New technologies pave their way, leaving behind other models used previously but having remained obsolete as of today. Such is the case of the so-called CAD technology. CAD design (Computer-Aided Design) makes reference to the use of computer technology for design, with software that has been most employed by designers, architects and engineers for years, to generate 2D and 3D building models.

There is currently a more complete and efficient tool known as BIM, Building Information Modelling. The concept refers to the process of data generation and management during the life cycle of a building. Such data management is possible thanks to a new software program which main characteristic is that it allows three-dimension building modelling and in real time, reducing response time in case any issue might arise, and minimising the use of necessary resources.

Main benefits of BIM, as opposed to CAD

  1. The main benefit or difference of BIM with regard to CAD is that in the case it was necessary to modify an element, only the model would have to be changed, being updated automatically in each and every display. On the contrary, with the CAD system, each and every drawing and display had to be modified manually, which is to say, the BIM system works in a parametric environment, which means that in case of changes in the model, drawings would not have to be modified.

 

  1. BIM technology makes data collection easier, by increasing dependability and productivity, while other inconvenience of the CAD system is that in case a mistake occurred when providing dimensions or other parameters, we would come with it all along the process, being more difficult and costly at the economic level to compensate it once the project is finished. Thanks to the BIM system, it is possible to generate a virtual system in the right way, having at disposal fully reliable information.

 

  1. As for BIM technology, information comes first. While CAD systems where specifically focused on design, BIM makes most use of the available information, paying special attention to each and every element that comprises the design of a building.

 

  1. BIM technology is sustainable. As it has been mentioned above, this system allows the considerable reduction of designing time, as well as response time in case of problems, which in turn results in significant resource saving, thus reducing the energy needed in all processes and minimising the emission of air pollutants into the atmosphere.

 

  1. Estimation and anticipation in case of error. It is possible that some problem may arise during the design and development stages. However, BIM systems are able to anticipate problems and mistakes, increasing security and saving additional costs and time.

Where can BIM technology be used?

Building modelling used in BIM technology includes all the design stages and life time cycles of the building, all of which is assembled under one single three-dimension model. This model includes the features of the materials employed (weight, resistance, information about the manufacturer, features, etc.), which allows the possession of reliable information at all times, as well as the reduction of costs of production.

  • The architectural field is one that makes most use of BIM technology. It becomes to all intents and purposes indispensable when designing buildings, distribution centres, door and window frames, finishing touches, volumetric display…

 

  • In regard to construction, building modelling gains particular relevance since it allows the programming of the different stages of the edification and the inclusion of updates at any moment, without posing any further problems.

 

  • Engineering. Within the field of engineering, there is a wide variety of information modelling software programs, aimed to design the infrastructure of air-conditioning systems or the air volume control panels, to define the entire wiring structure and power control panels, or to establish sewage, water or gas distribution systems.

 

  • Safety and security. Building modelling allows the inclusion of design in all the required security and safety systems, from emergency exit doors to fire-detection systems, fire-resistant doors, etc.

 

  • Interior and structure design. Thanks to this software program, the elements and materials that will shape the building can be visualised. This is of great importance when presenting to clients the final result of possible alterations or changes in the building.

BIM technology implies the digitalisation of design in order to have higher control over the building area and environment.

Manusa can provide all types of access solutions in BIM format in order to make easier the integration of all their products into the projects, as well as to ease the specifiers’ work and that of other agents involved in constructive processes.
