Mr. O. Arivazhagan, B.E (Honors), CEO ,IIPM, was invited to deliver
Special lecture on "Lean Construction Management”
at St.Peter’s College of Engineering and Technology on
14th Mar 2017 to the Civil Engineering and Management Students.
In his session on “Lean Construction Management”, Mr. Ari uniquely and practically conveyed to
the students from the two departments on the concept of “Lean”
by categorizing the topic into “Lean in Film Making”, “Lean in Construction” & “ Lean in Manufacturing”.
He used his handful of experience in Film Making to correlate the Lean concepts in an interesting manner
He addressed “Lean in Construction” as a combination of operational research and practical development in design and construction with an adaption of Lean manufacturing principles and practices to the end-to-end design and construction process. He said that the main goal is to maximize the value and minimize the waste at the project level is the goal, versus the traditional practice of attempting to optimize each individual activity, which would in turn result in better time productivity, reduced safety hazards and cost savings. As an example, he drew a Process Flow diagram of
“How Concrete Mix” is prepared and explained which of the steps involved were Value Adding & Non-value adding.
He addressed “Lean in Manufacturing” where he highlighted that
Single-Minute Exchange of Die (SMED)
is one of the many lean production methods for reducing waste as it provides a rapid and efficient way of converting a manufacturing process from
running the current product to running the next product. He also emphasized that It was one of the foundational blocks of a continuous, improved production flow.
The phrase "single minute" does not mean that all changeovers and setups should take only one minute, but that they should take less than 10 minutes (in other words,
"single digit minute"). The “Dies” refer to specialized tools used in manufacturing industries to cut or shape material mostly using a press, which need to be modified
and re-setup when a production model is changed. Changing dies could stop processes for an extended amount of time. He cited car racing which is used as a metaphor for SMED,
with process setups/changeover as pit stops. In fact, many of the pit stop tricks are used in SMED

He spoke about “Lean in Film Making”, which revolves around the core
principles of creativity through collaboration, story as top priority & a core tool in Lean Filmmaking is the use of
multiple cycles, where in each cycle you build a draft of the film, show it to an audience and learn what to improve.
He took a simple example in Film Making to demonstrate the Lean concepts to Construction and MBA students ;as he is also a
Certified Film Producer - Director, Hollywood Film Institute,
NewYork, USA & Producer - Director, International Dream Merchants (IDM),
along with directing 3 feature films in DVD format, he spoke about camera set up time during shootings, normally most of the time is
lost in camera set up due to which the waiting time for the artists increases.
He spoke about Maslow’s Hierarchy of needs – which is pyramid ,
starting at the bottom physiological, safety, belonging, esteem and self-actualization,
these basic necessities have changed and now has Wifi & WhatsApp included in the list.
The Students were impressed by how beautifully the Guest Lecture was given without talking about Hardcore
Construction or Manufacturing to explain Lean concepts in the various industries. In the final Question & Answer session; for the 3 best answers he awarded
the students with 1 USD, 20 Thaibaht & 2000 Indonesian Rupees respectively
