  3. BuildingCost Information Service of Royal Institution of Chartered Surveyors Online database of elemental cost analyses for buildings • 17,000 buildings • Data for: • Business case/early cost advice • Budget setting • Benchmarking • Standard elemental data structure

  4. Cost analyses BCIS Standard Form of Cost Analysis • ‘Purpose of cost analysis is to provide data that allows comparisons to be made between the costs of achieving various building functions in a project with those of achieving equivalent functions in other projects.’

  5. Element Element: A major physical part of a building that fulfils a specific function or functions irrespective of its design, specification or construction.’

  6. Elements used for other things than costs eg performance specification

  7. Objective Project with UK Defence Infrastructure Organisation (DIO) ‘To collate cost data on civil engineering schemes in a consistent format that can be used for benchmarking and future cost estimates’

  8. Uniclass Uniclass UK United Classification for the Construction Industry: 1997: Table E Construction entities Table H Elements for civil engineering works

  9. ISO 12006-2 ISO 12006-2 Building Construction-Organisation of information about construction works Part2: Framework for classification of information Proposes tables for: • Entity (by Form) • Elements

  10. Entities: a building

  11. Entities Entities = structures with common object functions Entity: an independent construction of significant scale classified by its physical form/basic function (Uniclass) Entities: Independent material construction result of significant scale serving at least one user activity or function. The basic unit of the built environment, eg building, bridge, road (sic), dam(?), tower, sewer (sic), museum (sic), sports field (sic), sewage settlement tank (sic). (ISO 12006-2) Therefore we are looking for Entities i.e. civil engineering structures with common ‘Object Functions’ as these will, hopefully, have common elements.

  12. Entities Pavements Railways (trackways) Platforms, quays, piers and jetties Retaining structure Dividing structures Support structures (masts and towers) Pipelines Open conduits Bridges (spanning structures) Tunnels …

  13. Projects • A project is a grouping of entities

  14. Project: Building and external works Building Cable Pipe Road Hard landscape Soft landscape

  15. Project: Road and external works Building Road Cable Pipe Hard landscape Soft landscape

  16. Survey • Web survey of RICS members worldwide (35 responses) • Existing contacts US and Canada • Existing data collected • Web search

  17. Survey 47 data structures 30 cover civil engineering (one or more entity) Four main purposes • Specification • Classification • Measurement and procurement • Cost analysis Three basic types • Work results • Elements • Mixed and ‘Parts’

  18. Survey Summary of classification survey.xls

  19. Draft Civils SFCA outline data structure 24-1-11.doc

  20. 3.2 Entity definitions Buildings Definition: Enclosed usable floor space Includes: Buildings Primary functional unit: Gross internal floor area (m2) Pavements Definition: Unenclosed usable surfaces Includes: Roads, runways, hard landscaping etc Primary functional unit: Surface area fulfilling primary function (m2)
