LEAN Scheduling

Planning Planet Lean Construction Event

http://www.planningplanet.com/groups/500322/building-information-modell…

If you join the Building Information Modelling Group, we have Alan Mossman from the Lean Construction Institute giving a talk on this subject on the 1st November in London

http://www.planningplanet.com/groups/500322/building-information-modell…

The event is free to pp members

The Schedule Cracker software check the projects schedule for Lean and even calculates the sigma value (Six Sigma concept).  The Lean and Six Sigma is part of the schedule analysis and review process of it.

"The MOJ are currently using Lean Scheduling throughout their prison contracts" this is what I was talking about; actually I too am working on couple of prison projects implementing their lean techniques as lean planner.

Lean Scheduling covers a whole load of techniques. Bernard is right with his link, you could also try

http://www.constructingexcellence.org.uk/ I used to be on their lean task force. I would also search google for "last Planner" which is a collaborative planning technique where the person doing the work does the planning etc.. if you can cut through the stacks of management speak the system is very interesting and I have used this on a couple on contracts I have worked on recently. The MOJ are currently using Lean Scheduling throughout their prison contracts.

I think Lean Scheduling refers to applying Lean process improvement techniques to the scheduling process. I've also heard it called a CLIP review.

These techniques may include:

-getting all key suppliers, subbys etc involved in planning workshops

-using post its & string to map out the process flow (or as we call it, PERT)

-robustly challenging all asumptions used in agreeing the process flow & durations (do you really need ALL of my vendor details before you can do ANY work on designing the pump base?)

-Collaboratively identifying which party can achieve reductions in project duration for least overall cost/risk (yes I could airfrieght you the pump instead of shipping, but wouldn't it be cheaper for you to double your process design effort?)

-Actively pursuing means to limit the 7 types of waste identified in LEAN methodology (overproduction, unecessary transport, inventory, motion, defects, over-processing & waiting)

Hi David,

What I understood about lean is as some of our friends mentioned above, it is a way of thinking to construct something (it can be anything) with "right in time" and "zero waste" principles to achieve effective results (in terms of cost, quality and time).

The term lean scheduling “may be” referred to how you planned to implement this, actually there are some criteria defined by some lean experts to set up a lean program, monitor and report against the progress; I am working on few construction projects as a planner where we implement these criteria.

In my understanding, lean construction is just the resources being there at the right place & time whenever you need it, thus, maximizing the space & manpower used in transfering on resources from 1 place to another. My manager comes from a manufacturing field and teach me some basic principles regarding this concept. This is best applicable if the construction site has a shortage of laydown area and the materials can’t be delived by bulk.

If I understood properly what is meant by Lean construction it is exactly the same what I described in my posting. In this case I don’t understand why there is a need for the special term. We always use this approach (plan supplies together with the construction works) in construction projects.

Our software (Spider Project) supports Line of balance reports but it is not necessary for the proper planning. Much more necessary to be able to calculate construction schedule taking into account supply constraints.

David,

I think they are asking about how you will incorporate and manage lean principles in the construction process.

I don’t believe this answers your clients query, but some Lean practitioners are approaching construction planning, using a concept of ‘Location based planning’ using the principles of ‘Line of Balance’ planning. This is now being referred to as ‘Work Flow’ construction planning, and controlled using a proprietary programme developed in Finland, instead of the conventional CPM packages. The emphasis is on maintaining continuous work for each trade or part of that trade. Critical path type logic and lean construction principles still apply.

There were papers related to this topic given at the 13th Conference of the International Group for Lean Construction, held in Sydney this year.

Greg

I haven’t heard of "Lean Scheduling", but Lean Project Management is a system being promoted by the Lean Construction Institute.

I did not meet the term Lean Scheduling.

But Just in time management is usual.

If you build something in a place where there is not enough space for storing materials you will schedule supplies together with the construction works.

Construction work schedule defines the necessary amount of materials at any moment. If there are changes or problems with the supply then PM software shall recalculate the schedule of construction.

For just in time PM you shall include both construction works and supply schedule in one single model.

Hi,



It might be similar to LEAN Concrete (Blinding).Blind....
