How to traditionally describe construction data PLQ: How Many Legs Do I Have?

LOD

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.

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

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”

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

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

Assessment and need

Figure taken from PAS1192-2:2013 – Copyright Mervyn Richards Assessment and need

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

A collection of projects

Information at a project level

Information at a stage level

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

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

Template tasks can be modified, removed and added to

These projects can be refined and reused on future projects

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

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

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

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

Procurement

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

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

Production

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

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

Level of detail guidance can be defined for each deliverable

Level of information guidance can be defined for each deliverable

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

At concept stage – the operations phase should be considered

At the technical design stage more geometric detail is required

The level of information grows through the bandings too

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

The definitions library covers infrastructure in addition to buildings

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

Rules of measurement f rom RICS NRM1

Benchmark costs from RICS BCIS

Filter by Uniclass 2015 classification tables

At an early stage space requirements may be specified

Classification – Uniclass 2015

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