Information Requirements


Information has to be produced for a reason• It is a valuable commodity in its own right• It takes time and costs money to generate

Information is for a purpose


Information requirements specify what is wanted• Many different information

receivers• Business, asset management

and project delivery perspectives

• Translation/re-statement from strategic to high-level to detailed

• Line of sight from each detailed requirement to a higher-level purpose


Summary of information requirements

IR Scope When (examples) Who (examples) How

OIR Strategic organisation-wide need for information

Board meetings, statutory returns, strategic reviews

Finance, compliance, CSR, production, operations

Stakeholder interviews, workshops

AIR Asset-level (building, road, pipeline, etc)

Annual reports, strategic reviews, major trigger events

Asset managers, operations directors

Corporate schedule (tailored per asset)

PIR Project-level (new-build, refurbishment, extension)

Key project decision points (governance gateways)

Project sponsors, project managers, investment directors

Corporate schedule (tailored per project)

EIR (operational and delivery)

Contractual obligations within each project or asset appointment

Trigger events and project decision points

Project and asset managers, package managers

Schedule of what information, how much detail, delivery milestones


Reduce embodied and operational CO2 by 40%by 2030

Example cascades of information requirements

OIR

EIR(Operational)

PIR

EIR(Delivery)

Annual asset operation CO2 reportReplacement equipment selected for CO2 reduction

Embodied CO2 analysis showing reductions for new projects

Annual CO2 report by in-house sustainability teamEach equipment requisition to include CO2 assessment

Design consultants and contractors to include CO2 data on all approval submissions

Support local workforce

80% of sub-contract value with firms within 30 mile radius of site

Contractor to provide s/c location report at milestones 4, 5, 6


EIRs – the what and the when

Supported by asset/project-wide information resources

Exchange Information Requirements- information requirements- level of information need

- acceptance criteria, supporting information- date(s) for requirement to be met

OIR, AIR, PIR

Information delivery

milestones

Information standard

Information production methods

and procedures

Reference information and shared resources

...


Structured and unstructured information – detail can be specified independently via the level of information need

Geometrical information

E.g. 3-d model with embedded object

data

DocumentationE.g. scanned

certificate, site photos, reports

Alphanumerical informationE.g. COBie

spreadsheet, sensor data

stream


Timing of information exchanges relative to project stages or trigger event completion


Development of information requirements has to be led by the project client or the asset owner/operator (appointing party in ISO 19650)

Each information requirement needs to be in enough detail so that the person setting it can judge whether the information supplied in return is acceptable

It is vital to avoid gaps and duplications between sets of exchange information requirements, which will introduce risk and cost to the project/asset management and the lead appointed parties

KEEP IN MIND


Level of Information Need is NOT the same of Level of Definition

You cannot define the Level of Information Need without defining the Pre-requisites first, especially the Purpose

You should NOT abbreviate «Level of Information Need»

Level of Information Need framework includes: Geometrical Information, Alphanumerical Information and Documentationand concepts and principleas are defined in BS EN 17412-1
