Best Practice

BEST PRACTICE:

G4−5: Standard Specification that Requires the Contractor to Correct Deficient Traffic Control

DESCRIPTION:

The contractor is required to respond within 30 minutes to any request from the agency engineer for re−aligning, replacing, or moving traffic control devices or moveable concrete barrier, or otherwise re−establishing compliance with the Maintenance of Traffic Specifications. The contractor will be subject to a monetary reduction for each incident per day when the agency engineer determines that the contractor is not in full compliance with the specifications. The penalty is $500 on the Illinois Tollway and $2,500 on Illinois Department of Transportation projects.

REASON(S) FOR ADOPTING:

It is imperative to have proper traffic control to maintain traffic flow and safety to the public. This specification includes a time frame for the contractor to respond to the agency engineer's request to correct deficient traffic control, and the penalty gives the engineer an instrument to further enforce the specification.

PRIMARY BENEFIT(S):

Traffic control is better maintained even without the engineer requesting the contractor to correct any deficiencies. Ultimately, this specification helps provide a safer work zone for the public with both the engineer and the contractor attentive to traffic control deficiencies.

MOST APPLICABLE LOCATION(S)/PROJECT(S):

This practice is a standard specification and is incorporated into every State and Tollway project.
