Abstract
Modular construction enables delivery of a building as an assembly of a set of modules manufactured offsite in a controlled manufacturing facility environment. Unlike stick-built practices, modular construction enables higher schedule control of construction projects due the inherent concurrency of offsite and onsite construction operations. Literature provides simulation-based scheduling methods that integrate offsite and onsite construction activities. These methods, however, depend largely on availability of data such as productivity rates for offsite and onsite activities. This paper presents an alternative BIM-based framework that integrates linear schedules of onsite and offsite construction operations in a manner that synchronizes work progress of these operations. The proposed framework considers limited capacities of storage areas in the manufacturing facility and on site as well as, the availability of trucks for delivering the fabricated modules from manufacturing facility to the jobsite. The use of BIM provides visualization capabilities for the integrated schedule and allows for monitoring simultaneously the work progress of offsite and onsite activities. Conclusions are drawn concerning the suitability of developed framework for integrated scheduling of modular construction projects.
