Scan to Revit: 3D Model of Warehouse and Historical Buildings
This was a really exciting project: the 3D modelling of a large complex warehouse, two historic buildings and a couple of smaller warehouse buildings.
The project also included a topographical survey of quite an extensive area.
Scan to BIM: Falkirk Library
A total of 3 full days 3D laser scanning using a Trimble Tx8 and over 200 individual laser scans; the Aura team were sure to capture every aspect of the Falkirk Library so that the building could be modelled in Revit.
The scan data was used to meticulously model the internal space, including decorative features and staircases. Our client was delighted with the level of detail and accuracy of the final submission.
Topographical Aerial Survey : Edinburgh 3D Modelling
This point cloud model represents nearly 100 million data points recorded from the air.
Each full-colour data point is recorded to an accuracy tolerance of less than 30 millimetres which is almost topographical survey grade accuracy.
Here's the proof: our detailed topographical survey overlaid upon our point cloud model. You can't see clearly from this image but trust us, common features coincide perfectly.
Because we're just scratching the surface of the power of point cloud modelling, Aura is quite rapidly moving away from traditional topographical survey and working toward a work flow that automates most traditional survey activities. Our aim is to optimise turn-around while giving our clients far richer, more powerful data sets than they will have experienced before.
The level of detail that can be obtained from the air is outstanding and accuracy tolerances are becoming more refined with every survey that we deliver. The above isn't a photograph, it's a still from the less than 30mm accurate 3D model. Our models are used for planning, community engagement, 3D printing, design, contextual analysis, view point analysis and just about any CAD related workflow that can be imagined.
Above is another still from the point cloud, this time taken directly from AutoCAD. Many of our clients - architects and engineers - are astounded by the possibilities made available by modelling directly from point cloud information.
Aerial Point Cloud Model and NDVI Analysis : Aerial Survey Edinburgh
This site near the centre of Edinburgh equates to a 47 acre collection of buildings nestled amongst mature trees. For the survey, our land team installed a tight network of ground control points and our team in the air over-flew from Blackford Hill.
A photo-realistic point cloud model of the topography of the site (including the train line and all major roads beyond the site perimeter) was produced by photogrammetry and passed to the architectural team for master planning.
Because the site is steeped in history, the survey also included Normalised Difference Vegetation Index (NDVI) deliverables: from an infrared camera, subtle differences in vegetation density can be used to detect ancient structures below ground level.
A Full Suite of CAD Plans from Point Cloud Data : Perth Laser Scan
The brief: delivery of a full suite of CAD plans which included four complex elevations, three irregular floors, and a large topographical survey.
As always, the Aura team unleashed the most innovative technology: two types of laser scanner, a total station, and a GNSS unit. This combination enabled us to capture the the house and grounds in staggering detail. What's more, combining these technologies enabled us to complete the full survey in a day - the team leaving with so much data that they would never need to return to site.
Once the point cloud data was registered in Trimble Realworks, it was exported in .RCP format for use in Autodesk Revit.
In Revit, the complete structure was modelled, beginning with the elevations as captured above and working inward to model the interior.
While our client has requested the delivery of a suite of 2D CAD plans, taking time to produce a complete Revit model meant that we could easily extract the elevations and plans.
3D Laser Scan : Steelwork at Dunbar ERF
Using both Trimble TX8 and TX5 laser scanners, our team were charged with the task of surveying the entire steel structure for the Dunbar Energy Recovery Facility. Our client needed to know the verticality and level of each steel member. This was made easy by scanning the structure.
Aerial Drone Survey : Quarry Near Glasgow
Complete topographical survey delivered to our client as a point cloud model. Control established utilising Trimble RTK technology.
Aerial Topographical Survey : 800 Hectare Site
This image represents a photorealistic 3D point cloud model (generated by photogrammetry) of an 800 hectare site. Our team installed a tight network of ground control points to bring the accuracy of the model delivered by the air team to within 30mm. Overall flight time was approximately 4 hours. To have surveyed the same site from the ground would have taken weeks!
The model was used by our client in LSS to run various analyses relevant to the redevelopment of the old quarry site.
3D Laser Scan : North Berwick
This was a great little project that represents our smallest 3D Laser scan project to date.
Around the Rocketeer Restaurant in North Berwick is a low stone wall. Our client, IPIG, have been appointed to design and install a structural glass canopy round the building. To do so, IPIG have to know the exact profile of the wall... Cue the Trimble TX8.
From the scan date we produced a 3D model of the building and an extremely detailed mesh model of the wall profile. From these entities, we struck elevations, floor plans and sections for delivery as 2D CAD models in line with our clients requirements.
It may be a tiny elevation but it's an extremely precise one. Importantly, the profile of the top of the wall reflects the true profile to millimetre accuracy - something that would be extremely challenging to achieve without 3D scanning.
3D Laser Scan : Aura Office
Because we enjoy what we do, we obviously had to laser scan our HQ. From the point cloud model we then started to design our space.
The work-flow between Tribmle Real Works and Trimble Sketchup is incredible. In no time we had walls, windows, skirting-boards, and sockets in the model. All we had to do from there was start designing.
While some might view Sketchup as a "basic" tool for architectural design, there's a very real reason that Trimble paid millions to Google to acquire it: from an As-Built modelling perspective, it's intuitive, precise and, really quite powerful. Plus, we got to dip in to the model library to figure out what we are going to do with our furniture.
