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

Original TCP

Revised TCP

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

Mobility for Everyone
