The duties of a product manufacturer
• Producing and selling products– Trade– Business processes
• Supplying precision technical data– Energy performance analysis– Life-cycle cost (LCC)– Life-cycle assessment (LCA)– BIM processes
Linked data?
40% of building cost
?BIM Objects
Tons of questions
• does a BIM object add value to my customers?• for which products in my product range do I need
to have BIM objects?• how much detail will I need to specify and which
software formats do I need to support?• how do I handle different professional and
process information requirements?• will there be a return on my investment and
subsequent increase in sales?

product data templates (PDTs)

“A product data template is simply a form that contains standardised headings against which manufacturers product information is placed. There is a different template for each type of product.”
Ian Chapman, NBS https://toolkit.thenbs.com/articles/pdts
What is a PDT?
Declaration of Performance (DoP)
Environment Performance Declaration (EPD),
Strategy and approach• Specified and developed by specialists in the industry with
varying relevant backgrounds e.g. professional associations, trade association, interest groups, industry standard bodies, and specifier and product manufacturer organizations
• Common shared view in specifying product types, including properties, naming, units etc. and thus guaranteeing a common set of properties and attributes in accordance with harmonized, national and industry standards and guidelines.

aim
• a user friendly tool to assist manufacturers in supplying structured data about their products– No need to manage hundreds Excel data sheets– No new PDT
• Simplify the publication process for publishing product data towards prospective customers
How
• Use the appropriate web technologies, • Use agreed PDTs, • Use intuitive interfaces (for manufacturers:
Excel)

Conclusion
Gains1. Semantic search with indexes at a much higher detail and property
level2. Facilitating innovative business ventures in linking various construction
data with manufactured product data, 3. suppliers and product distributers’ access to detailed product and
business data e.g. packaging and shipping, 4. supporting BIM object development with external detailed product
data through links to the actual product data by their unique web URI or class of products by classification code,
5. extending the product data by linking to company specific and market data (e.g. suppliers and identifying location, regions, countries where the product is eligible for shipment etc.),
6. making the product data part of the global web of data.
Future work• Synchronization of existing product catalogues with new
versions of PDTs.• The development of a more consistent method to structure
and naming property sets in the properties table is pending. • align with SPie and NBS PDTs • investigate the possibility of using the property classification
table in the OmniclassTM system as part of the properties ontology.
• Formal definitions of enumerations for enumerated properties need to be considered
• support for DoP and EDP publication.
