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

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.

15. The Level-2 BIM package
How will the BIM Toolkit benefit those working within the level-2 BIM process?

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
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
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
