The Last Planner System®Trending

Benefits Of Using The Last Planner System® Fact Sheet

 “Our construction industry suffers from a lack of collaboration due in part to our project teams’ inability to communicate in an effective manner. The Last Planner System® promotes healthy communication and it works!”

– Terry Brickman, Vice President Quality Management & Lean Transformation, PCL Construction Enterprises

Variability of labor cost due to productivity and schedule delays is the most likely factor to cause project
cost overruns. A productivity study from Professor Paul Teicholz from Stanford University in 2013
shows how construction labor productivity has declined 0.32% annually from 1964 through 2012 and
the gap in productivity between construction and other sectors of the economy has doubled in the last
decade. Construction project costs typically are split evenly 50/50 between labor and materials. A study
by the Construction Industry Institute in 2004 observed labor productivity of construction crews
ranging from 8 to 25%. Other case studies have observed typical labor of productivity at 30 to 35%. It
follows that if half of the cost of a project is tied to labor and productivity is less than 35%, then 30% ir
more of the project value may be tied to non-productive activities resulting in lost profit and higher
costs to the owner.

The Last Planner System (LPS®) of production planning developed by Greg Howell and Glenn
Ballard in the 1990s has been growing in use over the past 15 years on projects all over the world.
When used properly LPS can dramatically improve productivity and contribute to significantly better
project performance. It does this by engaging those that will actually be conducting the daily planning
of the work on the job, the superintendents and foremen or Last Planners, through a series of
interconnected commitments in a highly visual environment. Howell and Ballard learned through their
search that on average 54% of what was planned on a weekly basis by superintendents was actually
completed. Using LPS, this completion rate moves into the 80 to 90% range weekly for
high-performing teams.

A Brazilian LPS study involving 16 companies in 2010 reported that 95.5% of the participants were
more satisfied with using LPS over previous planning and control techniques such as Critical Path
Method (CPM). The interviewees’ perceptions of the effects of LPS versus traditional methods are
displayed below.

Reducing  project  schedules  and  cost  through  Last  Planner System

  • The $645 million California Department of Corrections and Rehabilitation California Healthcare Facility was delivered in 2012, 5 weeks early using LPS. The project only started using Last Planner System 22 weeks before the completion deadline in order to double daily work in-place from $1.5 million/day to $3 million/day to meet the finish date.

  • The Kaiser Permanente Oakland Hospital Replacement Project finished 3 months early and won ENR Best Health Care project in California in 2014 using LPS.

  • John Wayne Airpot, Terminal 3 in Santa Ana (CA) and the  £4.5 billion UK Heathrow Terminal 5 project were both delivered on time using the Last Planner System.

Common  Takeaways  from  Last  Planners

General conditions account for a significant portion of every project budget ranging from $2,000 a
day in smaller projects to $50,000 a day on larger projects. Costs are incurred for field staff including
superintendents, project engineers and field administrative support as well as trailers; utilities (water,
power, communications); site security; office supplies; insurance; trade partners and owner
representative salaries and expenses, equipment & machinery rentals, and financing. These are all
direct savings from finishing on time or early. The earlier the finish, the greater the savings.

Other studies indicate projects using the Last Planner System have many other benefits including:

  • In a Brazilian LPS study in 2010 involving 16 companies greater planning process transparency and task visualization (26.2%) and improved site organisation (23.1%) resulted in improvements in team organization and site safety.

  • Site workers become more productive. Bricklayers increased their productivity from 108 sq. ft./worker/day to 178 sq. ft./worker/day while also using load leveling and material visualization tools.

  • Better collaboration, communication and understanding happens as foremen and superintendents become more engaged. Teams become more accountable as they commit to plans and decisions that they are making in front of their partners. They are now looking out for each other. “LPS opens up the lines of communication” and “Why tell one subcontractor what another is doing, when they can do it themselves.”

  • Reduced buffer time in schedules or “sandbagging” by trades as trust builds and reliable commitments are met.

  • Good process for trust, camaraderie and communication building, understanding other team
    members work and achieving buy-in to plan. Transparency helps to identify constraints and
    interdependencies of  tasks.

  • More stable workflow and better matching of available labor force and other resources increased
    plan reliability  and  decreased  the  number  of  emergency  requests  for  resources  and 

  • Root causes of  issues  are addressed in a timely manner  with  development of effective

  • Reduced risk of liquidated damages, associated legal costs and lost capacity to do work for other

  • Reduced risk of liquidated damages, associated legal costs and lost capacity to do work for other customers. Speedier RFI replies and submittal approvals by involving the design team in LPS increases reliable work flow and reduces delays.

  • Punch lists and rework are significantly reduced because the work is accepted or rejected at the handoff between trades. Therefore, defects do not continue down the line.

  • Last Planner System is the gateway to Lean behavior regarding collaboration; identifying value and waste; participation, communication and transparency; trust building, reliable promising and clear commitments; goal-driven behaviors; systemic thinking and root cause analysis; learning and continuous improvement; short and long term planning; and promoting flow, small batching and a visual workplace.

Common  Takeaways  from  Last  Planners

  • Good  team  coordination  and  cooperation.
  • Last  Planner®  success  is  dependent  on  teamwork  and  solid  commitments  being  kept.
  • Good way to keep  everyone  accountable  and understand  each  other’s  scope  of  work.
  • The  visible  aspect  of  the  pull planning wall and weekly work plans  are  really  helpful.
  • Good  to  meet  and  see  who  all  the  project  players  are  before  commencing  on  site.
  • Standing  up  and  working  at  the  wall  kept  the  attendees  focused.
  • LPS  can  benefit  the  whole  project  especially  in  design/build,  design/assist  and  IPD.
  • Reverse  planning  (Pull  Planning)  can  more  fully  identify  constraints.

“Without a mid-course correction from conventional CPM look- ahead schedule management to Last Planner, it would not have been possible to complete the project early. And we certainly would not have produced a $60M month, the largest on a State project in history.”

– Mike Ricker, Vice President, Clark Construction on the California Health Care
Facility, California Department of Corrections and Rehabilitation, Project in Stockton, CA.
