4D scheduling is suitable for building and infrastructure construction
4D technology can be implemented equally to building and infrastructure construction, and any 3D data model is suitable as a starting point for the scheduling. There is no upper limit for the data content, and it is possible to visualize building frame implementation schedules as well as, for example, electrical and HVAC works.
4D scheduling creates a visual overview of the construction site. It is therefore a building information model that can be used to present the step-by-step progress of a construction project towards the jointly set timetable, cost or responsibility objectives in an easily-understandable way.
A versatile management tool
4D visualization visualizes the aspects relevant to the construction project. Primarily, 4D scheduling serves the site management and shows how much time has been allocated for the various work phases and how construction is progressing. We can visualize the entire construction process, such as factory production and design phases. Based on the construction schedule, we can also make a data model-based planning schedule consistent with it.
We are also constantly developing new product applications together with our customers. 4D scheduling technology can be utilized, for example, in the cost and carbon footprint management. The achievement of different objectives can be monitored separately or in the same view.
An efficient tool for takt production
In the 4D schedule, it is possible to view the progress of the planning and implementation, side by side, or the difference between the construction schedule and the realization. We use different colours to illustrate what has already been achieved on the site and at what stage the construction should be.
4D scheduling involves enriching data models. We record the working time required for installation for each object of the model, which means that the model tells the workloads by work type at a certain work phase and location. 4D scheduling is therefore an excellent starting point for takt-based scheduling. Site-specific workloads can also be produced at the beginning of the project on the basis of the spatial model.
In addition, the planning needs schedule can be visualized with space and area-specific views, so that the designer knows immediately for which area the next implementable plans must be produced. In addition to visualization, the data can also be moved, and the need dates can be exported to the planning tools, so that the designer can filter out only those structures for which plans are needed next. A reliable overview supports takt production, and tasks flow steadily and predictably from one phase to another.
Schedule risk management during the various phases of the project
4D scheduling can be implemented during different phases of the project. The best result is achieved when schedules are created as 4D schedules right from the beginning. In this way, surprises can be avoided and scheduling and cost risks managed in a cost-effective way.
The project kicks off immediately after the architect has created the first spatial model. As the project progresses and the data becomes more accurate, spatial model-based data will be replaced by building component-level models in different design areas. Due to the process, the best available data can always be found from the same tool.
If the construction schedule has already been established, the feasibility of the project can be ensured with 4D scheduling. Visualization helps to detect errors in phasing, for example. 4D scheduling supports decision-making and improves the transparency of data and data-based management. The 4D schedule takes the precision level of the schedule to a whole new level: a building component-level schedule with a buildable order is generated already at the general schedule phase.
Safety planning in a 4D view
4D scheduling provides an easy-to-use tool for safety planning. We can link the hazards and safety risks of different installation phases to 4D visualization. In this case, for example, protective fence orders and construction site logistics are planned proactively. It is also possible to record incidents and near misses in the 4D schedule for monitoring and reporting purposes.
