  1. CR3683-L Integrating Autodesk® Quantity Takeoff and Timberline Estimating Kevin R. Miller Associate Professor, Brigham Young University Jason Dodds, Autodesk

  2. Presentation Format • Please raise your hand if you have a question and a Lab Assistant will help you. • All the material that we will cover is in the handout. • Because of the time limitations, questions will only be answered at the end of the session. • Feel free to email me (kmiller@byu.edu) with follow-up questions.

  3. Estimating today • When was the last time you estimate a set of plans that were 100%? • How long does it take you to do the takeoffs? • Who bears the risk today if the plans aren’t complete? • How do you cope with plans that aren’t complete?

  4. Takeoff Process (Traditional Plans) • Benefits • Become familiar with the project • Find problem areas and identify risk and constructability issues • Value engineering • Downside • Time consuming (Detailed Estimates) • May miss something • Transferring quantities from takeoff sheets to Estimating software tedious and non productive

  5. What do we want from the Model? • Accurate quantities • Less takeoff time • Better visualization of project • Subs to understand the project and their scopes. • Competitive edge • Clash detection • Visual means to communicate to clients

  6. General Model Sales Pitch • Push the button. • Costs are generated. • The 4/5 D model is generated. • All the work is done. • Looks good, sales software. • Not necessarily doable without a lot of extra work.

  7. Model World Today • Not the magical pushing a button and the estimate is done. • No such thing as a 100% Model • Costs come from your estimating database not Means or some other source • The liability that exists with 2D drawings exist with 3D models • Estimating with BIM – Risk shouldn’t change or shift • Takeoffs consume less time • More time verifying what is modeled is constructable • Better understanding of design intent

  8. Estimating from the Model or Not? • Do I really want to work from the Model? • No, I want static drawings that don’t change so there is an accurate history of the costs for the project • No, I don’t want the potential to change the drawings because I’m and estimator, not a modeler • No, the file size of the model would really slow me and my computer down. • DWF file (a read-only copy of the model) addresses the above concerns

  9. What can we really get from the Model? • Counts • Lengths • Areas • Concerns about the wall areas and volumes • Use Length * Height for areas • Use Length * Height * Width for volumes • Do these concerns mean don’t use the model? NO, just understand how the quantities are being calculated. • When in doubt, check the quantity calculation.

  10. Timberline Opportunities • QTO integrates seamlessly into Timberline. • Use Timberline for complete estimates instead of jumping to Excel • Cleanup and optimize the estimating DB • Too much legacy junk in estimating DB’s • Every item in the DB should have a formula • QTO integrates better with Timberline than Timberline does

  11. Requirements: Model Estimating • Your Timberline DB • QTO • QTO/Timberline plug in • 3D model (You may need to ask for it.) • 2D modeled sheets • Allows you to perform takeoff for the items not modeled. • DWF file format • May use PDF, jpg etc files but they will not link to the 3D model.

  12. Model Estimating in the Classroom • Takeoffs taking less time • Test scores are going up and takeoffs more accurate. • Model estimating is taught in conjunction with clash detection and 4D sequencing.
