The Augmented Technology used for Pokemon Go is driving the mobile game lovers crazy. Augmented reality, the technology behind the widely popular phone app Pokémon Go, can be used to highlight landmines or relay information from a drone flying above about enemies hiding behind a wall to soldiers on the battlefield.Read-More..

How AR related to BIM ?

Communication of design intent is enabled with Augmented Reality for Architects and designers which is a major challenge earlier.The strength of using augmented reality is delivering and understanding the vision of the project. Through Augmented reality BIM has taken virtual model to the reality.


Augmented reality is a live, copied view of a physical, real-world environment whose elements are augmented (or supplemented) by computer-generated sensory input. Virtual reality replaces the real world with a simulated one, whereas augmented reality takes the real world and adds to it with—in the case of architecture—a 3D model of your design.


With the help of advanced augmented-reality technology such as computer vision and object recognition, the information about the surrounding real world of the user becomes interactive and able to be digitally manipulated. In augmented reality, computer software must derive real-world coordinates, independent from the camera or from camera images.


Augmented reality is used in architecture and construction by placing a 3D model of a proposed design onto an existing space using mobile devices and 3D models. AR has been used in the video gaming and media entertainment for a much longer period of time to show a real image interacting with one created from computer graphics.


‘Pokemon Go’ is an entertainment augmented reality game. But BIM augmented reality will give you the professional look and feel of virtual world.

Why Indian Market

Though BIM software has been around since 1970s, how many AEC professionals in India use the software to its full potential?Read-More..

Indian Architects regard BIM as a tool that requires high level of understanding from the user to operate it. While CAD and SketchUp have been serving small to mid level firms meet their drawing and 3D needs, offices that handle large and complex designs are bound to switch to BIM due to clients’ demand. Leading builders are now appointing BIM consultants for better coordination between all disciplines.

 

I have worked in small to large firms. During a regular office meeting in a firm, a colleague requested for REVIT in office and my boss’s reply was

 

How can you write a poem when you don’t know the grammar?

 

What could be the possible reasons BIM has not caught on in India?

 

Cost

 

ArchiCAD and REVIT are the widely used BIM softwares in India. While Autodesk offers 3DS Max,AutoCAD and REVIT as a package,ARCHICAD also offers a suite of different applications in a single purchase. Cost does not seem like a constraint to switch from CAD to BIM.

 

Training

 

Yes, Training and experience in BIM application is a must. Companies which want to use BIM over CAD have to take the initiative to train its employees in REVIT from a result oriented approach. On-project training would be highly beneficial for the company on a long term basis.

 

Time

 

At the floor plan stage , BIM and CAD will take the same time to complete, but rest of the drawings, i.e. elevations, sections and 3D view will take lesser time to generate. The layer of information that can be added and extracted from BIM is immense. Many free plugins are also available for calculating material quantities and estimates.

 

Bentley’s AECOsim has several features packed into a single software. BIM definitely is not time consuming but yes we have to be patient when it comes to producing details. Indian Architects expect BIM to do all the work. Blown up details have to be drafted partly with 2D line-work and partly with detail components , hence drafting time required is the same, but modeling and documentation in BIM definitely reduces the coordination time.

 

Customization

 

General feedback from Architects who attempted to switch to BIM is that while some of the tools have been created to meet International standards, they need to be customized to Indian design standards. For example, the families available in BIM library are suitable for UK or American designers. While American manufacturers of Architectural products are providing BIM families free of cost, Indian product families are not readily available.

 

Design Process

 

The sequence of an Architectural project, if followed in the concept-schematic-design development-construction drawing-as built stages, using BIM, can produce exceptionally good results. Design changes would be reflected uniformly in all drawings when the model is changed . In the Indian context, the design approach is different from an International approach, so BIM has limitations.

 

Is it time for Architectural Institutions to include BIM in the curriculum?

 

It would be a good idea to introduce BIM in the curriculum at an undergraduate level to familiarize students with its advantages. Established designers are of the opinion that design schools are training their students in software rather than in analysis and creative thinking. While that is true to a certain extent, it is equally important to keep up with the technological innovations in every field. We as Architects have come a long way from the days of hand drafting to 2D CAD, 3D CAD and now we are at BIM. In my opinion, introducing BIM as an elective in the pre-final year in college gives a choice to interested students to get trained in BIM and work on a project from design to construction drawing stage.

 

BIM’s capability to combine model, drawings, details, material quantities, cost and time in one file saves AEC professionals a lot of time, money and trouble. Indian AEC professionals have to be ready to embrace new technologies that will improve their business and at the same time improve the quality of output.

Pooja resumed office after her maternity leave and what she had in store for her was a ‘Point cloud to BIM’ project.The process of converting 3D Laser scans of buildings to a BIM model is termed as ‘Point cloud to BIM’.Her company got their first ‘Point Cloud to BIM’ project from a long standing client who recently switched to laser scanning from manual survey.Read-More..


The client had sent 300 odd images of a famous museum in USA which they had to restore. They wanted the BIM model in one weeks time.She had a team and a deadline but had no idea how to go about the task.


All the ‘BIM’ and ‘Point cloud’ experts who gave a demo in the office were themselves uninformed and were of no help. It seemed like one week would be required to research and learn how to do the project and another one week to complete the task. The company could not turn down the client.


This project was the stepping stone to the next level of BIM model and in completing the project, they could become part of a prestigious restoration project of international importance.


There was limited information available on the internet. Pooja had to take up the project and complete it. She lost her sleep over it. She was torn between her wailing 5 month old baby on one side and her nightmarish project on the other. Being a long serving employee who has also earned the reputation of being the most reliable and efficient,Pooja could not give up. She was determined to complete the task.


These were the many questions that were on the teams mind.


What is point cloud?


In Architecture, point cloud is the raw scan of a building exterior or interior created by 3D scanners. The scan would be a set of points on X,Y and Z axis.


What is RCS and RCP file?


Point cloud data file cannot be directly used in a 2D or 3D application.


Autodesk ReCap converts raw scan data to scan files (RCS files), and project files (RCP files) that reference multiple RCS files. Both these formats can be attached to an AutoCAD drawing or REVIT application.


What is the best point cloud to BIM software?


The process for creating a point cloud to BIM model is 3D SCAN?PROJECT FILES?AS BUILT BIM MODEL. There are many point cloud to BIM applications like REVIT, Trimble VDC Services to name a few.


REVIT application was already in use, so there was no searching needed for a new BIM application to model. But once the painstaking process of modeling in REVIT started, by measuring point to point distance on the point cloud file, some areas were not clearly captured by the scanner.


It started taking a toll on the health of the REVIT modelers. Some complained of watery eyes and headache. By the end of each working day, they were fatigued and unhappy with the results.


Meanwhile, the client was getting impatient. He had to commence work at his end with the finished as-built-model.


Then Pooja chanced upon the application called Scan to BIM™. This application automatically recognizes and places Architectural and MEP elements which eliminates the laborious task of measuring and modeling each and every element. Trial version of Scan to BIM helped Pooja and her team to model the as built museum model faster. They completed the project with minor errors which were fixed eventually. They missed the deadline by few days but the client accepted the work and was happy with the outcome.


Pooja and her team accomplished what they thought was impossible and that evening they went back home with a smile on their face and a sense of fulfillment.
