Why Last Planner® System and Building Information Modeling First?

I will begin with discussing the history of lean thinking and then discuss the most compelling and promising tools enabling lean thinking.
The very concept of lean construction originates from Taichi Ohno's innovative management philosophy - Toyota Production System (TPS). Precisely, the same Toyota Production System is known as "Lean" in western world.
Ohno states in his book - Toyota Production System- Beyond Large Scale Production - the two most important building blocks of TPS are Just-In-Time (JIT) and Total Quality Management (TQM).
JIT in a layman's words is an approach with the objective of producing the right part in the right place at the right time. And TQM is a management philosophy that seeks to integrate all organizational functions (marketing, finance, design, engineering, and production, customer service, etc.) to focus on meeting customer needs and other organizational objectives.
Last Planner® System (LP®S) of production control is a tool based on JIT philosophy. Frequently applied by lean constructors in planning process and more precisely in scheduling process. LP®S encompasses the principles of JIT and utilizes the concept of Kanban too. LP®S makes plans more reliable and it is a building block of lean philosophy into construction just like JIT in TPS.
Second building block of TPS is total quality management (TQM) that is concerned with quality management, as the name indicates and for doing so its focus is on value creation. Repeat work is a big waste in Ohno's book that we all agree. Rebuilding a wall wrong built or redoing the MEP tasks because of defective drawings and so conflicts is certainly waste and poor quality management. Building Information Modeling (BIM) is a technology that enables integration and visualization of the facility in virtual world. Contractors use BIM to detect conflicts and Architects use it to communicate their design rationale to all the stakeholders.
Lean is a philosophy but you need methodologies and tools to make lean a reality. Last Planner® System and Building Information Modeling are serving the purpose. Despite several cultural, training, educational, leadership, contractual and legal barriers these innovations are diffusing in the construction industry.

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…

Data Driven Design and Construction - Answers to Randy's questions

Randy started a new blog that will focus on Data Driven Design and Construction. He asked few questions in his first post. Here is my take, feel free to comment. I recommend you should follow his blog. He will be coming up with a book on this topic next year some time. I can't wait to read it. Here are his questions and my answers - 
How do we, as a discipline, capitalize on data and metadata to drive innovation in architecture and construction, just as other disciplines and industries have?Evidence based design is one of the leading fields of research that will eventually result in data driven design and construction. Understanding the end user requirements better and designing products that reach to the highest level of customer satisfaction would require data driven design. On technology front, building information modelling (BIM), virtual reality and augmented reality will help collect the data related to customer requirement. Moreover, when construction is in progres…
