Visualization and 4D

Visualizations are computer-generated images of objects and environments.
With a visualization you can achieve exactly the style and expression you want. Colors and materials can be changed as needed, so that you get the right images to promote understanding of the objects and their environment.

There are primarily four types of visualizations: Context images, 3D scenes, Production images and cross-section views. The different types can help highlight the desired information.

In addition to the 4 types of visualizations, there are different project types. In Banedanmark, we primarily use images, video and 4D time planning:

Images

There is no better way to show the exterior of a building than using photorealistic digital images. Images can help focus on surfaces, texture and lighting, as well as help communicate the project. It gives the opportunity to show how the construction could look in real life, as well as to facilitate communication between the construction partners. Images provide the ability to communicate the purpose of any design to fit any project.

Video

Video is also a great way to take a virtual tour, which is more expressive as you can use sound to contribute to the images shown. Videos can cover every angle and detail of a project, giving the opportunity to connect to any area by making them experience the depth of the space.

4D-planning

A 4D model (3D model with a time dimension) is used to plan the execution period of a project. 4D-planning can be used with different focuses such as simulation of deliveries, space utilization of the construction site, machine usage, construction rates, etc. 4D-planning is a powerful tool for visualization and communication as it can give those involved a better understanding of project milestones, ongoing updates and require a position to be taken for complex nodes or simulation scenarios, in order to be able to control the optimal execution at all times and document the changes that take place along the way.

Visualizations can contribute to:

  • Enables a better interdisciplinary understanding of pace and sequence in schedules, including display of slack and critical path.
  • Visible and enables analysis of treated and untreated risks.
  • Enables dynamic changes and visualizations of schedules in a unified data set.
  • Integrates the planning of manpower, material, location and material resources in a unified view.
  • Spatial and planning conflicts can be visualized and eliminated.
  • Enables viewing of rough volumes/indications of future conditions.
  • Enables checks on quantities and actual production during execution.
  • Optimizes time and location restrictions in schedules relative to each other.
  • Enables an overview for the client of the actual production against the planned production in the execution.
  • Enables early maintenance analyzes in the execution planning of the finished project.
  • Enables more accurate offers for contract work as the contractor can see the complexity and various dependencies in a number of activities in 3D.
  • Optimizes construction site management.
  • Can be used for public hearings, public communication and the like.
  • Enables regular updates around actual production for builder in the same units as in the bid list.
  • Enables monitoring of purchases, deliveries and general supply to work and construction sites.
  • Enables rapid analysis on the redeployment of temporary constructions and workplace measures.
  • Enables accurate risks and their solutions in relation to work environment coordination and safety.
  • Minimizes interdisciplinary planning time on projects.

In order to achieve the best visualization, the following resource prerequisites should be considered:

  • Modeling and quality assurance software
  • Common Data Environments (CDE)
  • 3D subject models
  • Design standards and norms
  • Necessary/adequate hardware
  • Software
