Description. This course aims to Equip you with the advancement in project planning by training you in 4D Planning. 4D Planning is carried out using available schedule in traditional scheduling software and 3D Models developed from various 3D Applications by integrating two of it.

For those who aren't familiar with the concept, 4D scheduling is the bringing together of a 3D model & a project schedule. In simplistic terms, activity bars on a Gantt chart are linked to corresponding elements of a 3D model (including plant & equipment) using additional software.

4D-Planning in construction management is a method of visualizing the schedule [1]. This method is based on Building information modeling (BIM) which is a process that came to revolutionize the work -flow of the Architecture, Engineering and Construction (AEC) Industry.

4D planning is a technique that combines 3D modeling with scheduling and simulation to create a comprehensive plan for a project. It allows project managers and stakeholders to visualize a project from start to finish, including all of the necessary resources, timelines, and dependencies.

What is 4D Planning and BIM? 4D planning is commonly defined as the intelligent combination of a 3D BIM model with the dimension of time (/project programme). This four-dimensional model allows project managers and stakeholders to visualise their project programme in a three-dimensional space.

4D Scheduling is simulating the planning sequence of construction activities and space requirements on a 3D model. 4D adds the time factor of the construction schedule to the 3D model. In simple terms, 4D scheduling is the " visualization of the construction schedule ." [2] That's it!

The author explains the benefits and challenges of using 4D planning for construction projects, drawing on his 35 years of experience as a planner and delay analyst. He suggests some potential reasons for the lagging adoption of 4D planning and some key opportunities for the future. He also provides some tips on how to get started with 4D planning using 3D design models.

Overview. Skills Shortage. Weak Data Visualisation. Digital Transformation Support. Lack of Project Controls Integration.

That's where 4D planning can make the difference. 4D planning provides a time animated video output of the schedule by combining the 3D model with the build sequence required to deliver the project.
