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
slide3

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
slide4

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
slide5

GOALS AND OBJECTIVES

Shorten Process Schedule

Minimize Cost

Improve Quality

slide6

RRR Scoping Report Process

Involves input from:

FDOT

  • Team-up

Consultants

  • PD&E
  • Planning
  • Traffic Operations
  • Design
  • Materials
  • PTO
  • Maintenance
  • Structures
  • Environmental
  • Pavement Design
  • Construction

Scope Report

slide7

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

slide8

CURRENT PROCESS - FLOW CHART, cont.

  • Engineering Analysis
  • Review existingconditions
  • 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

CURRENT PROCESS - SCHEDULE

NTP Scoping Report

slide10

CURRENT SCOPING PROCESS

ADVANTAGES

Acceptable Information for Design Phase

Maintains Coordination with Consultants

Identifies Sources and Types of Information

slide11

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

slide13

PROPOSED PROCESS - SCHEDULE

NTP Scoping Report

slide14

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.
slide15

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.
slide16

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
slide17

PROPOSED PROCESS

Identify Roadway Deficiencies and Substandard Conditions

The consultant will go to the site to evaluatethe 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.

slide18

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.

slide19

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.

slide20

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.

slide21

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.

slide22

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.

slide23

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.

slide24

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.

slide25

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.

slide26

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

slide27

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

Current vs. Proposed Time Comparison

slide31

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
