Industrialized Construction- An innovative approach to Construction
J. Lessing
Characteristics of construction
• All building projects are unique• All project teams are unique• All projects are built with unique technical
solutions• Our industry build prototypes – every time!• The ”products” are complex• The building process is fragmented, many
actors and many interfaces• Profitability is low• We have quality problems• Etc• Etc
J. Lessing
Effective production environment?

High performing production facility?

Potential for innovation!?
J. Lessing
• One solution is to industrialize construction• New methods and new technology are being developed• Processes for stable and predictable outcome are established• Interesting examples are developed in Sweden, Japan, UK, U.S
J. Lessing
- But what is industrialized construction?
J. Lessing
What is it about?
• Adopting principles for effective design production apply these on construction
• Leading paradigms; Lean Production, Agile Production, Supply Chain Management focus on customer value, minimizing waste, flexible manufacturing, and efficiency through the whole supply chain – Inspiration!
• Modularization and Automation are important parts • Principles and methods are applied on construction today, to
achieve higher efficiency, higher quality, lower costs and increased sustainability
J. Lessing
Prefabrication
Automation
Factory production
Assembly
Standardized processes
Materials handling
Advanced IT tools
Building systems
Standardized technology
J. Lessing
Historical view of the concept
• Focus on Prefabrication and Technology
• Prefabrication of building parts, applied on large scale housing projects
• Dominating production paradigm: Mass production!
• Scarce customer focus!
J. Lessing
Today’s view of the concept
• Customer oriented• Utilizing modern Information
Technology • Increased focus on the holistic
process, not only the specific building project
• Buildings are treated as customized products in a continuous process
J. Lessing
1. Planning and control of the process
2. Developed technical systems3. Prefabrication 4. Long-term relations 5. Logistics integrated in the building
process6. Customer and market focus7. Use of ICT8. Systematic re-use of experience
and measurements

J. Lessing
A tool for strategic analysis of the whole production system
A good fit between the parts is required
-In order to deliver what the customers want

Industrialized house building in Sweden
• Sweden is one of the leading industries globally in terms of maturity and adoption of industrialized house building concepts
• Single-family houses follow a long industrial trend and 80 % are built with industrial methods, using wood frame technology (since 1930s)
J. Lessing
• A large number of small and medium-sized companies offer a wide variety of houses
• From low-cost to high-end• From standardized to custom-built• 100 companies, 5000 employees• Produce approx 10.000 houses annually• Largest companies build 800 houses
annually
Single-family houses
J. Lessing
• 10-15 companies dominate the market
• Produced as flat elements or volume elements
• Focus only on domestic market• Potential for export
Single-family houses
J. Lessing
Multi-family houses• In the last decade, great efforts in developing and bringing to
market new industrialized concepts for multi-family houses• Industrialized concepts for residential buildings have increased
from close to 0% to about 15% in 10 years• Wood based structures dominate
J. Lessing
Multi-family houses• All major construction companies have
developed concepts within this field• Sweden is a small market; 20.000
apartments and houses/year• Approx 10 companies active in this
development• Development cost and volume must be in
balance• Some initiatives went out of market
J. Lessing
Multi-family houses• Companies produce typically 300-800
apartments annually• Developed building systems • Extensive prefabrication (panel- or
volume-elements)• Unique, customized buildings • Extensive industry-academia –
collaboration has reinforced the development
J. Lessing
IKEA+SKANSKA: BoKlok• A product concept developed by IKEA and SKANSKA
• Aimed at defined customer segment, low, fixed prices (IKEA)
• Extensive product development and customer knowledge
• Defined house-types, limited customization
• Extremely high prefabrication in modules (85%)
J. Lessing
• Cost efficient production necessary to keep low prices
• Surveys to all customers after 2 years
• 98% would recommend the concept to a friend• Sell apartments at IKEA stores
• Expanded the market to: Sweden, Norway, Denmark, Finland, UK
IKEA+SKANSKA: BoKlok
J. Lessing
Trend #1Platforms for increased internal efficiency• Increased effectivity for the contractor/builder• Technical solutions structured in platforms• Process support: planning methods, BIM,
logistics• Mainly follow traditional building process
Total-concepts offered • Product development replace project design• Concept owner control the entire process• Complete building- and production systems• From contracting to product offers• New roles and business models Source Hvam et al (2008)
J. Lessing
Trend #2
More actors involve in IC development•Clients reclaim control over the “product” and show interest in the process•Clients develop product platforms and product strategies
•Engineering consultants develop platforms for efficient design processes (internal efficiency)•Partners with IC-companies to develop building systems together (Full-concept)
J. Lessing
The future…
• Huge potential!• We have only just started…• Customer focus is the key!
• Cross-industries learning speed up innovation
• International collaboration distribute knowledge and experience

2014 Forum
December 4, 2014
As its name implies, Intermodal Structures designs,manufactures and delivers single and multi-story, steel framebuildings (intermodally) to customers located anywhere in theworld. The buildings are earthquake and hurricane/typhoonproof and their moment frame design enables 40 feet of clearspan without requiring any columns or structural walls. Theirlong life, expandability (both horizontally and vertically),adaptability to different uses over time and relocatability futureproofs our buildings.
• Long Life• Relocatable• Flexible• Sustainable• Intelligent• Intermodally Transportable• Highly Scaleable• Outsource Strategy• Minimal “Set” Duration
