Traditional project schedule documents can be complex and subjective based on the reader. By merging the 3D model with project schedule activities, the planned construction sequence comes to life through 3D images and videos. Many clients find value in using this visual scheduling technique in conjunction with traditional project scheduling techniques. 4D Scheduling
ACTION
RESULT
CREATE EMJ obtains or creates both a detailed 3D model and a project schedule showing the proposed sequence of construction. VISUALIZE Objects within the 3D model are linked to the schedule activities using an associative database software. Once linked, the result can be played to show a step-by-step construction sequence of the planned building. INTERACT & ANALYZE The team plays the sequence for all team members in an interactive setting which encourages informed decisions in the planning process.
EMJ shares information with jobsite staff and subcontractors to visually communicate expectations. The team can use the 4D study as a one-time exercise at the beginning of the job, or it can be updated incrementally as the project progresses.
BENEFITS The process removes ambiguity of the project schedule and all parties are held accountable for their work.
Alternate schedules are quickly visualized and analyzed.
Project stakeholders participate in schedule reduction suggestions while viewing the 4D schedule video in an interactive setting.
Value
In a survey of construction industry professionals, over 300 respondents reported an average schedule slippage of 3.64% on their construction projects.
