Key Benefits of 4D BIM

Four-dimensional Building Information Modelling or 4D BIM helps to incorporate time as a fourth dimension in the design model, which helps to make it possible to sequence the construction process throughout time. The 4D BIM helps to support the schedule optimisation process, the detection of design conflicts and also helps to anticipate any kind of project delays or conflicts.

Thus, the 4D BIM technology helps to improve the project planning and management process. The 4D BIM technology helps to combine 3D BIM design models along with the time and scheduling process, which helps to visualise each stage of the design and construction project. Thus, the 4D BIM technology helps to show the importance of each part to the whole design project.

Discuss the key advantages of the 4D BIM

Improving project comprehension

With the help of the visualisation feature of the 4D BIM technology, the project stakeholders can see what comes next, along with the look-ahead scheduling process. This feature helps to add real-mapping data into the project plans and schedules, thus providing a more realistic picture regarding the future of the design and construction project. The 4D BIM technology helps to provide a better understanding of the project, which enables the remote stakeholders to get more accurate project insights. Thus, all project team members are ready for upcoming installations and find project errors in the schedule before causing blunders.

Saving project time and cost

The 4D BIM technology enables access to the project information by all project team members, which allows the project stakeholders to stay one step ahead of the actual construction stage, thus saving time and cost for all project participants.

Reducing project clashes

The 4D BIM technology helps to produce data on the construction product timetables and helps to develop a graphic, which helps to cover the duration of the construction and installation process, the srying and mixing periods and links to other goods. Thus, the clashes between the project elements have been detected and resolved at the early stage of the design and construction project, as well as reducing the risks of reworks or project delays.

Optimising project scheduling

With the help of the 4D BIM technology, the project managers and stakeholders can also optimise the project schedules and can identify those areas that may face project delays. In addition, the project stakeholders are also allowed to verify the process and confirm if the project is being sequenced correctly or not. The project scheduling conflict and bottlenecks have also been identified by the 4D BIM technology, which helps to streamline the overall construction process.

Improving project visualisation

4D BIM technology helps to create the images for project planning, which helps to speed up the project scheduling and helps to ensure design consistency. 4D BIM technology also helps to coordinate the actions of the contractors and the team members, which helps to visualise the construction sequence over time, as well as helps to provide clarity on the project milestones and dependencies.

Learn about the working process of the 4D BIM modelling

The 4D BIM modelling process has been worked by integrating a 3D design model along with a detailed construction schedule. The steps involved in the creation of a 4D BIM model are:

Preparing 3D model

A structured and detailed 3D design model must be created for getting 4D simulation.

Developing a construction schedule

A detailed and comprehensive schedule has been created by using planning software, as the 4D simulation quality depends upon the accuracy of this schedule.

Linking model components

In the next step, 4D simulation software should be used to link the design components of the 3D models to the corresponding tasks in the construction schedule. This process helps to create an intelligent data connection that defines 4D BIM.

Generating and visualising a 4D simulation

After linking the model components, the 4D simulation has been created, which enables the project stakeholders to watch the project being built virtually over time.

Analysing, optimising and refining the plan

The project team member can review the sequence to identify the potential risks. Based on this analysis, the construction plan and schedule can be optimised and refined before the beginning of the project work, which saves time and prevent costy reworks.

Powerproject BIM

Powerproject BIM application helps to extend the design capabilities of the Powerproject software. This 4D BIM modelling software enables the project planners to link the tasks in their schedule directly to the 3D design model components. Thus, this 4D BIM modelling software helps to create an integrated 4D plan within a familiar project management environment.

Autodesk Navisworks Manage

The Autodesk Navisworks Manage software has been widely used for project review works, which excels at combining 3D design models from different disciplines. This 4D BIM modelling software enables the project team members to link model geometry to the construction schedules, which helps to create 4D simulations.

Fuzor

The Fuzor software has been known for its real-time rendering process, which helps to create immersive Virtual Reality (VR) experiences from the BIM design models. This 4D BIM modelling software helps to offer 4D simulation capabilities along with a strong focus on the high-quality visualisation process, which is very effective for the design presentations and reviews by the project stakeholders.

Trimble Vico Office

The Trimble Vico Office software helps to integrate 4D scheduling along with the 5D cost estimation process. The Trimble Vico Office software has the ability to create a unified workflow, in which the design scheduling changes can be reflected immediately in the budget of the project, thus helping to provide a holistic view of time and cost impacts on the project.
