Key Factors Affecting Productivity
• Acceleration• Weather• Scope Changes• Trade Stacking• Overtime
![Page 9: VERTEX - AACE Northeast Total Cost Management Symposium 2016](https://reader035.fdocuments.in/reader035/viewer/2022062223/587a79411a28abf0468b59fd/html5/thumbnails/9.jpg)
Estimating Lost Productivity
• AACE 25R-03 [1]– Option A: Project Specific Studies– Option B: Project Comparison Studies– Option C: Specialty Industry Studies– Option D: General Industry Studies– Option E: Cost Basis
![Page 10: VERTEX - AACE Northeast Total Cost Management Symposium 2016](https://reader035.fdocuments.in/reader035/viewer/2022062223/587a79411a28abf0468b59fd/html5/thumbnails/10.jpg)
Option A – Project Specific Studies
• Project Specific• Require contemporaneous documentation
![Page 11: VERTEX - AACE Northeast Total Cost Management Symposium 2016](https://reader035.fdocuments.in/reader035/viewer/2022062223/587a79411a28abf0468b59fd/html5/thumbnails/11.jpg)
Option A – Project Specific Studies
• Measured Mile • EV Analysis • Work Sampling Method • Craftsmen Questionnaire Sampling Method
![Page 12: VERTEX - AACE Northeast Total Cost Management Symposium 2016](https://reader035.fdocuments.in/reader035/viewer/2022062223/587a79411a28abf0468b59fd/html5/thumbnails/12.jpg)
Option B – Project Comparison Studies
• Comparable Work Study• Comparable Project Study
![Page 13: VERTEX - AACE Northeast Total Cost Management Symposium 2016](https://reader035.fdocuments.in/reader035/viewer/2022062223/587a79411a28abf0468b59fd/html5/thumbnails/13.jpg)
Option C – Specialty Industry Studies
• Studies of specific types of problems– Acceleration– Changes/Cumulative Impact– Learning Curve– Overtime– Weather
![Page 14: VERTEX - AACE Northeast Total Cost Management Symposium 2016](https://reader035.fdocuments.in/reader035/viewer/2022062223/587a79411a28abf0468b59fd/html5/thumbnails/14.jpg)
Specialty Industry Studies – Key Challenges
• Entitlement1. Liability 2. Causation
• Justification of Method• Applicability• Reasonableness of Results• Other Considerations
![Page 15: VERTEX - AACE Northeast Total Cost Management Symposium 2016](https://reader035.fdocuments.in/reader035/viewer/2022062223/587a79411a28abf0468b59fd/html5/thumbnails/15.jpg)
Liability
- First step in demonstrating entitlement- Usually established by a contract provision or
the accused party’s breach of contract- Key is to use the contract language to your
advantage
![Page 16: VERTEX - AACE Northeast Total Cost Management Symposium 2016](https://reader035.fdocuments.in/reader035/viewer/2022062223/587a79411a28abf0468b59fd/html5/thumbnails/16.jpg)
Causation
1. Demonstrate the accused party caused the loss
2. Provide evidence that claimant did not contribute to the loss
![Page 17: VERTEX - AACE Northeast Total Cost Management Symposium 2016](https://reader035.fdocuments.in/reader035/viewer/2022062223/587a79411a28abf0468b59fd/html5/thumbnails/17.jpg)
Keys to Entitlement- Adherence to notice requirements- Impact was unforeseeable- Impact was beyond claimant’s control- Claimant is not responsible - Damages are recoverable under the contract- Disruption resulted in changed performance or
increased cost
![Page 18: VERTEX - AACE Northeast Total Cost Management Symposium 2016](https://reader035.fdocuments.in/reader035/viewer/2022062223/587a79411a28abf0468b59fd/html5/thumbnails/18.jpg)
Justify Calculation Method
- Why couldn’t you use one of the more preferred methods?
- Opposition may attempt to use a superior method to demonstrate claimant’s damages are overvalued
![Page 19: VERTEX - AACE Northeast Total Cost Management Symposium 2016](https://reader035.fdocuments.in/reader035/viewer/2022062223/587a79411a28abf0468b59fd/html5/thumbnails/19.jpg)
Applicability- The data used in an industry study applies to a very
specific project environment- Critical to document the surrounding circumstances of the
claim situation
- When choosing a study ask yourself:- Why/Where/When was the study performed?- How closely does the study tie to my scenario?- In what way does the study differ from the case at hand?[2]
![Page 20: VERTEX - AACE Northeast Total Cost Management Symposium 2016](https://reader035.fdocuments.in/reader035/viewer/2022062223/587a79411a28abf0468b59fd/html5/thumbnails/20.jpg)
Applicability
- Project Size- Project Type- Similar Trade- Scope of work- Circumstances- Experience of labor force
![Page 21: VERTEX - AACE Northeast Total Cost Management Symposium 2016](https://reader035.fdocuments.in/reader035/viewer/2022062223/587a79411a28abf0468b59fd/html5/thumbnails/21.jpg)
Applicability - Example
- Leonard Study is only applicable to projects experiencing greater than 10-15% change orders (measured by labor hours) and only until a certain point. [3]
![Page 22: VERTEX - AACE Northeast Total Cost Management Symposium 2016](https://reader035.fdocuments.in/reader035/viewer/2022062223/587a79411a28abf0468b59fd/html5/thumbnails/22.jpg)
Credibility
• Is the study of objective?• Does it provide representative value?• Does the study use recent data?• Are intervening variables considered?
![Page 23: VERTEX - AACE Northeast Total Cost Management Symposium 2016](https://reader035.fdocuments.in/reader035/viewer/2022062223/587a79411a28abf0468b59fd/html5/thumbnails/23.jpg)
Credibility
![Page 24: VERTEX - AACE Northeast Total Cost Management Symposium 2016](https://reader035.fdocuments.in/reader035/viewer/2022062223/587a79411a28abf0468b59fd/html5/thumbnails/24.jpg)
Credibility
• Did not rely on original data– Relied on flawed data from an earlier study by The Business
Roundtable• The nature of the work or the trades involved was not
disclosed in the original study
![Page 25: VERTEX - AACE Northeast Total Cost Management Symposium 2016](https://reader035.fdocuments.in/reader035/viewer/2022062223/587a79411a28abf0468b59fd/html5/thumbnails/25.jpg)
Reasonability
- Demonstrating another quantification yields similar results will bolster your position
![Page 26: VERTEX - AACE Northeast Total Cost Management Symposium 2016](https://reader035.fdocuments.in/reader035/viewer/2022062223/587a79411a28abf0468b59fd/html5/thumbnails/26.jpg)
Reasonability - Example
- Specialty Industry Study Analysis $500,000
- Modified Total Cost “Sanity Check”- $100,000 BAD- $525,000 GOOD

Other Considerations
- Contemporaneous Documentation- Expert Testimony
![Page 28: VERTEX - AACE Northeast Total Cost Management Symposium 2016](https://reader035.fdocuments.in/reader035/viewer/2022062223/587a79411a28abf0468b59fd/html5/thumbnails/28.jpg)
Summary of Key Challenges
- Demonstrating Entitlement- Justify Quantification Method- Applicability of Study- Credibility - Reasonableness of Results
