London — Integrated design and operations consultancy for the built environment, Bryden Wood and BIM technology innovator, 3D Repo have launched a new platform for visualizing how construction projects change over time. Using Virtual Reality technology and 3D Repo’s database-driven Digital Construction Platform, the new 4D sequence visualization tool gives users a new perspective on design and construction projects. Accessed using market leading headsets such as Oculus and HTC Vive, the outputs will improve collaboration between project stakeholders, facilitate decision making and allow for better communication at all stages of a project.

A 4D schedule is a 3D model that includes the construction sequencing. This enables teams to analyze events on a time-line and visualize the duration it takes to complete tasks within the construction process.

“Once a design or construction project is underway, time is one of the most important factors to be considered,” commented Phil Langley Director of Digital Delivery, Bryden Wood. “As the saying goes ‘time is money’ and, by providing an accessible, easy to use 4D VR solution, we can help save valuable time when it comes to sharing information for decision making.”

Jozef Dobos, CEO, 3D Repo said, “By partnering with Bryden Wood to develop the 4D VR experience we have played to the strengths of both parties. Bryden Wood understand the different stages of design and construction projects, and how they develop over time, while we are experienced in utilizing the latest innovations, such as VR, to improve data sharing.”

The 3D Repo Bryden Wood 4D solution builds on 3D Repo’s cloud-based BIM platform that allows users to access, via the web, the latest 3D models and make real time changes and informed decisions. Often described as an online knowledge base the 3D Repo platform is different from other collaboration tools as it uses an element level database meaning that information is live, useful and accessible throughout the project life cycle.

The use of sequencing within original authoring tools allows timeline of models to be created which can then be played back in VR. Multiple sequences can be applied to each model allowing different scenarios and outcomes to be visualized. 3D Repo is also working on a number of revisions to the new 4D sequence visualization solution including direct web access, negating the need for VR, and integration with other planning / 4D software.
