The Railroad representative will: <br /> <br />a. Determine approximate location of trains and advise the Contractor the <br />appropriate amount of time available for the blasting operation and clean <br />up. <br /> <br />b. Have the authority to order discontinuance of blasting if, in his opinion, blasting <br />is too hazardous or is not in accord with these special provisions. <br /> <br />3. The Contractor must hire, at no expense to the Railroad, a qualified and independent <br />blasting consultant to oversee the use of explosives. The blasting consultant will: <br /> <br />a.

Submit a letter acknowledging that he has been engaged to oversee the entire <br />blasting operation and that he approves of the blasting plan. <br /> <br />e. Furnish copies of all vibration readings to the Railroad representative <br />immediately after each blast. The representative will sign and date the <br />seismograph tapes after each shot to verify the readings are for that specific <br />shot. <br /> <br />f. Advise the Railroad representative as to the safety of the operation and notify <br />him of any modifications to the blasting operation as the work progresses. <br /> <br />4. The request for permission to use explosives on the Railroad’s Right-of-Way shall <br />include a blasting proposal providing the following details: <br /> <br />a. A drawing which shows the proposed blasting area, location of nearest hole <br />and distance to Railway structures, all with reference to the centerline of track. <br /> <br />b. Hole diameter. <br /> <br />c. Hole spacing and pattern. <br /> <br />d. Maximum depth of hole. <br /> <br />e. Maximum number of decks per hole. <br /> <br />f.
