AGS Members' Day 2015 - Data Transfer Format and BIM Presentation

  1. 1. Jackie Bland, Geotechnics Ltd/Furgo Steve Walthall, Bechtel AGS Data Management Committee 2015
  2. 2. SYSTEMS THEORY D. I. K. U. W.
  3. 3. According to Russell Ackoff, a systems theorist and professor of organizational change, the content of the human mind can be classified into five categories: Data: symbols Information: data that are processed to be useful; provides answers to "who", "what", "where", and "when" questions Knowledge: application of data and information; answers "how" questions Understanding: appreciation of "why" Wisdom: evaluated understanding. Ackoff indicates that the first four categories relate to the past; they deal with what has been or what is known. Only the fifth category, wisdom, deals with the future because it incorporates vision and design. With wisdom, people can create the future rather than just grasp the present and past. But achieving wisdom isn't easy; people must move successively through the other categories.
  4. 4. • Data: SPT N value, Moisture content, depth to water • Information: Borehole Log, PSD graph • Knowledge: GI report • Understanding: Design Report • Wisdom: Design Application of Ackoff’s model to geotechnical engineering
  5. 5. Data, the collection, coordination, transfer use and management Information, the conversion of data to information Knowledge, Understanding and Wisdom, the publication and use of reports and designs
  6. 6. DATA, SOME BASICS Data is both singular and plural BS 8574 2.5 Geotechnical Data Facts or figures obtained from all phases of a geotechnical project, including derivations from other data , (Facts and figures might include text, numbers and formulae). BS 8574 2.6 logical data data connected by location and/or time and not the representation or the evaluation of that data Meta Data Additional information which describes the data, such as the borehole number and depth for an SPT N value.
  7. 7. THE DATA JOURNEY (1990’S)
  8. 8. THE DATA JOURNEY (2014) (Chandler 2014)
  9. 9. (After Romain Arnould 2014)
  10. 10. Data storage Data ImportData Entry validationvalidation validation Data AnalysisInformation Production Data Visualisation (Information) Data Export AGS AGS AGS AGS AGS AGS
  11. 11. Why not use spreadsheets? They are not data bases They are INFORMATION not DATA They are difficult to interrogate They contain format information which is not transferable They are not software independent They often contain errors which are not easily found, i.e. they are difficult to validate and verify BS8574 A.2.4 NOTE Use of spreadsheet files for data transfer is discouraged because they contain formatting information as well as data. Interoperability problems between spreadsheet software might be experienced

Facebook launched Matt Smith becomes 11th Dr Who EGGS Conference 2015 Government mandates BIM Do BIM Level 2 now AGS 4.1 Beta
  14. 14. DATA MANAGEMENT A new British Standard has been created by the AGS Data Management committee to formalise your data management - BS8574:2014 Code of practice for the management of geotechnical data for ground engineering projects
  15. 15. WHAT IS BS8574? Gives recommendations on the management of geotechnical data throughout the life-cycle of civil engineering and building projects at both an organizational and project level. Defines data as a concept and provides recommendations on the collection, verification, manipulation, distribution, presentation and storage of data.
  16. 16. WHY USE BS 8574? For each PROJECT • Collections of data from different sources and formats • Number of organisations processing and transferring data • Data Management and delivery needs defining and maintaining throughout as documented in the specification Improves communication between the parties involved Standard has been designed for use in a BIM project in accordance with PAS 1192
  17. 17. DATA MANAGEMENT To summarise Data Management is a combination of:- BS8574, which determines what is to be done and AGS Data, which is a tool for doing it
  19. 19. INFORMATION The use of information in the development of a project Availability and transfer of information during the life cycle of the project Access to and archiving of information.
  20. 20. INFORMATION MANAGEMENT Typical Information contained in the GIR ----- Parameters
  21. 21. INFORMATION MANAGEMENT Typical Information contained in the GIR ----- Sections
  22. 22. INFORMATION A project with the working title AGSi is developing the AGS4 “Groups” and “Headings” necessary to transfer the information contained in the GIR as data. It will do this using the concept of “Layers” These layers may be Stratigraphic Lithological Weathering Engineering Environmental Water Or any combination
  23. 23. AGS4.1 BETA The document will be issued as “AGS4.1 Beta (Draft for public consultation)” It will contain the additional groups needed to transfer the data behind the information contained in the GIR (Geotechnical Investigation Report) The Parameters are derived values (not characteristic values which are in the Design Reports) The geometry of the layers will be transferred by one of three methods: 1. The use of a simple x,y,z file 2. The use of a project specific file format as defined in the BS8574 project plan, using the existing AGS external file mechanism defined in the FILE group (FILE_FSET) 3. The use of cross sections using the structure established by British Geological Survey (BGS)
  24. 24. The new Groups LAYA Layer definitions PARA Layer parameters LAYX Layer geometry (x,y,z co-ordinates) LAYB Layer boundaries LABX Layer boundary co-ordinates (x,y co-ordinates) CSLG Cross-section lines CSLA Cross-section line alignments (x,y coordinates) CSLW Cross-section line layer geometry (w,z data) additional groups to transfer ground surface topology GRNG Ground surfaces GRNX Ground surface topography (x,y,z co-ordinates) AGS4.1 BETA
  25. 25. AGS4.1 BETA The transfer file format will have the following options: Comma Separated Value file format (CSV) as per AGS format files to date and, for the first time, an XML version The use of cross sections has also neatly provided a solution to the conundrum which has existed since AGS as first started: Trial Pit sketches
  26. 26. AGS4.1 BETA Demo of cross sections - a joint project between AGS and BGS
  28. 28. KNOWLEDGE GI report UNDERSTANDING Design Report WISDOM Design These are for the future as the transfer file format develops Perhaps the committee should be renamed THE AGS WISDOM COMMITTEE but that may be a step too far FUTURE DEVELOPMENTS FOR DATA TRANSFER
  29. 29. AGS4.1 BETA Implications for the industry to be addressed Data management in accordance with BS8574 Information Management for the next phase(s) of BIM Ownership of the Data
