If the Contractor is negligent in adhering to the established time schedules, he shall be subject to an hourly charge assessed at a rate of $500.00 per hour for each hour or any portion thereof with which the Engineer determines that the Contractor has not complied (C) Unless otherwise approved by the Engineer, any temporary lane closure that is adjacent to traffic, and is extending to or beyond 1000 feet shall have a minimum of one Type III barricade, or three drums, placed in the closed lane for every 1000 feet of extension. Any lane closure that is adjacent to traffic and inplace 3 days or more, shall use the Type III barricade only. (D) All lane closures shall have Drum (Type B) Channelizers with florescent reflectorized sheeting in the lane closure taper and in any shifts in traffic alignment. (E) Short Term Duration lane closures will not be permitted during inclement weather, nor any other time when, in the opinion of the Engineer, the lane closure will be a greater than normal hazard to traffic. When working on the shoulder or median the Contractor shall install the traffic control according to Layout 2 (Work on Shoulder) of the Field Manual. Notes 1 and 2 are deleted on Layout 2. (G) Temporary lane restrictions and/or closures for removing and/or erecting overhead structures are permitted between the hours of 9 A.M. and P.M. as approved by the Engineer. If the Contractor requests to close the road and the Engineer approves that it is necessary to temporarily detour traffic in order to remove or set the structures, the Contractor shall furnish the detour as directed by the Engineer. The temporary detour shall be incidental work. If the Contractor is negligent in adhering to the established time schedules, he shall be subject to an hourly charge assessed at a rate of $1500.00 per hour for each hour or any portion thereof with which the Engineer determines that the Contractor has not complied. The Contractor may stop all traffic on any road open to traffic to erect or remove overhead structures for periods not to exceed fifteen minutes only from 1:30 A.M. to 5:00 A.M. The Contractor shall allow sufficient clearance time between stopped periods to minimize the delay to traffic. If the Contractor is negligent in adhering to the established time schedules, he shall be subject to an hourly charge assessed at a rate of $1500.00 per hour for each hour or any portion thereof with which the Engineer determines that the Contractor has not complied. (H) No center lane closures will be permitted. Only double lane closures as shown in the Field Manual will be allowed at the times as directed by the Engineer. This may require night lane closures if traffic volumes warrant. (I) The Contractor shall maintain a minimum of 1.25 miles [two km] between temporary lane closures, except if allowed by the Engineer. (J) Flashing Arrow Boards The Contractor shall provide one vehicle or trailer mounted flashing arrow board for each lane of each work area where traffic is restricted. The arrow board shall meet the requirements of the MN MUTCD, and be on the Temporary Traffic Control Electronic Equipment Approved/Qualified Products List for "Flashing Arrow Boards" found at: http://www.dot.state.mn.us/products/temporarytrafficcontrol/tccelectronicequipment.html. The flashing arrow board shall be equipped with a light that is visible to personnel in the work area to indicate that the unit is in operation. All costs incurred to provide the flashing arrow board shall be incidental. It is imperative that the Contractor continually operate each Flashing Arrow Board at maximum legibility. Many factors, such as mechanical problems, insufficient charging, incorrect intensity settings, or other factors can degrade performance.
