    1. Cost Analysis of Civil Engineering Projects IFC-Infra meeting, Paris, 8th July 2011 Presented by: Joe Martin, BCIS Executive Director

    2. Note: this slide has been stolen from Christophe Castaing (EGIS) and Pierre Benning (Bouygues Travaux Publics)

    3. Building Cost 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

    5. 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.’

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

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

    8. 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’

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

    11. 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

    12. Entities: a building

    13. 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.

    14. 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 …

    15. Projects A project is a grouping of entities

    16. Project: Building and external works Building

    17. Project: Road and external works Building

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

    19. 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’

    20. Survey Summary of classification survey.xls

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

    23. SFCECA Bridge Elements

    24. Data model and IFC for Infrastructure Note: this slide has been stolen from Christophe Castaing (EGIS)and Pierre Benning (Bouygues Travaux Publics)
