May 25, 2022

Make a laser scanner survey and integrate it with the BIM allows you to overcome traditional CAD design methods and create more defined models, also saving in terms of time and costs.

Let's see what they are Advantages of using BIM and Laser scanner in synergy and what are the Areas of application.

What are BIM and laser scanners

In the previous articles we have analyzed in detail the laser scanner and its advantagesThe laser scanner is a tool for carrying out surveys and create, through the point cloud obtained from the scan, a 2D or 3D digital model extremely realistic of complex objects and buildings.

The BIM, acronym for Building Information Modeling, is a working methodology that allows you to create a digital model of the building. The model contains a lot of information regarding all the stages of the building's life, from its design to its dismantling.

Used together BIM and Laser Scanners bring the process to life Scan to BIM, which allows you to use the point cloud obtained with the laser scanner for extract a BIM model in which to insert all the information and data that the scan has provided.

Why is it better to carry out the survey with the laser scanner?

Compared to traditional processes, it is possible to create laser scanner scans It is more advantageous for several reasons:

  • It's a more process fast, where you only need to visit the site once, reducing the need for travel;
  • It's more detailed and allows you to get much more data from scans;
  • There point cloud which is obtained from the scan can be easily modified, updated And optimized, to obtain only the information necessary for the project.

The advantages of Scan to BIM

The process Scan to BIM allows you to obtain a accurate and optimized three-dimensional digital model of the building, That:

  • Contains all the information for the realization of the project, relating to the position, to the materials used, according to the type of components used (windows, doors, etc.) and also to stages of the building's life, from its design to its dismantling;
  • AND navigable;
  • It can be easily Managed by work to be carried out.

THE advantages of Scan to BIM are many:

  • It allows you to acquire the real conditions of the building and to have a Overview of the project;
  • Reduces the margin of error in the different phases of the project life, in particular in modelling and design;
  • Guarantees greater quality of the project thanks to the remarkable amount of data that are obtained;
  • It decreases the timing and consequently the costs of the project;
  • Improve the team work, ensuring greater transparency And collaboration, in particular thanks to theuse of BIM and cloud to share information.

Areas of application of Scan to BIM

Let's see now what the Areas of application of the integrated use of BIM and Laser scanner:

  • Phase of design, to better understand site conditions and make the right decisions, reducing errors in advance;
  • Phase of construction, to track project changes and check more quickly and effectively that there are no discrepancies between the digital model and the building under construction;
  • Facility Management, with Scan to BIM the internal management of the building is simplified, for example in the case of renovations, emergencies and system management;
  • The scan to BIM it is finally fundamental in building restorations historians, in the expansion of pre-existing buildings and in the creation of Digital Twin of the building.

Why do we hear more and more about the integration between BIM and GIS?

May 25, 2022

The construction sector is becoming more and more advanced. This is thanks to new technologies and working methodologies such as BIM and GIS, which used in synergy can bring numerous advantages at every stage of the project.

Let's see what they are, the advantages of integration and the areas of application.

What is GIS?

We know the situation well by now BIM methodology, which allows you to create a digital model of the building full of information regarding all the stages of the building's life, and which together with the laser scanner survey gives life to the process Scan to BIM.

The GIS, or rather the Geographical Information System, in Italian Geographic Information System, collects the data not on the single building but on the territoryIt is a tool that performs analysis and representations of space and the events that occur within it, thus allowing for correct management and planning of the territory.

Both tools are based on the data and their integration has several purposes:

  • Provide a Geospatial context of the building (e.g. flood risk, infrastructure status, etc.) to make better decisions about the entire project at every stage of its life (from materials, to exposure, maintenance, etc.);
  • Have in one place the BIM and GIS data of the work, such as geometric model, technical data sheets, position, territorial plans, cadastral data, etc.  
  • Make a unique database even richer in information, easily accessible, secure and updatable, where GIS data enriches the BIM model and BIM enriches GIS information systems.

What are the advantages of integrating BIM and GIS?

It's clear how the synergic use of BIM and GIS brings numerous advantages, among which we can list:

  • Have a more realistic context for design of the works;
  • Less chance of error in the planning stage;
  • Reduction of timing and costs of project execution;
  • Greater involvement and collaboration between team members and greater interoperability;
  • Realization of more sustainable and local-friendly projects. GIS and BIM information can in fact be used to improve the optimization of environmental resources, energy saving, safety, etc.;
  • Possibility of Building smart cities using IoT and the ability to connect objects to each other thanks to the shared coordinate system.

Finally, one of the main advantages of integrating BIM and GIS is that although there are software to integrate the data, in reality there are numerous tools already in our possession to merge data and avoid the cost of new software.

Among these we find:

  • The use of the Open Street Map maps;
  • The use of the shapefile;
  • The import of land through the Digital Terrain Map.

The application sectors

There are numerous areas where the union of BIM and GIS can provide numerous advantages, both in the public and private sectors.

  • It can be used effectively in the design of a work, but also in architecture and in all fields where it is necessary to take into account the territorial component;
  • It is also necessary for the small or large scale infrastructures to obtain a complete cartographic system, for example of bridges, rest and service areas, etc.;
  • Finally, it is fundamental adoption for the Public Administration, which will be able to manage the territory more effectively and even create structures for the automated control of building practices.

One of the future applications of the integration of GIS and BIM could for example be the creation of a public works register, which could be linked to the National Information Archive of Public Works to monitor its status and evaluate the interventions to be carried out.

The advantages of carrying out surveys with the laser scanner

May 4, 2022

With the laser scanner it is possible to realize realistic 3D digital models and more precise than other methods, saving time and money in the realization of the project. Let's see how it works and what are the Advantages of laser scanner surveying.

What is a laser scanner and what is it used for?

The laser scanner is a technology that allows you to quickly create a highly realistic 2D or 3D digital model of complex objects and buildings.

The scanner works through a laser beam emitter connected to a PC and specific software. The rays hit the object in millions of points and come back with the data relating to the x, y and z coordinates of the building compared to the scanner.

The scan result is a point cloud, or a grouping of points obtained by the laser that contains a lot of information about the object, such as size, position, materials used, color, etc.

The higher the number of scanned points, the closer the scan will be to reality, for this reason To obtain a more detailed point cloud, multiple scans may be necessary, which will be automatically merged by the software into a single image.

This technology finds infinite applications in various sectors, including:

  • Design;
  • Engineering;
  • Facility management;
  • Protection of cultural heritage.

Advantages of Laser Scanner

Why choose to use the laser scanner? Compared to other technologies for topographic surveys, the laser scanner survey has several advantages advantages:

  • It's more fast, efficient and precise do-it-yourself surveys and photogrammetric surveys, particularly on vertical buildings, complex or difficult-to-access structures;
  • It guarantees a high level of detail in the acquired image thanks to thehigh amount of data that gets;
  • The detected points have a different color based on the scanned material;
  • Can be combined with working methodologies such as the BIM for creating 3D objects.

Even in the results obtained from scanning, the laser offers numerous advantages, in fact it allows:

  • Analyze the state of conservation and degradation of the materials;
  • Process all the Project Phases;
  • Simulate interventions and any changes to the project;
  • Create defined presentations and show clients the different phases of the project, from the progress of the works to the final stages of the work;
  • Manage the different phases more effectively, minimising errors and saving time and money.
