RAISED CROSSWALKS (TRAFFIC CALMING INITIATIVE GRANT)

100. SPECIAL CONDITIONS:

101. GENERAL:

101.1 The Contractor shall not subcontract any work to be performed under this contract without the written consent of the City.

Raised crosswalks are flush with the height of the sidewalk. The crosswalk table is typically at least 10-feet wide and designed to allow the front and rear wheels of a passenger vehicle to be on top of the table at the same time.

Detectable warnings (truncated domes) and curb ramps are installed at the street edge for pedestrians with impaired vision.

102.2 This contract involves approximately 22 raised crosswalk locations throughout the City.

The Contractor shall conduct the work and shall cooperate with such other parties so as to cause minimum interference with their operations and as the Engineer may direct. No additional compensation will be paid to the Contractor for any delay or inconvenience due to material shortages or delays due to the operations of such other parties doing the work or for any

Special Conditions for delays on construction due to the encountering of existing unmarked/mismarked utilities.

103.2 The Contractor shall have available at all times, a competent Superintendent or Foreman authorized to act for the Contractor as agent on the work, who thoroughly understands the plans and specifications and who shall receive instructions from the Engineer.

105. ROADS AND EASEMENTS:

105.4 Near the end of construction, the Contractor shall return the surface to its original condition, replacing topsoil, grass and shrubs as directed by the Engineer.

107.2 The hoppers of the trucks carrying loose materials such as sand, stone, cement and excavated materials shall be tight, leak proof and covered to prevent any spillage during hauling operations.

107.3 Prior to leaving the project area, the load on the truck shall be trimmed, by hand if necessary, and truck sides, wheels, tires and all other projections shall be swept clean of all materials of any kind that may be shaken loose in transit.

108. CLEANING OF CITY STREETS:

108.1 The Contractor shall keep all streets clean of debris resulting from his operations.

108.2 Street cleaning by use of compressed air direct blasting or power brooms without dust control shall be strictly prohibited.

108.3 If the Contractor fails to keep any street cleaned of debris resulting from his operations, creating a public nuisance, he shall be notified in writing by the Engineer to clean the street and remove the nuisance. If, within 12 hours after the receipt of such notice, the Contractor fails to clean the street, the Engineer shall order the street cleaned by the Department of Public Works and all cost of such cleaning shall be deducted from the Contractor's progress payment.
