Lean Design and Pre-Construction

• transformation of inputs to ouputs
• conformance to design & specs
• fitness for use

identify waste and eliminate it upfront and identifies means for adding value.

it documents how is work currently done and proposes a new flow describing how users wish to operate it in their new facility.

evaluating alternatives and deferring design decisions to the last responsible moment.

• conceptual design
• product design
• process design

• T  tightly couple action and learning
• I  ncrease relatedness
• P  roject as network of commitments
• C  ollaborate - FOUNDATION OF LEAN DEFINITION!!!
• O  ptimize the project, not the piece

• operating system (how work gets done)
• organization (relationship structure)
• commercial terms (contract)

• it identifies value early on and maximize it with less cost spent later on to remove waste.
• also, proposing using more economical materials or prevent including structures in design that are difficult or impossible to construct.

focus is producing a design that can be constructed with a defined budget.

includes the analysis of several constituencies and ensures all viewpoints are presented.

listing the advantages of each option

...a full scale prototyping that simulates the work environment

It leads to understanding what constitutes waste and what creates value.

• these are 2 different components in the process of delivering value to the Owner.
• Construction is a continuation to design just as design is the predecessor to Construction.
