3. Moving from the traditional methods into a BIM based quantity takeoff and estimating - what we have learned during the last 10 years?

4. Adopting Emerging Technologies • BIM is close to the mainstream market • What are the barriers to reach it? • People, processes and tools

5. User Specific Issues

6. Hardware & Operating System • There are system requirements... • processor and memory • video card and screen resolution • Not a big problem today, but... • models are getting more complicated :-(

7. Unrealistic Expectations Why this does not happen automatically? Many people seem to want a single button • is it realistic? • what would it mean?

8. Frequency • If you do BIM based takeoff once in a year, you forget how to do it

9. Solution? • people with deep understanding of BIM • necessary hardware and software • constantly working in BIM projects Contractors are starting to build in-house competence centers for BIM Developers are hiring specialized BIM consultants to manage the process Future?

10. Industry Wide Issues

11. Process Instead of the Tool • Modeling requirements • what needs to be modeled? • what objects (e.g. wall) should be used? • what identification information is needed? • Delivery process for the models • what is the model contents in each design phase? • what file format(s) is used? Suitable for purpose X Usable for purpose X

12. 2D Ecosystem • Measurement rules and cost databases are typically optimized for 2D and humans • difficult to use with 3D geometry • difficult to implement in a software Wall has a ... ... net area! x Height of the wall x Height of the windows

13. Solution? • developers, architects and contractors • development will take some time! Various parties are developing the new process and guidelines for it Existing measurement rules and cost databases will be a big problem • requires changes also from suppliers • e.g. Finnish precast concrete industry

14. Benefits of BIM?

15. Measuring the Benefits • Benefits have been difficult to measure • What about saving time? • Less takeoff  more estimating = same time Better information for decision making Support of process innovation Substitution of human labour New value propositions for the clients!

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

18. >>>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."[

19. 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

20. >>>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

21. >>>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

22. >>>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

23. >>>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 !!!

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

25. >>>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.

26. >>>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..

27. >>>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 …..

28. >>>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..

29. >>>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.

30. >>>…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

31. >>>….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

32. ….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
