  3. An analysis of the Building Information Modelling process, and Current issues with European methods of measurement Matthew Edwards – Director : Elevations-BIM

  4. >>>What is Building Information Modelling (BIM) – Differing Views ? UK Construction Project Information Committee: “Building Information Modelling is digital representation of physical and functional characteristics of a facility creating a shared knowledge resource for information about it forming a reliable basis for decisions during its life cycle, from earliest conception to demolition.” - USA: Associated General Contractors : "an object-oriented building development tool that utilizes 5-D modeling concepts, information technology and software interoperability to design, construct and operate a building project, as well as communicate its details."[

  5. What type of projects can BIM be used in ? • ………Practically anything that can be designed in 3D !! • 3D Architectural Design • 3D Civil / Structural Design • 3D M & E Design • 3D O & M Design / Commissioning / Long Term Preventative Maintenance • Construction Projects include : • Commercial Projects – Hotels / Offices / Supermarkets / Warehouses • Residential Projects– Multi-Storey Buildings / Apartments • Educational Projects – Schools & Universities • Government & Local Authority Projects – Civic Offices • Major Capital Construction Projects – Regeneration Schemes • Civil Engineering Projects include : • Major Structures – Tunnels / Bridges / Basements • Renewable Energy Schemes – Wind Farms • Power Stations – Hydro and CHP • Water Treatment & Sewerage Treatment Plants • Linear Projects – Rail / Motorways • Major Capital Civil Engineering Projects • Rail Projects – RPA & Irish Rail Projects

  6. >>>How many dimensions are there in Building Information Model (BIM) ? 3D –3D Design 4D – Linking 3D objects to Gantt chart activities 5D – 4D + Resources / Costs ( Built into activities) 6D – Sustainability (and Robustness of 3d objects) 7D – Facilities and Asset management 8D – Post Occupancy 9D…TBC

  7. >>>What is a Building Information Model (BIM) ? What is the Lifetime of a typical BIM model ? Answer : A BIM model has a Life time in digital format, like a building has a lifetime in reality, from conception to demolition. 40 years 3 years 3D >>6D 37 years IPD Stage Facilities Management >>7D

  8. >>>What is BIM Integrated Project Delivery (IPD) Integrated Project Delivery (abbreviated IPD), is a collaborative alliance of people, systems, business structures and practices into a process that harnesses the talents and insights of all participants to optimize project results, increase value to the owner, reduce waste, and maximize efficiency through all phases of design, fabrication, and construction. The IPD stage of a project is only around 3-4 years of a project life where it is built. This is the Design / Procurement / Construction and Commissioning stage. The remainder lifetime of a project is the facilities / asset management stage which is the seventh dimension (7D). Current forms of contract do not take account of this. Answer : Multi Party Form of Contract

  9. >>>So, What is a 3D object ? A column has : Quantities Dimensions Loadings info & Calculations Specification A 3d object has : Quantities Dimensions Loadings info & Calculations Specification COSTS !!!

  10. >>>What is a 3D object ? So, a BIM model can be made up of multiple 3d objects, to create a 3d model

  11. >>>How can we link 3d objects to create a 4d timeline.? So, a BIM model can be made up of multiple 3d objects, to create a 3d model , these can be interlinked with activities from a Gantt chart and costs for permanent and consumable resources can be applied.

  12. >>>What is constructability ? Wikipedia : Constructability (or buildability) is a project management technique to review construction processes from start to finish during pre-construction phase. It is to identify obstacles before a project is actually built to reduce or prevent error, delays, and cost overrun. >>>Why is it so important in BIM ? Constructability is important in 3d/4d modelling as models need to be created and built as per construction methods and knowledge on-site in line with realistic time and cost constraints. Historically, Planners, schedulers and Project controllers provide constructability within their Gantt charts when they construct within their minds logically with design and methods..

  13. >>>What is constructability ? Wikipedia : Constructability (or buildability) is a project management technique to review construction processes from start to finish during pre-construction phase. It is to identify obstacles before a project is actually built to reduce or prevent error, delays, and cost overrun. >>>Again ……..Why is it so important ? Unfortunately …Designers produce designs that are NOT constructible & why ? Because they are designers and not constructors ! This is an issue …..

  14. >>>What is constructability ? Take for example – a RC floor slab (50mx50m) …. The pour is 3000m3 of concrete with a depth of 1.200m…..It was priced at tender stage by the contractor with a BOQ undertaken by a PQS using 2d drawings. The architect created the design and the structural engineer designed the slab within these parameters incl. rebar and concrete mix..The PQS measured it and produced a BOQ for the tender..

  15. >>>What is constructability ? The pour is 3000m3 of concrete with a depth of 1.200m….. Is it constructible ? No ! How can it be made constructible ? By allowing input from the constructor and planning the sequence of pours in line programme / schedule & the contractors budget. The 3d object is divided into 4 pours of 750m3 each – It is now constructible.

  16. >>>…BIM can be used to produce this accurate 5D BIM cost management data derived from the BIM model at preconstruction / construction stage… Constructible 3D Objects

  17. >>>….Examples of 4D/5D BIM scheduling with BIM Cost Management at Live contract stages… Schedule / Gantt Planned Model Actual Model 5D Resources 5D Cash Flow

  18. ….Advantages and Disadvantages of BIM • Disadvantages: • Current Contracts • Behavioural Risks • Technology Reliance • Model Ownership • BOQ ISSUES Advantages: • Visualisation • Collision and Defects Correction • Time and Cost savings • Take off and estimating • Communication and Collaboration • Scheduling and Project Management • Sound and Light Analysis • Sustainability • Off-site Construction • Field verification and guided layout • Constructability and Safety plan, Risk and Hazard Identification • Minimisation of Waste • Life cycle Data

  27. Time and cost benefits of BIM • A study done by Stanford University Centre for Integrated Facilities Engineering (CIFE) figures based on 32 major projects using BIM indicates benefits such as (CIFE, 2007): • Up to 40% elimination of unbudgeted change. • Cost estimation accuracy within 3%. • Up to 80% reduction in time taken to generate a cost estimate. • A savings of up to 10% of the contract value through clash detections. • Up to 7% reduction in project time. (Azhar S. et al.(2009))
