This article is dedicated to the unnoticed sides of BIM. The world is rapidly adopting BIM and improving the AEC industries’ outcomes. From the designing phase to the erection of the structures, from 2D CAD to realistic visualization of the buildings, from manual billing to automatic quantity take-offs and even more, BIM is benefiting us with them all.
Though there are some countries which are unaware about BIM and some AEC professionals are not ready to accept it. The reasons can be many. Some professionals fear of losing their jobs with the introduction of this new technology and some hesitate to learn the new skills. As a result, the user at the end doesn’t get a chance to taste the advancements of BIM.
No doubt there are some developed countries which are highly dedicating their human resources to BIM and have even successfully implemented Level-2 BIM. India is known as a BIM factory but still struggles to use much of the BIM benefits.
These days there are plenty of BIM software to choose from. One of the popular BIM software is Autodesk Revit. After an introduction to Revit back in 2014, I was reintroduced to it in a totally different way in March-2016 by Dr. H.S. Rai. Sir gave me some new ideas for utilizing Revit as a structural engineer’s tool. The idea was “Automation in Design”.
For the above work, I taught myself online with another amazing software named Autodesk Robot Structural Analysis. As the name describes, it is the software for structural designing and analysis. The purpose was of direct integration of the two software.
Then, I modeled a simple RC structure in Revit and then analyzed in Robot. After that updated the model in Revit and got the 3D visualization of the reinforcement of the whole structure. Then using a 3rd party Revit plugin named Smart Assemblies from AGACAD, I got fully automated rebar drawings of the desired component with automated dimensioning & annotations too.
Thus, saving a lot of time from manually drafting the structural drawings in traditional CAD software.
This is a very uncommon type of practice. Though Autodesk provides such integration in both Revit and Robot, but professionals are mostly unaware of it and not readily using it.

While researching on BIM (Building Information Modeling) here at TCC in GNDEC, Ludhiana, I’ve been going through many interesting topics. One of the fascinating topics is of AR (Augmented Reality). Whereas, a recent augmented reality game Pokemon Go has driven the world crazy by a storm.
What if such concepts are applied to BIM, Engineering and other fields?
There comes a mobile app named Augment. I tried that and it was a wonderful experience. The user interference is simple. The app reads OBJ file.
The app comes with plugins of various designing software like Revit, 3DS Max, Sketchup, etc. I’m a Revit user so I downloaded its plugin and exported the OBJ format of my Revit file then uploaded that file to the augment server.
Right now, such technologies are in developing stage and a lot more can be done. The near future is VR (Virtual Reality). Who knows one day we won’t require CAD drawings on the construction field.
This is a G+3 building modeled using BIM approach. Though there can be many approaches as per the convenience and the accuracy desired.
The basic concept of modeling using BIM approach is to model a building in such a way as such it is constructed at the site. This adds to the FM (Facility Management) of the building throughout its lifecycle. One can access every floor and every component of the building as per the needs.This is one of the basic fundamentals of BIM which many profess
This is one of the basic fundamentals of BIM which many professionals skip to implement.
BIMserver.org is a FOSS ( Free Open Source Software) which is something very interesting & useful for AEC industry in the field of BIM. Professionals can work on it from their different locations and have a good integration among themselves regarding the project. It can be deployed on a dedicated server or a local host.
Professionals from AEC industry can upload their respective model of the project on a single platform and update it with the revisions being made. The users can then add their respective models to the project as subprojects.
Then their respective models are automatically merged by the server and the final project file can be viewed and downloaded.
There are many other functions that are available in BIMserver. One of the important function is Query. It is a type of language originally made for BIM to call BIM objects such as footing, column, beam, slab, roof, stair, window, door, rebar, etc.
It has many other functionalities similar to Solibri Model Checker, like clash detection, code checking, etc.
While I was on the way back to my college, two of the fellow travelers who were sitting just with me dropped off to their bus stop.
Both of them started the journey along with me from the same place. Talking to each other they introduced me themselves & I learned that they are CCTV service providers. They told me that they left the studies after passing off 12th standard and then just went into this field of CCTVs. Now, they are earning quite well then a graduate engineer.
Then, I started questioning about the way in which they provide their services to the clients. They started telling about their various problems while executing their services. Now here started the BIM discussion.
They told that they go through the CAD drawings of the building to mark the points for their CCTV locations. This makes them frustrated as most of the time such 2D drawings are hard to understand & visualize by them as well as the clients which make their communication vulnerable. Secondly, many times drawings are not even available.
Then I introduced them about BIM – Building Information Modeling, its basic concept, various benefits & how can they implement it.
At first, they were astonished by the idea. They said it would make their work much easier & efficient than before. They would be able to visualize the building virtually and execute their services through it. Also, this would be used by them for the entire life cycle of the building.
Further, there were many other brief conversations related to the system. They also agreed with the mafia created by Architectures fetching big bucks from the clueless clients.
Overall, that one-hour interesting travel went so fast with time. What I can conclude is that we really need a BIM awareness and to diffuse BIM here in India we need a collaborative effort.
