• Adjunct Professor Stanford University
• Director of R&D at BoKlok (Skanska + IKEA)
• PhD from Lund University, Industrialized Construction
• Backgound: Structural engineer, Logistics Consultant, Advisorto building companies
• Worked with IC for 20 years
Industrialized Construction in history
• Single-family houses follow a long industrial trend
• 80 % are built with IC methods, using wood frame technology (since 1920s)
• Links to the timber industry
• 10-15 companies dominate
• From extremely standardized to custom-built
• 25.000 houses annually
• Largest companies build 1500 houses per year
Industrialized Construction in history
• Extensive development during 1960’s
• Focus: Prefabrication and Building Technology
• Large-scale housing projects
• Dominating productionparadigm: Mass production
• Scarce customer focus!
• When the market went down, IC was abandoned
-For a while…
Recent development: early 2000’s
• Strong focus on Industrialized Construction –multi-family buildings
• All major construction firms launchedprograms and several built factories
• Also small & medium companies wereestablished (specialized)
• New understanding of IC
• Academic research supported the industrydevelopment
• Complex production systems

What have we learned?
• IC is complex and takes time
• Require new business models and strategies
• Specialization is crucial
• Balance investments and market volume
• Integrate product- and production systems
• Use customer needs as starting point
• Platforms offer a structure for design and technicalsolutions
Two platform strategies dominate
1. Generic Platforms for increased efficiency
The company’s performance is improved
Technical solutions structured in platforms
Process support: BIM, Logistics, Planning
Increased use of prefabrication
Traditional contracting offering
2. New concepts are offered the market
Product offering companies
Complete customer offers
Specialization in defined product ranges
Optimized production systems
THE LAST 2 YEARS:- ACCELERATED DEVELOPMENT
• Platform based construction – Concepts for unique projects
• Product and concept offerings – Module factory production
Generic platform development
• Big investments in Cross Laminated Timber
• New actors enter the industry
• Developed by timber companies
What does this give us?
• Interesting alternative to concrete
• New actors can leverage on these platforms
• “Chassis” to create product concepts on
• Structural solutions for higher buildings

PRODUCT PLATFORMS AND COMPLETE CUSTOMEROFFERS
• Big investments in Module factories
• Both new and existing factories
• Specialized companies
• Investments done after years of trying the concepts on the market
20% of multi-family building are built with IC-methods
More potential left
We have unique knowledge and experience
Sustainable and energy efficient solutions
BUT: Only focusing on Sweden - one of the smallest markets in the world…
I think we should start expand our market!
Excellent opportunities
Study trip to Sweden
Ideas are born when people meet!
-We are planning a study trip to Sweden
Thank you!
