As well as generating 3D models of bespoke, custom-designed temporary works support structures and scaffolds in the estimating stage, Duratec uses them for the duration of the project, keeping clients up-to-date on a daily basis with the works’ progress and ensuring project team members are on the same page.
Duratec has been remediating concrete-and-steel structures since 2010. During that time, the company has honed its expertise in the design and construction of fit-for-purpose scaffolds that provide both safe and easy access to assets.
3D modelling from the get-go
The company’s in-house 3D reality modelling capabilities allow clients to visualise the scaffolding required for their project during the tendering stage, before a contract has been signed. Duratec can generate both 3D models and fly-through animations, giving the client a clear idea of how the scaffold will function throughout the works.
Unlike many companies, Duratec continues to use 3D modelling for the duration of the project, allowing clients to track its progress. As works are completed and scaffolding is moved, altered or added to, the 3D model is updated and sent to the client as part of a daily report. It serves as tangible evidence of the works’ progress and facilitates transparency and clarity at all stages of the project.
How it works
Assessing the structure and capturing data
The process begins by assessing the asset for which Duratec has been engaged to undertake remediation works. The assessment involves capturing data, either visually or digitally, using drones, bespoke camera rigs or precision surveying, to name just a few methods. Drawings provided by the client can also assist in this process.
Creating the model and putting it to work
Using the captured data, Duratec’s in-house designers digitally construct a high-resolution photorealistic 3D model of the asset. Essentially, this online representation provides the experience of a site visit at survey-grade accuracy.
As the works kick off, the team uses the model to illustrate the construction of the scaffold. From thereon in, the model is used to indicate how the scaffold will be adapted to facilitate the progress of the works.
Colour-coding signifies which components are to be assembled or removed, which beams are to be replaced and which compensation plates are to be welded on. As the works progress, the project manager can easily see what needs to be done next and this assists with scheduling, reporting and labour rostering.
The model also clearly indicates how much work remains and is of great assistance in the event of scope growth. Should the crew undertaking the works discover that repairs beyond the original scope are required, the 3D model allows the team to easily communicate this to the client. Duratec can use the model to illustrate the issue and propose a solution. As a result, the client is better informed about the necessity of a variation to the original scope.
3D modelling tools of the trade
Duratec’s design team uses the following programs:
For 3D modelling
- SketchUp
- Revit
- Advance Steel
- SolidWorks
For animation
- Twinmotion
- Adobe Premiere Pro
The team is also working on implementing a virtual reality headset, allowing users to virtually tour (walk around) the 3D models using Twinmotion.
