10. WHAT IS QUALITY?
“Ultimately, quality is an outcome – a characteristic of a product
or service provided to a customer, and the hallmark of an
organisation which has satisfied all of its stakeholders”

Brief introduction to NBS, who we are etc.
What is quality?
BIM and quality – are these two things mutually exclusive or is there an overlap
Demonstration of the benefits of getting the quality of your BIM objects right
And if that works I’ll hang around for some questions, and if it doesn’t you’ll see me running out the door.
NBS is part of a large organisation that has been serving the construction industry for over 40 years.
NBS is part of RIBA Enterprises and we are wholly owned by the RIBA which is a registered charity.
We are a knowledge business.
We connect people to information, so that they have the knowledge they need to make the right project decisions.
We employ over 250 staff
NBS serves 20,000 customers
Practices 5000.
97 out of the top 100 architects use NBS.
over 10,000 manufacturers listed in our directories and 1,000 plus manufacturers taking specialist product such as NBS Plus – which is a tool to embed your product details into specifications.
Official publisher of the building regulations approved documents
We are the uk provider of British standards and other construction documents through our online portal the Construction Information Service.
£36billion each year spent by Government on Centrally Funded Public buildings.
Provides 3 million jobs
Millions lost through poor integration and not making use of lesson learned.
30% of the construction process is rework
60% of the labour effort is wasted
10% loss is due to wasted materials
So in terms of quality – it doesn't look like things are going right. In terms of value for money – this doesn't look particularly good value.
This is what the government is aiming for by 2025.
This is where we are heading.
This is from their Industrial Strategy published last year.
Early BIM projects have achieved saving of around 20% during the construction phase to they are targeting 33% savings over the life of the building.
The government BIM mandate is a stepping stone to greater things.
It’s a simple approach to collect all construction info digitally.
Asking for the information about a building in digital form by 2016 is not really a big ask.
The objective of the Construction Strategy 2011 is to accelerate the adoption of BIM throughout the UK construction supply chain to achieve significant improvements in cost, value and carbon performance through the use of open sharable asset information .
Industry operates in different silos.
Without a clear understanding of the requirements or demands of each party the quality of what is delivered or provided is hard to assess or deliver.
With BIM those silo are disappearing.
With information in a common data environment and data that is standardised, we can collect the benefits of a more integrated and collaborative approach.
Sharing information is becoming easier via the cloud and with a consistent information structure – more use and insight can be derived from the data.
Learning from how our buildings are used and feeding that back into the briefing process for other developments or refurbishment is what we need in order to derive more value from our built assets.
Ok,
So lets consider quality for a second. What is it?
What does it really mean.
Here’s how ISO 9000 defines quality.
The ISO 9000 series covers quality management.
I also looked at what the Chartered Quality Institute said about quality.
And finally, the health foundation define quality in this way.
Interestingly in this example quality is clearly something that is about being exceptional or achieving excellence.
In other sectors quality may be concerned with achieving minimum standards.
If quality isn’t taken seriously things like this can happen.
Clearly in this example there has been a number of quality failures along the project timeline
Maybe the design certainly the installation and certainly the checking.
I’m hoping this is simply a Photoshop spoof.
Here’s my take on quality.
Now I’ve used object in this sentence not specifically in reference to BIM objects, it could really mean any object or experience.
So if quality is a measure of how something fulfils it’s purpose then how do you judge quality?
The quality of an object depends upon a set of requirements that align with a given purpose or need, plus the object’s inherent characteristics;
with quality being the measure of how well the characteristics comply with the requirements.
This is how trip advisor defines quality.
Measuring quality can obviously be complex so schemes exist that help to provide a quick and easy method identfiying quality from a consumers perspective.
Here are some of the standards that relate to BIM and BIM objects
PAS 1192-2
BS 8541-1 – Library objects
BS 1192-4 – COBIE
And the newest of them all the NBS BIM Toolkit – which offers free to use standard object definitions for all disciplines.
The help and leadership provided by the government’s BIM Task Group has, without doubt, been an extremely successful approach.
Other countries are in awe of how far we’ve come in a relatively short time. The release of freely available, accessible-to-all standards has given the UK a big advantage over its overseas competitors.
Standards are vital to all industries…. they
Reduce time
Improve quality
Permit compatibility and integration
Improve value for money
Enable trade
and their mere existence offers the purchaser a means of accepting or rejecting goods, on the basis of whether or not they comply with the standard.
Looking a bit more closely at bim objects and the aspect of quality now.
There has been lots of work done by many to create free to use objects that can be downloaded from the web.
Here’s some of the more fun objects I’ve seen.
However, whilst the existence of lots of free to use objects is good for designers – the severe lack of consistency and standardisation is a real and growing problem.
When the National BIM Library was launched in 2012 we set a standard for our own use when creating objects for our customers, that standard has since evolved and during the various industry focus groups we’ve held it become very apparent that the UK needs a common standard as many who are creating their own objects want to be able to create objects that will be compatible with those found in the National BIM Library.
So we decided to do some further research and create and publish a BIM object standard.
We reviewed what was available already – there’s lots out there covering varying aspects and we wanted where possible to support the standards already in place and we also wanted to focus on creating a standard that was achievable and something that very much reflects the requirements of level 2 BIM
with support for open standards
and multiple platforms
So after lots of head scratching and deliberation we published the NBS BIM Object Standard last September.
It has been download by those outside of NBS more than 5000 times.
Our approach was to create very clear rules that are easy to understand and apply.
We worked hard to provide support for all of the main platforms, and we are also very grateful for those that helped us create the standard. Many help to review the document and shape what it covered.
Objects need an identify – so we created various rules that build upon industry convention for file naming and object naming standards.
We worked hard to create standardised terms which has been further expanded by the NBS BIM Toolkit which covers over 5000 object definitions.
With a consistent structure and standard use of terminology – this helps objects be compared and integrated within a project BIM.
We defined what we believe to be the right level of detail for library BIM objects.
Schematic level of detail, coordination view level of detail etc.
Not too much, but something that reflects manufacturers product characteristics.
We looked beyond the physical dimensions and also looked at how objects can behave and support the early stage design process
So the benefits of any standard and in this case the NBS BIM Object Standard can be seen in the ease of use of the objects in the bim environment.
Assurance - This standard fills a gap and sets a quality standard which will help clients procure buildings. Project Managers and Clients using the NBS BIM Object Standard can benefit as you can be confident that the quality of BIM objects within your project models is suitable and to a known standard.
Efficiency - Designers are creating objects themselves as there are not enough manufacturers objects in the market place. Using the standard will bring efficiency to your processes and lead to better designers and better buildings. Designers creating their own objects for practice and project-specific purposes can now do so to a common standard enabling greater collaboration, efficiency and more meaningful information exchange.
Quality - Manufacturers you really have a job to do. You have the challenge of creating objects and making them available at the right time in the right place all by 2016. This standard gives manufacturers wanting to create objects themselves a clear benchmark. It’s something that provides knowledge and enables manufacturers to attain and comply.
Compatibility – Just like we have with batteries, nuts and bolts, usb connectors, plug sockets, and in the not too distant future mobile phone chargers, standardisation brings compatibility. BIM objects need to work with each other
The standard can be found and accessed for free via the National BIM Library website.
The BIM Toolkit is an online tool. It is free to use.
The toolkit is also a free online model viewer
As well as being able to view a model, you can navigate the model via the deliverables
You can also check the provision of information against the demand side requirements
The screenshot shows a simple report the indicates what information is missing
Slide about validation of data.

Graphisoft addon – developed to make the creation of objects in ArchiCAD to the NBS BIM Object Standard easier.
More and more organisations are using the BIM object standard and coupled with the NBS BIM toolkit can really make a difference.
Next steps your feedback – how can we take the standard forward.
How are you using it in your organisation – we’d love to hear from you.
BIM in the UK has been government led and is very much technology driven
Technology is driving change across all industries. This is affecting your business now.
BIM is about creating a digital model that everyone can use and understand.
This will make buildings work better, we’ll get better value buildings, and you can grow your business and thrive….. BIM is an enabler.
The construction industry needs to be digital.
