Jan 28, 2015 -- BIM, big data, data analytics, Business intelligence, mobility etc are some terms that have been highly used and abused. The latest to join the bandwagon is lean BIM. The mentality is that just because Lean is in, and everyone is adopting lean construction procedures let us also do it.
Now cheap can cost you more in the long run, and to think that lean is equal to cheap – is the basic folly. While lean construction can be used to derive the best business benefits, if your concepts are wrong, there are chances of some dismal failures.
So let us first understand what Lean actually means! Lean is a concept first adopted and applied in the manufacturing industry.
It is not a tool or a technique, lean is a philosophy or say an approach towards processes like manufacturing, and in our case construction. While it is true that several people have tried to adopt lean construction and failed, and so is the case with other popular technologies like BIM and energy efficiency. While there are lots of failures, there are also several Lean Practitioners who have successfully adopted Lean philosophy and gained optimum benefits.

The key to deriving benefits from Lean philosophy lies in Interaction of Lean Construction and BIM. Lean is an approach that focuses on cost cutting, but not at the cost of form or function or the quality. So then what does it focus on, how Lean Construction Complements BIM and how cost cutting in a construction process happen?
To better understand lean construction let us understand the principles on which the lean philosophy is based. The 5 principles of Lean are
- Value - Accurately identify the value you will be delivering to your customer – understand the customer perspective
- Value Chain - Identify the non value added process and eliminate them
- Flow - The other steps that have been identified as high value process, should follow each other without interruption in the most efficient and seamless fashion
- Pull - Get to work and deliver highest productivity at the shortest turnaround times, only once you get the necessary approvals.
- Perfection - Maintain best quality by utilizing resources in the most prudent way and continually keep improving.
What is Lean construction not about?
Lean construction is not about stripping down your requirements to the bone and then squeezing the most out of it. It involves a close scrutiny of the smallest details and a focus on smallest areas of operations and an emphasis on performance measurement and optimization.
