1. FLORIDA INTERNATIONAL UNIVERSITY Six Sigma Project STREAMLINE RESURFACING SCOPING PROCESS FOR FDOT PROJECTS By : William Salisbury Auraliz Benitez Edward Schumann Pastor Gonzalez

2. Introduction • Florida Department of Transportation (FDOT) • State Highway System consists of 12,093 miles of roadway and 6,549 bridges • 800 Aviation facilities • 28 Fixed-route systems • 1 Commuter rail system (Tri-Rail) • 14 Seaports • 2,796 Railway miles • $33.8 billion in the five-year work program • Many opportunities for Six Sigma implementation

3. RRR Projects • Resurfacing, Restoration and Rehabilitation (RRR) Projects • This is the most common type of FDOT project. The goal is to extend the service life of an existing pavement and enhance highway safety. • Construction typically includes a new layer of asphalt and safety improvements such as improved traffic signalization • Requires involvement and coordination between over 10 areas of FDOT • Multiple steps in the process from Planning to Construction

4. RRR Projects – Scoping Report • Scoping Report for RRR Projects • Overseen by the FDOT Project Development and Engineering Office • Typically conducted by Consultant Engineering firms • Section of roadway in need of work is selected by Planning office based on the pavement condition and safety concerns • Consultant evaluates roadway • Provides recommendations for improvement in the form of a Scoping Report

5. GOALS AND OBJECTIVES • Shorten Process Schedule • Minimize Cost • Improve Quality

6. RRR Scoping Report Process • Involves input from: • Team-up • Consultants • FDOT • PD&E • Planning • Traffic Operations • Design • Materials • PTO • Maintenance • Structures • Environmental • Pavement Design • Construction • Scope Report

7. CURRENT PROCESS - FLOW CHART NTP – Notice to Proceed Collection and preparation of documents Decision making Terminators - Presentations and reports submittal Processes - Engineering Analysis Work performed by Consultants

8. CURRENT PROCESS - FLOW CHART, cont. • Engineering Analysis • Review existing conditions • Identify deficiencies that do not meet FDOT standards • Benefit/Cost analysis • Draft Report • Office • Field • Documents deficiencies that do not meet ADA standards • Identify • Analyze • Recommend

9. CURRENT PROCESS - SCHEDULE NTP Scoping Report

10. CURRENT SCOPING PROCESS ADVANTAGES • Acceptable Information for Design Phase • Maintains Coordination with Consultants • Identifies Sources and Types of Information

11. CURRENT SCOPING PROCESS DISADVANTAGES • Long Duration for Report Development • High Cost for Report Preparation • Coordination within the Department and Other Agencies could be Improved • Long Delays Receiving Input Data Documents • Reports can be Ready Well Before Design Phase

12. PROPOSED PROCESS - FLOW CHART

13. PROPOSED PROCESS - SCHEDULE NTP Scoping Report

14. PROPOSED PROCESS • Prepare ADA Report: 15 days to at NTP • The Public Transportation Office at FDOT will go to the site before NTP to investigate items related to Americans with Disabilities Act (ADA); thus creating the report earlier.

15. PROPOSED PROCESS • Office: Review physical, operating and safety conditions: 5 Days to 3 Days • The FDOT will standardize guidelines to create a checklist that will be used to make it easier and quicker for the consultant to write a report on these conditions.

16. PROPOSED PROCESS • Engineering Analysis: 30 Days to 15 Days • All work can be done simultaneously • Identify Roadway Deficiencies and Substandard Conditions • Safety Analysis of Corridor and Intersections • Level of Service Assessment of Corridors and Intersections • Preliminary Identify Design Exceptions and Variations • Pavement Design of Corridor • Evaluate Flooding and Existing Drainage

17. PROPOSED PROCESS • Identify Roadway Deficiencies and Substandard Conditions • The consultant will go to the site to evaluate the road to find problem areas. The as-builts are provided so they can compare those areas to the plans to try to find a reason for the deficiency. If there is a bridge, structures will provide them a bridge inspection report to save them time.

18. PROPOSED PROCESS • Safety Analysis of Corridor and Intersections • Traffic Operations provides high crash list and 5-year crash data for the consultant to review and analyze.

19. PROPOSED PROCESS • Level of Service Assessment of Corridors and Intersections • Planning provides the annual average daily traffic (AADT) reports, 18 kips Equivalent Single Axle Load (ESAL) Report, and Straight line diagrams. The county also provided the signal updates for each intersection. Using all this information, the level of service assessment can be calculated.

20. PROPOSED PROCESS • Preliminary Identify Design Exceptions and Variations • This step has been moved into the Engineering Analysis category because it is only a preliminary identification step. This is only what can be seen with the eye and therefore we do not need a set of plans to evaluate.

21. PROPOSED PROCESS • Pavement Design of Corridor • The FDOT now provides the Resilient Modulus Recommendation Report and Pavement Evaluation Coring and Condition Report at NTP. Providing these documents allows the consultant to begin the designing at day 1 of 15 instead of having to wait for these reports that could take up to two weeks to prepare.

22. PROPOSED PROCESS • Evaluate Flooding and Existing Drainage • Working in conjunction with the maintenance department, we are able to provide the drainage complaints and deficiencies reports at NTP as opposed to during development with the old process.

23. PROPOSED PROCESS • Added  Development of Environmental Document (not on critical path) • Due to the time restraints of the Engineering Analysis, this process, which is completed by FDOT, can be completed without impacting the consultant’s time.

24. PROPOSED PROCESS • Eliminated  FDOT Review Comments Cost Estimate • This step was found to be unnecessary as every aspect (including cost estimate) will get reviewed in a later process after the scoping report.

25. PROPOSED PROCESS • Prepare and Submit Draft Scoping Report: 10 Days to 7 Days • All work should be completed by this point. This time should be solely used to allow for the consultant to compile all work done in pervious steps and should not have time to make-up work that should already be finished.

26. PROPOSED SCOPING PROCESS ADVANTAGES • Cost Savings • Improves Coordination within the Department and with Other Agencies • Early Identification of Sources and Types of Information • Reduces Time for Report Preparation • Provides Multi-disciplinary Review

27. PROPOSED SCOPING PROCESS DISADVANTAGES • Requires Department to Have Input Data Documents Available On Time • Coordination within the Department and Other Agencies could be Improved • Long Delays Receiving Input Data Documents • Reports can be Ready Well Before Design Phase

28. SIX SIGMA ANALYSIS Current Process Cost Analysis

29. SIX SIGMA ANALYSIS Proposed Process Cost Analysis

30. SIX SIGMA ANALYSIS Current vs. Proposed Time Comparison

31. CONCLUSION • Minimize Cost • Savings of $ 11,610 per report with average annual savings of over $100,000 • Shorten Process Schedule • Reducing the total days from 190 to 113 days • Improve Quality • New Process mapping been implemented with future improvements under analysis
