The Issue of Conversation & Communication

Transcription

1 The Issue of Conversation & Communication Keep It Simple Not Simplistic No repeatable and verifiable method for requesting (RFI) or exchanging information supporting BIM based collaboration and building lifecycle management

2 Where We Are Going Information systems are developed around the available forms of communication We are evolving from paper-centric to an info-centric process from conversation to communication from outputs to outcomes from ad-hoc to standardized CAD to BIM Text to Database to Portal Workflows Unstructured to Structured Data Knowledgable Workers to Knowledge Management Stovepiped Disciplines to Collaborative Teams

3 Information Value-Chain Developing the Information Value Chain IDM Workflow Processes for an Integrated Team Business Logic IDM Part of the NBIMS IDM s inform software companies of the processes to support BIM Applications Planning Architecture Engineering Analysis BIM applications Content Incorporating NA Data Standards Including OMNI-Class, Uniformat, International Building Code OSCRE IFC/OGC IFC s/ogc Web-Services are the machine interpretable exchange mechanism supporting IFC interoperable applications Estimating Construction Facilities Management

4 Getting to Best Practices Expedia & Self Documenting Processes Process A Process B Today Paper and Ad-Hoc Conversation Based Design Process A Process B BIM Technology & Process Based Design Allows move to Value-Add activity (expedia decision process)

5 Data Sets Lifecycle Development Knowledge databases -Best practise knowledge -Own practice Laws and regulations -Building regulations -Building specifications CAD software -Drawings, calculations -Architect, engineer, IDM VRML -Visualisation, 3D models Briefing -Functional req. -Estimates -Conditions -Requirements Demolition, refurbishment -Rebuild -Demolition -Restoration IFC + IFD product model Simulations -Comfort -Ventilation, heating -Life cycle cost -Light, sound -Insulation -Fire, usage -Environment -Life time predictions Facility management -Letting, sale, operations -Maintenance -Guaranties Construction management -Scheduling -Logistics, 4D Specifications -Specification sheets -Classification standards -Estimates, accounting Procurement -Product databases -Price databases

10 Context RFI- Business Case Development 1 2 Business Case Development WHO (is requesting) Actor requesting information to support a process or decision (Authoritative Reference OMNI CLASS Table 33 & 34) WHY (project/process use or benefit) Why is this information important for a project activity (Authoritative Reference OMNI CLASS- Table 32) Omniclass Table 33 Disciplines/expertise WHO/To WHOM Data Sets to Support Business Case Omniclass Table 34 Organizational Roles/responsibility WHO/To WHOM 3 WHEN (stage in project) (Authoritative Reference OMNI-CLASS-Table 31) Table 31 is tied to IFC Phases (Project Lifecycle) Omniclass Table 32 Services Activities/WHY Omniclass Table 31 Phases WHEN 4 5 Dataset in BIM that supports the request and benefit) Because BIM use aggregates information several tables support this activity. Authoritative Reference OMNI-CLASS Tables 11, 12,14, 21, 23, 41, 49 To WHOM Group/Actor that provides/fullfills the information need OMNI-Class Omniclass Table 35 Tools/supporting HOW Omniclass Table 22 Work Results/quality (Legacy MasterFormat) HOW 6 HOW Tools/formats/results Table 35 & 22 Omniclass Table 36 Information INPUT & OUTCOME 7 INPUTS & OUTCOME Information, Product or Service Delivered Omniclass 36 Architect Engineer

11 Tools to Data to Purpose AIA-TAP focus on three inevitable technologies: BIM, collaboration, and interoperability BIM requires a structured understanding of objects International Definition IfcStair Definition from ISO :1989: Construction comprising a succession of horizontal stages (steps or landings) that make it possible to pass on foot to other levels. Definition from IAI: A vertical passageway allowing occupants to walk (step) from one floor level to another floor level at a different elevation. It may include a landing as an intermediate floor slab.
