- 3. Presentation Parts: • A: Comparison of BIM QS Softwares • B: Comparison of BIM, CAD, and Manual Taking-Off
- 4. Part A COMPARISON OF BIM QS SOFTWARES
- 5. BIM QS Softwares • Glodon CubiCost • Exactal CostX • BuildSoft Cubit • Vico Software
- 7. Introduction • Based in China and it is one of the leading Chinese Architecture, Engineering and Construction (AEC) IT companies. CUBIC COST+
- 8. Functions Quick modelling and BIM-based quantity takeoff Professional, accurate and easy to check
- 9. Functions Various quantity reports Teamwork high efficency
- 10. Limitations Cost - The price to own a Cubicost license is very expensive and not many firms, especially smaller firms can afford it. Alternatively, softwares such as CostX and Buildsoft is more affordable but having less functions as compared to Cubicost. Newly introduced in the industry - Still not a completely stable product with its constant updates and having certain flaws in their products’ functionality. - Requires workshops by trainers to teach new users to use their products.
- 11. CostX by Exactal
- 12. Introduction CostX was released by Exactal in July, 2004 It can be used among quantity surveying, construction, development, subcontracting and more.
- 13. Products CostX CostX 2D CostX TakeOff CostX TakeOff 2D CostXL CostX Viewer
- 14. Function Ability to support various type of files and 3D model or BIM
- 15. Function 3D viewing navigation system
- 16. Function Paperless estimating Auto-revisioning
- 19. Limitation Pay more for add-on
- 20. Limitation Skilled and experienced estimator is needed Minor problem on detections – Rebars detection – Line cannot be overlapped
- 22. Buildsoft - Australian company, head office located in Sydney, Australia - Established in 1986 - Develop and market computer software - Affordable price - Produce powerful but user-friendly
- 23. Buildsoft Products • MudShark • Global • Cubit
- 24. Function Cubit Lite, Cubit, & Cubit Pro Natural estimating 3D takeoff
- 25. Function Automatic Plan Revision Price lists
- 26. Function Job Analysis Reports
- 27. Limitations • Permanent deletion • Typing errors • Boot Camp or Virtual Window needed • High Utility Bills
- 28. Vico Software
- 29. Introduction Use to reduce risk and optimize schedule
- 30. Introduction More than hundreds of building projects to date have proven the benefits of the solutions and services of Vico software
- 31. Introduction Provides construction software and services to the commercial building industry.
- 32. Function 3D BIM for Visualization
- 33. Function 3D BIM for Clash Detection
- 34. Function 3D BIM for Quantity Takeoff
- 35. Function 4D BIM for Scheduling and Production Control
- 36. Function 5D BIM for Estimating
- 38. Function Quantity survey- can audit the quantities visually in 3D, and it can explain the definition of the locations of a visual and intuitive way. Budgeting-budget automatically updated if there are changes to the model or design Physical Planning- the tasks linked to budget and enriched with the respective inputs
- 39. Function Construction Sequence Simulation- automatic update of the simulation if there are changes to the model and planning Reports- export all the information to excel and the information in a format adapted to a more agile import into ERP. Control and forecasting planning-the effective working hours and the forecast based on actual yields from the history of the work.
- 40. Limitations Could not be used for more model file-Only one model file can be operated at one time by using this method, hence it will take longer time to complete the project Earn Lesser money- Vico software can’t complete few project at one time, so the company can’t accept more job, less job causes less money to earn.
- 41. Feature Glodon CostX Cubit Vico Simplicity Yes Yes No; Manual Input No; Only one 3D Model at a time Taking-Off Yes Yes Yes Yes Applicable for Architect & Engineer No No No No Able to read different types of drawings Yes Yes Yes Yes Able to export into other formats Yes No Only Microsoft Excel Yes
- 42. Part B BIM VS CAD VS MANUAL MEASUREMENT
- 43. Briefing Stage
- 44. BIM Benefits Contraints Faster decision making process High investment in cost, time, and training Feasibility study Lack of standardisation and inappropriate pricing formatFloor Area/Volume Elemental Methods
- 45. CAD Benefits Contraints Improve the quality of the design Training required Provide the data base for manufacturing Expenses on software Lack of Information Backup
- 46. Manual measurement Benefits Contraints Cost Effective Cost Plan No Training Required
- 47. Design Stage
- 48. BIM Benefits Constraints Ability to see a clearer picture of the design of a building. Requires knowledgeable members. Enhances efficiency Adaption against time Reduces material usage Cost
- 49. CAD Benefits Constraints Draw to scale Requires update of skills Draw efficiently Inability to retrieve quantities for sketches
- 51. BIM Benefits Constraints Easy measurement Risk on legal responsibilitiesSub-contractor quotation Save time and effective
- 52. CAD Benefits Constraints On-screen take off Unable to prepare bill of quantities High accuracy
- 53. Manual Measurement Benefits Constraints Save cost Time consuming Create clearer images Human error
- 55. BIM Benefit Constraints Speed of Construction Standardization procedure Project Management External parameters High Accuracy leading to waste reduction
- 56. CAD Benefit Constraints Standardization procedure Limited measurements Improves communication vis clarity Operating expenses on site
- 57. Manual Measurement Benefits Constraints Cost effective Dimensional restriction No Training required Time Consuming
- 59. BIM Benefits Constraints Locating Hidden Building Components Resources Constraints Real-time Data Compatibility Space Management
- 60. CAD Benefits Constraints Extension of Information Limited Information Commonly Usable
- 61. Manual Measurement Benefits Constraints Easily Obtain Information Time needed after commissioning Straightforward Information Limited Information
