Since the late 1990’s, laser scanning-also known as 3d laser surveying-has gradually replaced traditional surveying methods in various endeavors, such as: architecture, where it helps to identify repair needs and assess security measures; construction, where it aids in erosion measurement and building and site modeling; engineering, where it aids in clash control for piping and BIM modeling; historical conservation, where it protects heritage objects by storing their original data; law enforcement, where it helps to gather crime and accident scene evidence; and telecommunications, where it aids in telephone line planning and patrolling. In each case, surveying lasers deliver to the entity that uses them at least four benefits compared to traditional survey methods.

In the past, the timetable of a project that required in  BIM Services depth data gathering was significantly expanded by the surveying process, which often took days to gather the information from a single shoot point. Today, however, laser scanners offer quick results that older technologies can’t, often finishing a project that involves several survey points in a single day. Because faster results means more time to earn money, the expedience of laser scanning is more than a convenience, it’s a factor that could increase your bottom line.

Because lasers scanners abbreviate the data gathering process, they also reduce its cost. In traditional surveying, the surveyor reemerges whenever a new survey data issue arises. But laser scanning produces one-time, computerized results that can be manipulated and repurposed as the client sees fit. Scanners also reduce survey cost by avoiding the costs of 2d and 3d drawings. While some scanning providers offer the drawings to clients that want them, their usual delivery is hard discs, which don’t require expensive supplies or the involvement of draftsmen.

With traditional survey data, what you see is what you get. Conversely, scanning results can be manipulated and repurposed in numerous ways. That’s because it can be expressed in three models that contain several sub models:
polygon mesh models, which are mostly un-editable and used for visualization purposes; surface models, which are editable at their surface and are used for modeling organic and artistic shapes; and solid CAD models, which are fully editable and are used for direct manufacturing. Some entities use all three models, while others don’t.

Built environment modeling is a subject that is popular in the industry today. But what does this term exactly mean? While there are various explanations you can find on the internet, we can say, in layman’s term, that it is an effective method to create a ‘virtual representation’ for any building project.

BIM allows you to develop a scaled virtual model (others call it “digital prototype”) of your building project using a powerful software, which provides not just a 2-dimensional model but 3d visualization as well. This is an effective way to simulate a project and understand its behavior even before the construction begins. In other words, this helps you to improve your building aesthetic features as well as its components’ functions as you can compare several models of different building design alternatives.

Speaking of building simulation, BIM does not only allow you to establish architectural data but other engineering disciplines as well such as MEP (mechanical, electrical, and plumbing) and structural data – all these can easily be simulated in advance and therefore can provide you better results.

Because the data is stored in the central place of a BIM model, you can easily make any changes and have them easily replicated to other components of the system such as in floor plan and sections. This just means that all these automatic synchronizations provide a stringent quality assurance of data, and an easier way for document presentation. Any changes made are easily coordinated across all the components of the virtual building model.

There are other important information that are not directly visible during the course of project development and these might cause a negative impact to the overall process when overlooked – e. g. miscalculation or misinterpretation of information can cause such impact. Information on schedules (the timeline of the project), cost estimates and budget projection, and the number of manpower are just the most appropriate examples of information that are prone to error. Through the help of BIM, you can easily organize such information, making it sure that all of the system components are well-managed.
