project delivery time. A meaningful portion of time for modular projects is allocated for transporting the completed module to its final installation spot, and its optimization will contribute to the project schedule expedition. Accordingly, this paper, through the examination of the volumetric modular house transportation project, will identify potential schedule-delaying elements and recommend corrective measures that will minimize, if not eliminate them. Transportation time stamps were collected with the two sets of 2 channel dashcams installed inside the module and divided into three stages (Lifting, Transporting, and Offloading). The modular project took two days to complete, going over the anticipated 10-hour duration. The most impactful schedule-delaying elements originated from the use of lumber stacks as temporary supports for hydraulic jacks and disconnected tandem axle dollies for the bogey support system. The analysis conducted by this paper will help industry stakeholders eliminate the schedule-delaying elements of modular transportation projects and achieve the full benefits of modular construction.
