The document discusses lessons learned from a study on applying lean thinking and integrated project delivery (IPD) to healthcare construction projects. It found that full-scale mockups were the most effective lean strategy. It also found that learning was an important implicit benefit not tracked. While IPD led to benefits like collaboration, some challenges included perceived imbalance of influence and optimal use of lean strategies. To fully evaluate the costs and benefits of lean-IPD approaches, factors like time costs for additional participation and documentation need to be accounted for.

Lean Construction reduces waste and adds value using continuous improvement in
a culture of respect
Adapted from Rybkowski, Z. K., Abdelhamid, T., and Forbes, L. (2013). “On the back of a cocktail napkin: An exploration of
graphic definitions of lean construction," Proceedings of the 21th annual conference for the International Group for Lean
Construction; July 31-August 2, 2013: Fortaleza, Brazil, 83-92.
8. VALUE =
What you get (benefit)
What you give (cost)
Saxon (2005)
Value is greater than 1 when Benefits exceed Cost and less than 1 when
Costs exceed Benefits. We need to consider time value of money.

management that ensures that new products and services
meet market determined price and financial return.” (Ansari,

Compared to architects, general

Design can add more value to the
overall project was significantly higher.
35. For Architects & Engineers, GC is perceived as having more
influence than the owner
Although theoretically an Integrated Project Team should have
equitable influence, It is not perceived as such by all stakeholders.
36. Architects perceived themselves with lower levels of
influence compared with owner and general contractors
who perceived their own influences higher than average
Self-perception
37. Architects perceived themselves with lower levels of
influence compared with owner and general contractors
who perceived their own influences slightly higher than
what others perceived.

41. Cost savings opportunities are present in
three phases :
• Validation
• Innovation (design)
• Production
ROI Implication:
In order to calculate Return on Investment, incremental costs must be itemized and considered as well.
cost contributors include material (Lean facilitation in workshops and documentation, and mock-up
construction), labor (considerable additional time for all participants), equipment (mock-up support), and real
estate required for team week meetings and co-location, as well as a full scale cardboard mockup. There
are also indirect and overhead costs associated with these items.
Focus for this study
42. • Learning: A tremendous implicit benefit which is not tracked
– Team, User and Community
– An implicit benefit that is not currently captured
• The cardboard mock-up workshop – the most successful lean strategy
• More accuracy needed in estimation
• Owner perceived as having the largest influence in the process, followed closely by the
General Contractor.
• Quality is a key component of value but robust measures to access quality are lacking.
Greater value can be a result of greater/ same benefit with lower costs.

45. To translate these success metrics into an ROI, three
additional components are needed, namely:
• A baseline of benefits and costs in comparable traditional Design
Bid Build projects to allow a benchmark for comparison
• A more thorough documentation of incremental (additional) costs
associated with the decision- making process involved in a Lean-
IPD project
• An assessment of the long-term/ occupancy implications of design
decisions. This links to the field of Evidence-based Design and must
be investigated further.
