CR3683-L Integrating Autodesk® Quantity Takeoff and Timberline EstimatingKevin R. MillerAssociate Professor, Brigham Young UniversityJason Dodds, Autodesk

Presentation FormatPlease 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.

Estimating todayWhen 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?

Takeoff Process (Traditional Plans)

BenefitsBecome familiar with the projectFind problem areas and identify risk and constructability

issuesValue engineering

DownsideTime consuming (Detailed Estimates)May miss somethingTransferring quantities from takeoff sheets to Estimating

software tedious and non productive

What do we want from the Model?Accurate quantitiesLess takeoff timeBetter visualization of projectSubs to understand the project and their scopes.Competitive edge

Clash detectionVisual means to communicate to clients

General Model Sales PitchPush 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.

Model World TodayNot the magical pushing a button and the estimate is done.No such thing as a 100% ModelCosts come from your estimating database not Means or some

other sourceThe liability that exists with 2D drawings exist with 3D models

Estimating with BIM – Risk shouldn’t change or shiftTakeoffs consume less timeMore time verifying what is modeled is constructableBetter understanding of design intent

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

What can we really get from the Model?CountsLengthsAreas

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.

Timberline OpportunitiesQTO integrates seamlessly into Timberline.

Use Timberline for complete estimates instead of jumping to Excel

Cleanup and optimize the estimating DBToo much legacy junk in estimating DB’sEvery item in the DB should have a formula

QTO integrates better with Timberline than Timberline does

Requirements: Model EstimatingYour Timberline DBQTOQTO/Timberline plug in3D model (You may need to ask for it.)2D modeled sheets

Allows you to perform takeoff for the items not modeled.DWF file formatMay use PDF, jpg etc files but they will not link to the 3D

model.

Model Estimating in the ClassroomTakeoffs taking less timeTest scores are going up and takeoffs more accurate.Model estimating is taught in conjunction with clash

detection and 4D sequencing.
