Why LEAN? – The “way we have always done it” is not working

LEAN Principles and Tools • Waste- 8 Types • 5 S • Visual Work Place • Reliable Promises • Electronic Documents

What is Waste? 8. Under-utilized Talent

Waste in Construction Current Manufacturing Current Construction

5 S • Everything On Wheels • Nothing Hits the Ground • Subcontractor Laydown Areas • Continuous Cleaning • Sustaining the Plan

Visual Work Place Owner Signage - Include Project Goals or Condition of Satisfaction (Co. S) Boards and Lists- Get the files out of the computer and into the open • Clear Signage Restroom, Lunch, & Staging Area • Owner Signage Include Project Goals or Condition of Satisfaction (Co. S) • Boards and Lists • Color Coding Site

Visual Work Place Subcontractor laydown areas and S 5 organization Set expectation early and often. Get the information in places the field staff have access to it. Color Coding of Floor- Visual work is used in pull planning to talk about batch sizing. Establish flow and direction. Logistic plan should be posted on project.

Reliable Promises- Pull Planning provides project alignment and schedule buy in with subcontractors. Pull Planning is just a different way of running a foreman’s meeting Daily Forman Huddles. Tracking Percent Promise Complete (PPC) Breakout Meeting- Addressing Complex Issues in Smaller Groups

Reliable Promises- Constraint Log – a list of constraints with identification of an individual promising to resolve the item by an agreed date. Typically developed during a review of the Six Week Look Ahead Plan when it is discovered that activities are not constraint free. Theory of Constraints (TOC) is a management paradigm that views any manageable system as being limited in achieving more of its goals by a very small number of constraints. There is always at least one constraint, and TOC uses a focusing process to identify the constraint and restructure the rest of the organization around it.

Reliable Promises- Plan, Do, Check Act & A 3

Electronic Documents Everything Lives in the Cloud Electronic Documents provide the most current information to entire project team and reduce waste and rework. • E-Doc’s • Tablets - Including Subcontractor Foremen

Electronic Documents- BIM § Model as much as possible- The more the better § Maximize learning curve prior to work in field § Minimize variation created by errors
