Building Information Modeling (BIM) and Lean Construction for successful project management

Recently I came across this article by Dennis Sowards "BIM and LPS improve project management". Dennis explained LPS-Last Planner System and Building Information Modeling (BIM) fairly well.

However, in my opinion there is no point in asking the question "Should we choose BIM over Lean or Lean over BIM?" As Dennis explains in the article that before asking this question "you need to consider what each process offers before choosing one over the other", I would say: lean is a management philosophy and BIM is a technology for effective management of project information. In other words lean is a way of management and BIM is a tool for management.

Lean construction is based on a simple principle "reduce waste and increase value." To reduce waste (of time, material, labor etc.) a number of initiatives have been taken, for example Last Planner System (LPS) of production control, Value Stream Mapping (VSM), Target Value Design (TVD) etc.

If we closely look at these tools, techniques and methods developed over last two decades the sole aim of these tools is to reduce waste and increase value of a project delivery. This goal translates into the goal of continuous improvement.

At this point this question can be raised "Where BIM comes into picture when we talk about lean construction?" As I said the sole aim of lean construction is continuous improvement, BIM is a tool that brings improvement to the process of project delivery- and thus continuous improvement.

Traditionally design information is shared using 2D drawings. The waste embedded in the process include: change orders, poor information flow, rework etc. BIM does not eliminate this waste entirely but it reduces the waste and so BIM enables lean.

LPS is a tool used for planning purposes, with a goal of making plans more reliable. Making plans more reliable is very important if we look at the waste generated due to broken promises. On the other hand LPS enables integrated project delivery, because "last planners" (foremen/supervisors), GCs, architects, engineers, and trade partners collaborate to make plans more reliable using LPS. Collaboration and integration is the essential condition for the use of LPS.

In conclusion lean construction philosophy and building information modeling technology both are essential to emerging building industry which is facing a downturn due to financial crisis and which is more conscious about sustainable and green construction than it was in the past.

  1. Thank you Vishal. Among us, more needs to be discussed about BIM, Lean and IPD. Keep it up!

  2. Everything is connected; we need to connect the dots to make the most of existing knowledge.

Business Case for Building Information Modeling (BIM), Lean, Green and IPD - What we can learn from an Economist?

Vijay Govindarajan recently caught attention for his recent book "The Other Side of Innovation: Solving the Execution Challenge" published by Harvard Business Review and his work on "Designing $300 Home". He is called the strategic innovation Guru and he is also the Earl C. Daum 1924 Professor of International Business at Dartmouth’s Tuck School in US. He believes that perspiration is more important than innovation i.e. execution of an idea is more important than only coming up with the idea itself.

I will try to explain the advantages of BIM, Lean, Green and IPD by his theory of strategic inovation. He talks about three boxes that large organizations operate into (or where organizations' projects fall into)-








Building Lean and Green using BIM and IPD fall under Box-2 and Box-3 that is selectively forgetting the past practices and creating the future (and here we are talking about 20 years from now i.e. about 2030).
Hear is his talk with Harvard Business Review -…

World's Tallest Building Sky City-1 Changsha China and BIM, Lean and Green - What might be coming?

I feel fortunate to be living in an era when there are Computers, iPhones, iPads, Androids, Google Glasses, Google Earth, Facebook, Twitter and Broad Sustainable Construction. All but the last one out of my list are pretty obvious and I do not feel explaining why they are awesome. However, I feel like talking a lot about Broad Sustainable Construction, a company which is based out of China and doing miracle after miracle and revolutionizing what world calls development. As a matter of fact, China is doing great with several other things too. But this blog won’t be talking about that.

At this very moment (January 5th 2013) Broad Sustainable Construction is building world’s tallest building – Sky City –1, which is almost a kilometer high (838 m/2749 ft to be precise) with 220 floors. They are set to complete the construction of this building within 90 days. This is remarkable and revolutionary. They claim to prefabricate 95% of building off site. Guess what, whole world is trying to bri…
