Revolutionizing Railway Signaling through BIM

A precise design is required to run a highly secure and dependable signaling system like ETCS with Automatic Train Operation (ATO). All assets must be installed with a very minimal installation tolerance.


Traditional way


There are well-defined methods for installation activities along the rail track, which are based on rules and norms. Many of these jobs are traditionally paper-based — such as filling out spreadsheets and forms — necessitating a second activity of moving the input data into another system.


When installing and maintaining the track, the installation and maintenance crews rely on having the proper information on hand. To guarantee that all essential data required for optimal execution is obtained, storing data in many systems necessitates a high degree of organization. Collecting all pertinent information takes longer when information is stored in several systems.


The enormous distances between the office and the work location, as well as operating in places without a “net connection,” make information transfer complicated and sluggish. The traditional way to reporting is to work on-site for a week and then begin official reporting the following week when everyone is back in the office.


As a result, the findings — and perhaps the notification that some assets could not be installed due to collisions — are available a few days later in the design office. After that, the design, engineering, and installation cycle begin again.


A new dawn with BIM


Thus, to address the lacunae with the existing way of working it is important to use technology. The two prominent technology used in this case was laser scanning and 3D visualization services. First, the 3D model of the railway track would be created using BIM while integrating the geological data from satellite coordinates. The 3D visualization services offered by a leading BIM provider with the help of BIM can help to visualize the accuracy of the model and its placement on site. 




With the 3D model of the tracks offered through 3D visualization services, it is possible to ensure that the model is per the client’s requirements and is adhering to the required safety protocols. 


Point cloud services will help to monitor ongoing construction and ensure adherence of the construction with the model. In this respect, the point cloud services provider uses a laser scanner to create a point cloud image of the construction. The same point cloud image is converted into a 3D model through BIM software. 


By comparing the 3D model generated through point cloud with the original model created through BIM, it is possible to verify construction progress and track the accuracy of the construction. Thus, BIM has the potential to revolutionize the construction and installation of railway signaling mechanisms. 


However, the application of BIM does not end here. As a revolutionary technology, the application of BIM can offer several benefits to the construction industry as a whole. From reducing coordination issues to ensuring fast construction; BIM offers a plethora of benefits. It can also help monitor the entire construction activity and ensure that there are no bottlenecks. It can also offer accurate material and cost estimation for the project.

Using BIM Services to Shape the Future of School Infrastructure

Image
The importance of a school building in shaping the future of people cannot be overlooked. Not only do these buildings function as a center for education but can also offer social support services to the surrounding communities. In addition to offering flexible spaces, the school designs need to incorporate sustainability and safety. Pressed by these demands, firms are turning their focus to BIM engineering services to not only design and construct at lower costs but also offer designs that are safer and perform better.  BIM Services can be used to replace old buildings as well as help in constructing new and efficient school buildings. BIM allows for comprehensive construction cost estimation and the reduction of construction mistakes. The system is based on an intelligent model that is shared among many stakeholders and serves as a collaborative tool throughout the asset's lifespan. BIM engineering services are being used by governments and private entities all over the globe t

Factors that make Rebar detailing services a key component of the construction process

Image
A basic block or steel bar, Rebar finds application in reinforced masonry and concrete structures. Made from carbon steel, the rebar finds its use as a reinforcement or reinforcing steel. Rebar detailing services is all about creating shop drawings and fabrications drawing of the steel reinforcement for the construction process. The architects and engineers make design drawings based on the parameters like diameter, length of bars, and diameters provided by Rebar detailing service . This helps in avoiding wastage and delays and speeds up the entire construction process.  Methodology of Rebar Detailing Based on design drawing requirements, each rebar is detailed while representing a certain length, diameter, and shape. The placement of rebar is then shown in detail indicating the exact location, concrete cover, and the special way of placing the same if required. The bar bending schedule along with rebar detailing depicts the notation, weight, diameter, length, etc. of each bar. It als

Leveraging BIM Engineering Services to Enhance Interior Designs

Image
Building information modeling (BIM)  has a transformative impact on many disciplines related to the creation of a built environment. The application of BIM engineering services has the potential to transform the discipline of interior designing as well. BIM can offer a host of unique benefits to the design process of interior design. most importantly the application of BIM engineering services helps to create design models with enhanced convenience and speed-  offering designers the ability to visualize their imagination in a three-dimensional environment in the design phase itself.  BIM software can help by creating a 3D model of the existing interior or exterior structures of a building on which the interior designer can base his or her subsequent works. Another important benefit of BIM Engineering services is that it helps in coordinating and maintaining the consistency of the 3D model throughout the design phase. Irrespective of the scale or number of changes being made by the i
