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 ([email protected]) 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.
