Existing site conditions - steel work

Scanning has once again proved a great tool to assist general survey works.

Coloured point cloud

 In the space of a couple of hours the scanner rapidly captured existing steel work on site. Numerous dimensions between these structures and relative to grid lines were required to ensure prefabricated components will fit when they arrive on site. Scanning has provided invaluable for this project as the single site visit has allowed for multiple requests from the client to be responded to without additional site visits.

Heritage and Design

A couple of heritage projects have come across the desk recently which create something new and trees have been the new focus which makes a nice change. Scanning has once again been used to generate 3D building models to allow for restoration and redesign of heritage buildings.

More interestingly scanning has also been used capture trees to allow for detailed project design One project incorporated heritage trees where the design concept was to closely interact with the tree making it a park feature. Scanning allowed the full complexity of the tree to be accurately and efficiently captured to allow the design to interact with the tree and still ensure preservation. The raw point cloud could then be rendered against the design also allow for detailed visual analysis and community consultation.

For the next project, a proposed subdivision required building envelopes to be designed to account for the existing trees on site and allow suitable clearances should the tree fall. Scanning allowed for the trees to be rapidly located and then plotted and a suitable clearance determined.

2011 Already

Christmas has somehow been and gone and so has a unique project for RPS. In the build up to Christmas RPS scanned the entire Queen Street Mall in Brisbane over 3 nights completing 58 scans. The point cloud dataset was then used to construct a 3 dimensional solid model of the mall including all features, fixtures and light fittings for the purpose of a lighting study. The deliverables along with the 3D CAD Model were an  internet explorer based viewer of the point cloud dataset allowing all consultants a google street view type environment for site familiarisation and "orthophotos" generated from the pointcloud.
