My presentation
• Residential construction in NZ
• Impact of IT on improving productivity
• Challenges of implementing BIM into SMEs
• See what we have done to overcome these
This is our Story

Residential Construction in NZ
![Page 4: BIM SHOW LIVE 14 - BIM for residential](https://reader037.vdocument.in/reader037/viewer/2022110109/554a3f2db4c9055a408b4d61/html5/thumbnails/4.jpg)
![Page 5: BIM SHOW LIVE 14 - BIM for residential](https://reader037.vdocument.in/reader037/viewer/2022110109/554a3f2db4c9055a408b4d61/html5/thumbnails/5.jpg)
![Page 6: BIM SHOW LIVE 14 - BIM for residential](https://reader037.vdocument.in/reader037/viewer/2022110109/554a3f2db4c9055a408b4d61/html5/thumbnails/6.jpg)
Companies that build new houses
NZ doesn’t have a large Local Authority or Housing Association sector
![Page 7: BIM SHOW LIVE 14 - BIM for residential](https://reader037.vdocument.in/reader037/viewer/2022110109/554a3f2db4c9055a408b4d61/html5/thumbnails/7.jpg)
So the typical house builder is small• So tend to lack sound internal processes
• Have a low adoption of IT
• But represent bigger potential for gains that bigger companies (who do have systems)
![Page 8: BIM SHOW LIVE 14 - BIM for residential](https://reader037.vdocument.in/reader037/viewer/2022110109/554a3f2db4c9055a408b4d61/html5/thumbnails/8.jpg)
Construction has a big impact on the economy
• Is about 10% of NZ GDP
• So a 10% productivity improvement adds 1% to GDP
• The government has set a target of a 20% productivity improvement
by 2020

And productivity isn’t good
What does this mean?
Lower wages – employers can’t afford to pay moreLower profits – a struggle to make a buckExpensive houses – when compared to other goodsLess innovation – business focused on survival don’t invest

There is a connection between ICT uptake and productivity
• Chris Hector, researcher in economics at Waikato Management School“but it has a lag in it”
• Grant Florence, CEO Certified Builders

Why IT collaboration works in manufacturing
• Standardisation. Houses are generally different• Long production runs and long term supply. One off• Long term relationships with investment in communication. Transient
![Page 12: BIM SHOW LIVE 14 - BIM for residential](https://reader037.vdocument.in/reader037/viewer/2022110109/554a3f2db4c9055a408b4d61/html5/thumbnails/12.jpg)
BIM capable authoring tools are widely used for design
Masterspec National BIM Survey 2013

With BIM, typically we are talking large commercial projects
• Projects are large / long enough to warrant communication investment
• Teams dedicated to a single project
• PAS1192, BIM Handbook
• BIM is becoming more common
• Still a long way from universal

Designer
• Often builder isn’t known at design phase• Builders deal with a range of designers• Often builders regularly use the same trades• But those trades deal with multiple builders and projects in parallel• No one invests much in communication
![Page 15: BIM SHOW LIVE 14 - BIM for residential](https://reader037.vdocument.in/reader037/viewer/2022110109/554a3f2db4c9055a408b4d61/html5/thumbnails/15.jpg)
The industry is still fundamentally paper based
![Page 16: BIM SHOW LIVE 14 - BIM for residential](https://reader037.vdocument.in/reader037/viewer/2022110109/554a3f2db4c9055a408b4d61/html5/thumbnails/16.jpg)
The good thing in NZ is over 50% of NZ houses are designed using BIM
capable tools
![Page 17: BIM SHOW LIVE 14 - BIM for residential](https://reader037.vdocument.in/reader037/viewer/2022110109/554a3f2db4c9055a408b4d61/html5/thumbnails/17.jpg)
Our vision is to unlock these models
• Transparent information
• Construction is a complex process
• We can’t make it simpler but we can hide the complexity from the user
• Very much the BIM story everyone is talking
![Page 18: BIM SHOW LIVE 14 - BIM for residential](https://reader037.vdocument.in/reader037/viewer/2022110109/554a3f2db4c9055a408b4d61/html5/thumbnails/18.jpg)
BIM = GST (or VAT)
![Page 19: BIM SHOW LIVE 14 - BIM for residential](https://reader037.vdocument.in/reader037/viewer/2022110109/554a3f2db4c9055a408b4d61/html5/thumbnails/19.jpg)
There are challenges to doing this• Multiple data sources• IP and liability issues• Varying construction methods• Lack of understanding of true construction costs
![Page 20: BIM SHOW LIVE 14 - BIM for residential](https://reader037.vdocument.in/reader037/viewer/2022110109/554a3f2db4c9055a408b4d61/html5/thumbnails/20.jpg)
2D drawings are still the standard• Main communication mode is still paper or electronic
paper (PDF)
• 3D CAD BIM models don’t contain all of the required information
• It isn’t practical ot model everything
![Page 21: BIM SHOW LIVE 14 - BIM for residential](https://reader037.vdocument.in/reader037/viewer/2022110109/554a3f2db4c9055a408b4d61/html5/thumbnails/21.jpg)
The designers BIM isn’t always right• Using the designers BIM model assumes that it is right• Reality is, it can’t be• 2D communication provides a process break so allows user
to resolve specific details
![Page 22: BIM SHOW LIVE 14 - BIM for residential](https://reader037.vdocument.in/reader037/viewer/2022110109/554a3f2db4c9055a408b4d61/html5/thumbnails/22.jpg)
Our competition is a spreadsheet and highlighter• Drawings
• Highlighter pen• Spreadsheet
• Human error prone• Time consuming• Skilled resource required• Difficult to scale• 2D based• Spreadsheet Guru dependent / IP Issues
Typical errors• Translation to spreadsheet• Missed items• Scaling• Typos / Overtyping formulas
![Page 23: BIM SHOW LIVE 14 - BIM for residential](https://reader037.vdocument.in/reader037/viewer/2022110109/554a3f2db4c9055a408b4d61/html5/thumbnails/23.jpg)
So all we need to do is
• Handle BIM from variable sources and of variable quality
• Take 2D and paper
• Have a system that largely works out “of the box”
• Is easy to use
• Easy to support
• Doesn’t cost much
![Page 24: BIM SHOW LIVE 14 - BIM for residential](https://reader037.vdocument.in/reader037/viewer/2022110109/554a3f2db4c9055a408b4d61/html5/thumbnails/24.jpg)

Recipes are a common approach
• Stores a recipe or classification code on BIM element
• Recipe contains breakdown of materials and labour
• Any change in element characteristics needs a new recipe
• Works well when designer and builder agree codes and materials don’t
change
• Therefore not so good
with residential
![Page 27: BIM SHOW LIVE 14 - BIM for residential](https://reader037.vdocument.in/reader037/viewer/2022110109/554a3f2db4c9055a408b4d61/html5/thumbnails/27.jpg)
Our solution is to use a parametric methodology
• Elements have properties and property sets
• Reuse as many decisions from the 3D CAD BIM model as possible
• Use the properties to make decisions about the element
• Working with buildingSmart Australasia to define a property
structure for residential elements
![Page 28: BIM SHOW LIVE 14 - BIM for residential](https://reader037.vdocument.in/reader037/viewer/2022110109/554a3f2db4c9055a408b4d61/html5/thumbnails/28.jpg)
Allows for activity based costing• Using square meter or linear metre labour rates are only an average
• Activity based costing looks at what attributes drive the tasks and labour times
• Much more sensitive to design differences
![Page 29: BIM SHOW LIVE 14 - BIM for residential](https://reader037.vdocument.in/reader037/viewer/2022110109/554a3f2db4c9055a408b4d61/html5/thumbnails/29.jpg)
Intel New Unit of Computing
• SME builders tend lack robust and repeatable IT processes
• System as an appliance
• Couriered with software pre-installed
• Remote help software loaded
• Included in software price
![Page 30: BIM SHOW LIVE 14 - BIM for residential](https://reader037.vdocument.in/reader037/viewer/2022110109/554a3f2db4c9055a408b4d61/html5/thumbnails/30.jpg)
Go to market strategy
• Cost per won project
• Regional support providers
• Offer a range of services giving customers the option of having
take-off or other tasks done for them
![Page 31: BIM SHOW LIVE 14 - BIM for residential](https://reader037.vdocument.in/reader037/viewer/2022110109/554a3f2db4c9055a408b4d61/html5/thumbnails/31.jpg)
Customer feedback
• Paint is still drying on the residential BIM product
• Feedback very positive
• One early adopter is quoting savings of $2,000 per house
• A manufacturing customer reduced waste from 12% to 5%
• Council has increased inspections by 12%
