Benefits of diffusing BIM technology and workflows in AECO projects.

   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.

To understand BIM Uses and how to deliver it in BIM projects, we had performed BIM Uses related literature review. This literature review reveals us that there are currently nine BIM Uses publications available (see able 1). Initial work towards BIM Uses was in year 2010 and more recently i.e. from last two years there are several publications that discuss about BIM uses and how to deliver it to the client’s expectations. From table 1, one can gain an understanding towards available BIM Uses publications, year of development, country of origin and number of BIM uses that has been explored in each of these literatures.

Table 1. Existing publications on BIM Uses.

BIM Uses    Year Country Number of BIM uses
VA BIM Guide 2010 USA 19 BIM Uses stated and only 10 defined
New York city BIM Guide 2012 USA 15 well defined BIM uses
Penn State University 2013 USA 25 well defined BIM Uses mapped to four phases
Finland COBIM Standards 2014 UK 12 loosely defined common BIM requirements across phases
Succar’s framework 2015 Australia 73 well defined BIM Uses organized in 7 model use series
DCAMM BIM Uses 2015 USA 51 well defined BIM Uses
Mass port Authority BIM Uses 2016 USA 51 well defined BIM Uses
PANYNJ BIM Uses 2016 USA 48 BIM Uses and none defined
HARVARD UCMC-BIM Uses Guide 2016 USA 20 well defined BIM Uses with 108 sub BIM Use categories within

And, the BIM Uses associated research by Badrinath et al. (2016) reveals that, the BIM researchers had discussed on benefits achieved in building’s project life cycle with the use of BIM. BIM researchers had documented the BIM Uses within different phases of a project (CIC 2011; McGraw-Hill Construction 2012; Kreider & Messner 2015; BIM ThinkSpace 2015). Few client organizations such as Division of Capital Asset Management and Maintenance (DCAMM), Mass port authority (MPA), Harvard university Construction Management Council (Harvard UCMC) and Penn state university (PSU) are expecting BIM uses delivery in their projects with a standard process applied by the contractor organizations. To date, several construction projects which has integrated BIM in their project’s process have reported the benefits from the use of BIM technology, and BIM is recommended as the solution for project performance and productivity issues (Mihindu & Arayici 2008; Eastman et al. 2011; Li et al. 2014).

Globally, several AEC organizations are delivering projects with the adoption of BIM tools & techniques in design and construction process. It is very much clear that, there exists a well-defined BIM project requirement from the client organizations and with distinctly available BIM uses for the AECO projects. It is essential for the AEC organizations to realize: what benefits of BIM has been expected from the owner organizations? And, what level of BIM in project has been delivered by AEC organizations? Gaining understanding towards these questions profits both the AEC and Owner organizations.

To gain further understanding towards existing BIM Uses and available database (BIM uses publications), we had compared BIM Uses in the existing six out of nine BIM uses framework, standards and guidelines, i.e. from Bilal’s BIM Use framework, Massachusetts port authority BIM guide, DCAMM BIM guide, Harvard University BIM use guide, PSU-BIM uses classification and, the port authority of NY & NJ-BIM standard (see table 2 for sample view).

NOTE: In the process of mapping we had considered BIM uses from Succar’s framework as the initial list of BIM uses and then mapped them with BIM uses of other six framework, standards and guidelines.  This table in here showcases only three BIM uses mapping as a sample list and other BIM uses were mapped in similar manner. This mapping process is based on the brainstorming sessions performed by the authors and further discussions with domain experts for validation purpose.

Detailed analysis of the BIM uses in these BIM frameworks, standards and guidelines revealed that there are currently 75 BIM uses defined. We had also performed the process of mapping similar/repeating BIM uses in all the six publications, we found that: (1) 34 BIM uses were found common in all the six publications; (2) 22 BIM uses were found common in five publications; (3) 6 BIM uses in 4 publications; (4) 5 BIM uses in 3 publications; (5) 4 BIM uses in 2 publications; And, 4 BIM uses were found only in one publications. It is our belief that, the thirty-four BIM uses that were found in all the six BIM uses publications can be considered as most commonly used BIM uses in AECO projects.

  1. My spouse and i were absolutely satisfied when Ervin managed to finish off his basic research out of the precious recommendations he obtained when using the blog. It’s not at all simplistic just to happen to be freely giving tips and tricks a number of people might have been selling. We discover we now have you to appreciate for that. The specific explanations you made, the straightforward site menu, the friendships your site make it possible to create – it’s got everything spectacular, and it’s aiding our son in addition to our family believe that that matter is pleasurable, which is extremely serious. Thank you for all!

  2. That is the fitting weblog for anyone who wants to find out about this topic. You notice so much its virtually arduous to argue with you (not that I really would need…HaHa). You positively put a brand new spin on a subject thats been written about for years. Great stuff, just great!
