9. The focus brought about by the requirement
of the UK Government to mandate BIM
Level 2 BIM by 2016 has necessitated clarity
as to how data is:
• Defined,
• Tested
• Effectively used by both the supply chain
and the public client
The DPOW helps support how this new
‘digital’ data is procured at ‘Level 2’
enabling clear definitions of need to the
supply chain and use full data detailed to the
client for use.

10. ENSURE EVERYONE CAN PLAY THEIR PART (OPEN DATA)
The selected supply base supplying data up
to the tier one who is responsible for its
coordination use and submission to the
employer must be employed consistently to
ensure data can be created and re-used,
rather than repeatedly re-typed.
Clearly it is incumbent on the employer to
only ask for information that is needed at
each stage of the project

11. The rate of this growth must be driven by the
amount of information needed to answer each Key
Client Question. Any more and we are incurring waste,
any less and we cannot effectively answer the
questions.
These questions are known as the ‘Plain Language’
Questions.
As the project progresses the data “Progressively Grows”

12. Key ‘anchors’ for the dPoW
Plain language questions
(PLQ’s) to inform key
client decisions
COBie Data
2D PDF’s
(Native models)
Plain

questions
(PLQ’s) to
inform key
client
decisions

13. Putting too much information into the model too
soon may restrict both the design and supply
chain options for others in the team and leads to
other forms of waste with the inherent costs
incurred by both the supplier and the client.
It also places constraints on the supply chain to
offer compliant alternative designs, offering better
asset or value performance.
DPOW = Goldilocks Principle

17. Assessment and need

18. Assessment and
need

19. Assessment and need
Overview
• Client determines their plain language questions
(determines the need)
• Client produces their employer’s information requirements
(Required information to meet the needs as defined in PLQs)
• Information requirements aligned to the project stages
• This is part of the tender documentation

20. A collection
of projects

21. Information at a
project level

22. Information at a
stage level

23. At the start of the
project the client has
not assembled their
team

24. At strategy/brief stage
it is possible to
determine information
needs

25. Template tasks can be
modified, removed and
added to

26. These projects can be
refined and reused on
future projects

27. Tasks and deliverables are
assigned to roles prior to
the team being assembled
This information may
be exported

28. Export to MS Excel for
inclusion within the EIR
document (PDF)
…and export to
IFC/COBie for digital
re-use

29. All information can exported
and manipulated either in
buildingSMART or MS Excel
format

30. At a basic level – it can easily be
inserted into an MS Word EIR

31. Procurement

32. Procurement

33. Procurement
Overview
• Bidders respond with their pre-contract BIM execution plan
• Proposed responsibility of bidders supply-chain is provided
• The client can compare these against their original information requirements
• Selection can take place

34. The proposed roles
have been assigned
The proposed
project team has
been added
Each item, at each
stage has a party
responsible
The bidder

35. Export to MS Excel for
inclusion within the
BEP document (PDF)
…and export to
IFC/COBie for digital
re-use

39. Production

40. Production
Overview
• The federated Project Information Model begins to grow
• dPOW defines the what, the when and who
• Information exchanges between supply-chain
• Information delivery to the client as agreed in EIR
• Documented classification and data structure allows for verification

41. Moving into the design phases
the team is now assembled and
the information requirements
grow

42. Level of detail guidance can be
defined for each deliverable

43. Level of information guidance can
be defined for each deliverable

44. A definitions library of over 5,000
items across all construction
disciplines will be provided

45. At concept stage – the operations
phase should be considered

46. At the technical design stage
more geometric detail is required

47. The level of information grows
through the bandings too

48. LOI-6 contains the standard
COBie properties for transfer to
the asset management systems

50. The definitions library covers
infrastructure in addition to
buildings

54. RICS were part of the core team
and have provided classification
mappings to NRM1

55. Rules of measurement
from RICS NRM1

56. Benchmark costs
from RICS BCIS

57. Filter by Uniclass 2015
classification tables

58. At an early stage space
requirements may be
specified

59. Classification – Uniclass 2015

60. Advanced search technology
is used to take the complexity
away from classification
