Walk to Work.

I walk to work every day from the train station to the office. I thought I'd  share my journey, with the entire route which has been captured by point cloud and all the in ground services modelled.
The 1.5 km Journey does not take me 2:30 minutes

The point cloud data equated to 3 GB per 100 meters. The point cloud data was processed with Recap Pro and service modelled in Autodesk Civil 3d. Both data sets were overlaid in Autodesk Navisworks and the viewport transition to create the animation.
So how did I manage to Create a render animation with 3 GB x 15 = 45GB.
The workflow to create an animation with s large point cloud data set

1. Create and save the first viewport. The viewport needs to have the correct target eye level.
2. Apply a section box to the view, while keeping in mind the view depth to be limited. The intent of the section is to limit the amount of point per view when rendering the animation.
3. Update the viewport. Edit the viewport setting.
4. Pan forwards 100m or so to the desired location. Save the viewport and drag the section boxes.
5. Keep creating and staging the viewports, until the final desired location.
6. Now to stitch all the views together, create animation folder and drag in your views.
7. Click play and watch your animation.

Stadium Station

Its been a long time since I've posted any thing new on my blog. I've been locked away working on a great project, which I would like to share with you.

This Video is just a small clip of the over view of the Project. 

Infrastructure BIM model

I've finished up working at DoT and haven't really had time to blog / document about the work flows from the project. The project was a business case for a tack slab through the heart of a CDB. My involvement was looking at the cost impact of existing services and infrastructure. This was done by traditional feature survey and laser scanning of the 22km (500gb of point cloud data) alignment to create a BIM model of existing services, using AS5488 (SUE) classification of subsurface utility information as a base line. Majority of the existing in-ground services where modelled to class C with a couple of major services to class B. The model consisted not only of the existing infrastructure but the proposed light rail infrastructure which was created with multiple software's. 

The simple definition of the BIM process to create the model would be similar to a carpenters set of tools, with each piece of software having its own key use. Similar to how a carpenter uses specific tools to construct a house. 

The exchange process between different platforms was done via landxml. 
A simple list of the software's used and their function. 

• Bentley Rail used for the rail design
• 12d used for the road design
• Civil 3d for the existing surface and existing utilities 

The large data set of the point cloud was processed using Recap which reduced the file size of the point cloud data from about 500gb down to 150gb. Which had the point cloud data set usable on a 22km alignment. 

All of the above was placed into navisworks to run multiple rules to determine the impact of the light rail on the existing infrastructure with the results exported to excel to be processed and costed. 

This Video below and what has been described above is only a snippet of what was done. On the bottom of the screen each service is colour coded.

Some of workflows I've blogged about already and have many more work flows to come.
