Earlier topic referenced "Building Information Model (BIM) a must tool for PM?"
Building Information Modeling (BIM) has recently emerged as an approach that achieves considerable improvement in efficiently handling project complexity. How truthful is this claim? Can we validate it by using the below analysis questions?
a). What are the main challenges within the current practice of your project management
b). What BIM-based project management has offered to those challenges?
Guys your opinion is highly appreciated... Saving Changes...

This is a new name for an old concept. As other thing which are there from long time ago today they received new names and has been put in place again because support technologies are cheeper and masive. As a tool, if the initiative can pay for it, it is critical to be used. As other things, what today is called "digital transformation" is about to change the way we do things but the core still remains. Saving Changes...
Such systems are of value within specific industries (e.g. large-scale construction) but they suffer from the same weaknesses as other enabling technologies including:
- a lack of fit with how work is actually done (i.e. process doesn't align with the tool)
- garbage in, garbage out. If the data within them is low quality, then the decision support they provide is also of limited value
On highly complex projects where there are many interactions between physical systems of the product and business systems to manage the project, understanding the totality of changes or impacts is very difficult.
Concepts like BIM enable a "digital thread" to connect the many interrelated pieces. Saving Changes...

This topic has got me reminiscing about my professional career and "modelling" in the construction industry. Started out on the drafting board where we used pencil and paper to provide two-dimensional modelling of the proposed installation/construction. Each discipline had its own set of drawings (mech, elect, civil. etc). We would set up working meetings to try and identify physical conflicts making sure the piping, cabling and supporting structures achieved the desired results with least re-work in the field. We relied on the trades to read and interpret the drawings, make final adjustments and document the actual installations.
From here we went to physical models where the modellers worked from the drawings and created scaled versions so that the trades could visualize what we wanted to achieve - looked at the drawings, checked the model and said "aha" that's what we are trying to build". Helped considerably but expensive and not fool-proof.
Next step was CADD - computer aided design and drafting. This allowed us to identify conflicts and determine best (most effective) routing prior to actual installation. However, the requirements were provided to the trades in two-dimensional drawings most not having access to, or having necessary expertise with, the digital model. Field adjustments remained "red-line drawings" which the CADD operator used to update the electronic model on project completion.
After 50 years I see BIM as the current state of modelling but not the end state. Modelling not only the deliverable but the delivery process.
It's been a grand trip. Thanks for the opportunity to relive my travels.

I had a similar journey starting as an engineer when hand drafting was being phased out.
In recent times, the latest CAD systems have integrated the graphics with the specs, parts list, and instructions. You can just click on the model to "interrogate" it for the supporting information on any PC with an installed app.
That can be problematic though. We sent instructions for a major retrofit project to a customer in Ethiopia, only to discover their mechanics don't have computers at their shop. The office workers print out the old style drawings and associated paperwork. It was both frustrating to them and embarrassing to us. Suddenly we had to figure out how to convert all those digital models into something that could come out of an inkjet printer.
Just because you have the technology, doesn't mean everyone can use it! :-)
