6-152SECTIO N 632 – RAILROA D FLAGGERS

632.0 1 DESCRIPTION . This work shall consist of maintaining Operating Railroad traffic and coordinating with the Agency and the Operating Railroad for inspection and review of the Contractor’s work in conjunction with construction operations. A railroad flagger shall be requested any time construction operations will be within 25 feet of the nearest rail or within the Operating Railroad right -of- way, whichever is furthest. 632.0 2 GENERA L REQUIREMENTS . A railroad flagger shall be a person who is furnished, employed, and qualified by the Operating Railroad . When, as stipulated in the Contract , or in the opinion of the Engineer and the Operating Railroad, the construction work would cause hazard to the safe operation of trains and other facilities in the Operating Railroad right -of-way, including signal and communic ation lines, the Operating Railroad will furnish the necessary qualified employees to protect their trains and other facilities. The Contractor shall provide advanced notice to the Operating Railroad prior to the commencement of any work , or any portion of the work , over or adjacent to the Operating Railroad right -of-way, so that necessary arrangements can be made by the Operating Railroad to protect Operating Railroad traffic. Railroad flaggers shall be required whenever the Contractor is performing work over, under, or adjacent to the Operating Railroad tracks or right -of-way, such as excavation, sheeting, shoring, erection or removal of forms , or handling material . Railroad flaggers sha ll also be required whenever equipment is used which , by swinging over or by failure , could foul the track, or when any other type of work is being performed that, in the opinion of the Engineer or the Operating Railroad, requires such service. The Contrac tor shall be required to plan, coordinate, and organize the work effort in a way that shall absolutely minimize the use and number of Operating Railroad protective personnel required . The Agency and the Operating Railroad will review and approve all Contra ctor work schedules prior to the commencement of work and prior to the assignment of protective personnel . Misuse of these protective services by the Contractor due to inadequate work procedures will not be allowed and shall be sufficient cause for the Age ncy to require the Contractor to bear all inappropriate costs. Operating Railroad train crews necessary for the operation of Contractor -scheduled work trains or Contractor -owned or leased locomotive equipment shall not be paid by the Agency under this section , as all such costs will be considered incidental to the Contractor’s work and therefore shall be entirely borne by the Contractor.
