Minimum Standards and
Congruence of Interests
Two Distinct Areas
During Design
Engineering Responsibility (MUTCD, Engineers Judgment, Designed Construction Phasing, Minimizing Impact to the Traveling Public)
Under Construction
Contractor Responsibility ( Compliance with Specification, Adjusting Construction Phasing, Maintenance of Traffic Operations, Minimizing Impact to the Traveling Public)
Design and Engineering
Manual of Uniform Traffic Control Devices
Sets Minimum Design Standards and Devices
Engineers Judgment
Experience and Knowledge to Adjust or Modify
Minimum Design Standards and Devices
Designed Construction Phasing
Anticipated Contractor Phasing for Construction
Minimizing Impact to the Traveling Public
Delays, Route Redundancy, Changes in MOT
Operations
Contractors Responsibility
Compliance with the Project Specifications
What Traffic Control or Traffic Operations Specification Applies
Adjustment of Construction Phasing
How to Modify during Construction-TCP
Maintenance of Traffic Operations
Duration, Sequence, Locations, Devices, Engineering Standards
Minimizing Impact to the Traveling Public
Detours, Route Redundancy, Travel Times/Distances, Public Information/Notices
Congruence of Interests through
Areas of Conflict
Construction Phasing
Designers/Engineers need to Optimize Flexibility in Traffic Control Plans and Anticipated Phasing- Contractor/Design Engineer Workshops (Means, Methods, Costs)
Contractors need to understand what is in Project Specification Contract Documents Direction, Limitations, Standards-Design/Engineer/Contractor Workshops (Design Standards, Phased EW, Costs of Delays)
Why is Impact to the Traveling
Public Important
For Engineer
Contractor understands phasing-no change=perfect
TCP
Minimal time delays for public-transparent between
construction and normal operations
For Contractor
Easy to Bid-easy to modify
Minimal costs
Good PR with the Citizens affected by the project
Why was the Change “Win-Win”
Contractor was able to work in an expanded
work zone (directly applicable to means and
methods, and costs)
TCP change provided safer traffic
operations for users of intersection and
work zone ( directly applicable to reduced
traffic conflicts, associated time delays, and
costs-resulted in good PR)
Who else won
The Department
Increased safety at Intersection under
construction
Contractor completed work more quickly
Business Owners/Private Landowners,
and Roadway users were minimally
inconvenienced during construction
Where do we go from Here?
Major area of unknown
Actual Contractor Construction Phasing
Affects - TCP, MOT, Revised TCP’s,
Earthwork, Time, and Costs
Your Chance to Affect Change
Questionnaire
Built around 2 conditions
Full Reconstruction with complicated phasing
Maintenance and rehabilitation
Typical or Common areas of use
Interstate and NHS routes
State Oversight and State Routes
