Building Information Modeling : Free Open Source Software Perspective

Introduction. The Information Technology (IT) has been able to expand its roots to vast fields since last decade. Every profession seems to be greatly influenced by it and the Architecture Engineering Construction and Operation (AECO) industry is not left behind either. The advent of Building Information Modelling (BIM) has been a boom for this sector. Gone are the days of manual drafting and 2D CAD drawings. The philosophy of BIM has inspired many leading software vendors like Autodesk, Bentley, Trimble, Graphisoft, Nemetschek, etc to develop the modelling software based on the principles of BIM. The AECO industry professionals are very well aware of these commercial products and have adapted them in their day to day services. Majority of prevailing companies delivering CAD services have transformed themselves into BIM organizations and many new companies have also emerged in the industry with BIM tags.

Complementing BIM and Lean in our AEC Industry

Introduction. Architecture, Engineering, Construction (AEC) is a very versatile and dynamic sector. Events, resources, processes associated with it are always unpredictable. This uncertainty invites prospectus of risks associated with it and seldom jeopardizes quality commitments made to clients at the time of entering into a lawful agreement. The sector is labor intensive and suffers highly from occupational risks and safety hazards unlike other sectors.

Unlike manufacturing sector, construction projects and associated products are always unique and diversified. These projects may be construction of an entire new facility or improvement/changes in existing facility. However, there still exists some element of similarity between the two sectors when certain packages have repetitive activities involved, like: (1) Casting of columns, beams & slabs of subsequent floor levels a high rise residential tower; (2) Casting of pre-tensioned girders for a long span bridge, and many such cases. Hence, proficient techniques which are being implemented as part of Production Management System (Maris et al. 2016) in manufacturing hubs can be aptly deployed here as well.

Augmented Reality and what it means to the Construction IT community

Introduction. As our world becomes increasingly digitized, so does our ability to connect with it. Imagine if you could search your surroundings the same way you search the web. Augmented reality(AR) is one such technology which enables us to interact with the real environment. The recent Apple keynote gave us a real sneak peek into how common augmented reality would be in the future. 10years back Apple showed us a device, which revolutionised the way how we interact with technology. And now, 10 years later, there is a high probability for AR to bring on a new revolution on how we interact with the digital world. Some of the readers of this article might have a question in their minds, “what is Augmented reality?“ Augmented reality is the real-time integration of digital information with the user’s environment. Unlike virtual reality, which creates a totally artificial environment, augmented reality uses the existing environment and overlays additional information on top of it. An explanation of augmented reality cannot be complete mentioning the reality virtuality continuum. Figure 1 represents the reality virtuality continuum as proposed by Milgram et al.(1995). It defines augmented reality in a space between a completely modeled and an un-modeled world i.e. in between a real and virtual environment.

BIM and Artificial Intelligence

Introduction. Dear friends, we all know pretty much about Building Information Modeling (BIM) by now. BIM over the last decade and a half has totally transformed the construction industry. The way construction industry worked during 1990’s and the way it works now is totally a contrast when one compares some aspects of  designing, drawing generation, communication, collaboration, etc. So where is BIM heading to when the world of Information Technology (IT) is heading towards Artificial Intelligence (AI). Is ‘BIM’ an ‘AI’ or can it be ‘AI’?

BIM implementation in India

Introduction. In India, Architecture, Engineering, Construction and Operation (AECO) industry is the second largest industry after agriculture industry. Indian AECO industry employs more than 35 million people, has second highest inflow of foreign direct investment after services sector, and contributes to about 11.1% of India’s GDP (Mohideen 2015). Recent initiatives set by Indian government, such as Make in India, is serving to grow the AECO industry. There are many mega projects undertaken recently, e.g. high-end road ways or express ways, metro train projects and proposed bullet train project between two cities of India, i.e. Mumbai and Ahmedabad. The initiation of these projects necessitates focus on various technical and non-technical aspects along with technologies, especially the infrastructure for these initiatives (Amarnath et al. 2016).

Benefits of diffusing BIM technology and workflows in AECO projects.

Introduction. There are several benefits of diffusing BIM technologies and processes with set of protocols adopted while delivering Architecture, Engineering, Construction and Operation (hereinafter AECO) projects. Few of the uses while diffusing BIM in the process of delivering building projects (well known as BIM Uses) are improved visualization, enhanced planning, accurate cost estimation, model based simulation and analysis, construction tracking, safety planning, etc. BIM Uses are the project deliverables that can be expected from the process of generating, collaborating-on and linking the building models to external databases. In simple words, the BIM Use represents the interactions between a user and a modeling system to generate building model-based deliverables (Source: The BIMe Dictionary). 

For the BIM project to be successful, it is well known for the Global AECO industry that, BIM project and its deliverables are the end products which needs to be delivered by the AEC organizations to the owner organizations as expected. And, it is essential to confirm that: which are the BIM uses expected by the client? What BIM tools need to be adopted while delivering expected BIM uses? Who are the stakeholders need to be involved while delivering each of these BIM Uses? In which stage of the project does these BIM Uses delivery occur? How to deliver these BIM Uses asper client expectations? And many more questions arise that needs to be answered during the BIM project delivery.
