Alternative assessment 3D scanning and new applications for measuring open a large number of possibilities for all kinds of buildings, even those more complex.
The detailed and reliable data measurement is especially needed in the planning phase of buildings, renovations, interior and exterior installations. Not surprisingly, the accuracy and the perfect shot of these parameters are the basis of any solid measurement of property, in the field of architecture and processing of simple 2D representations no longer enough. Hence the scan in three dimensions has become one of the most useful tools to carry out this phase in all types of buildings, even those that have a higher degree of complexity.
As an example of the possibilities offered by this new way of working, we will raise a case in which the Laser Scanner Auto Focus, marketed by Faro is used to check how you can expand the profitability of projects and avoid planning failures.
To introduce the project, the architectural Laser Scannning Architecture was commissioned to contrast the existing plans of an office building that was sanitized with the real situation. The measurement of this administrative center was performed with this tool by 30 laser scans in just 5 hours, which were documented in 3D a total of 2,800 m2 of façade and 1,500 m2 plant building.
AVOID COSTS
Today, architectural studies continue working mostly in 2D mode, which requires a representation without deformation as the basis for all levels of interior and exterior. Meanwhile, this latest version allows all 2D presentations that are needed, as well as floor plans, sections or views, which can then be imported to scale CAD software design.
This comfortably contrast the state of planning with the current building. Thus, possible errors are detected early and can be amended before starting the construction phase, avoiding the high liability risks that may be required later, while achieved respond to increasing demands for accuracy and profitability.
In the specific example of the office building mentioned above, considerable differences with the laser scanning method are. Compared to the CAD planning, you can clearly recognize differences in the area of the central beams and right outer wall.
If these differences between the plans and the actual situation are not recognized until mediated and work, the consequences can be increased additional costs and significant shortcomings in the design itself.
On the contrary, with the help of scanner is achieved in the previous phase safety of effective planning of this property. In fact, differences between the actual state and plans of this administrative building at all plants were approximately 30 m2. This measurement accuracy allows timely detect and report possible loss of leased surface.
Furthermore, the facade can also be used measurement results of this tool. With these data superimposed on the manual scanning planes of the facade, visually controlled axes grids, lintels heights and details at an early planning stage. A valuable help to avoid further errors and ensure smooth execution of the work.
However, in the example we are dealing with in this article, after the assessment and direct comparison with individual manual measurements performed on specimen’s points, it concluded the necessary precision of about 5 millimeters’ window opening had prevented reliably with respect manual measurement.
In this case, differences were detected with a dispersion of 0 to 15 mm. However, with a tachymeter measurement additional had been able to optimize the result, although it is true that the cost of time would have been high.
Yes, it was found that the steel beams of the roof structure were not focused on solid supports the habitable zone. With this information, the lining of the beams on the top floor can be “eccentric” to achieve the desired uniform for the facade.
MULTIFUNCTIONALITY
For all the above, the comparative advantage of 3D scanning over other methods of measurement lies in the comprehensive documentation of the work and the multifunctional of the analyzed data.
With scans axonometric views or perceptual independent positions are generated. Video animations allow develop views that can always be changed. Thus, the content of 3D scans becomes a database for a wide range of innovative viewing options.
Furthermore, in the field of preservation of evidence, these three – dimensional images serve to demonstrate and represent the uniformity of the components.
In the image shown on this page, the areas represented in red are 2.5 cm anterior to the reference level, while areas represented in blue are 2.5 cm behind. Therefore, after many years you can still document the condition of the property accurately and safely.
With the Scene software generated 360-degree panoramic photo quality that allow visual and geometric analysis of the building. The data density is so high that facilitates even generate planes remotely.
This makes it no longer necessary to go to building more often for new measurements, which saves time and costs. For the competition, the participating companies can view high – resolution panoramic Internet and bid calculated accurately, which also reduces the total cost of the work. These panoramas can be included on the website of the architects or contractors
