#3: Automation and Demming's PDCA Cycle in Construction Management

In 1986, Dr. W. Edward Demming, author of the infamous book "The Toyota Way," which has become one of the great inspirations for our team at Vico, defined a model that applies to virtually every imaginable process. It is often referred to as the "Demming Wheel" and consists of a circle divided into four equal parts, each one representing a typical phase for a management process: Plan, Do, Check and Act.

 

People who work in construction management jobs go through this cycle numerous times per day. They "plan" what needs to be done next, "do" the required things to make that happen (attending meetings, placing phone calls, sending e-mails), then "check" if everything is going according to plan and finally "act" if something is not going according to plan, after which the cycle restarts.

 

It is typically the third phase in the PDCA cycle - the "checking" part - that is taking a disproportional amount of time from construction managers. The vast amount of both paper-based and digital, but foremost disconnected information that provides them with project status updates requires a lot of processing time.

 

It is common sense that the human brain is limited in its capabilities to process large amounts of data and to subsequently derive an objective view on the actual status of a project. It is therefore, that jobs in construction management require many years of experience and exceptional skill sets in order to make sure that projects are completed on time and with the desired quality by interpreting available information the right way. The majority of people that are currently occupying these crucial jobs in the construction world are from the "baby boom" generation, which is expected to retire over the next 10 years.

 

The challenge that the construction industry is facing today is to make sure that the "C" in Demming's cycle is going to be performed successfully in the future as well. That is: after the people with the exceptional skill sets and years of experience that are running projects today will have left the site. Automation and smart reuse of knowledge seems to be the horse to bet on.

 

Vico is working on a number of initiatves with our Partners to assure more streamlined processes.  First, we have built Vico Office as a BIM-neutral platform.  This allows users to publish BIM files from Revit, Tekla, and ArchiCAD (no re-modeling, no waste).  Secondly, working with Trimble's LM 80 and Total Station, users can plot points inside the BIM which can then be placed out in the field.  Conversely, points in the field can also be marked and overlayed on the BIM for a comprehensive quality check.  Thirdly, CMiC and Vico spread the information contained in the 5D BIM to the various departments throughout the contruction firm, keeping the bottleneck of change management under control.  Finally, Vico Control allows superintendents to walk the jobsite and note the percentage complete, allowing immediate "action" in the PDCA cycle. 

 

Companies that successfully implement systems that allow for deriving project status instead of contriving it, will be prepared for the future.

 

What is your firm doing to institute lean construction methodologies?  To institute BIM or other technologies to make production control and "checking" more streamlined?

Chakib, you are right. Deming is the person behind 'the Toyota way', but did not write the mentioned book. Thanks!

Mr. Broekmaat, one of the big missing LEAN components in current construction practices is a visual management system, and I personally do not think that a GANTT chart counts as a visual management tool. I think that VICO offers "line-of-balance" planning tool, but unfortunately, a computer screen is only a visual management tool when it is turned on and all the workers are gathered around it! I have some ideas for charting that are "not BIM" but can rely on BIM technology. Until the model gets out of the computer and visually into the field, BIM will not have the impact it needs to have!
