3. The Dutch construction industry (1)
Represents 4.5% of the GNP and includes a production of 60 billion Euro
‘Conservative’ and non-innovative
Cost of failure counting for 5-13% of the annual industry’s turnover
A large number of SMEs and self-employed workers

4. The Dutch construction industry (2)
After an economic crisis between 2008 and 2013, the direction changed – construction production grew with an average of 7% in 2016
Familiarity of many Dutch construction firms with Lean and SCM, and enthusiasm for the implementation of its principles

5. Problem statement
Barriers to collaboration; highly adversarial and fragmented approached to relationships
Lack of performance

6. Construction production (1)
- Production-related characteristics (Broft & Koskela, 2018)
Converging logistics to a common, fixed point
Temporary and non-repetitive, one-off construction projects produced through repeated reconfiguration of project organisations
Multiple and concurrent project
Engineer-to-order production strategy

7. Construction production (2)
- Production-related characteristics (Broft & Koskela, 2018)
Based on two types of processes: small batch process and job process
Worked on by several work stations at the same time in suboptimal conditions

8. Lean Supply Chain Management
- The entire value stream (Broft, 2017)
Lean production contributes to eliminate unnecessary complexity
In Lean SCM, the entire flow from raw materials to consumer is considered as an integrated whole, where the interfaces between the different companies are thus seen as articifial
