  1. Performance Specifications Presented By: Diane Heckemeyer, P.E. State Design Engineer Bruce Green, P.E. Technical Support Engineer Kirsten Munck, P.E. Standards Specialist

  2. Performance Specifications What are they?

  3. Types of Specifications: • (Listed in Hierarchical Order) • Performance • End Result • Performance-Based • Performance-Related • Statistical • QC/QA • Method

  4. Examples of most can be found in the new spec book. The type of work will dictate the type of specification used.

  5. MoDOT’s Goal: Eliminate method specifications wherever possible.

  6. Performance: Describes how the finished product should perform over time. Other than warranties/guarantees, performance specs had not been used in highway construction.

  7. Method: Specification that directs the contractor to use specified material in definite proportions and specific types of equipment and methods to place the material.

  8. How are they different? Rather than providing the detailed steps, we tell the contractor what finished product we want.

  9. A BRIEF history of performance specifications.

  10. History: • June 1994 - US Secretary of Defense directed the reform of military specifications and standards. • The idea caught on, and state DOT’s began using them in limited applications. • As of November 2000, over half of the state DOT’s were using performance specifications in one form or another.

  11. Typical applications include: Pavements Bridge Painting Striping Landscaping Design/Build Projects

  12. Missouri will be the first state to entirely revise its specifications to performance wherever possible.

  13. Why Use Performance Specifications? • Encourage innovative thinking • Promote new construction techniques • Minimize restrictions by state government • Allow contractors to showcase their work • Lower costs for the taxpayer

  14. The PROCESS How did we get where we are now?

  15. Late in the Summer of 2001… A Steering Committee was formed including individuals representing: • Construction and Materials • Pat McDaniel • Dennis Bryant • Vicki Woods • Design • Kirsten Munck • A District • Phil Knott-D9 • FHWA • Mary Ridgeway • Industry • Rusty Crane • Tom Kraus (Millstone Bangert)  

  16. January 2002 – • with the recommendations of the Steering Committee… • A Project Coordinator was designated in Design. • Each section of the spec book was assigned to a • functional unit. • Functional Unit Leaders assigned team leaders. • Deadline for submitting the first draft was • December 31, 2002. • Training was provided to most participants.

  17. Teams consisted of: • MoDOT Employees • FHWA Personnel • 140 Industry Representatives More than 250 individuals served on 76 teams.

  18. In addition to the current specification, teams received the following documents to revise relating to their specs: • Standard Plans • Job Special Provisions • General Special Provisions • Pay Items

  19. All draft specifications were posted on the website for a 30-day comment period. Web Site: http://www.modot.mo.gov/design/specbook/perffiles.htm

  20. After the comment period, • each specification passed through • a series of approvals: • Engineering Policy Subcommittee (Technical Experts) • Engineering Policy Committee (Functional Unit Leaders) • The Directors of Project Development and Project Operations • Chief Engineer

  21. The entire revised book was posted for final 30-day comment period January 5, 2004. Release Date: June 1, 2004

  22. Effective Date: July 1, 2004

  23. How does all of this affect Designers? Conversion from method specs to performance specs – very little. Revisions to existing specifications, job special provisions and new specs will.

  24. Standard JSP’s and Pay Items will affect designers the most. Many JSP’s were incorporated into the specifications.

  25. Division 100 • General Provisions • Sec 101 – Definitions for “Shall” and “Will” were added • Sec 104 – Incorporated Railroad Liability Insurance JSP. • Sec 105 – Revised ranking of contract documents: • Project Specific Drawings ranked ahead of General Provisions. • Standard Drawings moved behind Standard Specs.
